Patent number: 9414459Abstract: A system and appertaining method calibrate a color LED light unit comprising at least first-, second-, and third-color LEDs, comprising: a) defining a target color on a color map to calibrate; b) selecting initial calibration coefficients associated with the target color; c) storing the initial or updated calibration coefficients in a non-volatile memory of the light unit; d) controlling the light unit to drive the LEDs to attempt to emit the target color, producing an attempted color, utilizing the calibration coefficients; e) measuring the attempted color to determine if it matches the target color within a predefined tolerance; f) if the attempted color matches the target color, then terminating the method; g) if the attempted color does not match the target color, then performing the following; h) selecting a color component; i) adapting at least one calibration coefficient associated with the selected color component; and j) performing (c)-(i) again.Type: GrantFiled: April 27, 2015Date of Patent: August 9, 2016Assignee: B/E AEROSPACE, INC.Inventors: Eric Johannessen, Andrew B. Walsh, Kevin Lawrence, Richard Waring, Jr.

Patent number: 8112213Abstract: A system, apparatus and method provide a means for controlling an electric brake actuator. An electromechanical actuator controller (EMAC) is configured to receive first data indicative of a desired braking force, second data indicative of a braking command generated by a brake input device, the second data different from said first data, and third data indicative of a braking mode. Based on the third data, the EMAC selectively uses the first data or the second data to control the actuator.Type: GrantFiled: April 24, 2009Date of Patent: February 7, 2012Assignee: Goodrich CorporationInventors: Eric D.
