Patent number: 9086749Abstract: Implementations disclosed herein provide systems and methods for improved processing of touch sensor data with improved scalability and reduced standby power. Touch-related algorithms may be partitioned between the touch screen controller and the application processor or host such that the system can function with low standby power and low interface bandwidth while providing a scalable solution for enhanced user experience. In some aspects, a small digital processing engine and memory remains in the analog front end (AFE) of the touch screen controller to perform imagine forming algorithms that are mostly related to noise reduction and filtering schemes.Type: GrantFiled: August 30, 2013Date of Patent: July 21, 2015Assignee: QUALCOMM INCORPORATEDInventors: Fariborz Pourbigharaz, Louis Dominic Oliveira, Raghukul Tilak, Suhail Jalil

Publication number: 20140306910Abstract: Systems, apparatus and methods for touch detection are presented. Multiple fingers (two to five) from one hand are tracked based on fast moving fingers being group in a fixed position relative to one another. Touch points are matched from a first time to a second time wherein the matching minimizes relative movement between the tracked fingers. In some embodiments, a touch sensor receives first and second touch data comprising touch detections. A processor matches, for several candidate matches, touch detections from a first set to a second set. For each match, the processor further computes a rotation and translation matrix between the first set and the second set; applies the rotation and translation matrix to the first set to determine a result; and calculate a Euclidian distance between the result and the second set. Finally, the processor selects a match, from the several matches, having a minimum Euclidian distance.Type: ApplicationFiled: April 11, 2014Publication date: October 16, 2014Applicant: QUALCOMM IncorporatedInventors: William Yee-Ming Huang, Suhail Jalil, Raghukul Tilak, Mohamed Imtiaz Ahmed
