摘要： A remotely-controlled cable equalization system includes a control unit containing a non-volatile memory, a plurality of remote video display devices, each of which includes an adjustable cable equalization circuit, and an interface for connecting the control unit to each of the plurality of remote video display devices. Each of the plurality of remote video display devices includes a receiver for receiving a 12-bit digital code, from the control unit, through the interface. A 12-bit register is connected to the receiver and a 12-bit digital-to-analog converter is then connected to the 12-bit register, for receiving a 12-bit digital code from the 12-bit register and for converting the digital signal to an analog signal. The adjustable cable equalization circuit in each of the plurality of remote video display devices receives the analog signal from the 12-bit digital-to-analog converter and provides the necessary cable equalization for each of the plurality of remote video display devices based on the received analog signal.

摘要： A system on an aircraft that eliminates hot-swapping of circuit boards to prevent damage to the circuit board connector interfaces. The system supplies power to a circuit card only when there is an effective coupling between a circuit card connector and an opposite mating connector. A power control circuit responds to a card present signal which indicates when the circuit card connector is coupled to the opposite mating connector. A logic circuit converts the card present signal to a power supply enable signal. A main power supply receives the power supply enable signal and provides power to the circuit card only when the circuit card connector and the opposite mating connector are appropriately coupled.

摘要： A power supply inrush current control circuit includes a current-limiting resistor connected in series with a first relay, a second relay connected in parallel with the current-limiting resistor and first relay, a power factor correction stage connected in series with the parallel combination of first relay and current-limiting resistor, and second relay, a holdup capacitor connected to an output of the power factor correction stage and a DC/DC converter connected to the output of the power factor correction stage. A first timer is connected to the second relay, a second timer is serially connected to the first timer and to the power factor correction stage, and a third timer is serially connected to the second timer and to the DC/DC converter. Upon energization of the power supply by an AC voltage source, the first relay is activated so as to connect the current-limiting resistor to the AC voltage source, and after a predetermined period of time, the second relay is activated by the first timer so as to short out the current-limiting resistor.
