Patent number: 11018425Abstract: A system and method for operating a system including at least one active electronically scanned array (AESA) element incorporates drain voltage amplifier control (DRAVAC) to maintain the power amplifiers of the AESA elements at a constant gain compression level. A processor of the AESA system may dynamically program, monitor, or adjust each individual array element or component thereof. As the RF output power of the power amplifiers varies, constant gain compression is achieved by dynamically adjusting the RF input power and drain voltage to the power amplifiers. An AESA element may incorporate built-in self-test circuitry for detecting faults in the power supply to the power amplifiers as well as calibrating and calculating RF output power for a given input power by controlling the bias of a pass device serving as the amplifier current source.Type: GrantFiled: May 1, 2015Date of Patent: May 25, 2021Assignee: Rockwell Collins, Inc.Inventors: Michael L. Hageman, David W. Cripe, Robert A. Kertis, Bryan S. McCoy, Russell D. Wyse

Patent number: 9991593Abstract: An Electronically Scanned Array (ESA) antenna is controlled via an optical domain without electrical conductors on the ESA Printed Wiring Board (PWB). Distribution of the control signal occurs over pulses of light through an optical medium separate from the ESA PWB. External to the ESA PWB are one or more optical wave guides functional as communications channels which connect the ESA optical receivers/transceivers with transmitters/transceivers interfaced to a system controller. The ESA is divided into groups of elements with serial busses and discrete signals driven by local controllers. The local controller for each group of elements may include one or more optical receivers (unidirectional) or transceivers (bidirectional). This concept offers a trade in electrical complexity associated with an ESA PWB for an additional manufactured medium redundantly supplying the control signal to the ESA as well as routing the RF data signal from the ESA to the system controller.Type: GrantFiled: December 19, 2014Date of Patent: June 5, 2018Assignee: Rockwell Collins, Inc.Inventors: Adrian A. Hill, Jeremiah D. Wolf, Bryan S. McCoy, Michael C. Meholensky, Anders P. Walker

Patent number: 9496296Abstract: The present disclosure is directed to optically-tuned electronic components including one or more layers of photosensitive semiconductive materials. In some embodiments, an optically-tuned electronic component includes a plurality of device layers have different bandgap characteristics. One or more selected layers can be optically activated (i.e. made substantially conductive) by illuminating at least a portion of each selected layer with illumination having a wavelength shorter than or substantially equal to the activation wavelength of each selected layer. Accordingly, various parameters can be tuned or a circuit can be switched between alternative paths by providing one or more selected wavelengths of illumination.Type: GrantFiled: December 20, 2013Date of Patent: November 15, 2016Assignee: Rockwell Collins, Inc.Inventors: Don L.

Patent number: 9136078Abstract: An electromechanical switching system includes a first conductive portion and a second conductive portion. The first conductive portion includes a conductive stationary end and a conductive floating end, connected by a shape memory alloy (SMA). When an input stimulus current is applied to the SMA, changes in the SMA urge motion of the conductive floating end of the first conductive portion toward the second conductive portion, which in turn causes a change in the state of the electromechanical switching system. The input stimulus current may be calculated to satisfy a given response time requirement.Type: GrantFiled: September 24, 2007Date of Patent: September 15, 2015Assignee: Rockwell Collins, Inc.Inventors: Gerard A. Woychik, Ryan J. Legge, Bryan S. McCoy
