A line card includes a plurality of subscriber line interface circuits, a plurality of interface lines, and a first overvoltage protector. The subscriber line interface circuits each have a first input terminal operable to receive power at a first positive reference voltage. The interface lines are each coupled to one of the subscriber line interface circuits for interfacing with subscriber lines external to the line card. The first overvoltage protector is coupled to the interface lines and referenced to the first positive reference voltage to provide overvoltage protection responsive to a voltage on at least one of the interface lines exceeding the first positive reference voltage.

A system and method for mirroring power over Ethernet (PoE) registers in physical layer devices (PHYs) over a single isolation boundary. PHYs in a PoE system can be arranged in a master/slave configuration. In this configuration, a master PHY can be designed to communicate with the power source equipment controllers via a single isolation device.

A telephone device includes a base, a light transmitter, a light penetrating element for penetrating light transmitter from the light transmitter, and a handset. When an end of the handset is on-hook with the base, the end of the handset reflects the light emitted from the light transmitter and penetrating through the light penetrating element back to the light penetrating element. The telephone device further includes a light receiver for receiving the light reflected from the handset when the end of the handset is on-hook with the base, a light concentrating element for concentrating the light emitted from the light transmitter to the light penetrating element, and a control unit for determining whether the end of the handset is on-hook with the base according to whether the light receiver receives the light reflected from the handset.

A magnetic-push slide cover driving device includes a slide seat having at least one slide guide section, a base seat connected on the slide guide section and reciprocally slidable along the slide guide section, at least one middle magnetic body disposed at a middle section of the base seat, and two movable members respectively pivotally disposed at middle sections of two sides of the slide seat. The movable members respectively have two opposite sides. The middle magnetic body is slidable between the opposite sides along with the base seat. Multiple magnetic bodies are arranged on each of the opposite sides. The magnetic bodies on the same side are such arranged that the poles of the same polarity are directed in the same direction. Accordingly, at a later stage of opening process of a slide cover, the magnetic-push slide cover driving device provides a push aid force for the slide cover.
摘要:
Proximity sensor, particularly for usage in an electronic mobile device, comprising at least one acoustic transducer adapted for receiving acoustic signals at least in parts of the frequency range of human audible sound and emitting and/or receiving ultrasonic signals for proximity estimation. The acoustic transducer preferably is a Micro-Electro-Mechanical-Systems (MEMS) microphone. Further, a method in an electronic device comprising an acoustic transducer is provided comprising the steps of generating at least one electric signal in the frequency range of ultrasonic sound, emitting at least one ultrasonic signal by means of the acoustic transducer; receiving at least one ultrasonic signal by means of the acoustic transducer; deducing from the at least one emitted ultrasonic signal and the at least one received ultrasonic signal at least the delay between emission of the emitted ultrasonic signal and reception of the corresponding ultrasonic signal.

The present invention discloses a sliding mechanism including a first board, a second board, a first fixed piece, a frame, a first elastic element and a first sliding element. The second board includes a first slot. The first fixed piece passes through the first slot to be disposed on the first board. The first elastic element is disposed in the frame. When the second board slides a first distance relative to the first board, the first sliding element slides along a first direction to press the first elastic element, so as to make the first elastic element generate a first elastic force. When the second board slides a second distance relative to the first board, the first sliding element slides along a second direction and makes the first elastic element release the first elastic force. It makes the second board slide automatically relative to the first board.
