A displacement sensor comprising: a reference electrode; and a displacement element movably mounted relative to the reference electrode and comprising a substrate having first and second opposing surfaces with a first electrode arranged around a peripheral part of the first surface and a second electrode arranged around a peripheral part of the second surface, and wherein the reference electrode on the same side of the substrate as the second electrode and offset therefrom; and a controller element configured to measure a capacitance characteristic of the second electrode at different times and to determine whether there has been a displacement of the displacement element relative to the reference electrode based on whether there has been a change in the capacitance characteristic of the second electrode.

The switch housing for capacitive switches has an outer contact surface and flat electrode structures which are arranged on the inside and in a position opposite the contact surface and which are placed by two-component injection molding in recessed regions of the housing body injected from a first, electrically non-conductive plastic component by a second, electrically conductive plastic component. Preferably, both plastic components are a polycarbonate, the second plastic component containing carbon fibers.

In a touch sensor unit, since a base portion is provided with a hard resin portion for holding a curved state of a sensor portion deformed in conformity to a curved shape of a door frame of a tail gate, even when the base portion is not fixed to the tail gate, it is possible to hold the curved state of the base portion. Therefore, after the curved base portion is fixed to the tail gate with a double-sided adhesive tape, even if the double-sided adhesive tape is degraded with age, a restoring force of the sensor portion does not remove the double-sided adhesive tape.

A key structure includes, from top to bottom in sequence: at least one key main body, made of light transmissible material; a key frame, adapted to mount the key main body; an elastic supporting portion, allowing the key main bodies to move back and forth vertically; at least one bump, formed on one side of the elastic supporting portion; a detection module, sensing the action of the key main body and allowing the bump to be in touch therewith selectively; and a display screen, configured on one side of the detection module. A user can see the bottom display screen through the key main body directly, and the elastic supporting portion drives the bumps to move downward to touch the detection module after the user presses the key main body down. Whereby, the applicable range of the present invention is increased by changing the contents of the display screen.

An electronic sensor module for a handle may have one sensor unit having a movable sensor element and a fixed sensor element which is arranged spaced apart from and opposite the movable sensor element. The module may also have an electronics unit which is electrically connected to the sensor elements for triggering a switching signal and on which the fixed sensor element is arranged. At least the movable sensor element may be encapsulated at least in some regions by a foam material and is designed as an integrated component in the form of a preassembly unit. Connection elements of the movable sensor element protrude from the foam material in a preassembly state and are connected to the electronics unit in an assembled state. A handle module and to a movable vehicle element are also described.

An outside door handle module for a vehicle may have one handle element having a handle outer side and a handle inner side. The module may also have one gesture sensor and an actuation sensor. The gesture sensor may be arranged on or in the handle outer side and the actuation sensor may be arranged on or in the handle inner side.

The present disclosure relates to an input device and a method of producing the device. The input device includes a flat panel defining an array of control surfaces, a support disposed on a side of the panel facing away from an operator, and a flat film layer structure disposed between the flat panel and the support which defines an array of capacitive sensors; wherein each capacitive sensor forms a measuring capacitance assigned to one of the control surfaces; wherein the support forms at least one web, which protrudes towards the flat panel and connects to the flat panel to fix the film layer structure between the flat panel and the support.

A capacitive multipath force sensor module includes a movable actuator, first and second stationary capacitor plates, and a central capacitor plate connected to the actuator and positioned between the stationary plates. The central plate moves by a same amount toward one stationary plate and away from the other stationary plate when the actuator is moved. In multiple successive cycles, while the first stationary plate is held at ground, (i) the central plate and the second stationary plate are connected to a voltage and (ii) are then disconnected from the voltage with the central plate being connected to a capacitor having a known capacitance value to thereby enable a charge quantity stored on the central plate to be transferred to the capacitor. After a predefined number of cycles, a voltage of the capacitor, which is indicative of an amount of movement of the actuator, is measured.
