Appl. No.:

12/393304

James E. Flatt - Foothill Ranch CA, US
David J. Gurrola - Fillmore CA, US
Bruce W. Behar - Pasadena CA, US
Daniel T. Nguyen - Irvine CA, US

International Classification:

B64C 13/24
B64C 13/00

US Classification:

244 994, 244 999

Abstract:

An electromechanical actuating assembly () can have a redundant design with a first electric motor (A) providing actuator-moving power via a first drive train (A) and a second electric motor (B) providing actuator-moving power via a second drive train (B). A first decoupling train (A) can transmit decoupling power to decouple the first drive train (A) from the actuator () and a second decoupling train (B) for transmit decoupling power to decouple the second drive train (B) from the actuator (). The assembly () is operable in a fault-tolerant mode wherein actuator-moving power is transferred only through one drive train (A/B) and the other drive train (B/A) is decoupled from the actuator ().

Abstract:

Systems, methods, and apparatus for automated close-loop electromagnetic (EM) datalink testing are disclosed. In some embodiments, the disclosed method involves routing, by a user simulator, at least one user input data and at least one user control command to a controller. The method further involves encrypting, by an encryption device(s), at least one user input data to generate at least one encrypted user input data. Also, the method involves transmitting, by a first radio, at least one encrypted user input data to a second radio via an EM signal(s); and receiving, by the second radio, at least one received encrypted user input data. Additionally, the method involves decrypting, by the encryption device(s), at least one received encrypted user input data to produce at least one received user input data. Further, the method involves processing, by the user simulator, at least one received user input data to generate a status report.
