Publication number: 20080192026Abstract: Systems and methods for detecting a position of an object in a sensing region are disclosed. One system includes a position sensor having an opaque capacitive proximity sensor, a light source, and a light conductor coupled to the light source and at least partially disposed over the opaque sensor, the light conductor configured to transmit at least a portion of the light from the light source to generate driven light effects in the sensing region. The system further includes a processor configured to control production of the light, and a display configured to illustrate a digital representation based on the position. A method includes the steps of sensing a position of an object in the sensing region based on a conductive property of the object, controlling light produced by a light source, and generating driven light effects in the sensing region using at least a portion of the light.Type: ApplicationFiled: April 10, 2008Publication date: August 14, 2008Applicant: SYNAPTICS INCORPORATEDInventors: Bob Lee MACKEY, Shawn P.

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.Type: ApplicationFiled: February 13, 2007Publication date: August 14, 2008Inventors: Richard R.

Patent number: 7382360Abstract: Methods and systems are provided for producing a light effect on a touchpad or other position sensor. In one aspect, a position sensor for detecting a position of an object suitably includes a sensor, a light source, and a light conductor at least partially located between the sensor and the object. The light conductor is configured to transmit light from the light source to produce a light effect that alters the appearance of the position sensor. Because the light conductor is located between the sensor and the object, the sensor need not be made from transparent or translucent material, thereby significantly reducing the cost of the sensor. In a further aspect, the position sensor includes at least one marking or pattern in proximity to the light conductor such that the marking can be made visible by at least a component of the light to produce an image of a soft control, logo, ornamental design, status indicator or the like.Type: GrantFiled: April 15, 2003Date of Patent: June 3, 2008Assignee: Synaptics IncorporatedInventors: Bob Lee Mackey, Shawn P.

Patent number: 7030860Abstract: 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.Type: GrantFiled: October 8, 1999Date of Patent: April 18, 2006Assignee: Synaptics IncorporatedInventors: Andrew C.

Patent number: 5943052Abstract: An apparatus for touchpad-based scroll control and method for scroll control comprising a data packet processor working in conjunction with a touchpad. A scroll zone, having a central axis, is defined on the touchpad. After detecting a user running a finger on the touchpad in a direction substantially parallel to an axis running the length of the scroll zone, the processor software sends scrolling messages to the operating system or application that owns an active window. The packet processing software is configured to not scroll on motions that are not substantially parallel to the axis of the scroll zone, thereby avoiding unwanted interference with normal program function, and also stops scrolling when the user lifts the scroll-activating finger or moves it in direction substantially perpendicular to the scroll zone.Type: GrantFiled: August 12, 1997Date of Patent: August 24, 1999Assignee: Synaptics, IncorporatedInventors: Timothy Allen, Shawn P.
