    摘要： Various techniques are described for resource management on a computing platform. A computing platform can receive a query message that specifies an amount of a resource proposed for allocation. The computing platform can select a selected recommendation level from a plurality of recommendation levels, based on an evaluation of a request for the amount of the resource proposed for allocation. The computing platform can generate a resource allocation recommendation that includes the selected recommendation level with respect to the amount of the resource proposed for allocation. The computing platform can send the resource allocation recommendation.

    摘要： Video components attributable to ambient lighting in a stream of digital images of a scene illuminated by both ambient and active sources are eliminated in each image frame, leaving only video components attributable to the active source. The spectrum of the active source is encompassed by the ambient source, and spectral filtering defines a primary channel comprising video components in a primary spectrum encompassing both active and ambient lighting and a secondary channel comprising video components in a secondary spectrum encompassing only ambient lighting. The pixels of the secondary channel are scaled by a factor correlating the spectral reflectances of the primary and secondary spectra, and the scaled secondary channel is subtracted from the primary channel to produce an ambient corrected image. The pixels of the ambient corrected image are further scaled to compensate for spectral filter bleeding of the active source into the secondary channel.

    摘要： A monitoring system for an RF transmission system, such as a multi-channel television broadcasting antenna feed system, gathers data about the physical and electrical condition of the RF transmission system in real time. The system can detect and localize deterioration and other time-dependent faults in the transmission system by the tendency of faults to produce reflections back to the transmitter that were not part of the original characterization of the installation. Some kinds of faults, identified early enough, can be corrected without replacing components, and especially without shutting down the transmission system during prime viewing hours in the case of television broadcasters, or during a critical period of use of the system in the case of other user types. Other faults can be detected in time to order replacement parts before the underlying problem becomes severe, and to allow servicing during periods of low demand.

    摘要： A dual-port IBOC® antenna provides omnidirectional radiation of orthogonal, circularly polarized analog (FM) and digital (OFDM) signals using quadruple coplanar square loops driven from a hybrid having balanced outputs. The loops are arranged in a tiled square, with proximal sides functioning as further stripline hybrids to cancel cross coupling between the loops. Each loop quad is reflector-backed and emits a directional signal; multiple loop quads oriented radially form an omni bay. Vertical spacing between bays includes a minimum position for mutual coupling, while symmetry establishes uniform input impedance on the hybrid input ports. Tuning barbs on the loops fine tune frequency response. Bandwidth is wide, so that a single antenna can radiate multiple FM analog and hybrid IBOC® channels over the VHF FM radio broadcast band.
