[ technical field ] A method for producing a semiconductor device

The present invention relates to an information retrieving apparatus, and more particularly, to an information retrieving apparatus having a plurality of dials for selecting contents to be marked with information.

[ background of the invention ]

When police officers perform police work, recording is often required for searching for evidence to preserve relevant evidence. Therefore, the police guard can capture the media data such as the surrounding environment image, sound and the like by wearing the information capturing device to assist the police work when going out, and the media data recorded by the information capturing device can also record the scene situation when the event happens, so as to provide evidence demonstration and clear responsibility in the future.

At present, in use, in order to quickly identify which kind of event the recorded audio-visual information is related to after the recorded audio-visual information is taken out of the file, such as a traffic accident, a robbery event and the like, a quick key can be set for one-key setting. However, due to the variety of events, if a plurality of keys are to be arranged by using the shortcut key, the size of the panel space is limited, which is inconvenient.

[ summary of the invention ]

In one embodiment, the invention provides an information capturing device, which includes a housing, a turntable, a magnet ring, a circuit board, an audio/video recording unit, a control unit, and a hall sensor. The rotating disc is rotatably arranged on the shell. The magnet ring is arranged between the shell and the turntable and provided with a plurality of magnetic poles, and the magnetic poles with different polarities are arranged along the ring shape in a staggered mode. The circuit board is arranged in the shell, and the audio-video recording unit is arranged on the circuit board and embedded on the shell. The control unit is positioned in the shell, arranged on the circuit board and coupled with the video recording unit through the circuit board. The Hall sensor is positioned in the shell, and the corresponding magnet ring is positioned on the circuit board and is coupled with the control unit through the circuit board.

Therefore, after the information acquisition device finishes recording the audio and video, the turntable can be operated to rotate to the mark mode to be selected so as to mark the information type of the recorded audio and video. By arranging the rotatable turntable, when the mode to be marked is selected, the mode can be rotated, and only one turntable needs to be arranged on the shell. The magnet ring is arranged on the turntable and matched with the Hall sensor, and the control unit can judge and further switch the marking mode by sensing the magnetic field change during the switching between different magnetic poles on the magnet ring. In addition, because the magnetic field change sensing mode is used for controlling, the magnet ring positioned outside the shell and the Hall sensor positioned in the shell can mutually sense without breaking holes on the shell, so that the waterproof requirement is met.

[ detailed description ] embodiments

Referring to fig. 1 to 4, fig. 1 is a schematic diagram of an information capturing apparatus according to an embodiment of the present invention, fig. 2 is an exploded view of the information capturing apparatus according to the embodiment of the present invention, fig. 3 is a block diagram of the information capturing apparatus according to the embodiment of the present invention, and fig. 4 is a partially enlarged and exploded schematic diagram of the information capturing apparatus according to the embodiment of the present invention. The information capturing device 1 of the present embodiment includes a housing 10, a turntable 20, a magnet ring 30, a circuit board 40, an audio/video recording unit 50, a control unit 60, and a hall sensor 70.

As shown in fig. 1 to 3, the circuit board 40 is disposed in the housing 10, and the circuit board 40 is provided with an audio/video recording unit 50, a control unit 60 and a hall sensor 70. The video recording unit 50 may include, but is not limited to, a camera lens 51 and a microphone 52. The camera lens 51 and the microphone 52 are disposed on the circuit board 40 and embedded in the housing 10. The microphone 52 has a signal processing circuit (not shown) capable of generating a corresponding sound signal (digital signal) from the environmental sound (physical sound wave). The camera lens 51 can record images to capture environmental images.

The control unit 60 is also located in the housing 10, disposed on the circuit board 40 and coupled to the video recording unit 50 via the circuit board 40. After receiving the recording start signal, the control unit 60 controls the audio/video recording unit 50 to capture information, capture environmental sound through the microphone 52 and capture environmental image through the camera lens 51, and combine the environmental sound and the environmental image into environmental information.

After the information retrieval is completed, the information retrieval device 1 of the embodiment can mark the retrieved information, so as to facilitate the subsequent file reading and fast classify each information. For example, the marking modes of traffic accidents, gunshot events and the like can be set, after the information acquisition is completed, the corresponding mark is selected according to the information content, and then each piece of information can be marked quickly, so that the corresponding information can be classified and found quickly in the subsequent processing.

Next, the structure of the jog dial for selecting the marking pattern and its principle will be described in detail. Referring to fig. 1 and 2, the turntable 20 is rotatably disposed on the housing 10. As can be seen from fig. 1, the turntable 20 is rotated for the convenience of operation of a user, and the turntable 20 includes a plurality of operation portions 21 on a side surface away from the housing 10. Here, the operation portion 21 is a concave groove structure, but may be a convex protrusion structure, a dot protrusion structure, a rough surface, or the like, as long as it can provide a certain friction force with different hand feeling.

The magnet ring 30 is located between the housing 10 and the turntable 20. In the present embodiment, as can be seen from fig. 4, the magnet ring 30 is embedded inside the turntable 20, and the magnet ring 30 rotates along with the operation of the turntable 20. The magnet ring 30 has a plurality of magnetic poles, and the magnetic poles with different polarities are arranged along the ring shape in a staggered manner. For example, in the present embodiment, the magnet ring 30 is formed by alternately surrounding a plurality of N poles and S poles. The number of poles on the magnet ring 30 can be set according to the number of stages to be adjusted. For example, if 6 marking patterns are required, 6 magnetic poles, i.e., three sets of N-pole and S-pole, may be provided, and one magnetic pole is provided on the magnet ring 30 every 60 degrees, so as to form a magnet ring 30 in which the N-pole, S-pole, N-pole, and S-pole are surrounded by 360 degrees, but not limited thereto.

The hall sensor 70 disposed in the housing 10 corresponding to the magnet ring 30 is disposed on the circuit board 40 and coupled to the control unit 60 through the circuit board 40. In the present embodiment, the hall sensor 70 is a hall sensor capable of sensing two axial magnetic force changes simultaneously. The hall sensor 70 senses a magnetic force variation of a first axis and a magnetic force variation of a second axis and outputs a sensing signal and a steering signal to the control unit 60 according to the magnetic force variations. For example, the first axis may be parallel to the axial direction of the hall sensor 70, and the second axis is perpendicular to the axial direction of the hall sensor 70, i.e. the first axis is different from the second axis, and the first axis and the second axis may be perpendicular to each other.

When the magnet ring 30 is rotated to generate a magnetic pole transition (e.g., N pole to S pole or S pole to N pole) or between magnetic pole transitions (e.g., at the boundary between N pole and S pole), the direction of the magnetic field lines passing through the hall sensor 70 will change accordingly. The hall sensor 70 will generate a corresponding sensing signal according to the magnetic force variation and transmit the sensing signal to the control unit 60 for counting, so as to determine that the rotating segments are now rotated, and find a corresponding mark mode. During operation, if the rotating head is rotated to rotate reversely, the hall sensor 70 can detect and output a turning signal and a sensing signal to the control unit 60 according to the magnetic force variation, so as to determine the currently-turned marking mode.

Thus, by sensing two axial hall sensors 70, only a single hall sensor 70 is provided to sense the magnetic force variation, and a plurality of single axial hall sensors are not required.

Referring to fig. 2 and 4, the information capturing apparatus 1 may further include an elastic element 80 disposed on the housing 10. In the present embodiment, the elastic member 80 is provided on the outer surface side of the housing 10. The housing 10 has a receiving groove 11 on its outer surface for receiving and positioning the elastic member 80. In this embodiment, as can be seen from fig. 2 and 4, the elastic element 80 is a V-shaped elastic metal member. Therefore, the housing 10 has a substantially V-shaped receiving groove 11 on the outer surface thereof. After the elastic element 80 is accommodated in the accommodating groove 11, a fixing element 12 can be used to fix the elastic element 80 at the corresponding position. At this time, the elastic member 80 is elastically deformable only in the vertical direction as shown in the drawing by the stopper action of the fixing member 12 and the accommodating groove 11.

Next, as shown in fig. 4, the side of the rotating disc 20 facing the casing 10 includes a plurality of positioning slots 22, and one end of the elastic element 80 is selectively received in one of the plurality of positioning slots 22. In the present embodiment, the positioning groove 22 is also configured as a V-shaped groove corresponding to the shape of the elastic element 80. Thus, when the operation dial 20 rotates, the side wall of the positioning slot 22 pushes the elastic element 80 to move upward in the drawing due to the rotation of the positioning slot 22. When the positioning groove 22 is rotated to the next one, the elastic element 80 will be restored under the action of the elastic restoring force, so that the V-shaped end of the elastic element 80 is accommodated in the next positioning groove 22 again. In the process of rotation, due to the deformation and the recovery of the elastic element 80, the operation hand feeling is also brought to the user, so that the user can rotate only one position at a time, or the user can know that the user rotates a plurality of positions through the operation hand feeling in the process of rotation.

In order to allow the user to determine the rotation of the plurality of marking patterns by the operation handle, the number of the positioning slots 22 may be the same as the number of the magnetic poles, and each positioning slot 22 corresponds to exactly one magnetic pole on the magnet ring 30, and each positioning slot 22 corresponds to exactly the center of one magnetic pole for more accurate sensing. Since the magnetic field at the center of the magnetic pole is relatively single in direction (directly toward or away from the hall sensor 70), being rotationally positioned at this time, it can be unambiguously sensed that the magnetic field has changed.

In other embodiments, the number of the positioning slots 22 may be twice as many as the number of the magnetic poles. In this aspect, each positioning groove 22 corresponds to a center of a magnetic pole or a junction of two magnetic poles. The hall sensor 70 can generate a sensing signal according to the magnetic force change at the center of the magnetic pole or the joint of the two magnetic poles. Therefore, the required integer adjustment can be achieved only by setting half of the number of the magnetic poles corresponding to the number of the marking modes.

In summary, after the recording of the audio/video is completed by using the information capturing device, the turntable can be operated to rotate to the mark mode to be selected, so as to mark the information type of the recorded audio/video. By arranging the rotatable turntable, when the mode to be marked is selected, the mode can be rotated, and only one turntable needs to be arranged on the shell. The magnet ring is arranged on the turntable and matched with the Hall sensor, and the control unit can judge and further switch the marking mode by sensing the magnetic field change during the switching between different magnetic poles on the magnet ring. Furthermore, because the magnetic field change is sensed and controlled, the magnet ring positioned outside the shell and the Hall sensor positioned in the shell can mutually sense without breaking holes on the shell, and the waterproof requirement can be achieved.

Although the present invention has been described with reference to the foregoing embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
