Abstract:
A touch control keyboard includes a plurality of keycaps, a plurality of touch key parts, a plurality pairs of conductive distributions, a first circuit board, and a second circuit board. An upper part of each keycap includes a touch key part having a coupling capacitor. The touch key parts and the pair of conductive distributions and the first circuit board are electrically connected. The first circuit board detects the coupling capacitors of the touch key parts by using the pair of conductive distributions to generate a first key signal. The second circuit board detects keystrokes of the keycaps to generate a second key signal.
Abstract:
A low profile keyboard backlight module includes an electrically insulative bottom membrane layer, an intermediate membrane layer including a conducting layer, an insulative layer and a light-emitting layer attached together through lamination and bonded to the top surface of the bottom membrane layer, and an electrically insulative top membrane layer bonded to a top surface of the intermediate membrane layer opposite to the bottom membrane layer and having an integrated elastic layer located at a top surface thereof to support a set of keys. Thus, the low profile keyboard backlight module provides optimal waterproof effects and is practical for use in an electronic product having light, thin, short and small characteristics.

Abstract:
A multi-contact tactile sensor including an elastically deformable interaction layer and a supporting layer, a lower surface of the interaction layer including an array of strip conductors and an upper surface of the supporting layer including an array of strip conductors that are not parallel to the array of strip conductors on the interaction layer. The interaction layer and the supporting layer are separated by a first series of rigid insulating spacers. A second series of conducting spacers is in contact with at least one of the two arrays of strip conductors. The impedance and dimensions of the spacers of the second series are determined to prevent contact at rest and enable local contact during deformation of the interaction layer between the spacers of the second series and the array of strip conductors of the layer opposite the spacers. A controller can control one such sensor, a multi-contact tactile screen can include one such sensor, and a keyboard including a set of discrete keys can be formed by one such sensor.

Abstract:
An in-mould molding touch module includes a plastic film, a touch circuit and a molding rind. The plastic film includes an inner surface and an outer surface for handling and touching. At least one region of the inner surface and a corresponding region of the outer surface define a touch area. The touch circuit is arranged on the inner surface in the touch area. The molding rind is integrated on the inner surface by an in-mould injecting mode to contain the touch circuit for forming a one-piece body. In addition, the invention also provides a method for manufacturing an in-mould molding touch module.
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 variable resistance transducer responsive to an applied pressure including a smooth resistive layer on a flexible substrate and deposited thereon by printing or imaging technology, small points of nonconductive or semiconductive material, and resistive interdigitating fingers where in one finger is a wiper so that position on the resistive layer can be sensed.
