Abstract:
A key for user input having superior tactile qualities. The key is suspended by a magnetic field force to improve the smoothness of motion. Two compact interleaved members link a keycap to a key base to provide highly precise parallel travel with reduced tilt and flexion, and improved durability.
Abstract:
Eine berührungs- und/oder annäherungsempfindliche Eingabevorrichtung weist eine Abdeckplatte (14) mit wenigstens einem zumindest teilweise lichtdurchlässigen Bedienabschnitt (14b), wobei der Bedienabschnitt (14b) einem Benutzer der Eingabevorrichtung zugewandt ist und ein Bedienfeld für den Benutzer bildet; eine zumindest teilweise lichtdurchlässige Sensorfolie (16) mit wenigstens einem kapazitiven Sensorfeld (18); und eine Trägerplatte (26), auf welcher wenigstens ein Leuchtmittel (28) angeordnet ist, auf. Die Eingabevorrichtung weist ferner eine zumindest teilweise lichtdurchlässige Dekorfolie (22) mit wenigstens einem Dekorelement (23) auf, welche als separates Bauteil zur Sensorfolie (16) ausgestaltet ist, sodass die Dekorfolie unabhängig von der Sensorfolie hergestellt und auf diese Weise einfach an gewünschte Varianten der Eingabevorrichtung angepasst werden kann. Die Trägerplatte (26), die Dekorfolie (22), die Sensorfolie (16) und die Abdeckplatte (14) sind derart hintereinander angeordnet, dass das von dem Leuchtmittel (28) ausgesendete Licht die Dekorfolie (22), die Sensorfolie (16) und den Bedienabschnitt (14b) der Abdeckplatte (14) durchläuft.
Abstract:
Systems for detecting an amount and/or location of a force applied to a device using a piezoelectric film are provided. One example system can include a transparent piezoelectric film (608) for generating an electric charge in response to a deformation of the film. Electrodes (606, 610) positioned on opposite surfaces of the piezoelectric film can be used to detect the generated electric charge and determine an amount and/or location of force applied to the film based on the generated electric charge. In another embodiment, the system can include a capacitive touch sensor for determining a location of a touch event on the device.
Abstract:
The application provides a capacitive button arrangement for a faceplate of an automobile. The capacitive button arrangement includes a guided plate unit and an evaluation unit. The guided plate unit comprises at least two capacitive buttons. Each capacitive button includes a capacitive sensor for transmitting a primary detection signal. The guided plate unit comprises a guided plate for transmitting a secondary detection signal. The evaluation unit is electrically connected to the capacitive sensors of the capacitive buttons for receiving the primary detection signals from the capacitive sensors and is electrically connected to the guided plate for receiving the secondary detection signal.
Abstract:
The invention relates to a control unit for electrical apparatus, of the type comprising a control device which may be wall-mounted and an actuation plate which may be secured thereto. The actuation plate comprises a cover surface and a sensor member for detecting when a user's finger comes into contact. The control device comprises a base structure, a terminal block for the electrical connection of the control unit to the electrical apparatus and an abutment member comprising an edge designed to abut on an inner surface of said actuation plate opposite said cover surface, said abutment member being connected to said base structure in such a way as to enable the edge at least to move in translation in a fastening direction of said actuation plate on said control device.
Abstract:
A keyboard includes a bezel having a plurality of key openings and a plurality of key holding features configured adjacent to the plurality of key openings on a bottom side of the bezel. A plurality of keycaps are positioned within the plurality of key openings. A chassis is included that has a plurality of planar-translation effecting mechanisms each supporting a respective one of the plurality of keycaps to guide the respective keycap in a press direction and a second direction as the keycap moves from the unpressed position toward the pressed position. The keypad or keyboard includes a key retraction mechanism configured to move the chassis relative to the bezel wherein the key holding features of the bezel limit movement of the keycaps in the second direction during movement of the chassis relative to the bezel, while the planar-translation effecting mechanisms move the plurality of keycaps toward a retracted position.
Abstract:
A proximity sensor includes a lead supported on an outer surface of a case structure and a sensor wire that extends from the lead and through an opening in the case structure. The sensor is formed by applying alternating layers of electrically conductive and non-conductive materials in a non-cured state. A base non-conductive layer is applied to an inner surface of the case structure around the sensor wire in a non-cured state. Once cured, a conductive layer is deposited onto the base non-conductive layer and encapsulates the sensor wire. A cover non-conductive layer is then deposited over portions of the conductive layer to insulate the conductive layer. Portions of the non-conductive layer are then removed such that an area of the conductive layer is exposed to define a sensor area.
