摘要： A proximity sensor module used in an electronic device includes a combination sensing element and antenna, and a detecting circuit electrically connected to the combination sensing element and antenna. The combination sensing element and antenna is used to detect whether an external object is in vicinity of the combination sensing element and antenna according to capacitance changes of the combination sensing element and antenna in presence or absence of an external object in the vicinity, the detecting circuit detects the capacitance changes, and generates a signal associated with the changes to decrease or increase transmission power transmitted to the combination sensing element and antenna.

摘要： An interface circuit for connecting with a universal serial bus (USB) data cable includes a USB connector for connecting with the USB data cable, an over voltage protection (OVP) circuit connected to the USB connector, and a time delay circuit connected to the USB connector and the OVP circuit to control the OVP circuit. The OVP circuit is switched off in a predetermined delay time of the time delay circuit when the USB data cable is connected to the USB connector, and is then switched on after the delay time of the time delay circuit.
