  • Patent number: 10394332
    Abstract: A sensor arrangement for capacitive touch and non-touch detection has a transmission electrode and a predefined number of receiving electrodes coupled with an evaluation unit. The evaluation unit operates in a non-touch detection mode and in a touch detection mode, wherein the transmission electrode generates an alternating electric near field, and in the non-touch detection mode, the evaluation unit evaluates signals from the receiving electrodes to determine non-touch gestures or a three-dimensional position of an object. In the touch detection mode a surface touch detection area defined by the predefined number of electrodes is divided into a plurality of segments wherein within each segment at least two electrodes of the predefined number of electrodes contribute with a portion of their electrode surface area such that different electrode surface area ratios are formed for each of the plurality of segments.

  • Patent number: 10048759
    Abstract: The invention refers to an input device for computer system. The invention is based on the task of creating solutions to make it possible to considerably simplify mouse-based input operations in the use of computers. This task is solved in accordance with the invention by a computer mouse with a housing and a movement detector to generate control data which as such correlate with the movement of the housing along the X or Y axis, and a hand detector to generate control data which as such correlate with the position and/or the finger gestures of a hand in relation to the housing before the computer mouse is touched. This makes it advantageously possible to carry out input operations to an even better degree with a computer mouse, in particular cursor controls, in a way that can be intuitively and easily mastered.
