  • Patent number: 11119014
    Abstract: A method and apparatus for the rapid and reliable preparation of a sample for use in testing for target analytes such as bacteria, viruses, toxins and pathogenic agents in various products. A sample for testing the target analyte is collected from various sources. The method for sample preparation provides for an express process for preparing collected samples for testing. The collected sample may be concentrated by centrifugation, filtration, or other means suitable for sample concentration, homogenized with the addition of a broth and enriched for specified period of time. Immunomagnetic separation of the sample occurs with receptor-coated magnetic microspheres in different test-specific formulations (singleplex or multiplex). An automatic testing system is disclosed which includes a biological testing cassette, in which testing of the sample occurs using liquid crystal diagnostic methodologies.

  • Patent number: 10841494
    Abstract: Video image stabilization provides better performance on a generic platform for computing devices by evaluating available multimedia digital signal processing components, and selecting the available components to utilize according to a hierarchy structure for video stabilization performance for processing parts of the video stabilization. The video stabilization has improved motion vector estimation that employs refinement motion vector searching according to a pyramid block structure relationship starting from a downsampled resolution version of the video frames. The video stabilization also improves global motion transform estimation by performing a random sample consensus approach for processing the local motion vectors, and selection criteria for motion vector reliability. The video stabilization achieves the removal of hand shakiness smoothly by real-time one-pass or off-line two-pass temporal smoothing with error detection and correction.

  • Patent number: 10637784
    Abstract: Technologies are described for performing equation-based rate control using delay. For example, an observed network data rate and a network delay can be obtained for a network communication. A target network data rate can be calculated using the observed network data rate and the network delay. The target network data rate is calculated using an equation-based approach. For example, the equation-based rate control can set the target network data rate to a value that is directly proportional to the observed network data rate and inversely related to the network delay. The target network data rate is used to set the bitrate for the network communication.

  • Patent number: 10129155
    Abstract: Technologies are described for performing hybrid rate control that switches between a delay-based mode and a passive loss-based mode for a flow of network traffic. The switching can be performed based on the presence of loss-based TCP network flows. For example, rate control can be performed for a flow of network traffic in a delay-based mode. When the presence of a loss-based TCP network flow is detected, the flow of network traffic can be switched from the delay-based mode to a passive loss-based mode and rate control can be performed in the passive loss-based mode. When the loss-based TCP flow is no longer detected, the flow of network traffic can be switched back to the delay-based mode.

  • Publication number: 20180145780
    Abstract: Technologies are described for determining clock offsets between computing devices. Clock offsets between the computing devices are determined based on timestamp information associated with forward packets and reverse packets sent between the computing devices. For example, a forward series and a reverse series of timestamp points can be obtained from forward and reverse network packets. A forward anchor series and a reverse anchor series can be generated from the forward series and the reverse series. The clock offset between the computing devices can be estimated using the forward anchor series and the reverse anchor series.
