  • Patent number: 10842464
    Abstract: Apparatus and method comprising an ultrasound transmitter, for placement at a first location on the body of a subject, to emit an ultrasound pulse; an ultrasound receiver, for placement at a second location on the body, to detect an emitted ultrasound pulse; and a controller in communication with the transmitter and receiver. The controller causes an ultrasound pulse to be emitted by the transmitter; receives a measurement signal from the receiver; determines, based on the received measurement signal, a time of arrival at the receiver, T1 s of a first part of the emitted ultrasound pulse; determines, based on the received measurement signal, a time of arrival at the receiver, T2, of a second part of the ultrasound pulse; and calculates, using T1 and T2, a flow velocity of blood in a blood vessel between the first location and the second location.

  • Patent number: 10408818
    Abstract: A gas sensor system is for use in, or in the vicinity of, a toilet, for detecting a target gas. A gas sensor detects a concentration of at least the target gas and a further, reference, gas which is received from a controlled gas release device. These concentrations are processed to obtain a concentration of the target gas relative to the concentration of the further gas by combining a change in the detected concentration of the target gas, a change in the detected concentration of the further gas, the sensitivity of the gas sensor system to the target gas and the sensitivity of the gas sensor system to the further gas. This approach avoids the need for extensive calibration operations to tune the sensor response to the environment in which it is used.
