The method also includes assigning a synapse from each symbol neuron in a group to a particular ngram neuron. A set of synapses associated with the group of symbol neurons comprises a bundle of synapses. In addition, the method includes assigning a delay to each synapse in the bundle. The method further includes representing a symbol sequence based on sequential spiking of symbol neurons and ngram neuron spikes in response to detecting inter event intervals. | 10-01-2015 |

20100266276 | BROADBAND AND WAVELENGTH-SELECTIVE BIDIRECTIONAL 3-WAY OPTICAL SPLITTER - Embodiments of a bidirectional 3-way optical splitter are described. This bidirectional 3-way optical splitter includes an optical splitter having: a first external node, a second external node, a third external node, and a fourth external node. In one mode of operation, the optical splitter may be configured to receive an external input optical signal on the first external node and to provide external output optical signals on the other external nodes. Moreover, in another mode of operation, the optical splitter may be configured to receive the external input optical signal on the third external node and to provide the external output optical signals on the other external nodes. | 10-21-2010 |
20120230695 | WAVELENGTH-DIVISION MULTIPLEXING FOR USE IN MULTI-CHIP SYSTEMS - Embodiments of a system that includes an array of chip modules (CMs) is described. In this system, a given CM in the array includes a semiconductor die that is configured to communicate data signals with one or more adjacent CMs through electromagnetic proximity communication using proximity connectors. Note that the proximity connectors are proximate to a surface of the semiconductor die. Moreover, the given CM is configured to communicate optical signals with other CMs through an optical signal path using optical communication, and the optical signals are encoded using wavelength-division multiplexing (WDM). | 09-13-2012 |
