Abstract: Applicants have produced a chromophore and a polymer that are highly sensitive to the presence of various agents, including organophosphates, pesticides, neurotoxins, metal ions, some explosives, and biological toxins. The detection is accomplished by detecting a change in the fluorescence characteristics of the chromophore or polymer when in the presence of the agent to be detected. The chromophore and polymer may be incorporated into sensors of various types, and they are adaptable for potential field use in areas where detection of these types of agents is desired.

Abstract: An apparatus for controlling light emission and/or sensing in an array of optical elements. An infra-extensible array having a plurality of subarray display circuits interconnected with neighboring subarray display circuits. Each subarray display circuit is configured with a processor and a plurality of output and/or input elements. Messages and instructions can be propagated from one subarray display circuit to another to provide local processing relating to input and output elements, such as changing the pixels in the display from a subarray display circuit in response to locally sensed conditions or those communicated from neighboring subarray display circuits. Apparatus is infra-extensible as both the number of processors for executing display/sensor programming, and the number of communication channels available through which instructions can be received, increases automatically in response to increasing the number of subarray display circuits within the apparatus.

Abstract: An apparatus and method controlling cellular automata containing a plurality of cascaded circuit cells having logic units. The cells are interleaved in groups toward supporting multiple directions, for example quad cells in which each cells of the quad is directed in a different directions separated by a fixed angle, such as 90 degrees (i.e., north, east, south, and west). These cells are triggered asynchronously as each cell is stabilized in preparation for receiving the trigger. The cells process data selectively based on the configuration of the cell and in response to receipt of data and trigger (or combined data and trigger) conditions from neighboring cells. The array can be utilized within a wide range of digital logic. As there is no need for distributing a global clock across the array of cells, the size of the array can be extended to any desired dimension.

The set of binary data is arranged in the data storage such that the binary data is in bit position groups. Each bit position group corresponds to a different one of the plurality of bit positions and includes bits of the binary data having that bit position. The binary data of each bit position group is compressed to produce data structures representing the set of binary data. A data mining technique is performed using the plurality of compressed data structures.
