  • Patent number: 10425079
    Abstract: Improved driven shield electrodes used with capacitance sensors are described in this application. Typical capacitance sensors suffer from parasitic capacitance that can make proximity sensing difficult. The driven shield described herein is divided into multiple portions and an increased drive voltage is applied to at least one of these portions. This increase voltage enhances the electric field of the capacitance sensor and increases the proximity sensitivity. Other embodiments are described.

  • Patent number: 10335056
    Abstract: A sensor for electrically measuring a force distributed unevenly across a measurement surface of the sensor includes a spring device between a measurement surface and a counter-surface. A first measuring element is arranged in or on the measurement surface and a second measuring element is arranged in or on the counter-surface, the elements substantially completely covering these surfaces in each case. The measuring elements include capacitor plates, and are designed such that the measuring signal can be generated from a distance between the measuring elements. The spring device has a large number of elastically designed spring members which are arranged spaced apart from each other by gaps so that each spring member upon loading by the force can deform into the gaps. This arrangement makes it is possible to measure unevenly distributed forces between bodies which may be of very different forms.
