Abstract: A "Barometer" Neuron enhances stability in a Neural Network System that, when used as a track-while-scan system, assigns sensor plots to predicted track positions in a plot/track association situation. The "Barometer" Neuron functions as a bench-mark or reference system node that equates a superimposed plot and track to a zero distance as a "perfect" pairing of plot and track which has a measured/desired level of inhibition. The "Barometer" Neuron responds to the System inputs, compares these inputs against the level of inhibition of the "perfect" pair, and generates a supplied excitation or inhibition output signal to the System which adjusts the System to a desired value at or near 1.0; this the reference level of inhibition of the "perfect" pair.

Abstract: A reflective magneto-optic spatial light modulator (MOSLM.TM.) assembly has a nonmagnetic protective housing that receives, positions, and protects a spatial light modulator (SLM) chip that is formed from relatively fragile magneto-optic material from deformations caused by mechanical stress and by excessive temperature changes. The assembly further has a channelled ingress and egress of incident electromagnetic radiation, such as visible and coherent light, to and from the SLM chip.

Abstract: A split core degaussing coil loop having a segmented and disassembled loop portion that is joined together to include an object to be demagnetized, in situ, as part of the assembled core loop and further having an inductor coil assembled with the loop that is selectively energized in one or more steps from a source of electrical power which generates a demagnetizing force directed to the object.

Abstract: The invention is a connector to join structural members.In particular, the invention is a connector to assemble and join structural members where the members can be formed from dissimilar materials; for example, an aluminum plate joined by the connector to a steel plate. The connector can be formed in part or in whole from a shape memory metal that exhibits dimensional change upon assembly to complete the joint.

Abstract: The self-locking chock system has a plurality of pawl cams grouped in a sequential alignment along a support member that is substantially parallel with a leg rack of a jack-up rig unit. Each of the cams is pivoted about a pivot axis that is on the common alignment axis of the support member, and is forced to ride upon the leg rack by a center of gravity located outwardly from the alignment axis on the side opposite that which rides on the leg rack. The cam profile is adapted to ride along the leg rack profile when the relative motion between the leg rack and the support member is in a first direction. When the relative motion is in a direction opposite to the first direction, the cam profile complements the leg-rack profile and under the weighted urging of the cam, the cam profile engages the leg-rack profile and enters into a positive, self-locking engagement that restrains further relative motion between the leg rack and the support member at least in the opposite direction.
