Patent number: 6987460Abstract: Disclosed is an orientation device that may be deployed in a mechanical assembly such as a surveillance camera or enclosure to positively determine the physical orientation and/or attitude (tilt), or any change in such physical orientation and/or attitude, of either the camera or the enclosure, and report that information electronically. The invention includes a sensor that is triggered by the movement of a weighted flag along a shaft caused by gravity or gravity in conjunction with the operation of a spring. As the invention is rotated through 360°, the force of gravity and force of the spring are exerted on the weighted flag, causing it to move along the shaft as the assembly is rotated. Each movement by the flag is detected by the sensor which sends an electronic signal indicating that a predetermined point has been reached. Multiple assemblies may be used, offset from each other, to provide additional and more precise position information.Type: GrantFiled: March 14, 2003Date of Patent: January 17, 2006Assignee: PelcoInventors: Erik H. Tews, Alex Pokrovsky, Thomas C. Lyon

Patent number: 6985174Abstract: A system and method providing dynamic detection and correction of data corrupted by external interference in wireless communications network includes an interference detection unit and correction unit. Detection unit detects impact on video signals based on measuring condition of predetermined portion of video signals. Correction unit corrects the interference by selecting previously stored data to replace corrupted video data.Type: GrantFiled: October 30, 2001Date of Patent: January 10, 2006Assignee: Logitech Europe S.A.Inventors: Peter A. Thompson, Thomas C. Lyon

Publication number: 20030060218Abstract: A system and a method for the automatic tuning of wireless peripheral devices, such as wireless keyboards, mice and digital cameras by providing a host transceiver in connection with a host via a bus, the host transceiver having a plurality of antennas configured to receive and send data between a host and a peripheral device, and a host-resident software program which causes the host to select the antenna having a higher signal quality as the most productive antenna to transfer data between the host and the peripheral device. All the complexity of the antenna selection operation is achieved by a host-resident software program, which periodically measures the signal quality of each antenna, compares the signal qualities and selects the higher signal quality antenna to transfer data between the host and the peripheral device. Signal quality is assessed based on the signal level, signal-to-noise ratio or other signal quality indicators for the signal provided by the antenna.Type: ApplicationFiled: July 19, 2002Publication date: March 27, 2003Applicant: Logitech Europe S.A.Inventors: Bryed Billerbeck, Peter Thompson, Thomas C.

Patent number: 4989090Abstract: A video pixel interpolator generates interpolation pixels from incoming picture image pixels for use within a television picture scan line doubler system. The interpolator includes a temporal median filter for generating an interpolation pixel by selection of the median one of a plurality of temporal pixel samples derived from incoming video, an intra-field averager means for generating an intra-field pixel average, and a switch connected to switch an input to a line doubler of the system between outputs of the temporal median filter and the intra-field averager in response to detection of pixel motion within the picture image. Improved motion detection, and multi-channel processing are also included within the present invention.Type: GrantFiled: April 5, 1989Date of Patent: January 29, 1991Assignee: Yves C. FaroudjaInventors: Jack J. Campbell, Yves C. Faroudja, Thomas C. Lyon

Patent number: 4982280Abstract: A motion sequence pattern detector detects a periodic pattern of motion sequences within a succession of video fields, such as film mode or progressive scan mode and comprises a motion detector for detecting the presence of motion from increment to increment within predetermined increments of the succession of video fields and for thereupon putting out a first motion detection signal for each said increment, and logic circuitry responsive to the first motion detection signal for detecting the periodic pattern of motion sequences within the succession of video fields.Type: GrantFiled: July 18, 1989Date of Patent: January 1, 1991Assignee: Yves C. FaroudjaInventors: Thomas C. Lyon, Jack J. Campbell

Patent number: 4967271Abstract: A television line doubler having a video pixel interpolator and a multi-component motion detector including at least one frame-recursive component for detecting a motion value in the area of the pixel to be interpolated. A second switch switches its output to an interpolated pixel time compression circuit in accordance with the detected motion value. The second switch and the motion detector provide a proportional switch with an onset at approximately 2 to 5 IRE units of motion value and operating in accordance with the absolute amplitude of the motion value. Full switchover to the intra-field interpolator means occurring at approximately 5 to 15 IRE units of motion value amplitude. The motion detector stretches the detected motion to a predetermined number of adjacent pixel location in the line domain and a recirculation loop enables a component of motion to be recirculated.Type: GrantFiled: February 5, 1990Date of Patent: October 30, 1990Assignee: Ives C. FaroudjaInventors: Jack J. Campbell, Yves C. Faroudja, Thomas C. Lyon

Patent number: 4018990Abstract: A method and apparatus for synchronizing unrelated video type signals from two different sources without employing feedback loops between the two sources.Incoming video signals are converted from analog to digital form and are clocked into a shift register unit by input clock signals phase and frequency locked to the instantaneous horizontal frequency and the color burst frequency portions of the incoming signal. The digitized video signals progressing along the shift register are stored at the input clock signal rate in a random access (RAM) having a sufficient capacity to provide continuous output video signals during each field. The signals are clocked out from the RAM by output clock signals derived from the sync and color burst portions of a local signal comprising either composite video or composite color burst, which are synchronized with the local sync generator.Type: GrantFiled: February 13, 1975Date of Patent: April 19, 1977Assignee: Consolidated Video Systems, Inc.Inventors: Ronald D. Long, Allan L. Swain, Thomas C. Lyon
