摘要:
L'invention concerne un dispositif de contrôle et/ou de commande d'éléments d'équipements (2) d'un véhicule automobile. Selon l'invention, le dispositif comprend une dalle tactile (4) pourvue d'une surface active (5) dotée d'au moins un capteur (6) relié à une unité électronique de traitement (7) de manière à localiser la provenance d'une onde acoustique (9) à laquelle est soumise la surface active (5) et à commander et/ou contrôler un élément d'équipement (2) du véhicule associé à la zone de la surface active (5) de laquelle provient l'onde acoustique (9) et en ce qu'il comprend au moins un bouton (10) de commande et/ou de contrôle pourvu d'un doigt d'indexation (11) manuellement mobile sur la surface active (5) de la dalle tactile (4) ondulée sur le chemin de déplacement du doigt d'indexation (11), de manière que le doigt (11) engendre une onde de choc acoustique (9) à chaque passage du doigt (11) d'une bosse (14) à un creux (15) de la surface ondulée de la dalle tactile (4). L'invention trouve application dans le domaine de l'automobile.
摘要:
An acoustic wave switch (12) includes a substrate (14) with an acoustic wave cavity (20) formed therein such that the mass per unit area of the acoustic cavity is greater than the mass per unit area of the substrate adjacent the cavity. A transducer (26) is mounted on the acoustic cavity for generating an acoustic wave that is substantially trapped in the cavity. A touch on the touch surface (28) of the acoustic wave cavity (20) absorbs acoustic wave energy and produces a detectable change in the impedance of the transducer (26). The acoustic wave switch (12) has a high Q so as to enable a touch to be detected by extremely simple, low-cost circuitry. The acoustic wave switch of the present invention is rugged, explosion proof, operates in the presence of liquids and other contaminants, has a low power consumption and can be incorporated and integrally formed in a wall of a housing for a device.

L'invention trouve application dans le domaine automobile.
摘要:
A touch panel (4) and an operating section (30) are provided on a display means (2). A permanent magnet (52) is attached to a push button (32) and a magnetic metallic plate (58) is fitted to a supporting frame (36). When the button (32) is pressed down toward the panel (4) against the magnetic attraction between the magnet (52) and the metallic plate (58), an operating front-end section (46) operates a touch switch (4a). While the button (32) moves, a sense of stroke is given. In the initial stage of the movement, the magnetic attraction abruptly decreases and the operator of the button (32) feels a sense of click. Since the operator feels the senses of stroke and click when he operates the button (32), the operability of the thin switch device is improved while taking the advantage that the touch panel (4) is thin.

摘要:
A key activation system for use in an electronic device, such as a handheld communication device is provided. The system comprises an activation mechanism associated with a key in the system, a first feedback system and a second feedback system. The activation mechanism is associated with the key activation system and provides a first feedback sense when the activation mechanism has triggered the first activation condition. The second feedback system provides a second feedback sense indicating when the key triggers the second activation condition. In the system, the second feedback system operates independently from the activation mechanism and the first activation condition is triggered before the second activation condition when the activation mechanism is initially engaged. An activation mechanism may be centrally located for a set of keys.

An acoustic wave switch includes a substrate (14) with an acoustic wave cavity (20) formed therein such that the mass per unit area of the acoustic cavity is greater than the mass per unit area of the substrate adjacent the cavity. A transducer (26) is mounted on the acoustic cavity (20) for generating an acoustic wave that is substantially trapped in the cavity. A touch on the touch surface (28) of the acoustic wave cavity absorbs acoustic wave energy and produces a detectable change in the impedance of the transducer. Various feedback mechanisms can be employed to provide a user with a tactile, audible and/or visual response indicating actuation of the switch by a touch.
