  • Patent number: 11116427
    Abstract: A device for monitoring breathing activity of, e.g., athletes while exercising includes a breathing activity sensor configured to be worn by a wearer and to provide a breathing activity signal indicative of the breathing activity of the wearer. A motion sensor is configured to be worn by the wearer and to provide a motion signal indicative of the motion activity of the wearer. A processing arrangement is coupled to the breathing activity sensor to process the breathing activity signal and produce a processed breathing activity signal. The processing arrangement includes filter circuitry having a first filtering bandwidth and a second filtering bandwidth. The first filtering bandwidth is larger than the second filtering bandwidth. The filter circuitry is coupled to the motion sensor and operates with one of the first filtering bandwidth and the second filtering bandwidth selected as a function of the motion signal from the motion sensor.

  • Patent number: 9307924
    Abstract: A method of sensing an amplitude and a phase of a varying electrical signal representing an impedance of an electrically conductive tissue through which an AC stimulation current is forced may include measuring a first amplitude value of the varying electrical signal corresponding to an arbitrary initial phase offset value and assuming the first amplitude value corresponds to the amplitude and assuming the arbitrary initial phase offset value corresponds to the phase. The method may include measuring a second amplitude value of the varying electrical signal at a phase offset different from the phase. The method may further include comparing the second amplitude value with the amplitude, and updating the amplitude and the phase to correspond to one of a maximum and a minimum amplitude value and to a corresponding phase offset.
