Publication number: 20070139379Abstract: 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: ApplicationFiled: January 24, 2007Publication date: June 21, 2007Applicant: Logitech Europe S.A.Inventors: Florian Kehlstadt, Berni Joss, Julien Piot, Marc Bidiville, Laurent Plancherel, Baptiste Merminod, Jean-Luc Dupraz, Maxime Marini, Chiu Yu

Publication number: 20070018970Abstract: An optical feedback mechanism corresponding to a variation in input by a user's digit on an input element. The variation in input can be movement by the user's finger, or a change in the amount of pressure or force applied to a button. In one embodiment, the optical feedback is a linear light array adjacent a solid-state scroll/zoom sensor, with the light corresponding to the finger position. Alternately, a solid state button could provide feedback corresponding to the amount of pressure in the form of a change in intensity, color or blinking. In one embodiment, the input signal from an input element alternates between a scroll, zoom and/or other functions depending on the current application.Type: ApplicationFiled: May 4, 2006Publication date: January 25, 2007Applicant: Logitech Europe S.A.Inventors: Alain Tabasso, Sergio Lazzarotto, Patrick Monney, Daniel Bonanno, Nicholas Chauvin, Olivier Mathis, Florian Kehlstadt, Marc Bidiville, Laurent Plancherel, Jean-Luc Dupraz, Maxime Marini

Patent number: 6937225Abstract: The method and system serve to notify the user of an event through a control device. Active notification takes place even when the computer sound and screen are disabled, for example, when in a power saving mode or screen saving mode. Notification may include visual notification, audio notification, vibratory notification, or tactile notification. Tactile notification can also serve to provide a private notification system which will not alert or disturb other people in the vicinity of the user. Such tactile notification can be provided by means of a texture change in the surface of the control device. One way in which this could be done is by raising a plurality of pegs through the surface of a control device to change its texture.Type: GrantFiled: December 27, 2000Date of Patent: August 30, 2005Assignee: Logitech Europe S.A.Inventors: Florian Kehlstadt, Antoine Merminod, Baptiste Merminod, Olivier Campiche, Julien Piot, Jean-Luc Dupraz, Laurent Plancherel, Guy Tiphane

Patent number: 6248018Abstract: A micro-stick in which the movement of the micro-stick is detected inductively. The micro-stick is connected to an actuator element which varies interaction between an electromagnetic element and a number of conductive coils. In one embodiment, the coils are mounted on a printed circuit board mounted beneath the micro-stick. The micro-stick is mounted on a plate having a number of pins extending through the circuit board. On the other side of the circuit board is a flexible metal sheet which is contacted by the pins, and moved away from the coils in a direction in which the micro-stick is tilted. This increased separation of the metal sheet from the coils can then be detected.Type: GrantFiled: September 15, 1998Date of Patent: June 19, 2001Assignee: Logitech, Inc.Inventors: Florian Kehlstadt, Antoine Merminod, Marc Bidiville, René Sommer, Dénes Karaï

Patent number: 5911627Abstract: A joystick having an electromagnetic element coupled to a movable stick, with at least a pair of orthogonal coils on an underlying substrate. Alternately, the coils and electromagnetic elements can be reversed. The movement of the stick is detected by the amount of overlap of the electromagnetic element and the coils in each direction. The quality factor of the coil changes as more or less of the coil is overlapped, which can be measured by an electric circuit to determine the direction of movement and the amount of movement of the joystick. The electromagnetic element could be, for instance, a conductive steel plate, or a piece of another metal or of another conductive material, or ferrite particles. The coil could be wound (preferably on air only or, if needed to reach a higher value of inductance, on a magnetic core, provided this is small enough to not hide the effect of the mobile electromagnetic element).Type: GrantFiled: October 23, 1997Date of Patent: June 15, 1999Assignee: Logitech, Inc.Inventors: Julien Piot, Patrick Favre, Marc Bidiville, Florian Kehlstadt, Antoine Merminod
