Patent number: 8898366Abstract: An apparatus and method is disclosed for providing an extensible information handling system (IHS) bus implemented on predetermined channels of a digital video interface. IHS video signal information is multiplexed with IHS bus information by a host multiplexer for transmission across a digital video connector. The multiplexed IHS video signal and IHS bus information is received by a display multiplexer, where it is demultiplexed. Demultiplexed IHS video signal information is received by a video interface receiver, where it is used to generate an image on a digital display. Demultiplexed IHS bus information is received by a host bus interface transmitter/receiver, where it is used to support peripheral devices attached to the digital display.Type: GrantFiled: November 20, 2012Date of Patent: November 25, 2014Assignee: Dell Products L.P.Inventors: Joseph Edgar Goodart, Shuguang Wu

Publication number: 20140139420Abstract: A system for human interaction based upon intention detection. The system includes a sensor for providing information relating to a posture of a person detected by the sensor, a processor, and a display device. The processor is configured to receive the information from the sensor and process the received information in order to determine if an event occurred. This processing includes determining whether the posture of the person indicates a particular intention, such as attempting to take a photo. If the event occurred, the processor is configured to provide an interaction with the person via the display device such as displaying a message or the address of a web site.Type: ApplicationFiled: November 20, 2012Publication date: May 22, 2014Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: SHUGUANG WU, JUN XIAO, GLENN E.

Publication number: 20140085432Abstract: A method of reducing crosstalk for a 3D stereoscopic display using locally stored crosstalk profiles. The method generates a crosstalk profile for a stereoscopic display and stores the crosstalk profile in a memory, such as the EDID or DID, locally associated with the display. The crosstalk profile includes information for reducing crosstalk in the display based at least in part upon operational characteristics of the display. The method retrieves the crosstalk profile and applies the information in the crosstalk profile to stereoscopic content displayed on the display in order to reduce crosstalk in the displayed content. Using a locally stored crosstalk profile provides for crosstalk reduction tailored to a specific display.Type: ApplicationFiled: September 27, 2012Publication date: March 27, 2014Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: Shuguang Wu, Glenn E.

Publication number: 20140062710Abstract: A method of aiding viewing position for autostereoscopic displays having a suggested viewing zone or optimal viewing position. The method detects a position of a viewer using a detection sensor associated with the display and determines if the viewer is within the suggested viewing zone. If the viewer is not within the suggested viewing zone, the method provides feedback to the viewer, such as visual cues on the display, indicating how the viewer should move in order to be within the suggested viewing zone. The method can continuously provide the feedback in order to indicate how the viewer is moving with respect to the suggested viewing zone and when the viewer has moved into the suggested viewing zone.Type: ApplicationFiled: August 29, 2012Publication date: March 6, 2014Inventors: Shuguang Wu, Jun Xiao

Patent number: 7401243Abstract: A variable speed data processor includes a clock generator generating a plurality of clocks at different clock rates. Clock select circuitry synchronously selects one of the clocks as an output clock signal to data processing circuitry, based on a data activity indication. Activity logic generates the data activity indication based at least in part on the existence of data processing activity targeted to the data processing circuitry. When the data processing circuitry experiences bursty data processing activity, the clock rate can shift rapidly between the multiple clock rates, conserving power without substantially diminishing the availability of the data processing circuitry.Type: GrantFiled: June 21, 2005Date of Patent: July 15, 2008Assignee: Dell Products L.P.Inventors: Lawrence Edward Knepper, Shuguang Wu

Patent number: 7310099Abstract: A method for detecting an inappropriate video connection in an information handling system (“IHS”) that includes an integrated video controller, the integrated video controller operable to be coupled to a display device, is provided. The method includes determining if an add-in video controller is coupled to the IHS, the add-in video controller operable to be coupled to the display device. The method also includes determining whether the display device is coupled to the integrated video controller or the add-in video controller. The method further includes providing a notification that the display device is inappropriately coupled to the IHS if it was determined that both the add-in video controller is coupled to the IHS and the display device is coupled to the integrated video controller.Type: GrantFiled: May 3, 2004Date of Patent: December 18, 2007Assignee: Dell Products L.P.Inventors: Shuguang Wu, Faisal Awan, Orlando Rigueira, Aaron Taylor
