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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Techniques to determine X-position in gradient sensors","description":"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 obj","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9778798","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
