摘要： An optical device includes a 50-50 cross-coupler having a pair of ports optically coupled by a waveguide which includes a portion of material having a non-linear refractive index with a relaxation time such that the effect on the non-linear portion of a first pulse passing through the portion last long enough to affect the phase of a second pulse relative to the first. It finds application as a logic element, optical amplifier modulator and the like.

摘要： A radiation generator in which substantially all the radiation modes are locked with respect to one another comprises a radiation generating cavity defined by mirrors and a crystal for generating a continuous train of non-transform limited pulses of coherent radiation. An external cavity is positioned in association with the radiation generating cavity whereby radiation may pass in use in both directions between the two cavities. The external cavity is defined by a medium having a non-linear transmission characteristic which may be substantially non-dispersive for radiation from the generating cavity, and/or which has a negative group delay dispersion. The radiation path length is such that pulses fed into the external cavity are fed back to the radiation generating cavity in synchronism with a later pulse from the generating cavity.

摘要： A neural network has inputs formed by square array of optical modulators M.sub.ij and outputs by optical detectors D.sub.ij coupled to threshold comparators. A holographic plate includes a spatial modulator whose elements are controlled by a controller to form an array of optical beams from a coherent optical source. Each optical beam optically interconnects a modulator M.sub.ij with a respective detector D.sub.ij. The weight values of the neural network are provided by the intensities of the optical beams. This obviates the need for an optical weighting mask between an array of light emitting diodes and a detector array allowing a higher density of lower power consumption components and reprogrammability of the network.

摘要： A spindle nut and a locking device for securing the nut in a rotative position on a spindle. An anti-rotation spring and a back up plate are mounted on the spindle in a non-rotative manner with the back up plate in abutment with the bearings that rotatively mount the hub to the spindle. The back up plate has multiple grooves aligned with and arranged to receive multiple resilient tabs on the periphery of the anti-rotation spring. The tabs of the anti-rotation spring are formed to project axially from the spring. A flange of the nut has multiple slots around its periphery that are sized to receive a tab of the anti-rotation spring. A tool having extending ears that fit in the slots of the nut is utilized to install the nut on the spindle. The extending ears prevent the tabs of the spring from entering a slot of the nut until the tool is removed. As the nut is rotated by the tool, the nut abuts the anti-rotation spring. The extending ears and the face of the flange in combination force the radial tabs of the spring further into the grooves of the back up plate. When the nut is torqued to the desired level, the tool is removed allowing a tab of the spring to enter a slot of the nut due to its resiliency to lock the nut in a rotative position. Should a tab of the spring not be in alignment with a slot of the nut, the nut need only rotate a few degrees to place one of the slots of the nut in alignment with a tab of the spring.

摘要： A method of training a neural network (2) having dynamically adjustable parameters controlled by a controller (10) which determine the response of the network (2). A set of input vectors (I.sub.l to I.sub.n) are input to network (2) at an input port (4). The corresponding set of output vectors (O'.sub.l to O'.sub.n) provided by the network (2) are compared to a target set of output vectors (O.sub.l to O.sub.n) by an error logger (12) which provides to the controller (10) a measure of similarity of the two sets. The controller (10) is arranged to alter the dynamic parameters independence on the average number of occasions the output vectors are different from the respective target output vectors. Measuring the similarity of the whole of the output set and target set and adjusting the parameters on this global measure rather than on the similarity of pairs of individual vectors provides enhanced training rates for neural networks having a data throughput rate that can be higher than the rate at which the parameters can be adjusted.
