Abstract: An electronically controlled grade crossing gate system and method. The system includes a gate arm, a gate arm moving assembly, a position sensor assembly and a controller. The gate arm moving assembly is configured to move the gate arm and the position sensor assembly is configured to sense a position of the gate arm. The position sensor assembly is a non-contact position sensor assembly. The controller is coupled to the gate arm moving assembly and the position sensor assembly and it is configured to receive an incoming command related to the gate arm. The controller activates the gate arm moving assembly in response to the incoming command and communicates with the position sensor assembly to monitor the position of the gate arm.

Abstract: A modular avionics system for an Unmanned Aerial Vehicle (UAV) has a control module that executes flight control and vertical and lateral guidance algorithms to generate control commands. A data link module communicates with a remote control station and receives control commands from the remote control station. A data acquisition module communicates with the control module and the data link module. The data acquisition module is configured to receive and process data from one or more onboard sensors and to actuate a plurality of servo motors in response to control commands. A switching module selectively couples the data acquisition module to the control module or to the data link module responsive to an input from the remote control station to respectively switch between a fully autonomous mode of UAV operation and a manual mode of UAV operation. Power may be provided by a power module.

Abstract: A method of detecting onset of a gas turbine condition, such as compressor stall, includes receiving data indicative of an operating parameter of a compressor of the gas turbine. The method also includes performing a wavelet transformation on the data to generate wavelet transformed data. The wavelet transformation is configured to affect a processing characteristic regarding a performance of the wavelet transformation. Features indicative of onset of the gas turbine condition in the wavelet transformed data are then identified to provide an indication for controlling the gas turbine to prevent compressor stall from occurring. A system for detecting onset of compressor stall in a gas turbine includes a sensor for providing data indicative of an operating parameter of the compressor and a processor for performing a wavelet transform on the data to identify features of the optimized wavelet transformed data indicative of onset of stall.

The method comprises selecting a first device from information of the topology of the control network. The method further comprises sending a first set of packets to the second device, receiving a first set of delay requests in response to the first set of packets, and sending a first set of delay responses in response to the first set of delay requests. The method further comprises, determining a first set of forward times and first set of backward times. The method further comprises, determining a first minimum forward time and a first minimum backward time. Further the method comprises determining a first correction factor.
