  • Patent number: 9815343
    Abstract: A method for tire sensing includes providing a tire comprising (a) a tire body having an outer wall for contact with a surface and opposite side walls, and an inside surface and (b) at least one flexible strain gauge positioned along the inside surface of the tire body, wherein the at least one flexible strain gauge is positioned to sense tire deflections or strain. The method further includes sensing tire data indicate of the tire deflections using the at least one flexible strain gauge and communicating the tire data to a data acquisition system, control system, or computer system. The flexible strain gauge(s) may be soft dielectric capacitive sensors, soft resistive sensors, or soft capacitive/resistive sensors.

  • Patent number: 7587647
    Abstract: A method of testing an analog and/or mixed-signal circuit can be used in either a production or a built-in self test environment. The method includes generating an excitation signal for testing by using dynamic element matching for performance enhancement of the test signal generator that applies an excitation, and/or by measuring an output of the DUT using dynamic element matching for performance enhancement of an output measurement device. Signal generators and circuits using aspects of the method are also discussed.

  • Patent number: 5327129
    Abstract: A method and apparatus for a system physically realizing a transfer function and having improved accuracy and fast calibration is described, comprising a plurality of stages configured in a serial fashion, each stage having a transfer function realized with fixed and adjustable elements. Control logic for selectively reconfiguring said stages, operable for coupling any one of said stages to a reference signal and for further coupling said one of said stages to the remaining ones of said stages in a serial fashion is added; control logic for selectively causing said stages to transmit at their output responses to an input which enable measurement of individual components within said stages is included; and control logic for updating the adjustable elements within each stage is described.
