  • Patent number: 11067519
    Abstract: A strain detecting device includes a sensor portion and a covering elastic deformation member. The elastic deformation member generates heat when compressed and absorbs heat when expanded, resulting in heat flux. The sensor portion includes first and second heat flux sensors, each of which has first and second sensor surfaces formed opposite to each other. Each sensor outputs a strain-indicating signal of a polarity when the heat flux passes through the sensor, from the first sensor surface to the second sensor surface, and outputs a strain-indicating signal of an opposite polarity when the heat flux passes through the sensor in reverse, from the second sensor surface to the first sensor surface. The first sensor surfaces are opposed to each other across a heat absorbing member interposed between the sensors. The sensor portion generates signals based on the heat flux generated by deformation of the elastic deformation member.

  • Patent number: 11065399
    Abstract: A nebulizer has an aperture plate, a mounting, an actuator, and an aperture plate drive circuit (2-4). A controller measures an electrical drive parameter at each of a plurality of measuring points, each measuring point having a drive frequency; and based on the values of the parameter at the measuring points makes a determination of optimum drive frequency and also an end-of-dose prediction. The controller performs a short scan at regular sub-second intervals at which drive current is measured at two measuring points with different drive frequencies. According to drive parameter measurements at these points the controller determines if a full scan sweeping across a larger number of measuring points should be performed. The full scan provides the optimum drive frequency for the device and also an end of dose indication.

  • Patent number: 11054326
    Abstract: In a physical quantity sensor, a first substrate has a recess depressed from a second surface to provide a thin film section adjacent to a first surface, and a second substrate has a first surface bonded to the first surface of the first substrate, and has a hollow depressed from the first surface and facing the recess. The recess and the hollow have such sizes that a projected line defined by projecting an end of a bottom surface in the recess to the first surface of the first substrate surrounds an open end of the hollow. When the thin film section is displaced toward the hollow, a maximum tensile stress is generated at a position on a rear surface of the thin film section intersecting an extended line along a normal direction to the first surface of the first substrate and passing through the open end of the hollow.

  • Patent number: 11054339
    Abstract: A machine bearing disposed on a rotatable member, such as may be present on a vehicle, is described. A method for monitoring a state of health of the machine bearing includes monitoring, via a microphone, an acoustic signal, and coincidently determining a rotational speed of the rotatable member associated with the machine bearing. The sound spectrum is correlated to the rotational speed of the rotating member, and a time-frequency analysis is executed to determine a sound spectrum. The sound spectrum is transformed to a residual spectrum. A first feature associated with a first frequency band and a second feature associated with a second frequency band are extracted from the residual spectrum. The state of health associated with the machine bearing is detected based upon the first and second features, and is communicated to a second controller.

  • Patent number: 11047686
    Abstract: In a digital gyroscope, the rate signal (including the quadrature) and the displacement signal of the drive part are sampled with an ADC. This displacement signal has the same frequency and phase as the quadrature signal that gets sampled in the rate channels. The displacement signal is sampled with the same clock as the rate signal resulting in the displacement signal having the same close-in phase noise folded into the signal band as the sampled quadrature in the rate signal. The sampled drive signal is subtracted from the sampled rate signal to eliminate the clock jitter induced noise in the rate signal. This relaxes the close-in phase noise requirement of the PLL and allows for a low power PLL implementation.

A laser beam is directed to fall onto the nanomembrane over the sample, while a radiation sensor is operated to detect photoluminescent radiation emitted by the nanomembrane in response to the laser beam. A spectral shift in the detected photoluminescent radiation emitted by the nanomembrane is determined, and thermal diffusivity/conductivity is calculated from the determined spectral shift of the photoluminescence.

  • Patent number: 11041764
    Abstract: A sensor system for detecting events is provided. The sensor system includes a sensor and a read-out interface. The sensor includes a transducer and a memory device. The transducer detects an event and generates a sensor signal in response to the event. The memory device includes a floating-gate with a sensing interface coupled to the transducer. The sensing interface has an energy barrier that leaks electrons at a predetermined electron leakage rate through Fowler-Nordheim (F-N) tunneling. The sensor signal alters a geometry of the energy barrier to change the electron leakage rate. The read-out interface is communicatively coupled to the memory device and retrieves data stored on the memory device for analysis. The event and a timestamp of the event are identifiable from the stored data.
