  • Patent number: 11948401
    Abstract: Various embodiments of devices, systems, and methods for providing AI-based physical function assessment recordings and assessment performance analytics for a subject are described. A series of video frames are obtained that include the subject. Computer vision techniques that use artificial neural networks may be applied to the video frames to: detect a Person of Interest (POI) and an Object of Interest (OOI) in the video frames; track movement of the POI and the location of the OOI in subsequent video frames; detect body key points; and detect postures and posture transitions of the POI. Physical function indicators may be calculated and function analytics provided based on the assessment.

  • Patent number: 11477328
    Abstract: PTP timestamps are obtained and correlated to internal audio time and timestamps. This allows Ethernet/IP audio devices to be closely aligned with local digital audio devices to allow improved AEC operations. By performing repetitive PTP timestamps based on local audio time, drift between PTP time and local audio time is determined and corrected. By performing the PTP to local audio time operations on each independent Ethernet network, the Ethernet/IP audio devices can be split between independent LANs. If some local digital audio inputs formed from analog inputs are not aligned with other local digital audio inputs, signals can be provided in analog format and audio samples of the signals can be correlated to local audio time. With correlations performed as necessary based on the various audio inputs in use, high quality AEC operations are performed.

  • Patent number: 10939045
    Abstract: A videoconference apparatus and method coordinates a stationary view obtained with a stationary camera to an adjustable view obtained with an adjustable camera. The stationary camera can be a web camera, while the adjustable camera can be a pan-tilt-zoom camera. As the stationary camera obtains video, participants are detected and localized by establishing a static perimeter around a participant in which no motion is detected. Thereafter, if no motion is detected in the perimeter, any personage objects such as head, face, or shoulders which are detected in the region bounded by the perimeter are determined to correspond to the participant.

  • Publication number: 20190389964
    Abstract: Disclosed herein are humanized anti-LGR5 antibodies for the treatment of cancer. Antibodies disclosed herein may bind LGR5 without disrupting LGR5-RSPO1 binding or signaling, and may disrupt LGR5 signaling through Wnt that is independent of RSPO1. Also disclosed are heavy and light chain polypeptide sequences for the biding of LGR5, for example without disrupting LGR5-RSPO binding or signaling.

  • Patent number: 10491809
    Abstract: A system for ensuring that the best available view of a person's face is included in a video stream when the person's face is being captured by multiple cameras at multiple angles at a first endpoint. The system uses one or more microphone arrays to capture direct-reverberant ratio information corresponding to the views, and determines which view most closely matches a view of the person looking directly at the camera, thereby improving the experience for viewers at a second endpoint.

  • Patent number: 10490202
    Abstract: A videoconference apparatus at a first location detects audio from a location and determines whether the sound should be included in an audio-video stream sent to a second location, or excluded as an interfering noise. Determining whether to include the audio involves using a face detector to see if there is a face at the source of the sound. If a face is present, the audio data from the location will be transmitted to the second location. If a face is not present, additional motion checks are performed to determine whether the sound corresponds to a person talking, (such as a presenter at a meeting), or whether the sound is instead unwanted noise.

  • Publication number: 20190013868
    Abstract: A method and apparatus for transporting multiple low-speed data streams across a high-speed communication channel or link. In one embodiment of the method, first and second data streams are transmitted at first and second data transmission rates, respectively, via an optical cable, wherein the first and second data transmission rates are distinct. Components of the first data stream are transmitted via the optical cable between transmission of components of the second data stream via the optical cable, and components of the second data stream are transmitted via the optical cable between transmission of components of the first data stream via the optical cable.
