  • Patent number: 12259504
    Abstract: Some embodiments include an x-ray detector, comprising a housing; a sensor array disposed in the housing and configured to generate image data in response to incident x-rays; a control logic disposed in the housing; a connector interface integrated with the housing; and an adapter removably couplable to the connector interface; wherein: the control logic is configurable to operate in a plurality of operating modes; and for a first operating mode of the operating modes, the control logic is configured to process the image data and/or transmit the image data through the adapter differently than for a second operating mode of the operating modes.
    Type: Grant

  • Publication number: 20240298095
    Abstract: Embodiments include applying a first pulse to a first gate line of a plurality of gate lines of an imaging array; applying a second pulse to other gate lines of the plurality of gate lines while applying the first pulse, the second pulse having a polarity opposite to the first pulse; and sampling pixels coupled to the first gate line while applying the first pulse using sampling circuits.

  • Patent number: 10055316
    Abstract: Technology is described for generating a valid token control signal from control signals from a row driver. In one example, a matrix type integrated circuit includes a row driver module and a 2D array of cell elements. The row driver module includes a voting logic module and at least two row drivers configured to generate control signals on at least two communal lines for cell elements of a row of the 2D array. Each row driver is configured to generate control signals on at least three control lines where at least two control lines are the communal lines and coupled to a corresponding communal line of another row driver. The voting logic module is coupled to the at least three control lines of one of the row drivers and configured to generate an output based on the control signals on the at least three control lines.
