Publication number: 20140015751Abstract: A device and method include an enclosure having a top layer with an external touch surface and an oppositely disposed back surface, a flexible substrate including a first portion affixed to the back surface, a second portion separate from the first portion, and an intermediate portion between the first second portions. An array of capacitive sensors is configured to sense objects proximate the external surface. A processor mounted to the second portion is configured to obtain signals from the sensors, determine object motion proximate the external surface using the signals, cause scrolling in response the object moving along a first axis, cause continued scrolling in response to the object lifting with a substantially non-zero speed along the first axis, and to not cause continued scrolling in response the object lifting with a substantially zero speed along the first axis.Type: ApplicationFiled: September 10, 2013Publication date: January 16, 2014Applicant: SYNAPTICS INCORPORATEDInventors: David W. Gillespie, Shawn P. Day, Raymond A. Trent, JR., Scott J. Shaw, Andrew M. Errington

Publication number: 20140009397Abstract: A capacitive sensing device and method include a touch surface, a capacitive touch sensor coupled to the touch surface and configured to measure finger motion along the touch surface, and a processor in operative communication with the capacitive touch sensor. The processor is configured to generate a scrolling command in response to finger motion along the touch surface, cease the scrolling command without substantially continuing generating the scrolling command upon the finger lifting from the touch surface when the finger is stationary prior to lifting from the touch surface, and continue generating the scrolling command for a time after the finger lifting from the touch surface to emulate coasting responsive to finger motion prior the finger lifting.Type: ApplicationFiled: September 10, 2013Publication date: January 9, 2014Inventors: David W. Gillespie, Shawn P. Day, Raymond A. Trent, JR., Scott J. Shaw, Andrew M. Errington

Publication number: 20090184940Abstract: A low-cost x-y digitizing system for use in consumer electronic devices, such as portable digital assistants, mobile telephones, web browsers and the like. The digitizer includes a resonant stylus, an excitation winding for energizing the resonant stylus and a set of sensor windings for sensing the signal generated by the stylus, from which the x-y position of the stylus is determined. A novel stylus design is described together with novel digitizer windings and novel excitation and processing circuitry.Type: ApplicationFiled: March 3, 2009Publication date: July 23, 2009Applicant: Synaptics (UK) LimitedInventors: Christopher J.
