摘要： A method of a portable electronic device for self-calibration of a proximity sensor. A background measurement is obtained by the proximity sensor and a detection threshold of the proximity sensor is adjusted based on the background measurement. The background measurement is a measure of a received signal when no signal is transmitted by the proximity sensor, and the detection threshold is associated with a sensitivity of the proximity sensor to environmental conditions. A source signal is emitted by the proximity sensor based on the adjusted detection threshold of the proximity sensor, and a return signal is received by the proximity sensor corresponding to the source signal. A function of the portable electronic device may be performed base don the received return signal.
摘要翻译：一种用于接近传感器的自校准的便携式电子设备的方法。背景测量由接近传感器获得，并且基于背景测量调整接近传感器的检测阈值。背景测量是当接近传感器没有传输信号时对接收信号的测量，并且检测阈值与接近传感器对环境条件的灵敏度相关联。基于调整后的接近传感器的检测阈值，由接近传感器发出源信号，并且与源信号对应的接近传感器接收返回信号。可以基于接收到的返回信号来执行便携式电子设备的功能。

摘要： A system and method for interaction between an electronic writing device (102) and a wireless device (104) includes the electronic device (102) being capable of generating a keystroke signal (106). The system and method further includes the wireless device (102) receiving the keystroke signal (106) and executing an operation (168) in response thereto. The electronic writing device (102) includes a motion sensor (110) that generates a motion displacement signal (116), a toggle switch (112) that generates an engagement signal (118), a pressure sensor (114) that generates a depression signal (120) and an optical sensor (128). The wireless device (102) includes a receiver (162) that receives the keystroke signal (106) and a processor (164) that executes an operation in response thereto or may provide for operating in a bar code mode, such that a bar code may be scanned and the keystroke signal including a bar code signal.
