    摘要： According to a technique, an electronic device is configured to correspond to characteristic features of a biological synapse. The electronic device includes multiple bipolar resistors arranged in parallel to form an electronic synapse, an axonal connection connected to one end of the electronic synapse and to a first electronic neuron, and a dendritic connection connected to another end of the electronic synapse and to a second electronic neuron. An increase and decrease of synaptic conduction in the electronic synapse is based on a probability of switching the plurality of bipolar resistors between a low resistance state and a high resistance state.

    摘要： A system, method, and design structure for address-event-representation network simulation are provided. The system includes a hardware structure with a plurality of interconnected processing modules configured to simulate a plurality of interconnected nodes. To simulate each node, the hardware structure includes a source table configured to receive an input message and identify a weight associated with a source of the input message. The hardware structure also includes state management logic configured to update a node state as a function of the identified weight, and generate an output signal responsive to the updated node state. The hardware structure further includes a target table configured to generate an output message in response to the output signal, identify a target to receive the output message, and transmit the output message. The hardware structure may further include learning logic configured to combine information about input messages and generated output signals, and to update weights.

    摘要： A method for making an optical fiber transmission apparatus for limiting the optical modes which were emitted from a source in such a way to impinge on an optical fiber to extract a high bandwidth from the fiber. The apparatus includes a lens or aperture to control the angle and distribution of light launched into the fiber. The apparatus achieves reproducibly high bandwidths in large core step-index optical fibers of short transmission length distances. The lens or aperture introduces light from the source into the fiber at an angle at which substantially no intermode delay occurs as the light propagates down the fiber. An integral fiber optic coupling assembly that includes an optical electronic component receptacle, the lens and/or aperture, and an optical fiber connector interface which provides low cost easy to manufacture assembly is also disclosed. A unitary plastic housing provides the function of a lens and mechanical reference or locating features for the light source and optical fiber.
