Patent number: 10741740Abstract: A thermo-electric generator includes a semiconductor membrane with a phononic structure containing at least one P-N junction. The membrane is suspended between a first support designed to be coupled to a cold thermal source and a second support designed to be coupled to a hot thermal source. The structure for suspending the membrane has an architecture allowing the heat flux to be redistributed within the plane of the membrane.Type: GrantFiled: July 27, 2018Date of Patent: August 11, 2020Assignee: STMicroelectronics (Crolles 2) SASInventors: Emmanuel Dubois, Jean-Francois Robillard, Stephane Monfray, Thomas Skotnicki

Patent number: 6879316Abstract: An input device with a pressure-sensitive element using a pressure sensing resistor. A solid elastomeric material is mounted over the pressure sensing resistor to transfer a force from the user's finger to the pressure sensitive resistor without visible deformation of the elastomeric material. This provides a comfortable button for a user which does not require the compression of a domed cap to provide pressure-sensing input. In another aspect of the invention, a pressure-sensing input element utilizes both the amount of pressure and the amount of time to determine the type of signal provided to the electronic system. In another aspect of the present invention, an input device contains a first scrolling element (e.g. a wheel) and includes a switch button mounted close to the scrolling element to activate continuous scrolling.Type: GrantFiled: December 11, 2001Date of Patent: April 12, 2005Assignee: Logitech Europe, S.A.Inventors: Florian Max Kehlstadt, Baptiste Merminod, Laurent Plancherel, Emmanuel Dubois

Publication number: 20050024346Abstract: A digital writing system according to one embodiment of the present invention captures handwritten gestures in addition to text and patterns. It may include, among other things, a digital pen, special erasable ink and paper, and application software for the managing of captured files with a corresponding user interface. A digital pen according to one embodiment of the present invention may include character recognition subsystem, function control subsystem with selection mechanisms, a processor subsystem, memory subsystems, and wired or wireless communication subsystems. In addition, embodiments of a digital pen according to the present invention may include additional functional features including, for example, a user notification (e.g., alarm) feature, a digital camera feature, voice recording and recognition features, calendar features, calculator features, biometric sensor features, and the like.Type: ApplicationFiled: July 30, 2003Publication date: February 3, 2005Inventors: Jean-Luc Dupraz, Florian Kehlstadt, Emmanuel Dubois, Fabrice Lauper
