Patent number: 8188676Abstract: At least some embodiments include a LED driver system. The system includes multiple branches of series-coupled LEDs, multiple current sources, and control logic. Each of the current sources is coupled to a separate branch of series-coupled LEDs. The control logic is coupled to the current sources, and is configured to regulate current through each branch based at least in part on a feedback voltage measured at a node in one of the branches.Type: GrantFiled: May 3, 2011Date of Patent: May 29, 2012Assignee: Texas Instruments IncorporatedInventors: Paolo Cusinato, Frederic Ballin, Lorenzo Indiani, Philippe Perney, Gwenaelle Merrien, Francois Bauduin

Patent number: 7639745Abstract: A serial data link (10) includes a transmitter (12) using a differential transmitter cell (20) to transmit data using differential signals and a receiver (14) using a differential receiver cell (22) to receive differential signals. When the transmitter (12) is in a power-down state, the differential signals from the differential transmitter cell (20) are set to an illegal state that is detected by the receiver cell (22). Upon detecting the illegal state, unnecessary circuitry in the receiver (14) is shut off or placed in a low power state to conserve energy. When data transmission resumes, the receiver cell (22) automatically restores power to its circuitry and resumes receiving data.Type: GrantFiled: April 19, 2002Date of Patent: December 29, 2009Assignee: Texas Instruments IncorporatedInventors: Andrea Bonelli, Francois Bauduin

Patent number: 6218659Abstract: A dual-layer optical ball for use in a cursor control pointing device. The ball is illuminated by a light source that emits light signals at, at least, a first wavelength, the ball having an inner layer surface that is capable of diffusing a light signal and an outer layer having a substantially smooth surface that surrounds the inner layer. The outer layer is substantially transparent to light at the first frequency. The inner layer diffuses the light signals at different intensities depending upon an the area of the inner surface that is illuminated.Type: GrantFiled: December 8, 1999Date of Patent: April 17, 2001Assignee: Logitech, Inc.Inventors: Marc Bidiville, Eric Raeber, Javier Arreguit, Harthmuth Buczek, Floris A.
