Abstract:
Disclosed is an active skin including: a tactile sensor substrate which includes a first film including a dielectric elastic material and formed with a plurality of sensing points, and a pair of first electrodes respectively formed on upper and lower sides of the sensing point; a tactile actuator substrate which includes a second film including a dielectric elastic material and formed with a plurality of actuating points, and a pair of second electrodes respectively formed on upper and lower sides of the actuating point; and an insulating layer which is interposed between the tactile sensor substrate and the tactile actuator substrate and couples the tactile sensor substrate and the tactile actuator substrate. With this, a tactile sensor and a tactile actuator are integrated, so that there is provided an interactive tactile interface to not only feel like a human's skin but also actively move like a muscle.
Abstract:
A push switch structure for a display is provided, wherein the elastic sealing member 84 adheres to the periphery of the key switch body 83 which is capable of transmitting indication of the display 78; the key switch body is inserted into the opening portion of the elastic sealing member and the collar portion of the key switch body coheres to the elastic sealing member and is pressed with the cover; the key switch body is provided with the accommodating recess for a push-button switch 99; the key switch body is provided with the transparent electrode and the elastic sealing member coheres to the transparent electrode substrate arranged on the front of the display; an assembled unit 76 of the elastic sealing member and the key switch body is assembled to the display case 77, which is assembled to an assembly 96 of the control substrate 79 and the display; the elastic sealing member coheres to the front of the accommodating portion 87 and the display is put into close contact with the backside of the accommodating portion 87; and a part of the elastic sealing member is formed in a sector-shape between the key switch bodies and is bent to form the resilient portion. Thus, dust-and-waterproofing of the push switch for the display can be attained.
Abstract:
A flexible membrane touch panel switch having contacts comprised of a first set of thin conductive metal film strips formed on a first layer, and of a second set of thin conductive metal film strips orthogonal to the first set and formed on a second layer, the second layer being spaced apart from and selectively movable into contact with the first layer, the panel further having silver conductive leads formed on each of the layers, each lead being integrally affixed at one end to, in electrical contact with, and extending from one of the strips for connection to external circuitry.
Abstract:
An improved membrane switch (10) is the subject matter of this patent. The switch (10) includes a pair of transparent, laminar contacts (16, 18) sandwiching a spacer (30) therebetween. The spacer (30) has a window (36) formed therein so that the contacts (16, 18) can be engaged at the location of the window (36) by the application of pressure to one of the contacts (16, 18). Engagement of the contacts (16, 18) closes a circuit to effect a desired function.
Abstract:
A keyswitch uses a combination of springs connected in serial for providing a return force to a keycap of the keyswitch. When the keycap moves toward a base of the keyswitch beyond a transition position, one of the springs stops continuously deforming. It leads to an increment of the elastic coefficient of the combination of springs and an increment of the elastic stored energy by the combination of springs. Therefore, during a pressing on the keycap, the keycap can provide a light force feedback and then a heavy force feedback to a user. Further, the keyswitch can use a switch with a lateral motion, which can reduce influence of a resilient force produced by the switch on the up and down movement of the keycap. The keyswitch also can use an elastic piece disposed beside the keycap, which can provide a tactile feedback to the user.
Abstract:
A touch screen assembly includes a first outer layer (102) and a second outer layer (110) separated by a separator layer (118). The first and second outer layers are transparent, and the separator layer has openings (120) at button locations where buttons will be defined. On each of the outer layers is a layer of transparent conductor (104, 112). On the first outer layer the transparent conductor is in the form of a contiguous trace or path. The touch screen assembly is placed on a display element (203) and images displayed on the display element can be seen through the touch screen assembly. Images such as characters are displayed at button locations, and when a user presses on one of the images the conductive layers on the first and second outer layers of the touch screen assembly come into contact.
Abstract:
A sensor/switching device configuration that includes a substrate and at least one element imprinted on the substrate containing an electroconductive material.
Abstract:
An upper electrode plate has a 0.15 to 0.8 mm thick optically isotropic heat-resistant transparent resin plate having a glass transition temperature characteristic of not less than 150null C. The heat-resistant transparent resin plate is laminated directly or indirectly on a quarter wave plate all over their surfaces.
Abstract:
A transparent keyboard switch which is suitable for use in switch arrays is disclosed. Switch nomenclature may be positioned behind the switch and viewed from in front of the switch. The transparent switch comprises a relatively rigid electrically insulating transparent substrate having a "lower" electrode disposed on the upper surface thereof and a relatively flexible transparent film having an "upper" electrode disposed on the underside thereof and a layer of electrically insulating fluid spacing the upper electrode from the lower electrode. The switch is rendered conductive by pressing on the flexible film to locally displace the electrically insulating fluid from between upper and lower switch electrodes and bring them into contact, thereby making the switch a closed circuit.
Abstract:
A switch having a transparent area and suitable for placing over a video display without obscuring the information displayed beneath the switch. The switch comprises an elastically bendable conducting strip which, when a top transparent member of the switch is pushed, is forced into contact with a conducting area on the top transparent member. The natural elasticity in the bendable strip serves to break the contact between the conducting area and the bendable strip when the switch is released.
