20100315427 | MULTIPLE GRAPHICS PROCESSING UNIT DISPLAY SYNCHRONIZATION SYSTEM AND METHOD - Systems and methods for utilizing multiple graphics processing units for controlling presentations on a display are presented. In one embodiment, a dual graphics processing system includes a first graphics processing unit for processing graphics information; a second graphics processing unit for processing graphics information; a component for synchronizing transmission of display component information from the first graphics processing unit and the second graphics processing unit and a component for controlling switching between said first graphics processing unit and said second graphics processing unit. In one embodiment, the component for synchronizing transmission of display component information adjusts (e.g., delays, speeds up, etc.) the occurrence or duration of a corresponding graphics presentation characteristic (e.g., end of frame, end of line, vertical blanking period, horizontal blanking period, etc.) in signals from multiple graphics processing units. | 12-16-2010 |
20120206461 | METHOD AND APPARATUS FOR CONTROLLING A SELF-REFRESHING DISPLAY DEVICE COUPLED TO A GRAPHICS CONTROLLER - A method and apparatus for controlling a self-refreshing display device coupled to a graphics controller are disclosed. A self-refreshing display device has a capability to drive the display based on video signals generated from a local frame buffer in the display device. A graphics controller coupled to the display device may optimally be placed in one or more power saving states when the display device is operating in a panel self-refresh mode. The graphics controller detects one or more progressive levels of idleness in the graphics controller and the pixel data stored in a frame buffer. Based on the detected idleness, the graphics controller signals the display device to enter or exit the panel self-refresh mode and enters a power saving state. When exiting the panel self-refresh mode, the display device and/or graphics controller ensure that the video signals generated by the local controller and the graphics controller are aligned. | 08-16-2012 |
20130235048 | SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT FOR ADJUSTING A REFRESH RATE OF A DISPLAY - A display refresh system, method and computer program product are provided. In use, at least one aspect of a display of content is identified by monitoring commands. Based on such identified aspect(s), a refresh rate of a display utilized for the display of the content may be adjusted. | 09-12-2013 |
20160047887 | BLUETOOTH CROWD-SOURCED TRIANGULATION - Beacon devices transmit beacon messages to alert an application on a mobile user device of the Beacon device's proximity. A Received Signal Strength Indication (RSSI) field may indicate the power level at which the beacon message was received at the mobile device. Where the transmission power of the beacon device is standardized, the application can infer the distance between the mobile user device the beacon device based upon the RSSI field. By considering successive RSSI values over time while the mobile device is in motion, in conjunction with GPS information for the mobile device, the location of the beacon device relative to the mobile device may be inferred. Multiple mobile devices may be used together to infer the beacon device's position. | 02-18-2016 |
20160050219 | BLUETOOTH BEACON PROTOCOL - Beacon devices may transmit beacon messages to alert an application on a mobile phone of the beacon device's proximity. An encrypted authorization may be used to prevent malicious attacks. Unfortunately, some operating systems, e.g., the iOS™ operating system, strip data fields in service Universally Unique Identifiers (UUIDs) from a received beacon message before the message is passed to the application. Various embodiments provide a protocol wherein the beacon device successively transmits a first beacon message (e.g., an iBeacon™ message) and a second Bluetooth® Low Energy broadcast message. The first beacon message alerts the application of the beacon device's proximity and identity while the second message contains the encrypted authorization and possibly any additional information relevant to the application. | 02-18-2016 |
20160050564 | BLUETOOTH TRANSMISSION SECURITY PATTERN - Beacon devices transmit beacon messages that may be used to alert an application on a user device, e.g., a mobile phone, of the beacon device's proximity. Some embodiments contemplate a beacon device configured to transmit a pattern of successive beacon messages and/or Bluetooth Low Energy broadcast messages at one or more different power levels. The pattern of power levels may securely identify the beacon device. For example, the mobile phone application may confirm with a network server that the pattern agrees with the beacon device's identity. The pattern may also serve a calibration function. Where the mobile device application has knowledge of the expected power levels in the pattern, the application can infer from weaker transmissions that the beacon device is further from the mobile device. The weaker power levels may also indicate the character of the transmission environment. | 02-18-2016 |
