  • Patent number: 7983426
    Abstract: A method for monitoring and reporting sound pressure level exposure for a user of a first communication device (104) is implemented in one embodiment when the device measures a sound pressure level (SPL) of the surrounding environment. The device stores at least the SPL measurement in a memory, producing an SPL exposure record, and displays a visual representation of the SPL exposure record on a display screen (212). In another embodiment, the SPL is measured by a second communication device (102) and combined with a known SPL for an output audio transducer (306) of the second device, producing a user sound exposure level. The user sound exposure level is transmitted to the first communication device. The user is notified when the user sound exposure level exceeds a predetermined threshold. A server (112) may also be used to track SPLs over time and recommend corrective action when exposure limits are exceeded.

  • Publication number: 20100214111
    Abstract: A user can create “virtual graffiti” that will be left for a particular device to view as part of an augmented reality scene. The virtual graffiti will be assigned to a particular physical location or a part of an object that can be mobile. The virtual graffiti is then uploaded to a network server, along with the location and individuals who are able to view the graffiti as part of an augmented reality scene. When a device that is allowed to view the graffiti is near the location, the graffiti will be downloaded to the device and displayed as part of an augmented reality scene. To further enhance the user experience, the virtual graffiti can be dynamic, changing based on a context. For example, a user may leave a virtual graffiti message that changes with, for example, outside temperature, location, weather conditions, or any other context.

  • Patent number: 7622859
    Abstract: An electroluminescent display contains an array of dynamically addressable pixels. The pixels are arranged on one side of a carrier substrate. Conductive vias in the substrate are electrically connected to each of the pixels. Each pixel consists of a bottom electrode that is coupled to a via, an electroluminescent material, and a dielectric material. A common top electrode is disposed on the dielectric material. A driver circuit conductor or connector is situated on the other side of the substrate and is electrically coupled to each of the conductive vias and to the common top electrode, so that each pixel can be individually addressed to illuminate the electroluminescent material on individual pixels.

  • Publication number: 20090098668
    Abstract: A printing platform receives (102) (preferably in-line with a semiconductor device printing process (101)) a substrate having at least one semiconductor device printed thereon and further having a test structure printed thereon, which test structure comprises at least one printed semiconductor layer. These teachings then provide for the automatic testing (103) of the test structure with respect to at least one static (i.e., relatively unchanging) electrical characteristic metric. The static electrical characteristic metric (or metrics) of choice will likely vary with the application setting but can include, for example, a measure of electrical resistance, a measure of electrical reactance, and/or a measure of electrical continuity. Optionally (though preferably) the semiconductor device printing process itself is then adjusted (105) as a function, at least in part, of this metric.

    Abstract: A printed multilayer electronic circuit has printed electronic components on a first level circuit. Electrical conductors are printed on the first level circuit, electrically connected to the electronic components. A layer of dielectric material is printed over the printed electrical conductors. The dielectric layer contains apertures or openings that extend vertically through the dielectric layer down to the electrical conductors. A second set of electrical conductors are then printed on the dielectric layer, situated around the apertures. Electrically conductive material is printed in the apertures so that an electrical connection is made from the second set of electrical conductors to the electrical conductors on the lower level.
