摘要： The touch panel module comprises a touch panel sensor element and a touch panel controller for measuring changes in capacitance associated with one or more sensor electrodes comprising the touch panel sensor element and generating corresponding touch panel output signalling is communicated to the host controller. The capacitance measurement circuit comprises a capacitance measurement channel coupled to a power supply line for the touch panel module, e.g., a ground for the touch panel module, and is configured to measure a capacitance associated with the touch panel module circuitry coupled to this power supply line and to generate corresponding capacitance measurement circuit output signalling for communication to the host controller. The touch panel power supply at the touch panel module is galvanically isolated from the capacitance measurement circuit power supply at the capacitance measurement circuit. Thus, the touch panel module may operate in a broadly conventional manner, whilst the capacitance measurement circuit simultaneously, or in a time multiplexed manner, measures a capacitance associated with the overall circuitry of the touch panel module, thereby providing a relatively sensitive proximity sensor.

摘要： A touch-sensitive position sensor comprises an array of sensing nodes defined by electrodes arranged in columns across a sensing surface and a plurality of traces arranged to provide electrical connections from the respective sensing nodes to a perimeter of the sensing surface. The traces for the sensing nodes in a particular column run between the column and a neighbouring column on one or other side of the column. For at least a subset of the columns the number of traces for the sensing nodes in a particular column which run to one side of the column and the number of traces for the sensing nodes in the given column which run to the other side of the given column are different for different columns.

摘要： Disclosed a sensing apparatus having a frame element and a displaceable element mounted relative to the frame element. The sensing apparatus comprises a plurality of displacement sensor elements each configured to provide a displacement sensor output signal indicative of a displacement between the frame element and the displaceable element, wherein the plurality of displacement sensor elements are arranged at different spatial locations relative to the displaceable element and configured to provide a displacement sensor output signal indicative of a displacement between the frame element and the displaceable element at the respective spatial location. The sensing apparatus further comprises processing circuitry configured to obtain the displacement sensor output signals from the plurality of displacement sensor elements and determine whether displacement of the displaceable element is a valid displacement by comparing at least the ratio between the displacement sensor output signals to one or more expected ratios vance.

摘要： A displacement sensor for sensing a change in separation between a first element and a second element along a displacement direction. The sensor comprises a reference electrode mounted to the second element in the form of a conductive trace on a surface of the second element facing the first element. A deformable electrode, e.g. a conductive elastomeric material, is arranged between the first element and the second element so as to overlie the reference electrode. The deformable electrode has a contact surface facing the reference electrode and insulated therefrom. At least part of the contact surface is inclined relative to an opposing surface of the reference electrode such that when the deformable electrode is compressed along the displacement direction there is a reduction in volume between the contact surface and the opposing surface of the reference electrode, thereby changing the capacitive coupling between them. The sensor further comprises a controller element configured to measure a characteristic of the capacitive coupling between the reference electrode and the deformable electrode and to determine if a change in separation between the first element and the second element has occurred be determining if there is a change in the characteristic of capacitive coupling between the reference electrode and the deformable electrode.
