  • Distributed Sensor Signaling | TechLink
    environment Multiple sensors can be used to capture the signal of interest SOI when the signal is weak An approach to minimize the investment in the sensor network is to deploy massive amounts of very low cost and disposable sensors to cover a large territory or leverage all existing infrastructure in the area such as radios wifi devices phones or mesh networks The burden of the signal processing of raw data is pushed towards a central fusion center There is therefore a need for a new method for optimal signal combining Image Right Distributed Signal Sensing The Technology The US Army R D lab has developed and patented a post synchronization and classification method for aggregating and processing the raw data from the distributed sensor network The method utilizes higher order statistics of distributed signals to give a more robust and accurate estimation and classification of the signal of interest Efficient signal processing algorithms implemented in a fully distributed manner minimize the local processing and make the pervasive network sensing and classification possible Benefits Low Investment Leverage the low cost or existing communications devices Precision Monitoring Operate in complex noisy real world real time environments Scalable Future system upgrades are

  • Efficient Hexagonally Sampled Image Processing | TechLink
    image processing systems This is arguably due to the lack of an efficient addressing system for hexagonal grids A new method for addressing hexagonally arranged image sensors that produces an output that can be efficiently computationally manipulated particularly in digital systems has been developed by a US Air Force R D lab The patented invention called array set addressing or ASA solves the problems for any hexagonally arranged data sampling elements A primary concept behind ASA is that a hexagonal grid can be represented as a set of two rectangular arrays distinguished by a single binary coordinate What s particularly new in the present invention is extending that concept and applying it to addressing captured information from a hexagonal grid of image sensor pixels The hexagonal grid has greater angular resolution equidistant spacing and a higher degree of symmetry than rectangular grids Also since all neighboring pixels in a hexagonal grid share a side there is no connectivity ambiguity as there is with rectangular grids which leads to more efficient algorithms that deal with connectivity Benefits Broad Imaging Applications Hexagonal sampling works in all frequency bands Less Computational Burden Faster computational operations for hexagonal sampled images Elegant Solution ASA significantly
