Abstract:
Control of multiple functions of an electronic device is provided by using a single control element (102) including a switch body (312) adjustable between multiple switch positions, a primary actuator (302) with lateral (302b) and distal surface (302a) portions extending from the switch body and configured for adjusting the switch body between the switch positions, and a pressure sensor (314) operable via an activation force at the lateral surfaces of the primary actuator. A first function can be controlled responsive to motion of the primary actuator during an activation of the pressure sensor. Additionally, a second function can be controlled responsive to the motion of the primary actuator of the control element exclusive of the activation of the pressure sensor. Further, a third function can be controlled in responsive to activation of the pressure sensor for at least a first period of time exclusive of motion of the primary actuator.

Abstract:
Ein Nockenrad (2) mit zirkulär verteilten Zahnnocken (9) ist über einem schwenkbaren Schaltnocken (8, 20) drehbar, der geringfügig zwischen diese ragt. Der Schaltnocken (8, 20) ist fest mit seitlich abstehenden Kontaktarmen (12, 36) verbunden, deren freie Enden in einer Mittellage mit Abstand über Gegenkontakten (14) einer Leiterplatte (4) stehen. Beim Drehen des Nockenrades (2) wird der Schaltnocken (8, 20) in diese Richtung mitgenommen und soweit geschwenkt, daß der in die Drehrichtung weisende Kontaktarm (12, 36) auf den zugehörigen Gegenkontakt kontaktgebend aufsetzt. Beim Weiterdrehen schnappt der Schaltnocken (8) unter der Wirkung einer rückstellenden Stützfeder (11, 26) in seine mittlere Ausgangslage zurück, wobei der Kontakt wieder getrennt wird. Durch diese Anordnung wird der Aufbau des Impulsgenerators vereinfacht und dessen Funktionssicherheit erhöht.

A switching element (10) for a rotary or linear encoder which generates pulse signals indicative of linear or rotary position, and direction , and rate of change of such position. The invention is characterized by use of a patterned and cured solder-mask (29) material which defines conductive (32), insulated or non-conductive surface (33), with a pattern of conductive wiper-contacting segments (31) there between. The invention enables fast and economical fabrication as compared to known encoder switching elements.

An encoder assembly is disclosed which comprises a drum-like rotor having an outer circumference and a central bore with at least one slot, and a plurality of encoder elements arrayed around the outer circumference of the drum-like rotor. The assembly further comprises a shaft having a diameter sized to fit into the central bore, and having a flattened key which is configured to fit into the at least one slot. The rotor and shaft fit into a housing having an inner section sized to receive the drum-like rotor and encoder elements. The inner section has an opening along one side such that the inner section incompletely encloses the circumference of the rotor. There is also at least one spring contact locatable within the housing such that it can make contact with the encoder elements through the opening in the inner section of the housing.
Abstract:
An integrated digital electronic encoder that converts mechanical movement of a device input into a signal that can be applied to particular purposes is described. The encoder and associated signal conditioning and processing circuitry are embedded together as a single unit for simplicity of assembly into particular applications, and reliability. The integrated digital electronic encoder includes a substrate with first and second substantially opposed major surfaces, and a digital encoder formed on the first major surface of the substrate. The encoder comprises an actuation shaft, and the encoder is configured to generate electrical signals in response to movement of the actuation shaft. Electronic circuitry is attached to the second major surface of the substrate, preferably using surface mount technology. The electronic circuitry is electrically connected with the digital encoder to process the signals produced by the encoder. The electronic circuitry includes programmable logic to provide multiple function capability to the integrated digital encoder. The electronic circuitry also includes supervisory power circuitry for conditioning the power supplied to the programmable logic, and output circuitry such as a communication interface.
