  • Patent number: 10935450
    Abstract: System for verifying the proper functioning of industrial screwdrivers placed on a test bench that has a plurality of hydraulic brakes (F), with which the screwdriver is associated, suitably controlled by a hydraulic circuit comprising one pump (P), which withdraws the fluid from a reservoir (T) and provides it to a pressure regulating valve (VP), which in turn provides it to the brakes. Each brake is provided with measuring transducers (TR), connected to an electronic driver board (SP). A computer (U) communicates with such card and comprises a suitable driving program stored thereon, the driving program, once an operator has selected the brake to be used for testing the screwdriver, being able to progressively increase the braking capacity of the brakes by adjusting the pressure, until reaching a complete stop of the electronic screwdriver.

  • Patent number: 10908049
    Abstract: A method for determining an arrival-time of a rotor blade that includes attaching an RF reader to a stationary surface and an RF tag to the rotor blade. Strength-of-signal data points are collected via an RF monitoring process that includes: emitting an RF signal from the RF reader; receiving the RF signal at the RF tag and emitting a return RF signal by the RF tag in response thereto; receiving the return RF signal at the RF reader; measuring a signal strength of the return RF signal as received by the RF reader; and determining the strength-of-signal data point as being equal to the measured signal strength. The RF monitoring process is repeated until multiple strength-of-signal data points are collected. A maximum strength-of-signal is determined from the multiple strength-of-signal data points, and the arrival-time for the rotor blade is determined as being a time that corresponds to the maximum strength-of-signal.

  • Patent number: 10837941
    Abstract: An electronic control unit controls an air-fuel ratio sensor to detect an air-fuel ratio in an exhaust gas from an internal-combustion engine. An A/D converter and a sample value processor obtain a signal based on an impedance of the air-fuel ratio sensor in response to a power supply to the air-fuel ratio sensor via filters. A microcomputer determines an environment temperature of the air-fuel ratio sensor based on the signal. A switch or the microcomputer switches between an upstream side voltage supply path and a downstream side voltage supply path to obtain a signal depending on whether the air-fuel ratio sensor is operating in a low-temperature environment to improve the accuracy of the obtained signal.
