  • Patent number: 10834447
    Abstract: A satellite digital broadcast systems transmits signals from a geosynchronous satellite to a plurality of geographically dispersed receivers. Each receiver measures a receive signal level and transmits a value representing the level to a data center. The data center analyses data received from a plurality of receivers in order to determine a size, shape, and velocity of propagation of an obstruction. The data center then predicts which receivers will experience signal disruptions based on the obstruction and the velocity of propagation of the obstruction. The data center transmits instructions to receivers that will be affected by the obstruction.

  • Patent number: 9041929
    Abstract: An apparatus for securing a diagnostic tool proximate to and in front of a display device between the corners thereof. A harness is adapted to releasably hold the diagnostic tool, a restraining bracket extends from the harness, and there is at least one elastic cord having a first end, an intermediate portion and a second end. The cord is threaded through the restraining bracket and is sized so as to impart elastic tension to the corners of the display device while concomitantly protecting the front surface from pressure due to the position of the harness and diagnostic tool.

  • Publication number: 20150116507
    Abstract: A display enclosure with a monitoring system includes a display enclosure having an interior, a sensor positioned within the interior of the display enclosure, and a monitoring device coupled to the sensor. The interior of the display enclosure is sized and configured to receive a display device. The monitoring device includes a memory including a plurality of stored values defining a range, a processor communicatively connected to the memory, and a communication interface configured to communicate with a remote device. The processor is configured to process a signal output from the sensor indicative of a property of the interior of the display enclosure. The processor is configured to transmit a status message to the remote device via the communication interface if the property indicated by the signal is outside of the range defined by the stored values.

  • Patent number: 9001214
    Abstract: A method, system and reference target for estimating spectral data on a selected one of three spectral information types is disclosed. Spectral information types comprise illumination of a scene, spectral sensitivity of an imager imaging the scene and reflectance of a surface in the scene. The method comprises obtaining a ranking order for plural sensor responses produced by the imager, each sensor responses being produced from a reference target in the scene, obtaining, from an alternate source, data on the other two spectral information types, determining a set of constraints, the set including, for each sequential pair combination of sensor responses when taken in said ranking order, a constraint determined in dependence on the ranking and on the other two spectral information types for the respective sensor responses and, in dependence on the ranking order and on the set of constraints, determining said spectral data that optimally satisfies said constraints.

  • Publication number: 20150085143
    Abstract: Disclosed is a method and an apparatus for removing circling drifts on the display of the measured eddy current or other continuous waves. The circling dot which is supposed to be a static dot can obscure information required by the operator to judge if a small defect is present. Embodiments of presently disclosed harmonic rejection filters are tunable and employed to effectively abate or eliminate signals with frequencies that are multiples of operating frequencies, resulting in the removal of the circling effects on the display.

  • Patent number: 8976250
    Abstract: A lens testing system may have a test pattern source that generates a test pattern of light. A lens may have a lens surface that reflects the test pattern of light. A digital camera system may capture an image of the reflected test pattern of light. Computing equipment may perform image processing operations to evaluate the captured image of the reflected test pattern. The test pattern may contain a known pattern of test elements such as a rectangular array of spots or test elements of other configurations. During image processing operations, the computing equipment may analyze the reflected version of the spots or other test elements to measure characteristics of the lens such as radius of curvature, whether the lens contains flat regions, pits, or bumps, lens placement in a support structure, and other lens performance data. The computing equipment may compare the measured lens data to predetermined criteria.
