20090096479 | System and method for automated detection of singular faults in diode or'd power bus circuits - A system automatically detects singular faults in diode or'd power bus circuit comprised of a plurality of diodes. The system includes a diode test circuit that selectively applies a voltage pulse to one of the plurality of diodes and detects the presence of singular faults based on the monitored response to the voltage pulse. | 04-16-2009 |
20120253556 | REDUNDANT TWO STAGE ELECTRO-HYDRAULIC SERVO ACTUATOR CONTROL - A flight control system includes a dual stage actuator for moving a control surface. Each stage includes several control valves that are controlled independently to provide a desired redundancy. A flight controller generates a position command that is indicative of the position desired for the control surface. A first communication link is provided between several flight controllers to share information. Each of the flight controllers forwards the position command to actuator remote processing unit. The actuator remote processing unit receives position commands and generates a command signal that controls movement of the actuator using the control valves. Each of the actuator remote processing units is linked through a second communication link. Feedback and balancing of the different control valves is provided by the visibility accorded each actuator remote processing unit by the second communication link. | 10-04-2012 |
20120253564 | INTEGRATED FLIGHT CONTROL AND COCKPIT DISPLAY SYSTEM - A Human Machine Interface includes a flight control system operable to communicate display data directly to a cockpit display system. | 10-04-2012 |
20120320475 | PERMANENT MAGNET ALTERNATOR MARGIN DETECTOR - A shunt regulated permanent magnet alternator voltage source includes a permanent magnet alternator, a shunt regulator, and a pulse width modulation controller. Also included is a load controller capable of detecting a PMA margin. | 12-20-2012 |
20140103955 | SYSTEM AND METHOD FOR AUTOMATED FAILURE DETECTION OF HOLD-UP POWER STORAGE DEVICES - A fault detection circuit is utilized to automatically detect faults in hold-up power storage devices. The fault detection circuit includes a hold-up monitoring circuit and a memory device. The hold-up monitoring circuit is connected to monitor output of the hold-up power storage device, wherein the hold-up monitoring circuit measures a duration of time that the hold-up power storage device provides sufficient power following a loss of normal power and detects faults based on the measured duration of time. The memory device is connected to store the duration of time measured by the hold-up power storage device following a loss of normal power | 04-17-2014 |
20140303812 | BACKUP CONTROL SYSTEM - An aircraft control system includes an effector module connected to a control input and a primary control module connected to the effector module. A microprocessor in the effector module provides a backup control path bypassing the primary control module when the primary control module is in a failed state. | 10-09-2014 |
