Assignee:

Synaptics Incorporated - San Jose CA

International Classification:

G09G 5/08

US Classification:

345173, 345179, 178 1806

Abstract:

A transparent, capacitive sensing system particularly well suited for input to electronic devices is described. The sensing system can be used to emulate physical buttons or slider switches that are either displayed on an active display device or printed on an underlying surface. The capacitive sensor can further be used as an input device for a graphical user interface, especially if overlaid on top of an active display device like an LCD screen to sense finger position (X/Y position) and contact area (Z) over the display. In addition, the sensor can be made with flexible material for touch sensing on a three-dimensional surface. Because the sensor is substantially transparent, the underlying surface can be viewed through the sensor. This allows the underlying area to be used for alternative applications that may not necessarily be related to the sensing system. Examples include advertising, an additional user interface display, or apparatus such as a camera or a biometric security device.

Inventors:

Richard R. Schediwy - Union City CA, US
Bob Lee MacKey - San Jose CA, US

Assignee:

Synaptics Incorporated - San Jose CA

International Classification:

H02H 7/20
H02H 1/00

US Classification:

361112

Abstract:

One embodiment in accordance with the invention includes a capacitive sensor apparatus that includes a sensing element and a ground element. The capacitive sensor apparatus also includes a floating strike ring that is electrically isolated from the sensing element. The floating strike ring and the ground element form a spark gap. The spark gap is for reducing potential damage to the capacitive sensor apparatus that can be caused by an electrostatic discharge encountered by the capacitive sensor apparatus.

Assignee:

Synaptics Incorporated - San Jose CA

International Classification:

G06F 3/041

US Classification:

345173, 345174

Abstract:

The embodiments described herein provide devices, systems and methods that facilitate improved performance in an input device. The input device, for example, may include an input surface configured to rotate about a first axis, a proximity sensor configured to sense an input object in a sensing region proximate to the input surface of the input device, a force sensor configured to sense a force applied to the input surface of the input device, and a processing system communicatively coupled to the proximity sensor and the force sensor. The processing system may be configured to determine a position of the input object in the sensing region, and determine force information for the input object based upon the position of the input object, the force applied to the input surface, and a location of the force sensor relative to the first axis.

International Classification:

G01R 27/26

US Classification:

324663

Abstract:

A solid state navigation device comprises a solid state dielectric nub with an upper surface configured for being contacted by an object. The upper surface comprises an intervening dielectric layer. A plurality of conductor electrodes is disposed beneath at least a portion of the intervening dielectric layer. The plurality of conductor electrodes is configured to sense a change in capacitance coupling of the plurality of conductor electrodes to the object. The change in capacitance is caused by the object contacting and moving about the upper surface.
