Abstract: An integrated circuit device for reservoir computing can include a weighted input layer, an unweighted, asynchronous, internal recurrent neural network made up of nodes having binary weighting, and a weighted output layer. Weighting of output signals can be performed using predetermined weighted sums stored in memory. Application specific integrated circuit (ASIC) embodiments may include programmable nodes. Characteristics of the reservoir of the device can be tunable to perform rapid processing and pattern recognition of signals at relatively large rates.

Abstract: Techniques to improve the measurement of electromagnetic fields based on noise cancellation are disclosed. Sensors placed at the earth's surface measure electromagnetic fields emanating from within the earth, and/or perform electromagnetic telemetry. In one embodiment, signal processing techniques are applied to the acquired signals, either in real time or near real time to reduce or cancel the noise to enable the signal of interest to be measured. In another embodiment, the location of the plurality of sensors is judiciously chosen to improve the measurement of the signal of interest.

Abstract: An inspection system includes an electromagnetic shield having electrically conductive sidewalls spaced from one another. The shield also includes a conductive third wall which spans the distance between the sidewalls, and is electrically coupled to the sidewalls. The inspection system also has an inductive sensor positioned within the electromagnetic shield. The inductive sensor has two current branches, which exhibit anti-symmetric current flow. Typically, the two current branches are positioned on opposing sides of the medial plane of the electromagnetic shield.
