  • Patent number: 8989683
    Abstract: Techniques and architecture are disclosed for providing an ultra-wideband, multi-channel solid-state power amplifier architecture. In some embodiments, the architecture includes a power divider which splits an input signal and delivers that split signal to a plurality of downstream channel chipsets. Each channel chipset is configured to amplify a sub-band of the original full-band input signal and to provide the resultant amplified sub-band for downstream use, such as for transmission by an antenna operatively coupled with that channel. In the aggregate, the amplified sub-bands provide coverage of the same ultra-wideband frequency range of the original input signal, in some cases. In some embodiments, the architecture provides high radio frequency (RF) power with good amplifying efficiency and ultra-wide instantaneous frequency bandwidth performance in a small-form-factor package.

  • Patent number: 8977744
    Abstract: A hardware device for monitoring and intercepting data packetized data traffic at full line rate, is proved. In high bandwidth embodiments, full line rate corresponds to rates that exceed 100 Mbytes/s and in some cases 1000 Mbytes/s. Monitoring and intercepting software, alone, is not able to operate on such volumes of data in real-time. An exemplary embodiment comprises: a data delay buffer with multiple delay outputs; a search engine logic for implementing a set of basic search tools that operate in real-time on the data traffic; a programmable gate array; an interface for passing data quickly to software sub-systems; and control means for implementing software control of the operation of the search tools. The programmable gate array inserts the data packets into the delay buffer, extracts them for searching at the delay outputs and formats and schedules the operation of the search engine logic.

  • Patent number: 8976728
    Abstract: Message or traffic data is transmitted from a given radio or node for reception by one or more other nodes in a communications network, by arranging the node for transmitting the data according to a selected one of a number of different medium access protocols. The medium access protocol selected for a given message or traffic is determined according to one or more of (a) the size of the traffic, (b) the priority of the traffic, (c) the periodicity of the traffic, and (d) whether the traffic is broadcast or unicast to the other nodes in the network. Each radio includes one or more processor and memory modules configured to output messages or traffic for transmission from the radio according to the selected medium access protocol. By using distributed scheduling and traffic control to protect against hidden nodes, the radios can maintain agile portability in tactical urban environments.

  • Patent number: 8977002
    Abstract: A method of point source target detection for multispectral imaging is disclosed. In one embodiment, a background source spectral ratio is determined using at least one radiant source, such as baseline intensities, camera optics sensitivity properties and atmospheric transmission properties. Further, a spectral difference is computed for each pixel in an incoming frame by applying the background source spectral ratio to a spectral band-specific radiant intensity value of each pixel. Furthermore, offset biasing in the incoming frame is removed by applying spatial median filtering to each computed spectral difference in the incoming frame.
