Patent number: 11800056Abstract: Embodiments of the disclosure generally relate to video-conferencing systems, and more particularly, to advanced camera devices with integrated background differentiation capabilities, such as background removal, background replacement, and/or background blur capabilities, which are suitable for use in a video-conferencing application. Generally, the camera devices described herein use a combination of integrated hardware and software to differentiate between the desired portion of a video stream and the undesired portion of the video stream to-be-replaced. The background differentiation and/or background replacement methods disclosed herein are generally performed, using a camera device, before encoding the video stream for transmission of the video stream therefrom.Type: GrantFiled: February 11, 2021Date of Patent: October 24, 2023Assignee: Logitech Europe S.A.Inventors: Joseph Yao-Hua Chu, Ting Chia Hsu, Jeffrey Phillip Fisher

Patent number: 11800048Abstract: Embodiments of the disclosure provided herein generally relate to methods and video system components that have integrated background differentiation capabilities that allow for background replacement and/or background modification. In some embodiments, undesired portions of video data generated in a video environment are separated from desired portions of the video data by taking advantage of the illumination and decay of the intensity of electromagnetic radiation, provided from an illuminator, over a distance. Due to the decay of intensity with distance, the electromagnetic radiation reflected from the undesired background has a lower intensity when received by the sensor than the electromagnetic radiation reflected from the desired foreground. The difference in the detected intensity at the one or more wavelengths can then be used to separate and/or modify the undesired background from the desired foreground for use in a video feed.Type: GrantFiled: February 24, 2021Date of Patent: October 24, 2023Assignee: Logitech Europe S.A.Inventors: Joseph Yao-Hua Chu, Jeffrey Phillip Fisher, Ting Chia Hsu

Publication number: 20180131362Abstract: In accordance with aspects of the present invention, a power control circuit includes a MAIN window comparator circuit providing a MAIN signal; an AUX window comparator circuit providing an AUX signal; a state machine receiving the MAIN signal and the AUX signal; a MAIN slew circuit coupled to drive a MAIN switch, the MAIN switch coupled between MAIN and an output; an AUX slew circuit coupled to drive an AUX switch, the AUX switch coupled between AUX and the output; wherein the state machine operates to continuously activate either the MAIN switch or the AUX switch according to the MAIN signal and the AUX signal such that the output is continuously coupled to either a MAIN input or an AUX input with minimum disruption to output voltage, input and output capacitance inrush currents or reverse conduction. What really makes the circuit unique is it is combined with an adjustable forward biased rectification circuit for each channel of MAIN and AUX.Type: ApplicationFiled: July 6, 2017Publication date: May 10, 2018Inventors: Roger BEESTON, David F.

Publication number: 20060125074Abstract: A method of connecting internal silver traces to external gold to produce a gold external side metal for a low-temperature co-fired ceramic package includes the deposition of a ruthenium dioxide cermet barrier layer between layers of gold and silver. An LTCC package constructed in accord with the inventive method has gold, ruthenium and silver layers that are parallel to the LTCC package surface and normal to and also electrically coupled to a conductive trace formed within the LTCC layers of the package.Type: ApplicationFiled: December 15, 2004Publication date: June 15, 2006Inventors: Phillip Fisher, James Elsner, Dean Marshall
