John F Cvetko, Ying K Kwong, James F Sandau: Interactive multimedia system. Tektronix, Francis I Gray, June 11, 2002: US06404811 (449 worldwide citation)

An interactive multimedia audio/video communications system uses a lower data rate, non-deterministic graphics/command network having a plurality of desktop viewing stations and a network server. A separate, higher data rate, deterministic audio/video network is coupled to the plurality of desktop v ...

William J O Grady, Robert J Dubner: Embedment of data in a video signal. Dubner Computer Systems, Francis I Gray, November 6, 1990: US04969041 (281 worldwide citation)

Data is embedded in a video signal by adding a low level wavefrom to the video signal, the low level wave form having a level below the noise level of the video signal and corresponding to the data. To detect the data embedded in the video signal the video signal is correlated with the low level wav ...

Bruce L Rayner: Video editing system operator inter-face for visualization and interactive control of video material. The Grass Valley Group, John Smith Hill, Francis I Gray, February 7, 1995: US05388197 (257 worldwide citation)

An operator interface for a video editing system provides a visual sense of the content of video sequences, as well as their length, while also providing enhanced interactive control of locations and time alignments of the video. As the video sequence is processed into the system, a small but repres ...

Eugene F Lynch, Guy W Cherry, Mayer D Schwartz: Time warping for video viewing. Tektronix, Francis I Gray, John Smith Hill, John D Winkelman, August 1, 1995: US05438423 (248 worldwide citation)

Time warping for video viewing is achieved by providing a random access dynamic buffer for a video signal from a selected video channel. The video signal is continuously written into the dynamic buffer in a recirculating fashion, and may be read out on a random access basis so that the viewer may co ...

David D Stubbs, Mark P Barnett, William A Greenseth: Method of generating instruction sequences for controlling data flow processes. Tektronix, Alexander C Johnson, Micah D Stolowitz, Francis I Gray, August 4, 1992: US05136705 (208 worldwide citation)

Computer-controlled test and measurement systems, including resources having multiple states and resources having multiple inputs, are modeled as data flow diagrams of topologically interconnected resources. A set of "tasks" are defined for changing the states of multiple-state resources and causing ...

Geoffrey C Herrick: Method of securing metallic members together. Tektronix, Francis I Gray, March 1, 1988: US04727633 (177 worldwide citation)

Two metallic members are connected together over a defined area of respective surfaces of the members by providing at least one layer of metal on at least one of the surfaces. The or each layer of metal has at least one elementary component and is of essentially uniform composition over the defined ...

Bruce L Rayner: Video editing operator interface for aligning timelines. The Grass Valley Group, Francis I Gray, May 21, 1996: US05519828 (153 worldwide citation)

An operator interface for a video editing system provides a visual sense of the content of video sequences, as well as their length, while also providing enhanced interactive control of locations and time alignments of the video. As the video sequence is processed into the system, a small but repres ...

Keith R Slavin, Donald Craig: Touch controlled zoom of waveform displays. Tektronix, Francis I Gray, July 5, 1988: US04755811 (152 worldwide citation)

Touch controlled zoom of a waveform display uses a touch screen for the display surface. Function buttons for moving or expanding the waveform display and for determining the axis of such movement or expansion operate in conjunction with a rotary encoder. Expansion, or zoom, is accomplished by conta ...

Einar O Traa: Adaptive power supply for avalanche photodiode. Tektronix, Francis I Gray, April 24, 2001: US06222660 (124 worldwide citation)

An adaptive power supply for an avalanche photodiode (APD) is used to determine an optimum bias voltage. Without an optical signal input the adaptive power supply applies a swept voltage to the APD while monitoring the photodiode current. When breakdown occurs, the voltage is noted and the bias volt ...
