Abstract: Systems and methods for electronic access control for secured assets including locked facilities, lockers, shared vehicles and vending machines, which do not have internet connectivity. A mobile device communicates with a server to perform the authentication and access control steps, limiting the asset's interactions with outside devices to exchanging and updating access codes via short-range communications, such as near-field communications. Authentication and access control steps may be performed when the mobile device is at the secured asset, or alternatively those steps may be performed in advance, to allow access to assets located outside of data service to the mobile device.

Abstract: 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.

The display and information handling system communicate through the auxiliary channel to coordinate power transfer from the display to the information handling system, such as in the form of a trickle charge to a battery integrated in the information handling system.

Abstract: A system for augmenting displayed content with embedded invisible information such as visual or audio information, or a network link to the augmented information. The system includes a display module, first and second backlight modules, and a controller. The first and second backlight modules selectively provide visible light and invisible light, such as infrared light, to the display module. The controller provides first and second frames of content, alternating in a time sequential manner, to the display module with the first frames of content backlit by the first backlight module and the second frames of content backlit by only the second backlight module. The second frames of content provide invisible information embedded with the first frames of content and can be detected an infrared camera and used to display or provide augmented information.

Abstract: 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.
