Abstract: Reconfigurable virtual backplane systems and methods are provided. One virtual backplane system includes a bus, and first and second line cards coupled to the bus. Each line card includes a processor including a memory storing an array of configuration tables. Each configuration table stores a listing of processes to be transmitted to or received from the communication bus, wherein a first configuration table is selected from the first line card upon the occurrence of a first event and a second configuration table is selected from the second line card upon the occurrence of a second event. One method includes connecting first and second buses in first and second systems, respectively, to form a bus for a new system. The method further includes detecting the connection of the first and second buses, and reconfiguring the first and second systems to operate as the new system in response to detecting the connection.

Abstract: Methods and systems verify and control the quality of metadata associated with a media data file. The metadata may be used, for example, by media content recommendation systems. In one embodiment, a first attribute is selected from metadata associated with a media data file and an attribute dependency corresponding to the first attribute is determined. The metadata may be searched to determine whether it includes a second attribute that satisfies the dependency. If the dependency is not satisfied, the metadata is flagged for reevaluation. The metadata may also be flagged for reevaluation, for example, if the metadata includes inconsistent attributes, if the total number of assigned attributes within the metadata does not exceed a predetermined value, or if an expected attribute dimension is missing or does not include an expected number of defined attributes. In certain embodiments, user selections are controlled to provide consistent attribute combinations.

Abstract: Processor assemblies and modules are provided. One processor assembly includes first and second processors, and first and second input/output (I/O) interfaces coupled to the first and second processors. The first and/or second I/O interfaces are configured to compare outputs of the first and second processors, and render the first and second processors inactive if the outputs are different. One processor module includes first and second buses coupled to first and second processor assemblies. The first processor assembly includes first and second processors coupled to first and second I/O interfaces, wherein the first I/O interface is coupled to the first bus and the second I/O interface is coupled to the second bus. The second processor assembly includes third and fourth processors coupled to third and fourth I/O interfaces, wherein the third I/O interface is coupled to the first bus and the fourth I/O interface is coupled to the second bus.

Abstract: Systems and techniques for product identification using terahertz radiation detection. An area of interest is illuminated with radiation in the terahertz frequency range and terahertz radiation reflected from objects within the area of interest is detected and a detector signal based on the detected radiation is processed to generate identifying information for the objects. The generated identifying information may be compared against stored identifying information for products and the result of the comparison is used to select a product or group of products for which the comparison produces a match. Processing of the detector signal may generate a spectral signature characteristic of reflective and absorptive properties of an object under illumination, and the spectral signature may be compared with stored spectral signature information for products.

Abstract: Methods and systems generate deep metadata associated with media content. The deep metadata may be used, for example, by media content recommendation systems. In one embodiment, a database includes a plurality of media files that are each associated with respective data models and metadata sets. A new media file is categorized by microgenre and automatically analyzed to generate a new data model. The new data model is compared to the database to determine a particular data model stored therein that satisfies a similarity threshold. In one embodiment, the comparison is limited to data models that are associated with the same microgenre as that of the new media file. A set of metadata associated with the particular data model stored in the database is then assigned to the new media file. In an example embodiment, the new media file is an audio file and the database is a music database.

Abstract: A light controller capable of varying the brightness of a light emitting diode in a linear manner. The light controller may control a number of lights in a predetermined pattern or in a pattern designed by the user. A remote control may be used to control and interact with the light controller. The light controller may have inputs for audio signals, tachometer signals, or other external signals. The light controller may be coupled to other light controllers to enable the control of additional lights in a synchronized manner. The light controller may be particularly well suited to controlling light emitting diodes and controlling lights in a vehicle accent lighting application, although many other uses may be apparent.

Abstract: An EIT system includes a plurality of voltage sources for supplying a corresponding plurality of voltages to a corresponding number of other structures, voltage source calibration means for calibrating each voltage source, and switching means for individually connecting the calibration means to each voltage source in succession during a period when each other structure is in an inactive condition. Calibrating respective voltages and currents for each voltage source compensates for shunt impedance of each voltage source. A method for calibrating the system includes individually connecting the calibration means to each voltage source in succession during a period when each other structure is in an inactive condition for calibrating all of said voltage sources in the same way.
