Inventors: Peter W. Richards, Thomas Samuel Elliot, Shelten Gee Jao Yuen (Fitbit, Inc.)

04/03/14 - 20140092052 - Frustrated total internal reflection and capacitive sensing
Detecting force and touch using FTIR and capacitive location. FTIR determines applied force by the user's finger within infrared transmit lines on a touch device. A pattern of such lines determine optical coupling with the touch device. Capacitive sensing can determine (A) where the finger actually touches, so the touch...
Inventors: Martin P. Grunthaner, Peter W. Richards, Romain A. Teil, Steven P. Hotelling (Apple Inc.)

10/10/13 - 20130265242 - Touch sensor common mode noise recovery
A touch sensor panel configured to minimize the effect on touch or proximity event detection caused by a common mode noise event. The touch sensor panel includes circuitry that works to minimize the amount of time that the touch sensor panel is unable to accurately sense touch and proximity events...
Inventors: Peter W. Richards, Christoph Horst Krah, Martin Paul Grunthaner

04/25/13 - 20130099854 - Noise suppression circuit for power adapter
A noise suppression circuit for a power adapter is disclosed. The noise suppression circuit can reduce or eliminate adapter-induced noise that could interfere with an electronic device powered by the adapter. In one example, the noise suppression circuit can include an active circuit to detect and attenuate or cancel the...
Inventors: Peter W. Richards, Steven Porter Hotelling

04/19/12 - 20120092285 - Touch sensor arrays with integrated inter-layer contacts
Touch pad structures are provided that gather touch sensor data. The data may be used to control a computer or other electronic device. The touch pad structures may be integrated into a computer or other computing equipment or may be provided as a stand-alone accessory. The touch pad structures may...
Inventors: Jay Kevin Osborn, Peter W. Richards

04/19/12 - 20120092270 - Touch sensor with secondary sensor and ground shield
A touch sensor pattern with a secondary sensor formed substantially as part of the touch sensor pattern is provided. By forming the secondary sensor substantially as part of the touch sensor pattern, where the secondary sensor can be held at a steady state or ground during a touch scan cycle...
Inventors: Benjamin B. Lyon, Peter W. Richards

The bibliographic references displayed about Peter W. Richards's patents are for a recent sample of Peter W. Richards's publicly published patent applications. The inventor/author may have additional bibliographic citations listed at the USPTO.gov. FreshPatents.com is not associated or affiliated in any way with the author/inventor or the United States Patent/Trademark Office but is providing this non-comprehensive sample listing for educational and research purposes using public bibliographic data published and disseminated from the United States Patent/Trademark Office public datafeed. This information is also available for free on the USPTO.gov website. If Peter W. Richards filed recent patent applications under another name, spelling or location then those applications could be listed on an alternate page. If no bibliographic references are listed here, it is possible there are no recent filings or there is a technical issue with the listing--in that case, we recommend doing a search on the USPTO.gov website.
