Patent number: 9778798Abstract: Embodiments of the invention generate a voltage gradient across a sensor electrode by driving a negative and positive voltage on respective ends of the electrode to identify a location of an input object. Because both negative and positive voltages are used, one location on the sensor electrode will be at a reference voltage (e.g., system ground). This location is used to divide the sensor electrode into two different regions. Based on measuring a change in charge relative to a baseline, the input device identifies in which of the two regions the input object is located. The input device can then generate a new voltage gradient to shift the location of the reference voltage into the identified region thereby dividing the region into two sub-regions. By iteratively repeating this process using progressively small sub-regions, the input device can identify the location of the input object.Type: GrantFiled: June 30, 2014Date of Patent: October 3, 2017Assignee: SYNAPTICS INCORPORATEDInventor: David Hoch
