    Abstract: The detection of low energy neutrons is improved using a capture material (12) which reacts to incident particles or electromagnetic energy by emitting radiation which is more easily detected by a conventional solid state detection device (10).

    Abstract: The comparators described herein comprise bit manipulation cells of a number of logic cells each built up of AND, OR etc. logic gates interconnected in parallel to make up one or more layers and do not rely on clocks, instead operating asynchronously. This makes the comparators highly robust and fault tolerant, and well suited for use as binary neurons in high integrity systems. They are less susceptible to radio frequency interference induced data corruption than alternative register-based implementations. Planar Hamming comparators capable of comparing two dimensional input arrays are also described.

    Abstract: A neural pattern matcher is made up of an array of first sum and threshold SAT1 devices 18 each of which receives a number of inputs and a threshold value, and fires a 1 output if the number of inputs exceeds the threshold value. The outputs of the array of the SAT1 devices may be considered as a 2D image or generic template against which new data supplied into the registers 26 making up a data plane 24 are correlated at a correlation plane 20 of EX-NOR gates 22. The outputs of the EX-NOR gates themselves may be summed and thresholded by a seconded sum and threshold device 28 to provide a neural output '1' or '0' indicating match or no match. The matcher may therefore behave as a neural auto-associative memory which continually adapts to the input data to recognize data of a particular specified class.

    Abstract: Apparatus and methods are disclosed for treating an input set of weightless binary tuples to order the Hamming values thereof. In the general case, the tuples are thermometer coded in a common direction (left or right) and thereafter an orthogonal thermocoding operation is applied in which orthogonal tuples, each taking a bit from a respective bit position of the thermocoded tuples, is subjected to a thermocoding operation in a common direction (up or down). At the completion of this operation the tuples represent the Hamming values of the input tuples, ranked in Hamming value order. The first thermocoding operation may be omitted where the input tuples are already in thermometer code. Also described is a scheme, which uses a tagging procedure to give the result in terms of the original weightless binary tuples, whereby the input pattern information is preserved.
