Patent number: 7061462Abstract: The invention relates to the problem of the driving of the LCD electrooptic-switching element (1) with alternating, square-wave electric signals, the amplitude of witch can vary between different voltage levels in correspondence with the actual functioning state of the LCD electrooptic-switching element. The polarity changes of the electric driving signals is controlled by the integrator (9), integrating the difference of the electric potentials on the driving electrodes (2, 3) of the LCD electrooptic-switching element, in such a way that the value of time integral of the driving electric field is always kept within a selected interval. Besides this the time dependence of the electric driving signals can be optionally modified so that with every change of the polarity of the electric driving signals, the potentials on both driving electrodes get the same value for a time, which is significantly shorter than the switching time of the LCD electrooptic switching element.Type: GrantFiled: October 25, 1999Date of Patent: June 13, 2006Inventors: Janez Pir{hacek over (s)}, Bojan Marin, Sivija Pir{hacek over (s)}, Du{hacek over (s)}an Ponikvar

Patent number: 7061478Abstract: A CMOS output cell with multiple output modes is disclosed. In one embodiment, the cell drives a differential output signal on two output pads in one mode and two single-ended output signals on the two output pads in another mode. Differential and single-ended driver transistors are included for this purpose. A logic circuit disables unused driver transistors, and supplies appropriate drive signals to those transistors for each mode. When disabled, the driver transistors serve an electrostatic discharge (ESD) protection function, at least partially alleviating the need for ESD-specific devices in the cell. The diminished need for ESD-specific devices allows the cell to offer a highly flexible chip interface, with little or no increase in circuit area over a conventional cell that offers only single-ended or differential output.Type: GrantFiled: April 7, 2003Date of Patent: June 13, 2006Assignee: Pixelworks, Inc.Inventor: Todd K.

Patent number: 7042442Abstract: The invention uses a recognition system of gestures that maps sequences of gestures to keys strings. In the practice of this invention, a user produces gestures without keyboards. Many experienced typists can type without looking at keyboards, and typists can make gestures, in the absence of a keyboard, that are similar to gestures that would be made if there were a keyboard. The gesture recognition system captures gestures for example, (via cameras) and interprets them as pressing an invisible keyboards, as if a keyboard were actually placed in a certain location under the typists hands. To coordinate the invisible keyboard in the correct place under the hands, the user may be provided with feedback. He or she can either view the results of the gestures via a display or hear sounds, via speakers, indicating the results of the gestures.Type: GrantFiled: June 27, 2000Date of Patent: May 9, 2006Assignee: International Business Machines CorporationInventors: Dimitri Kanevsky, Mariusz Sabath, Alexander Zlatsin
