In order to identify imbalance in the machine, a spectral energy of the machine can be calculated based on the changes in the clearance distances, and the imbalance in the machine can be identified based on the spectral energy. The system and method can determine a trigger speed of the machine that is associated with the wear in the machine based on the changes in the clearance distance. A remaining useful life of the machine can be estimated based on changes in the trigger speed.

  • Patent number: 9517468
    Abstract: Disclosed are methods to aid in a calibration of a vertical orientation of a nozzle tip to a sample container in a processing or testing system. The method includes positioning the nozzle over a calibration target at a home height location (HM), moving the nozzle downward a distance (D) until contact with the calibration target is sensed, positioning the nozzle over the sample rack and moving the nozzle downward until contact with a registration location is sensed, imaging the sample rack and calibration target to determine a height (H) between the registration location and calibration target, and calculating a translation ratio (TR) between the height (H) measured in pixel space and the distance (D) measured in machine space. The translation ratio (TR) may be used to drive the nozzle tip to a predetermined depth. A robot calibration system is disclosed, as are other aspects.

  • Patent number: 9383876
    Abstract: A fingerprint sensing system comprises a sensor array with a plurality of sensing structures and read-out circuitry connectable to each of the sensing structures, and power supply circuitry arranged to provide to the read-out circuitry a substantially constant supply voltage being a difference between a high potential and a low potential. The fingerprint sensing system is configured in such a way that the low potential and the high potential are variable while substantially maintaining the supply voltage, and the read-out circuitry is connectable to each of the sensing structures in such a way that a variation in the low potential and the high potential while substantially maintaining the supply voltage results in a change of the charge carried by a sensing structure connected to the read-out circuitry. The change in charge is indicative of a capacitive coupling between the sensing structure and the finger.
