    Abstract: A method and system is disclosed for determining an optimum drive signal for an acoustic transducer. A pulse signal is employed as a wideband reference signal Vr(t); and, in a pulse-echo measurement a corresponding wideband echo signal Ve(t) is obtained. A normalized loop frequency response {circumflex over (X)}(f) for the acoustic transducer is defined as a ratio of a Fourier Transform of the Ve(t) to a Fourier Transform of the Vr(t), and a normalized loop time response X(t) is defined as an Inverse Fourier Transform of the {circumflex over (X)}(f). An optimum drive signal B(t) for the acoustic transducer is defined as B(t)?*G(t), wherein a coefficient ? is determined to multiply a function G(t), in which the function G(t) is derived from one of the normalized loop time response X(t) and the normalized loop frequency response {circumflex over (X)}(f).

  • Patent number: 10466066
    Abstract: Techniques of altitude determination by user equipment (UE) in a mobile communications network are discussed. A request for calibration data is transmitted to a node of the network. Barometric calibration data is received at the UE. A barometric pressure sensor in the UE measures a barometric pressure value based on the barometric calibration data. Measuring the barometric pressure value using the barometric pressure sensor in an embodiment comprises adjusting a measured barometric pressure value that is measured using the barometric pressure sensor. The barometric pressure value is transmitted to the node. The UE receives a second part of the barometric calibration data, and in dependence of the second part of the barometric calibration data and/or in dependence of the measured barometric pressure value, determines an altitude of the user equipment.

  • Patent number: 10451597
    Abstract: A determination device determining malfunction of a humidity sensor includes a malfunction determination portion. The humidity sensor includes a humidity detector, a temperature detector and a heater. The humidity detector has a humidity-sensitive film in an intake passage and detects a relative humidity of intake air taken into an internal combustion engine for a vehicle. The temperature detector detects a temperature of the humidity-sensitive film. The heater heats the humidity-sensitive film and the temperature of the humidity-sensitive film is increased by the heater. The malfunction determination portion estimates an estimated relative humidity at a subsequent temperature from an original relative humidity and the subsequent temperature, and compares the estimated relative humidity at the subsequent temperature and an actual subsequent relative humidity to determine malfunction of the humidity detector.
