Practical applications for touch switch apparatus, including use of touch switch apparatus in connection with other structure, in particular multiposition contactless switches, to emulate mechanical switches.
Abstract:
A touch switch apparatus for detecting the presence of an object such as a human appendage, the apparatus having a touch pad, an electric field generated about the touch pad and also having a preferably integrated and local control circuit connected to the touch pad and to a controlled device. The touch switch apparatus also having at least one of an input circuit portion for providing input signals to a decision circuit, swamping capacitance, active blocking devices, peak detector circuits, and a dual connection output latch circuit portion.
Abstract:
A control system interface integrates an electronic switching or sensing mechanism with an existing or custom-fabricated, functional or decorative equipment panel. The electronic switching or sensing mechanism is located on the rear surface of the equipment panel and a corresponding touch surface is defined on the front surface of the equipment panel. The electronic switching or sending mechanism is responsive to a stimulus in the proximity of the touch surface, and it provides a control signal to a control system when it senses such a stimulus.
Abstract:
A layer of transparent conductive a material is disposed on a surface of a substrate. Further layers of conductive material are deposited on the layer of transparent conductive material or on an opposite surface of the substrate. The layers are selectively etched to yield a layout of pads for mounting electrical components and conductive traces forming an electrical circuit.
Abstract:
A touch, sensor is physically integrated with a light emitting device to provide a switching device with built-in backlighting. In some embodiments, the touch sensor and the light emitting device share electrical components.
Abstract:
The present invention relates to integration of touch switches with integrated thermoformable, injection molded, and other substrates to yield integrated touch switch/control panel assemblies. The ensuant assemblies can include ridges, depressions, anchors, overlaps, rivets and bezels or other housings. They can have any combination of flat and curved surfaces. Further, such assemblies can be incorporated into components of other assemblies, such as automobiles.
Abstract:
A switch panel includes one or more touch responsive switch devices and an integrated decorative fascia. Both the switch devices and decoration are applied to the same substrate, eliminating the need for a separate user interface panel. Each switch device can include one or more electrodes and a circuit for inducing an electric field about the electrode(s) and responding to disturbances to the electric field.

Abstract:
A touch switch apparatus (20) for detecting the presence of an object such as a human appendage, the apparatus having a touch pad (22) and a local control circuit (26) connected to the touch pad and to a control device. The touch pad preferable includes a first electrode (E1) and a second electrode (E2) spaced from and surrounding the first electrode. The control circuit (26) is preferably in integrated circuit form. A signal is provided to the touch pad (22) to generate an electric field thereabout. Introduction of a stimulus near the touch pad (22) disturbs the electric field. The control circuit detects the electric field disturbance in and generates a control signal in response.
