  • Patent number: 10970345
    Abstract: A computer-implemented method of carrying out an image-based search for information available over a network includes serving to a client computer a web page containing a set of knowledge models in response to a search request message received at a server over the network from the client computer. The knowledge models are interlinked, through a crowd-sourced schema, in a knowledgebase. The web page is structured so that graphically selecting one of the knowledge models in the web page displayed on the client computer causes display of a set of knowledge assets interlinked with the selected knowledge model.

  • Publication number: 20210096686
    Abstract: A sensor driver comprises a receiver and an interference mitigation element. The receiver is configured to acquire a resulting signal from a sensor electrode. The interference mitigation element is communicatively coupled with the receiver and is configured to receive interference data, generate an interference estimate from the interference data and a transfer function, and communicate the interference estimate to the receiver. The interference estimate removes charge from a resulting signal, mitigating effects of interference within the resulting signal.

    Abstract: A device including a transmitter, a receiver and an arbiter. The transmitter transmits a first signal. The first signal has a fundamental frequency in a first frequency band of a first wireless protocol. The receiver receives a second signal. The second signal has a fundamental frequency in a second frequency band of a second wireless protocol. The first frequency band is adjacent to or at least partially overlaps the second frequency band. The arbiter allows the transmitter to transmit the first signal in the first frequency band while the receiver receives the second signal in the second frequency band.

  • Patent number: 9277421
    Abstract: Systems, methods, and other embodiments associated with estimating noise in a receiver device based on related properties of order statistics are described. According to one embodiment, a method includes generating an initial set of magnitude squared values from a time domain impulse response of a receiver device. The method also includes generating an initial noise power estimate based on a modified set of magnitude squared values and generating a threshold value based on the initial noise power estimate. The method generates a final noise power estimate by averaging values of the initial set of magnitude squared values that are less than the threshold value and removing a thresholding bias from the resulting average.
