Patent number: 9092129Abstract: A capture device for remote, virtual on screen data input by hand annotation comprises at least three functional layers including a bottom rigid layer, a middle pressure sensor layer and a top flexible layer. The bottom rigid layer has a surface that provides a mechanical support for writing. The middle pressure sensor layer is adapted to measuring a pressure array or map on the capture active area and to send data representing the measured pressure to a personal computer. The top flexible touch-sensitive passive LCD display layer includes an LCD surface by which whatever is written down on the LCD is impressed graphically due to its liquid crystal physical properties wherein applied pressure changes the crystal particles orientation and light properties, such that when a stylus presses against a writing surface thereof, it leaves a visible trace allowing the user to produce a drawing though no real ink has flown.Type: GrantFiled: March 15, 2011Date of Patent: July 28, 2015Assignee: Logitech Europe S.A.Inventors: Samer Abdo, Julien Piot, Greg Dizac, Richard Milhe, Guillaume Bourelly, Matthieu Meisser, Fabiano Pedrotta, Thomas Gaƫtan Brisebras, Candice Patricia Tillitt, Alice Estelle Loeb

Publication number: 20140152624Abstract: An optical touch-sensitive device has the capability to determine touch locations of multiple simultaneous touch events. The touch events disturb optical beams propagating across the touch sensitive surface. With multi-touch events, a single beam can be disturbed by more than one touch event. In one aspect, a non-linear transform is applied to measurements of the optical beams in order to linearize the effects of multiple touch events on a single optical beam. In another aspect, the effect of known touch events (i.e., reference touches) is modeled in advance, and then unknown touch events are determined with respect to the reference touches.Type: ApplicationFiled: November 27, 2013Publication date: June 5, 2014Applicant: Rapt Touch, Inc.Inventors: Julien Piot, Mihailo Kolundzija, Danil Korchagin, Ivan Dokmanic, Martin Vetterli, Owen Drumm

Patent number: 8743083Abstract: A system includes a touchpad sensor array, a touch circuit, and a proximity circuit. The touch circuit executes a touch mode configured to track the position of a user or conductive object on the touchpad sensor array by detecting a change in an electrical property of the touchpad. The proximity circuit executes a proximity detection mode configured to track the position of a user or conductive object near or proximate to the touchpad sensor array by detecting a change in an electrical property of the touchpad. The system is configured to switch from the touch mode to the proximity detection mode after a predetermined period of inactivity, where the proximity detection mode can operate at one or more reduced polling rates, resulting in a reduced overall power dissipation. The system is configured to switch back to the touch mode when activity is detected by the proximity circuit.Type: GrantFiled: October 13, 2011Date of Patent: June 3, 2014Assignee: Logitech Europe, S.A.Inventors: Jean-Daniel Zanone, Mathieu Meisser, Simone Arrigo, Julien Piot

Publication number: 20140028629Abstract: An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events. The optical touch-sensitive device includes multiple emitters and detectors coupled with an optical coupler assembly through a waveguide on the surface on the optical-touch sensitive device. Each emitter produces optical beams which propagate in the waveguide via total internal reflection and are received by the detectors. Touch events disturb the optical beams, and are determined based on the disturbances. The optical touch-sensitive device further includes an intermediate layer interposed between the waveguide and a display surface. The intermediate layer preserves optical beam propagation in the waveguide and is transparent to visible light. The optical touch-sensitive device may further include at least one frame zone, at least one dead zone, and/or at least one fixed graphics zone.Type: ApplicationFiled: July 22, 2013Publication date: January 30, 2014Inventors: Owen Drumm, Julien Piot, Robert Copperwhite

Patent number: 8633893Abstract: A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.Type: GrantFiled: January 10, 2013Date of Patent: January 21, 2014Assignee: Logitech Europe S.A.Inventors: Florian Max Kehlstadt, Berni Joss, Julien Piot, Marc Bidiville, Laurent Plancherel, Baptiste Merminod, Jean-Luc Dupraz, Maxime Marini, Chiu Yu
