Abstract: Fly-by-wire vehicle systems and related remote actuation systems and operating methods are provided for actuating a remote flight control component using an individual analog command signal communicated over an individual electrical cable or wire. An exemplary method involves logic, circuitry or other hardware at a remote actuation system receiving an analog input command signal, converting the analog input command signal to a rotational speed command in a commanded rotational direction based on a relationship between a current state of the signal characteristic and a reference state for the signal characteristic, converting the rotational speed command into a power conversion command based at least in part on the rotational speed command and the current state of the motor, and operating power conversion circuitry at the remote actuation system to provide power to the motor in accordance with the power conversion command to achieve the commanded rotation in the commanded rotational direction.

Abstract: A system (10) and method for monitoring the operational life and/or performance of one or more light-emitting diodes (LEDs) (20) based on sensed parameters are disclosed. The remaining life of each LED may be predicted by counting the clock cycles during which the LED-based light is activated. LED current and/or temperature measurements may be used to control the clock signal and, thus, to compensate the predicted life value. Furthermore, operational characteristics of the LED-based light may be monitored based on LED current and/or voltage measurements. Such characteristics may include performance (e.g., intensity) and failure conditions (e.g., open or short circuits).
