Various technologies and process flow step are described in detail now with reference to example as shown in drawings.It is described below In, numerous details are elaborated, in order to provide to the thorough of the one or more aspects and/or feature for wherein describing or mentioning Understand.However, it will be apparent to those skilled in the art that the one or more aspects for being described herein or quoting And/or feature can be implemented in the case where not having some or all of these details.In other cases, known Process steps and/or structure be not described in detail to will not obscure in the aspect and/or feature for being described herein or quoting It is some.

Moreover, this class process and method can quilts although process steps or method and step can be described according to sequential order It is configured to be suitble to order to carry out work according to any.In other words, any sequence or order for the step of can describing in the disclosure It itself does not point out to need to execute step in that sequence.In addition, although be described or imply for it is non-concurrent occur (for example, because One step is described after other steps), but may be performed simultaneously some steps.In addition, in the accompanying drawings by its description to mistake The diagram of journey, which does not imply, excludes other modifications and its modification, does not imply that any one step of shown process or its step is necessary for showing One or more examples of example, and do not imply that shown process is preferred.

This disclosure relates to which the event instance of one or more predetermined properties or mode occurs in physiological signal for identification Device and method.Specifically, it may be desirable to the example for identifying certain scramblings in physiological signal.For example, when physiology is believed When number such as PPG signal or electrocardiogram (ECG) signal measure the one or more aspects of cardiac cycle over time, the possible phase It hopes the one or more predetermined properties for finding heartbeat waveform and/or heart pattern, can represent corresponding present in cardiac cycle Characteristic.Physiological signal (for example, heart rate signal) can indicate one or more physiological parameters of user (for example, heart rate, heart rate are variable Property etc.).However, in fact, according to equipment and operation mode, the sensor for being configured as monitoring these physiological signals may be vulnerable to Movement or the influence of other noise sources, this may reduce the accurate of the practical cardiac cycle of measured signal expression user Degree.The method for the quality for improving measured signal may be present (for example, the output of the light source by increasing PPG sensor is strong Degree), but these variations are usually using power increased costs as cost.In battery powered equipment, increase for obtaining life The power of reason signal may reduce equipment available power for other purposes.

Example as described herein mainly discusses one using the PPG signal searching heart rate signal measured by PPG sensor Or many aspects, it is to be understood that, method discussed here can be used for searching one or more in any suitable physiological signal A predetermined properties, such as ECG signal, impedance cardiography (ICG) signal, cardiac muscle figure (BCG) signal, electromyogram (EMG) signal etc.. In these cases, which may include being configured as detecting one or more biographies of some or all of above-mentioned physiological system Sensor cell.

As described above, PPG sensor can be used to determine one or more physiologic informations of user.In citation form, One or more light sources and one or more photodetectors can be used in PPG sensor unit.When positioning PPG sensor unit makes When one or more light sources and one or more photodetector abuttings or the placed of adjacent user, one or more light sources can Emit light to illuminate the skin of user.Photodetector can receive and measure incident light on the photo-detector, and come for determining The amount (for example, the light for having transmitted, reflecting and/or having scattered and left user group) of the light of detector is reached from light source.By light The amount (for example, in the form of one or more signals) of the light of detectors measure can be based on by the amount of the light of the tissue resorption of user And change.The equipment can monitor the absorption to calculate one or more physiologic informations, such as heart rate.Blood volume in body vessel Can be used as a part of cardiac cycle with respect to variation and occur, and these opposite variations can lead to the tissue resorption by user Light amount variation.These opposite variations can be by PPG sensor measurement, to find the one or more aspects of cardiac cycle.Example Such as, PPG sensor unit can measure the timing and/or feature of each heartbeat, to provide the measurement of such as heart rate.It is one or more Measured light can be converted to the electric signal of instruction intensity by photodetector, and electric signal can be converted into PPG heart rate signal.

When the sensor measurement heart signal of such as PPG sensor, system and method described herein can recognize and infuse The case where one or more aspects of volume wherein measured signal meet one or more preassigneds.For example, letter can be analyzed Number to determine heart rate, and the system and method can be configured to the case where identification heart rate is more than heart rate threshold.In other situations Under, signal can be analyzed to check and a series of beating of heartbeats to the related one or more parameters of beating timing.For example, herein The system and method for description can recognize the case where variance measures being spaced between wherein beating meet one or more variance criterions.Know The example being spaced between not irregular beating can reflect one or more situations of user's situation bottom.

This disclosure relates to irregular in one or more signals (for example, physiological signal such as heart rate signal) for measuring The method and corresponding equipment of property or other predetermined properties.The equipment may include PPG sensor unit, the PPG sensor list Member is configured as detecting the multiple generation of the given event in sampling interval in measured signal using sampling regulation.Event It can be the example for meeting the signal of one or more standards.In some cases, when the quantity of generation meets, and threshold value occurs, Equipment registrable (for example, storage, notify user etc.) includes that the multiple of event occurs (together with the letter of the single appearance about event Breath) example.In some instances, equipment may include that can be used for providing one or more additional sensor (examples of additional signal Such as, the motion sensor of such as accelerometer and/or gyroscope).Signal can be used for sampling collected to help to control in regulation The timing and/or analysis of signal.For example, one or more motion sensors can be used to come when detection device is in harmonic motion shape State (that is, state when measured motion information is unsatisfactory for one or more movement thresholds), and equipment can equipment not Delay start measurement is when in harmonic motion state to improve measurement accuracy.In some variations, in addition to analysis comes from PPG sensor Signal except, it is necessary to analyzed in the corresponding standard of the one or more that meets equipment one or more additional signals (for example, From motion sensor), to determine the generation for the event that measured.The example of the disclosure further includes factor based on one or more The quantity of such as non-qualified measurement resets sampling regulation.

This section describes the representative applications according to disclosed method and device.These examples are provided merely to Addition context simultaneously helps to understand the example.Therefore, for a person skilled in the art it is evident that, can The example is practiced in the case where not having some or all of detail.In other cases, in order to avoid need not Strategic point obscures the example, and well known processing step has been described in detail.Other application is possible, so that following example should not be by It is considered as restrictive.

Figure 1A-Fig. 1 C is shown can be in the exemplary equipment for wherein realizing the disclosure.It may include touch screen that Figure 1A, which is shown, 124 illustrative mobile phone 136.Figure 1B show may include touch screen 126 exemplary media player 140.Fig. 1 C shows The exemplary wearable device 144 that may include touch screen 128 and band 146 can be used to be attached to user is gone out.Figure 1A-Fig. 1 C's Equipment is using the device and method for operating PPG sensor unit as disclosed.

Fig. 2 shows the bottom view of example electronic device, which includes for according to the disclosure Example determines the photodetector and light source of physiological signal.Equipment 200 may include sensor unit 204 and band 202, the band 202 It can be used for coupling sensor unit 204 (for example, attachment) to a part of user (for example, the wrist of user, hand, arm, leg Deng).Sensor unit 204 may include one or more light sources (for example, light source 208 and light source 210) and positioned at equipment 200 One or more detectors on surface) for example, photodetector 206).Equipment 200 and/or sensor unit 204 may be positioned to So that the skin of 206 adjacent user of light source 208 and 210 and photodetector.For example, equipment 200 can be maintained at the hand of user In or be bundled into the wrist of user, in addition to other possibilities.

Light source 208 and light source 210 can emit light.Transmitting light can be incident on the skin of user, and can be reflected back by light Detector 206 detects.Light emitted a part can be and light emitted by the skin, blood vessel and/or blood absorption of user A part can be returned photodetector 206.Sensor unit 204 may act as PPG sensor, and photodetector 206 is at any time Between the light that measures can be used for generating PPG signal.PPG signal can be monitored and analyzed to identify certain characteristics of signals as described above Occur.In some instances, light source can be configured to the light of transmitting different wave length (or wave-length coverage).For example, light source 208 can quilt It is configured to shine at green wavelength, and light source 210 can be configured to shine in infrared waves strong point.

When the light of different light sources transmitting different wave length, sensor unit may include that can detect at multiple and different wavelength One or more light detector elements of light (transmitting in this case, from different light sources can be division multiplexed).Except this Except or alternatively, one or more light detector elements are tuned (for example, using one or more filters) to measure not At the subset of co-wavelength light (for example, sensor unit may include be tuned to measure green light rather than at least the one of infrared light A light detector elements, and be tuned to measure infrared light rather than at least one photodetector of green light).It should be appreciated that Sensor unit may include any amount of light source and photodetector, and these elements can be in a device with any suitable Relative positioning.In addition, though being described as being utilized respectively the first wave length and second including green and infrared wavelength for example herein Wavelength, it is to be understood that, other than other possibilities, sensor unit can utilize any suitable wavelength for first wave Long, second wave length and any additional wavelength, such as feux rouges, green light, feux rouges, amber light and blue light.

When sensor unit 204 is configured as in multiple emitted at wavelengths and measurement light, sensor unit can be certain In the case of measured using different wave length.Can have different compromises, such as accuracy and power consumption using different wave length sensing Between compromise.For example, can be consumed using some sensor units that first wave length (for example, infrared wavelength) senses than utilizing the Two wavelength (for example, green wavelength) sense less power, but may be sensitiveer to certain noise sources such as user movement.At this In a little situations, it may be desirable to when the use of second wave length is limited in expectation raising accuracy.

In such example, sensor unit 204 be can be configured to when equipment is worn by the user periodically to sample Period (or continuously) sensed using first wave length.In general, during the given sampling period or during continuous sensing, sensing Device unit (for example, 5-20Hz) can be sampled photodetector at regular intervals.In some variations, between one or more Under, sensor unit can acquire at least two samples.At least one sample can be obtained while sensor unit emits light, And at least one sample can be obtained when sensor unit does not emit light (for example, its amount that can provide existing environment light Instruction).Sensor unit 204 can be used these measurement some or all of come provide one relevant to cardiac cycle or Multiple measurements (for example, heart rate), and when being used in body wearing (for example, wrist wearing) equipment, it may also be used on body/ Body vitro detection.It in these cases, can be that determining equipment is located on body or in the external adjustment equipment of body based on equipment Operation.When equipment, which is made, to be judged outside body, the one or more functions of equipment banned can be configured for power saving, safety or its Its purpose.When first wave length be visible spectrum except wavelength (such as infrared wavelength) when, such sensing, which can have, to be not easy to The additional advantage being easily noticed by the users.

When using first wave length (such as infrared wavelength) sensing have been used on body/body vitro detection when, this can be monitored A little signals are so as to one or many measurements of the smallest secondary power cost offer cardiac cycle.On the contrary, using second wave length The sensing of (such as green wavelength) can be preserved for certain purposes.In some cases, with use first wave length it is regular (or even It is continuous) sampling period compared, sensed during the regular sampling period of the lower generation of frequency using second wave length.In other feelings Under condition, it is sampled in combination with one or more extras function with second frequency.For example, equipment can be in tracking body-building (example Such as, the session of sports or movement) mode under operate, and sensor unit 204 can be at least part phase of body-building Between sensed using second wave length.By limiting the sensed quantity occurred under second wave length, which can save power.It is similar Ground, when equipment using sensor unit such as sensor unit 204 is to monitor physiological system when, it can be advantageous that by certain senses The accuracy of the raising of survey mode with may power cost associated with the sensing be balanced.

Event tracking

When the event in tracking monitored signal as described above, equipment be can be configured in given time period (for example, taking Sample interval) in detection the measuring signal from one or more sensing units in give characteristic multiple appearance.Event can be Meet the example of the signal of one or more standards during sampling interval.For example, the signal can be used for determining each secondary heartbeat Timing and/or characteristic.One or more characteristics of each secondary heartbeat or beating to timing of beating can be analyzed, and by itself and one or more A standard is compared, and equipment can when meeting relevant criterion registered events generation.For example, the equipment can be configured to The one or more irregular heart patterns of detection, it is such as described in more detail above.Therefore, with one or more corresponding standard comparings At least one parameter of signal may include but be not limited to the one or more aspects of user's heartbeat waveform, the heart rate of user, beating To timing etc. of beating.The standard may include that the heart rate for example measured is more than some value (that is, level threshold value).Event may include meeting The single of condition occurs and/or repeatedly occurs.

Fig. 3 A shows example process 300, by the process, multiple qualified events can be used to carry out registered events Example.Sample regulation start when, the sensor unit of such as PPG sensor unit can determine measured signal section whether It is qualified as event and the (step 301) of process 300, as herein referred as " determination " occurs.In some cases, it is sent out Raw determination includes the main measurement (mistake of one or more obtained using PPG sensor unit for obtaining one or more signals The step 302) of journey 300, analysis signal (for example, via processor or controller) (step 304) of process 300, and determine Whether signal meets one or more standards to be qualified as occurring (for example, the step 306) of process 300.Main measurement can To be the measurement (for example, using setted wavelength, emissive porwer, sampling rate etc.) carried out under first group of operating condition.

If signal is disqualification as generation, equipment can wait a certain amount of time before carrying out new determine (for example, at step 301) (step 308) of process 300.In these cases, can during subsequent determine (for example, At least one additional main measurement is made in step 302).In some variations, (for example, at step 304) signal analyzed It may include one or more additional main measurements and occur to determine the one or more measurements analyzed in step previous.At it In its modification, the one or more signals analyzed at step 304 can only include the survey carried out after previously determining Amount.Equipment wait time quantum can be it is scheduled, or can based on one or more factor (for example, the healthy shape of user Condition, the characteristic of user, historical data etc.) it is arranged.When signal is unsatisfactory for one or more standards and/or without enough information Come when determining whether for example one or more signals are qualified, one or more signals may be disqualification.It is also understood that some In the case of, equipment can determine (for example, carried out between step 301) it is one or many it is main measurement (or have difference The subsidiary of group operating condition), can be used due to other (on such as body/body vitro detection or body-building with Track), but be not used as that determining a part occurs.

If signal is qualified as occurring, equipment, which will can mainly be measured and (be measured at step 302), is counted as qualification (the step 310) of process 300 occurs.Processor can determine whether the quantity of qualified generation meets (for example, being greater than or equal to) one A or multiple generation threshold value (steps 312) of process 300, referred to herein as " threshold value determines ".If the quantity that qualification occurs It is unsatisfactory for (for example, being less than) generation threshold value, then equipment may wait for (for example, at step 308), then determine measured letter again Number whether it is qualified as event.

If the qualified quantity occurred, which meets, occurs threshold value, example (the step of process 300 of the registrable event of processor 314).Threshold value, which occurs, for one or more can be scheduled fixed numbers or factor (hereafter can further beg for based on one or more By).The equipment can be programmed to store various generation threshold values and corresponding scheduled event.In some instances, qualification can be sent out Raw one or many generations determination is weighted, so that can give certain qualified generations the power bigger than other qualified generations Weight, and can be adjusted accordingly generation threshold value.

As described above, qualification may include meet one or more standards (for example, one of the waveform of user's heartbeat or Many aspects, user heart rate, beating to beating timing etc.) signal section.Fig. 3 B shows curve graph, shows according to this A kind of modification that disclosed example detection qualification occurs.In these modifications, the section of PPG signal can be analyzed (in process 300 Step 304 place) to provide heart rate readings.When heart rate readings are above standard threshold value 352, the determination (In of qualified event can be carried out Step 306 place of process 300).The curve of Fig. 3 B is shown (to be shown relative to level threshold value 352 in different determining points with circle Heart rate value at out).For example, level threshold value 352 can be 120 beats per minute clocks (BPM), this can be programmable threshold.

In some in these modifications, it can be used at least one with the light source of infrared wavelength emissions (for example, in process 300 step 302 place) main measurement is carried out to provide PPG signal.The analysis of PPG signal optionally uses one or more Additional signal (for example, motion sensor from such as accelerometer), this can then improve the accurate of identified heart rate value Property.In addition to this or alternatively, the signal from motion sensor, which must also meet, is considered as one of qualified event for PPG signal Or multiple standards.When user remains static, (for example, wherein movement passes it is desirable that identifying raised heart rate Sensor does not indicate that it is generally desirable in the case where the activity of level threshold value heart rate or movement), this may be useful.

Each heart rate can be determined and be compared with level threshold value, and be more than the determination of threshold value (for example, positive events 354A and 354B) qualified generation can be designated as.As shown in Figure 3B, until time T1 terminates, no signal is qualified as The generation of event.At the 8th time point, the heart rate that user can be detected in sensing unit complies with standard threshold value 352 and can determine the Eight signals are qualified as positive events 354A.

It is greater than two (for example, five generations) in case of threshold value, then positive events 354A and 354B can not trigger event reality The determination of example, unless one or more additional qualified events occur before resetting samples regulation.For example, it can be five that threshold value, which occurs, Secondary generation.When detecting positive events 354A and 354B, which can determine and count during example determines (for example, twice Qualification occurs) it may be unsatisfactory for that threshold value occurs.As shown in FIG. 3 C, positive events 354A, positive events 354B, affirmative is occurring When event 354C, positive events 354D and positive events 354E, the registrable example 355 of equipment.

One or more occur threshold values can for scheduled fixed numbers or can based on one or more factor (hereafter further It discusses).The equipment can be programmed to store various generation threshold values and corresponding scheduled event.It in some instances, can be to there is money Lattice are mainly measured as at least one occurred and are weighted, and bigger weight occurs than other so that certain generations can be given, And it can be adjusted accordingly generation threshold value.For example, in the modification discussed above with respect to Fig. 3 B to Fig. 3 C, if the heart measured Rate is more than 150BPM, then the qualified weight occurred is multiplicable.In such example, example can be determined there are many mode and be registered It (for example, five times measure between 120 and 150BPM, or measure be higher than 150BPM twice, is measured for the third time for the example of event Higher than 120BPM).

In some instances, example can be registered based on a certain number of positive events occurred in predetermined time amount. Fig. 3 D is shown similar to those curve graph of Fig. 3 B and Fig. 3 C, and it illustrates a kind of such examples, wherein can will occur Threshold value is set as the event three times occurred in the reservation window.Positive events 354A can trigger the beginning of window 358A.As schemed Show, due to the event number in window 358A be unsatisfactory for occur threshold value, example associated with window 358A may not by Registration.Positive events 354B can trigger the beginning of the second window 358B.Since the positive events in window 358B are (for example, certainly Event 354B, positive events 354C and positive events 354D) quantity meet threshold value occur, therefore example 355 can be registered.Window Mouthful length can based on threshold value (being discussed below) similar factor and/or can be predetermined time period occurs.In some examples In, the length of window can be fixed, and threshold value, which occurs, can be conditioned (for example, being changed by processor dynamic).

In sampling another example of regulation, the section of PPG signal can be analyzed (at the step 304 of process 300) to mention It is measured for the timing property of the beating to PPG signal to beating timing.In these modifications, one or more standards of qualification generation It can be based on certain the horizontal scrambling of beating into beating timing.It can emit and measure infrared in PPG sensor unit In some modifications with two kinds of light of green wavelength, it may be desirable to using at least one with green wavelength transmitting light source (for example, Main measurement is carried out in the step 302) of process 300 to provide PPG signal.In some in these modifications, in subsequent generation The a certain amount of time is waited between determination, and (step 308) of process 300 may include the latent period without mainly measuring.It is waiting Can be carried out during period one or many subsidiaries (such as using infrared wavelength carry out one or many measurements) (for example, For body/body vitro detection or heart rate detection), but these measurement results can not can be used as a part of current sample regulation It is analyzed.However, the equipment can cancel given sampling regulation via one or many subsidiaries using determining outside body. As example earlier, when the corresponding generation threshold value of the quantity of qualified event satisfaction (or being more than), the registrable event of equipment Example.

When facility registration example, equipment can take one or more movements.In some cases, equipment can be created and be deposited The label or other records that storage event has been disclosed.In addition to this or alternatively, equipment can also store letter associated with event Breath.The example for the information that can be stored together with event includes but is not limited to the time of event, associated measuring signal, is associated The one or more measurements, the information from one or more motion sensors, the information (example about device location of measuring signal Such as, GPS data, altitude information etc.) and use information (such as, if content is just shown on screen).It can store about individual The information that qualification occurs, and the one or more measurements that may occur between qualified occur.In some cases, equipment can (for example, via tactile, vision and/or audible alarm) notifies user that example has occurred, and can further provide a user pass In the information of event.User can provide input (for example, via touch input on the touch-sensitive display of equipment) to indicate example The reason of be known (for example, example correspond to user move up and down suddenly) or unknown.If the reason of example, is Know, then equipment can cancel the example.If the reason of example is unknown, the executable one or more subsequent steps of equipment are all It such as notifies user and/or transmits information to host equipment (being discussed below).For example, host equipment can provide a user more Multi information.

Threshold value occurs

As described above, in some cases, equipment waits the qualified quantity occurred before being disclosed determining event Reach (or being more than) and threshold value occurs.Threshold value occurs can factor based on one or more.In some cases, threshold value occurs can be at least It is based in part on one or more characteristics of user.For example, in some variations, threshold value, which occurs, can be based at least partially on user Age.These situations it is some in, when user age increase when, occur threshold value may reduce.That is, threshold value, which occurs, to be User-programmable and/or based on one or more factor (for example, the situation of user, history metrical information etc.) automatically determine (and/ Or adjust) value.For example, the generation threshold value for giving user can be five, and when user reaches when user is less than given age Four can be changed to when the given age.The other information that user provides, such as medical conditions information and medication information, it can also be used to Threshold value occurs for given user setting.The generation threshold value of different user may change.

Threshold value, which occurs, may depend on the timing of qualified generation.In some cases, equipment can be counted only between given time Occur every the qualification of interior generation.For example, for the qualified event setting occurred within the scope of three hours threshold value can occur for equipment.Example Such as, five qualified events within three hour period may require a guarantee that registration (for example, notifying user) event, and at ten hours Five qualified events in period may underfrequency.For another example, equipment can be arranged based on the specific time in one day for closing The generation threshold value of lattice event.For example, heart rate raising can if detecting raised heart rate at the night that user is likely to sleep It can guarantee registered events.

In addition to this or alternatively, equipment is contemplated that the average time between qualified event.For example, when adjacent qualified generation Between average time at or below first level when, the first generation threshold value can be used in equipment, and can be in average time height Threshold value occurs using different second when first level.Under some cases in such cases, if qualified event occurs It must be close together, then equipment may need lesser amount of qualified event.

Movement

In some cases, which can be configured to monitor and/or characterize equipment moving.For example, equipment may include can Motion sensor (for example, accelerometer) for measuring device movement.In some cases, sports information can be used for Help handles and/or analyzes signal (for example, in step 304 shown in Fig. 3 A).

In addition to this or alternatively, in some cases, equipment can execute measurement based on motion information delay.For example, setting It is in harmonic motion state for may wait for equipment, to prevent (or minimum) from influencing the noise of measurement.Fig. 4 A is shown according to this public affairs That opens is exemplary for detecting the example process of motion information.According to the example of the disclosure, equipment as described herein is available Motion information is to determine one or more timings mainly measured and/or to determine whether signal section is qualified as qualified hair It is raw.Step 401,402,404,406,408,410,412 and 414 can be similar to the element of respective markers in Fig. 3, unlike, After waiting at step 408, equipment can measure the motion information (step 416) of process 400.According to motion information, equipment can Determine whether equipment is in harmonic motion state (that is, when measured motion information is unsatisfactory for one or more movement thresholds State) (the step 418) of process 400.If equipment is in harmonic motion state, equipment can carry out subsequent determine.In step It is rapid during 408 between main measurement there are in the case where latent period, when equipment detects harmonic motion state, equipment can be Step 402 place carries out one or many main measurements.If equipment is not in harmonic motion state, equipment can supervention after launch The waiting that takes a step forward (for example, until equipment is in harmonic motion state or meets other standards, as described below) of raw determination.Movement The use of information can help to the timing for promoting measurement when user is opposing stationary, this can help to the reliability of measurement and accurate Property.For example, removing non-user opposing stationary 10 minutes, otherwise equipment can not register example.

Occur after step 408 although Fig. 4 shows step 416 and 418, the example of the disclosure may include any The step 416 and step 418 that time occurs, including but not limited to step 408 simultaneously and/or before step 402.The disclosure If example may also include and detect non-harmonic motion state when executing step, interrupt and/or abandon one or more steps Suddenly.

In some instances, equipment can characterize movement based on activity level.For example, the motion state of user can be characterized For harmonic motion state, middle motion state and high motion state.Middle motion state can walk for such as user.When equipment detects When to middle motion state, equipment can continue disclosed example, but one or more can be set based on detected movement A standard, threshold value, waiting time or their combination.High motion state can run for such as user.When equipment detects When high motion state, equipment may wait for returning to middle motion state or harmonic motion state until user, then proceed to detection machine System.

In some instances, resetting when harmonic motion state may has not yet been reached in sampling regulation in maximum latent period, such as Shown in the example process of Fig. 4 B.Equipment may wait for the minimum latent period (step 426) of process 450.Equipment can determine certainly Last time has determined (step 401) from process 450 or since determining that associated last time mainly measures 402 with this Whether the duration is less than the maximum latent period (step 428) of process 450.If determined from last time generation or true with the generation Fixed associated last time mainly measure 402 since time be less than maximum latency, then equipment can measure and determine that equipment is It is no to be in the harmonic motion state (step 416 and step 418) of process 450.If before the time for reaching maximum latent period Equipment is not up to harmonic motion state, then (the step 424) of process 450 can be reset by sampling regulation.

When sampling regulation is reset at step 424, equipment can reset the qualified and/or non-qualified quantity occurred.One In a little situations, equipment can wait at least reset period attempting to determine before (or its subsequent main measurement).Some In the case of, the duration of reset period may depend on one or more conditions, such as battery levels and time of day (for example, If battery levels were lower than some amount in one day given time, bigger reset period may be used).In addition to this or optionally Determining Mean Speed occurs for ground, adjustable reset period (for example, the step 401) of process 400 to provide.For example, adjustable To provide, less than or equal to determining Mean Speed occurs once every hour, (this then may depend on such as battery longevity to reset period The factors such as life).For example, if initiate resetting before some period in (for example, one hour) during, device measuring, analysis And it carries out determining that equipment can wait additional time quantum (for example, three is small before attempting another physiological measurements four times When).

After having been subjected to reset period, equipment can initiate new generation determination and a corresponding new round mainly measures.In Under some cases, equipment can search one or more for should meeting before initiating the new primary measurement of a wheel in such as step 426 A starting standard.For example, in some cases, if equipment enter harmonic motion state (its can have in step 416 and 418 Harmonic motion determine identical or different standard), then equipment can initiate the main measurement of a new round.In addition to this or alternatively, The equipment can be configured to the execution subsidiary when subsidiary meets one or more standards and (it can for the main measurement of initiation It is chosen so as to indicate mainly to measure that qualified generation will likely be captured).In some cases, equipment can not initiate kainogenesis it is determining or It is mainly measured, until meeting one or more initiation standards.In other cases, equipment may wait for other a period of time, and And new generation determination or main measurement are initiated at this point, irrespective of whether meeting initiation standard.

Waiting time between reading

As described above, equipment raw determine of supervention can wait at least for non-zero time period (for example, in Fig. 3 A institute before after execution Step 408 place shown in the step 308 or Fig. 4 A shown).For example, equipment can disqualification as occur Setting signal section it Afterwards or qualification occur quantity be unsatisfactory for occur threshold value when waiting.The example of the disclosure may include include non-zero minimum wait week The latent period (that is, equipment can not attempt subsequent determine during minimum latent period) of phase.In addition to this or alternatively, Other factors (equipment moving as described above) can further postpone to initiate subsequent determine.Minimum latent period is optionally Whether the signal section depending on previous analysis is qualified as occurring.For example, if previous signal section occurs before formerly Be qualified as occurring during determination, then equipment is using the first latent period, and if previous signal section is first before Disqualification as generation during determining, then the second latent period can be used in equipment.In some instances, the second latent period The first latent period can be shorter than.In addition to this or alternatively, latent period may depend on generation and count and has mostly close to generation threshold value. For example, then equipment is using the first latent period in case of be greater than that threshold value occurs for (or being equal to) 90% is counted, and if Occur to count to be less than and occur the 90% of threshold value, then the second shorter latent period can be used in equipment.

In some cases, one or more conditions may make the resetting of sampling regulation (for example, the qualified quantity occurred returns Zero, threshold value occurs back to default value etc.).In these cases, equipment can be before re-initiating kainogenesis and determining at least etc. To reset period.In some instances, when specific (for example, predetermined threshold) quantity determine it is unidentified go out qualification When, sampling regulation can be reset.This may include when successive generations of first threshold quantity determine it is unidentified go out qualification generation and/or the Two number of thresholds are reset when determining (it does not need continuous in sampling regulation).It is including first threshold quantity and second In some examples of number of thresholds, second threshold quantity can be greater than first threshold quantity (for example, unidentified two occurred qualified out Secondary successive generation determination can lead to resetting, and the determination of generation three times for being scattered in entire sampling regulation can lead to resetting).Except this Except or alternatively, one or more additional conditions (for example, harmonic motion state as described above) may needed come after executing Supervention is raw determine in the case where, determine between maximum (that is, being greater than predetermined threshold) wait being spaced and can lead to resetting.

Confidence value

In some cases, the counting of qualified event can be based on confidence value.For example, before confidence value can be used for basis tightly To predict to give determining accuracy occurs for total motion history or other information in one period (for example, 2-4 minutes).Example Such as, in height movement setting, the heart rate determined during the analysis of PPG signal is less likely to be accurately (that is, the heart rate calculated There may be deviations between the practical heart rate of user), and in these cases, the identification that qualification occurs is less likely accurate Ground indicates the corresponding generation occurred in the cardiac cycle of user.Therefore, confidence value is used as the accuracy of signal measurement And the given expression that determining accuracy occurs.

It is more likely more accurate than the generation determination with more low confidence value that higher confidence value can indicate to occur to determine. In some instances, other than analyzed signal meets respective standard threshold value, the confidence value of calculating must also meet threshold value Level, to be counted as signal section to affirm qualification.Positive events continue (for example, by comparing qualified event Count relative to threshold value occurs and determine) it can indicate that probable value must notify user and/or register the scrambling (example of the example Such as, rapid heart rate).It in some instances, can be based on each respective confidence value for occurring to determine during example determines to it It is weighted.For example, can be weighted, so that less qualification is registered as into example when confidence value is higher, it is on the contrary .

Event type

The example of the disclosure may include the type based on event come to classifying.In general, occurring to determine includes hair (that is, analyzed signal meets preassigned) of existing analyzed signal qualification, is still unqualified (that is, signal is unsatisfactory for pre- calibration Standard or equipment cannot judge).In general, qualified event can be positive events.Positive events can be between sampling Every the example of the interior signal for meeting one or more first standards.Non- qualified event may include one or more negative events.In Under some cases, negative event can be to be unsatisfactory for the event of the first standard of one or more of positive events generation.In other feelings Under condition, in sampling interval, negative event must also meet one or more second standards.It in these examples, negate event Merely comprise the subset of non-qualified event.First occur threshold value can be associated with positive events, and second generation threshold value can whether It is associated to determine event.

Fig. 5 A shows the example according to the disclosure, the example process including detecting different types of event.In addition to such as Except described in lower, step 501,502,504,506,508,510,512,514 and 522 are similar to the correspondence markings of Fig. 3 A- Fig. 4 A Element.Equipment can be reset when a certain number of negative events occur.Equipment can wait initiation before determine Period (for example, at step 501).During determining at step 501, processor can analyze signal section to determine letter Number section is qualified as the generation of the first kind or the generation of Second Type.In some instances, initiating the period can basis Sampling regulation resetting is due to device power-on (for example, from sleep or closed state power-up) or due to one or more prompt weight The condition (for example, at step 522) set and it is different.

When the signal of (for example, at step 502) measurement is disqualification used as the generation of the first kind (for example, in step 504 With 506 in be determined as the generations of positive events) when, equipment can determine whether signal is qualified as the generation (example of Second Type Such as, it is determined as the generation of non-qualified event in the step 516 of process 500).The subset of non-qualified event is indicated in negative event In the case where, determine that negative event can be limited to by occuring as Second Type generation.Therefore, equipment is statistics available sends out as the first kind The quantity of raw qualified positive events, and statistics available qualification occurs as Second Type (for example, negating event shown in Fig. 5 B Quantity (the step 518) of process 500 of non-qualified (or negative qualified event) 556A).

Fig. 5 B shows the example for the sampling regulation summarized in Fig. 5 A.In these examples, one or more PPG can be analyzed Signal is to obtain heart rate value (for example, above with respect in example described in Fig. 3 A to Fig. 3 D).In in these examples some, When measured heart rate value meets or when more than the first level threshold value (for example, level threshold value 552), the hair of the first kind can occur It is raw, and when measured heart rate value is not up to the second level threshold value, the generation of Second Type can occur.For example, such as Fig. 5 B Shown, level threshold value 552 may act as the first level threshold value and the second level threshold value, so that the measurement for being higher than level threshold value 522 can It is confirmed as positive events (positive events 554A, 554B and 554C), and can be confirmed as lower than the measurement of level threshold value 552 no Determine event.And the example in Fig. 5 B is shown, the measurement equal to level threshold value be not considered as positive or negative event (for example, they Can be considered as the non-qualified event to contribute not towards the second generation threshold value), it is also understood that in other cases, according to Selection to the boundary condition of level threshold value 552, these measurements can be considered as positive or negative event.

Fig. 5 A is returned to, if the quantity that qualification first occurs is unsatisfactory for (for example, being less than) first and threshold value occurs, which can It is waited before (for example, at step 501 of process 500) (for example, in step 508) making subsequent determine.Similarly, If the quantity that qualification second occurs is unsatisfactory for the second generation threshold value, processor can wait before making subsequent determine (for example, in step 508).If the quantity that qualification second occurs, which meets (or being more than) second, occurs threshold value (for example, in process 500 step 520 determines), executable resetting regulation (the as described below) (step 522) of process 500 of processor.In some examples In, second occurs threshold value can occur threshold value lower than first.

For example, the first generation threshold value can be associated with positive events, and five generations of positive events can be set to. Second occurs threshold value can be associated with negative event, and can be set to the generation three times of negative event.As shown in Figure 5 B, The measurement of user's heart rate can lead to the qualified several times of following sequence and occur: positive events 554A, positive events 554B, negative event 556A, negative event 556B, positive events 554C and negative event 556C.The 15th measured place, in identification negative event In the case where 556C, equipment can determine that the quantity of negative event meets second and threshold value occurs.Although three measurements are qualified as Positive events, but since a certain number of negative events have occurred, equipment can continue to reset regulation in step 522.Hair The negative event of raw certain quantity can indicate that detected raised heart rate may be due to another except user's heart rate It caused by source (for example, noise), or may be due to caused by the rapid fluctuations of heart rate.

In some instances, equipment can search the different types of positive or negative event including multiple level threshold values.Example Such as, the first level threshold value 552 can be used in the negative event of the first kind, and the second mark can be used in the negative event of Second Type Quasi- threshold value 553.The generation of the negative event of the first kind can add in different ways with the generation of the negative event of Second Type Power, so that in step 522, it is more less than the negative event between level threshold value 552 and level threshold value 553 to be lower than level threshold value 553 negative event can lead to resetting regulation (for example, by the weighting of negative event and/or by occurring with multiple negatives Threshold value).This is useful when distinguishing following situations: in some cases, a series of measurement hearts rate (or other parameters) May be substantially compatible, but the not ipsilateral of threshold value may be fallen in, in some cases, a series of measurement hearts rate may more significant earthwave It is dynamic.

Multiple measurement types

In some instances, equipment can be configured to execute both main measurement and subsidiary, wherein main measurement can Reading including using first group of operating condition of PPG sensor unit, and PPG sensor unit can be used in subsidiary Second group of different operating conditions.For example, primary measurement may be more more acurrate than secondary measurement and/or less sensitive to noise, but More power may be consumed.In these cases, equipment is able to carry out frequent secondary measurement, but may want to limitation and use Primary measurement reduces the number of the example of strain on battery (for example, less frequently).Equipment can be true based on battery life Determine battery life and is selected between primary or secondary measurement.That is, equipment can PPG sensor unit different operation condition it Between switch, wherein operation mode can factor such as battery life based on one or more.

For example, the light source with the wavelength (or wave-length coverage) different from the wavelength of primary measurement can be used to carry out secondary Measurement.For example, mainly measurement (for example, using the infrared light supply and transmitter of lower-wattage) can on above-mentioned body/body outside It detects in conjunction with and more frequently carries out.It can be used main measurement to detect the first example of potential event or the example of predetermined quantity (for example, after resetting samples regulation)；The equipment is changeable or activates one or more components, is surveyed with using subsidiary Amount heart rate (for example, using the light source and transmitter of the higher precision to work with green wavelength, or different sensing units is used, Those of be such as described in more detail above).In some cases, main measurement using subsidiary can determine Between be movable, and can be used for other analyses from the information mainly measured.

Fig. 6 A shows the example according to the disclosure, uses main and subsidiary example process.Except described below Except, the step in Fig. 6 A is similar to the element of correspondence markings in Fig. 3 A- Fig. 5.At the step 601 of process 600, can be directed to makes The signal section obtained with one or many main measurements, it is determined whether met one or more condition thresholds.Specifically, Processor can determine from whether the signal mainly measured meets the condition threshold (step 616) of process 600.Condition threshold can base Whether guarantee using subsidiary in condition.For example, meet condition threshold can with the analysis phase from the signal mainly measured The increase of associated confidence value is associated.If being unsatisfactory for condition threshold from the signal mainly measured, equipment can into The subsequent main measurement of row is (for example, wait (for example, at step 608) before step 601).If from the letter mainly measured Number meet condition threshold, then equipment, which can be performed, one or many determines (for example, at step 603).In these modifications, Determination, which occurs, can be used one or many subsidiaries to obtain one or more signals (step 618) of process 600.Processor Or controller can analyze signal (step 605) of process 600 and at least one ginseng that can determine the signal from subsidiary Whether number is qualified as the generation (step 620) of process 600 of event.

If signal is disqualification as generation, equipment can wait for the first amount time before carrying out subsequent determine (for example, at step 618) (step 626) of process 600.If signal is qualified as occurring, equipment can survey auxiliary Amount (for example, measuring at step 618) is counted as the qualified generation (step 622) of process 600.Processor can determine qualified generation Quantity whether meet that (or being more than) is one or more to occur threshold value (steps 624) of process 600.If the quantity that qualification occurs It is unsatisfactory for (for example, being less than) generation threshold value, then equipment may wait for (for example, at step 626), then carries out subsequent auxiliary and surveys Amount.If the qualified quantity occurred, which meets (or being more than), occurs threshold value, processor registrable example (the step of process 600 614)。

It is waited before carrying out subsequent subsidiary after measuring at the first time, equipment can be determined whether to have been subjected to for the second time Measure (the step 628) of process 600.If having had been subjected to the second time quantum, it is one or more main that equipment can switch to execution It measures (for example, at step 602).In some instances, step 628 can the quantity based on periodicity or subsidiary, to replace Generation or supplement determine whether to have been subjected to the second time quantum.In some instances, item is unsatisfactory for even if from the signal mainly measured Part threshold value (for example, determining at step 616), switching equipment can also be with periodic intervals to execute one or many subsidiaries It carries out.

For another example, which can be configured to carry out subsidiary during non-harmonic motion state, and can detect it is low It switches to when motion state and is mainly measured, or vice versa.In addition to this or alternatively, can relative to subsidiary, By different sampling rates (under prevailing conditions) for mainly measuring.In some instances, subsidiary may include and mainly survey Different one or more operating parameters are measured, while realizing identical operating condition (for example, result).

In some instances, equipment, which can be used, upgrades regulation gradually to detect one or more of heart rate signal irregularly Rhythm.Gradually upgrading regulation can be object procedure, wherein activating main measurement in response to meeting specific criteria.Fig. 6 B is shown Exemplary gradually upgrade regulation according to the disclosure is exemplary.Process 650, which can begin at, monitors user using optical sensing unit The heart rate (step 654) of process 650.Optical sensing unit produces one or more heart rate signals of instruction user's heart rate. Optical sensing unit can check heart rate signal at a predetermined interval to determine whether heart rate signal includes one or more irregular sections Play (process 656 of process 650).If irregular rhythm is not detected in heart rate signal, optical sensing unit can continue Monitor the heart rate (step 654) of process 650 of user.The example of the disclosure includes the step 654 for including and step in step 652 656, as optional step.

If detecting the irregular rhythm in heart rate signal, can initiate gradually to upgrade and since step 658 Regulation.In some cases, other factors can be based on, the order such as received from processor (is given birth to for example, inputting from user At) Lai Faqi gradually upgrades regulation.

In step 658, gradually upgrading measurement can be executed within a certain amount of time.In some cases, gradually upgrading is surveyed Amount may include using the operating condition for being different from the operating condition used in step 654.In some instances, different operation item Part may include in step 658 in sensing unit using being different from for one of those of monitor heart rate in step 654 or Multiple optical components.For example, gradually upgrading measurement may include using one or more green emitters (that is, being configured in green The optical transmitting set to shine in wave-length coverage) and corresponding photodetector.The heart rate signal monitored in step 654 may include using One or more infrared transmitters (that is, being configured to the optical transmitting set to shine in infrared wavelength range) and corresponding light detection Device.For another example, the gradually upgrading measurement in step 658 may include identical optical transmitting set and photodetector in operation and step 654, But there is higher sampling frequency.

Optical sensor for gradually upgrading measurement can generate instruction user's heart rate gradually upgrading in measuring section One or more signals.System can determine the irregular rhythm (step 660) of process 650 whether is detected in heart rate signal. If detecting the irregular rhythm in heart rate signal, which can increase the quantity of (for example, being incremented by) determination certainly.This sets It is standby to can be determined whether that the affirmative for having been carried out number of thresholds determines the (step 662) of process 650.Certainly determination is to be indicated Really the determination of the positive events of irregular rhythm is detected.If the affirmative that number of thresholds has occurred determines that equipment is for referring to Show (for example, memory is recorded in example, is transmitted to separately via wired or wireless communication to the instruction of user over the display The notice etc. of one equipment).

If the affirmative that number of thresholds has occurred determines, the equipment registrable example (step 664) of process 650.If The affirmative that number of thresholds not yet occurs determines that then equipment can wait for the second time in step 666, then proceed to step 668.In step 668, equipment can determine whether had been subjected to the third time since last time gradually upgrades measurement.If it is not, Then equipment may wait for until detecting the harmonic motion state (step 674) of process 650.Once detecting harmonic motion state, equipment The just repeatable gradually upgrading measurement (step 658) of process 650.If detecting harmonic motion state, equipment is before proceeding The extra time amount since last time gradually upgrades measurement (step 668) is may wait for.

If having had been subjected to the third time since last time gradually upgrades measurement, equipment can be based in given time period Upgrade the quantity of measurement gradually the (step 670) of process 650 at the first time is arranged.For example, if last gradually upgrading is surveyed Amount was executed before more than one hour, then equipment can be reduced at the first time to avoid the long duration between measurement.
