20090237412 | Data display system, data relay device, data relay method, data system, sink device, and data read method - A repeater comprises an EDID memory to store a control data and a memory control unit. The memory control unit is configured to make access to the EDID memory to read the control data therefrom, store the read control data into the EDID memory and, when access is made to the EDID memory by the set-top box, transfer the control data stored in the EDID memory to the set-top box. In this case, the memory control unit outputs an inhibiting signal to a set-top box to inhibit it from making access to the EDID memory until the completion of an operation of storing the control data from the EDID memory in the set-top box into the EDID memory in the repeater. | 2009-09-24 |

20090237414 | Storage method for gamma value look-up table - A storage method for a gamma value look-up table comprises storing gamma values corresponding to grays exceeding or equaling a 33rd gray in the gamma value look-up table, and calculating gamma values corresponding to a 1st gray to a 32nd gray by a formula. | 2009-09-24 |
20090237415 | ANTI-PHASE PULSE WIDTH MODULATOR - A method and system is disclosed for modifying the pulse width modulation signal frequency for controlling the backlight illumination intensity of a liquid crystal display. The modified pulse width modulation signal frequency is selected to eliminate visible light and dark bands in the liquid crystal display image. The brightness of the display may be also adjusted by modifying the duty cycle of the pulse width modulation signal. The brightness selected, either automatically or by the user, is matched with a pulse width modulation signal frequency to insure that the pulse width modulation signal will be anti-phased across a plurality of contiguous frame refresh periods. | 2009-09-24 |

20090237418 | USEABILITY FEATURES IN ON-LINE DELIVERY OF APPLICATIONS - Systems, methods, and computer program products for enhancing useability of on-line delivered applications. Access control is provided by generating and delivering an activation key to a client whenever the client seeks access to an application. A security process, integral to the application, validates the key. With respect to displaying information, a client inserts itself between the application and the renderer. This allows the client to provide information to the renderer for display to the user. | 2009-09-24 |
20090237419 | METHOD AND APPARATUS FOR EVOKING PERCEPTIONS OF AFFORDANCES IN VIRTUAL ENVIRONMENTS - Methods and apparatus are provided for evoking perceptions of affordances in a user/virtual environment interface. The method involves recognizing the absence or inadequacy of certain sensory stimuli in the user/virtual environment interface, and then creating sensory stimuli in the virtual environment to substitute for the recognized absent or inadequate sensory stimuli. The substitute sensory stimuli are typically communicated to the user (e.g., visually and/or audibly) as properties and behavior of objects in the virtual environment. Appropriately designed substitute sensory stimuli can evoke perceptions of affordances for the recognized absent or inadequate sensory stimuli in the user/virtual environment interface. | 2009-09-24 |
20090237420 | AUTOMATICALLY CONFORMING THE ORIENTATION OF A DISPLAY SIGNAL TO THE ROTATIONAL POSITION OF A DISPLAY DEVICE RECEIVING THE DISPLAY SIGNAL - An add-on module is described. The add-on module is comprised of an attachment mechanism, an orientation detection subsystem, and a communication subsystem. The attachment mechanism is adapted to be usable by an end user of a display device to directly attach the add-on module to the display device. The orientation detection subsystem detects the rotational orientation of the display device. The communication subsystem communicates to a video source from which the display device receives a video signal notifications of the rotational orientation of the display device detected by the orientation detection subsystem. This enables the video source to, upon receiving each notification of the rotational orientation of the display device detected by the orientation detection subsystem, conform to the notification's rotational orientation the rotational orientation of the video signal received from the video source. | 2009-09-24 |
