  • Patent number: 10967138
    Abstract: A digital processor of a nebulizer controller controls and monitors drive current (I) applied to an aperture plate. The drive current is detected as a series of discrete values at each of multiple measuring points, each having a particular drive frequency The processor in real time calculates a slope or rate of change of drive current with frequency and additionally determines a minimum value for drive current leading up to the peak value. The processor uses both the value of the minimum drive current during the scan and also the maximum slope value to achieve reliable prediction of end of dose, when the aperture plate becomes dry.

  • Publication number: 20130047732
    Abstract: An arrangement for detecting toilet flushing by utilizing an acoustically-based motion detector in a simple amplifier circuit. The detector is in contact with the toilet bowl, which acts as a resonant system. Upon detection of such flushing, a subsequent event, such as a cleaning or disinfecting a toilet, ventilating the surrounding area or releasing deodorant into the area, may be triggered. The mechanically resonant system with the provided circuit is capable of separating frequencies from the frequency of the flushing water in a specific bowl design and provides a high degree of immunity to unwanted ambient frequencies. In addition, the system consumes low power and is suitable for battery power operation.

  • Publication number: 20120048022
    Abstract: The invention relates to a micromechanical sensor having at least two spring-mass damper oscillators. The micromechanical sensor has a first spring-mass-damper oscillating system with a first resonant frequency and a second spring-mass-damper oscillating system with a second resonant frequency which is lower than the first resonant frequency. The invention also relates to a method for detection and/or measurement of oscillations by means of a sensor such as this, and to a method for production of a micromechanical sensor such as this. The first and the second spring-mass-damper oscillating systems have electrodes which oscillate in a measurement direction about electrode rest positions with electrode deflections which are equal to or proportional to deflections of the spring-mass-damper oscillators.
