  • Patent number: 9891037
    Abstract: A tip clearance measurement system (TCMS) includes a probe and sensing circuitry. The probe directs microwave signals toward a turbine blade and receives microwave signals reflected by the turbine blade. The sensing circuitry includes a switch having a first state in which a main frequency is provided at an output of the switch and a second state in which a reference frequency is provided at an output of the switch. The sensing circuitry further includes a first conditioning circuit that receives a frequency provided at the output of the switch and provides a conditioned frequency to the probe and a second conditioning circuit that receives both the conditioned frequency provided by the first conditioning circuit and a reflected frequency received by the probe, and provides a conditioned output based on the conditioned frequency and reflected frequency.

  • Patent number: 9885627
    Abstract: Disclosed herein are methods and systems for compensating for drift that may be present in a force sensing device. In some embodiments, the force sensing device may be calibrated to compensate for the drift. The calibration may include receiving an input waveform associated with a received amount of force on the force sensing device. A system model that approximates a transfer function that provides an output waveform associated with the input waveform is then determined. Using the system model, an inverse transfer function associated with the system model is also determined. The inverse transfer function may then be applied to the output waveform which compensates for the drift.

  • Patent number: 9864895
    Abstract: The present invention relates to a method of sensing a fingerprint pattern of a finger using a fingerprint sensing device. The method comprising: controlling a group of sensing elements to change a potential of a group of sensing structures comprised in said group of sensing elements; acquiring, in response to said variation in potential, a response signal from a finger detecting circuitry indicative of the capacitive coupling between the group of sensing structures and the finger detecting structure; comparing a variation in the response signal with a predefined threshold value; and providing a signal indicating that a finger is present when the variation in response signal is greater than the threshold value. The invention also relates to a corresponding fingerprint sensing device.

  • Patent number: 9766109
    Abstract: A capacitive liquid level sensor is provided comprising a capacitive probe having a capacitance and comprising a sensing tip wherein the capacitive probe is configured such that the capacitance of the probe changes when the sensing tip is exposed to liquid. A signal generator operates to supply an electrical signal alternating between a high and low state to the capacitive probe, the electrical signal being configured such that the probe is alternately charged and discharged when the signal is high or low respectively. A comparator operates to detect the magnitude of an electrical signal across the capacitive probe and provides a first output signal value when the detected signal magnitude is greater than a predetermined threshold value and a second output signal value when the signal magnitude is less than the threshold value.

  • Patent number: 9702749
    Abstract: Disclosed are liquid surface detection methods and devices, and immunoassay analyzers. By changing the power source input of a signal drive circuit, an effective voltage of a drive signal applied by the signal drive circuit on a liquid dispensing probe is a negative voltage, so that the liquid dispensing probe is protected as the cathode in an electrolytic cell formed between the liquid dispensing probe and the cleaning fluid, and is prevented from being corroded by the cleaning fluid and rusting. Moreover, the intrinsic detection flexibility and performance of the liquid surface detection device can be ensured, and the requirements on the material and process of the liquid dispensing probe are not high, thereby effectively controlling the cost.

  • Patent number: 9672401
    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.
