    摘要: A microelectromechanical sensor device has a detection structure and an associated electronic circuitry; the electronic circuitry receives, when the microelectromechanical sensor device is powered, an external power supply voltage and is provided with a voltage regulator which generates a regulated voltage having a different value from the external power supply voltage and at least one voltage domain powered by the regulated voltage. The electronic circuitry has a power supply management core, always powered by the external power supply voltage and controlling the voltage regulator to interrupt power supply to the voltage domain and implement a first power-down condition of the microelectromechanical sensor device.

    摘要: Provided are a sensing circuit and a sensing method thereof, a sensor chip, and a display panel. The sensing circuit includes a first transistor including a first gate and a second gate, a first capacitor, a read circuit, and a bias compensation circuit. The first gate receives a sensing signal outputted by a sensor. The first capacitor is connected between the second gate and a first fixed potential signal terminal. The read circuit is connected between the first transistor and an output terminal of the sensing circuit. The bias compensation circuit is electrically connected to the first transistor and configured to input a bias voltage into the second gate of the first transistor. The bias voltage received by the second gate reduce the threshold voltage drift of the first transistor.

    摘要: A computer implemented method, computer program product and computer system for sensor selection. The computer system can run the computer program to execute the method by dividing a two-dimensional area into cells, wherein the cells are arranged in a grid; receiving a selection trigger for a subset of cells of the grid, wherein at least one cell of the subset has at least one sensor and the at least one cell has a sampling frequency associated; determining a set of constraints for the at least one sensor; selecting the at least one sensor if the at least one sensor complies with the set of constraints; and calculating a sampling frequency of the at least one sensor dependent on the sampling frequency of the at least one cell.

    摘要: An aspect of the disclosure includes a method, a system and a computer program product. The method includes measuring a first data with a sensor, the sensor and operatively coupled computing resources having at least two power states, an operating power state and a low power state, the low power state consuming less energy than the operating power state. A first time period is determined for measuring a second data, the first time period being based at least in part on the first data. The sensor is operated, and operatively coupled computing resources at the low power state during the first time period, wherein no data measurements are acquired during the first time period. The sensor is changed to the operating power state at an expiration of the first time period.
