阅读说明：本技术 多功能触控笔 (Multifunctional touch control pen ) 是由 R·卡普兰 T·A·雅各波斯基 于 2018-11-09 设计创作，主要内容包括：一种触控笔包括细长壳体、从细长壳体的第一端延伸的尖端、以及安装在第二端上的三轴力传感器。第一无线发射器经由笔尖传送信号,笔尖基于该信号来与触摸屏的数字化仪传感器交互。三轴力传感器感测由用户压靠三轴传感器所施加的接触力。第二无线发射器传送由三轴力传感器感测到的输出。该触控笔进一步包括控制器,该控制器控制第一无线发射器和第二无线发射器的传输。(A stylus includes an elongated housing, a tip extending from a first end of the elongated housing, and a triaxial force sensor mounted on a second end. The first wireless transmitter transmits a signal via the pen tip, which interacts with a digitizer sensor of the touch screen based on the signal. The triaxial force sensor senses a contact force applied by a user pressing against the triaxial sensor. The second wireless transmitter transmits an output sensed by the triaxial force sensor. The stylus further includes a controller that controls transmissions of the first wireless transmitter and the second wireless transmitter.)
