Abstract: A fault circuit indicator (FCI) detection system for electrical equipment disposed in an enclosure or vault having an above-ground vent pipe exhaust outlet comprises one or more sensors disposed in the enclosure or vault to sense a condition of at least one unit of the electrical equipment. A sensored analytics unit (SAU) is coupled to the sensors to receive sensor data and analyze the sensor data, the SAU generating a corresponding analyzed data signal that provides information related to a condition of the at least one unit of electrical equipment. A transceiver is disposed inside at least a portion of the vent pipe to receive the analyzed data signal, wherein the transceiver is configured to communicate the analyzed data signal. A visual indicator is disposed on or within the vent pipe comprising one or more visual indicators, such as LEDs, driven by a driving circuit board to provide a visual signal corresponding to the condition of the at least one unit of electrical equipment.

Abstract: 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.

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: 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 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.
