    摘要: A voltage clamp protection circuit to protect against overvoltage conditions where there is insufficient current to blow a fuse. The voltage clamp protection circuit includes a voltage clamp and a thermal cutoff. The voltage clamp clamps any overvoltage to a clamping voltage. If an overvoltage condition persists for too long the voltage clamp dissipates a sufficient amount of heat to activate the thermal cutoff creating an open circuit that protects the rest of the circuit. The voltage clamp protection circuit may be used in combination with a variety of other protection circuits to provide increased protection.

    摘要: A wireless power transfer system with a remote device having a communication transmitter configured to initiate communications with a framing pulse to prevent noise from being mistaken for legitimate data. The communication system may employ a bi-phase modulation scheme, and the framing pulse may be generated to present no transitions in the communication signal during a specified period of time. The communication transmitter may produce the framing pulse by applying a load in the remote device. The present invention also provides a method for transmitting communication signals in a wireless power supply system including the general steps of: (a) preceding each communication with a framing pulse configured to present a bit sequence that does not exist in legitimate data communications, (b) maintaining the framing pulse for a period of time sufficient to effectively “reset” the communications receiver and (c) transmitting communications following the framing pulse.

    摘要: A drawer slide which is capable of moving in and out of the housing of a computer or other electronic apparatus is configured to receive an interface card which is connected into the circuitry of the computer when the drawer slide is in a fully inserted position. The drawer slide rides in a drawer guide which is secured to the computer structure. An interface connector is mounted on the drawer guide and engages a connector on the interface card for connecting the interface card to the remainder of the computer circuitry. A key lock mechanism prevents unauthorized movement of the drawer slide and the associated interface card out of the computer housing.
