Abstract: Per United States Federal Aviation Administration (FAA)'s long standing airworthiness regulation, Advisory Circular (AC), failures of all systems/components that are catastrophic must be “extremely improbable”. Advanced Flight Control Subsystem shall supplement current commercial passenger aircrafts' Flight Control Computers (FCC) to meet and exceed this requirement.

Abstract: A power supply is configured to limit its output power, converting an input voltage on a primary side into a bus voltage on a secondary side. A current-sense resistor detects a bus current output from the power supply to provide a current-sense signal. A bus switch is electrically connected to a secondary winding on the secondary side, configured to selectively supply power to the bus voltage. A power delivery controller controls the bus switch in response to the current-sense signal and a power detection signal on the secondary side. The power delivery controller provides a power threshold in response to the bus voltage, compares the power detection signal with the power threshold, and turns off the bus switch to stop supplying power to the bus voltage if the power detection signal exceeds the power threshold, thereby limiting the output power of the power supply.

Abstract: Disclosed are LED controllers for dimming. An LED controller includes a current driver, a pulse-width modulator, a feedback circuit, and a decoupling circuit. The current driver, selectively in response to a dimming signal, causes a driving current flowing through one LED string. The dimming signal is capable of defining a dimming ON period and a dimming OFF period. The pulse-width modulator generates a PWM signal to control a power switch, in order to buildup a driving voltage at a power node of the LED string. The PWM signal is generated in response to a compensation signal. The feedback circuit, based upon a feedback voltage from the light emitting device, drives a compensation capacitor to generate the compensation signal. The decoupling circuit defines a decoupling period at the start of the dimming ON period and causes the feedback circuit not driving the capacitor during the decoupling period.

Abstract: A control method is disclosed for light dimming. A dimming condition signal is provided to represent whether a light emitting device is expected to be emitting light. The duration when the dimming condition signal is at a logic value indicating the light emitting device is emitting light is a dimming-ON time, in which a close loop is provided to make a power converter convert electric energy to the light emitting device such that the light emitting device is capable of emitting light. A power-ON time is the duration when the power converter converts electric energy to the light emitting device. When the dimming-ON time ends and is less than a minimum power-ON time, the power converter continues converting the electric energy to the light emitting device so as to keep the power-ON time not less than the minimum power-ON time.
