Patent number: 9258494Abstract: Systems and methods disclosed herein include preventing use of a Focal Plane Array (“FPA”) in a thermal imaging system if used in conjunction with a weapons-related activity by disabling the FPA in response to detecting one or more shock pulse events using accelerometers coupled with the thermal imaging system. The method includes monitoring an output from the one or more of the accelerometers to determine whether a shock pulse acceleration event has been detected that exceeds a predetermined threshold. The method also includes determining that a second acceleration event associated with the accelerometers exceeds a second predetermined threshold. The method further includes disabling the thermal imaging system in response to the detected acceleration events.Type: GrantFiled: March 21, 2013Date of Patent: February 9, 2016Assignee: DRS Network & Imaging Systems, LLCInventors: John A.

Publication number: 20070189399Abstract: The present invention provides a method and apparatus for synchronizing wireless video data. The method involves first synchronizing the pixel clock of a video output device with the pixel clock of a video input device. This is accomplished by latching video counters in the input and output devices (creating a transmit and receive timestamp) for each wireless video data packet and adjusting the pixel clock frequency of the output device according to differences between these timestamps. Once the pixel clocks are synchronized, video frames from the video output device are synchronized with video frames from video input device such that only a fraction of a video frame is buffered at any time. The video frames are synchronized by offsetting the data stream from the video input device N lines ahead of the data stream from the video output device, wherein N is less than the total number of lines in a single video frame.Type: ApplicationFiled: February 10, 2006Publication date: August 16, 2007Inventors: Gregory Christison, Fred Stivers, Felix Fernandes

Publication number: 20070188481Abstract: The present invention provides a method and apparatus for optimizing the transmission of video configuration data in a system comprising a host computer and a display monitor. The invention comprises a wireless video source adapter connected to the host computer and a wireless video sink adapter connected to the monitor. Upon system startup, the video sink adapter acquires EDID information from the monitor and transmits it to the video source adapter, which does not activate its connection and indicate its presence to the host computer until after receiving the EDID information. The video source adapter then supplies the EDID information to the host computer in response to EDID requests from the computer. In this manner, the video source adapter acts as a virtual proxy for the display monitor from the point of the view of the host computer. The host computer then uses the EDID information to configure its video signal to match the parameters of the display monitor.Type: ApplicationFiled: February 10, 2006Publication date: August 16, 2007Inventors: Gregory Christison, Brian Doherty, John Sarallo, Sidney Schrum

Publication number: 20060222132Abstract: A novel receive timing manager is presented. The preferred embodiment of the present invention comprises an edge detection logic to detect the data transition points, a plurality of data flip-flops for storing data at different sample points, and a multiplexer to select the ideal sample point based on the transition points found. A sample window is made with multiple samples. The sample window size can be designed smaller or greater than the system clock period based on the data transfer speed and accuracy requirement.Type: ApplicationFiled: April 4, 2005Publication date: October 5, 2006Inventors: Denis Beaudoin, Ritesh Sojitra, Gregory Christison

Publication number: 20060153291Abstract: The present invention provides a method and apparatus for compressing video data for wireless transmission. The invention continually monitors the output of a video data encoder and maintains a running average for the data output rate over multiple lines of video data. The encoder compresses video data on a line-by-line basis. The invention also monitors the occupancy of the data buffer and as well as the performance of the wireless subsystem to determine real time available channel capacity. If the average data rate exceeds the available channel capacity, the invention increases data compression on subsequent lines of video data until the average data rate falls within the channel capacity. If the average data output rate is less than the channel capacity, the invention reduces data compression on subsequent lines of video data until the average data rate increases to match the channel capacity.Type: ApplicationFiled: January 9, 2006Publication date: July 13, 2006Inventor: Gregory Christison
