International Classification:

H04B 14/04

US Classification:

375242

Abstract:

A multi-scale spike detector for performing multi-resolution spike detections of a signal is provided. The spike detector includes a gamma filter having cascaded low-pass filters. The cascaded filters collectively provide different cutoff frequencies, each of the filters having a respective output. One of the filters has an input, at which the signal is received. The spike detector further includes combining circuitry that combines at least some of the respective outputs of the cascaded filters. The differences formed from this combining provide a waveform representation of the input signal. The waveform representation consists essentially of spikes that occur in the signal.

Abstract:

A neural recording system () and method () for neural encoding is provided. The system can include an ultra-low power neural encoder () for compressing spikes within a neural signal () to produce a pulse train () and wirelessly transmitting the pulse train to a spike sorter (). Features of the neural signal can be encoded such that the timing between pulses and the number of pulses conveys features of the spike. The neural encoder can include an Integrate and Fire (IF) neuron that performs spike detection and encodes at least one spike () of the neural signal. A leakiness aspect () and an adaptive aspect () can be included with the IF circuit for combining aspects of spike detection and spike sorting for suppressing noise, keeping power consumption low, and improving signal resolution.

Abstract:

A system and method for dynamically protecting against security vulnerabilities in a reconfigurable signal chain. The system includes a signal chain formed from at least a first component connected with a second component. The first component has a set of source outputs and a first authentication block, and the second signal chain component has a set of destination inputs and a second authentication block. The system also includes a signal chain configurator that populates the first authentication block with at least one validated endpoint from the set of destination inputs. A signal chain integrity block, which is communicatively coupled with the first authentication block and the second authentication block, identifies a source-destination pair from one or more endpoint pairs formed from the at least one validated endpoint and the set of source outputs. The signal chain integrity block propagates the source-destination pair to the first authentication block and the second authentication block. The second authentication block authenticates any received input using the source-destination pair.

International Classification:

G01R 35/00

Abstract:

A calibrated measurement circuit, with a first node, a second node, a circuit element coupled between the first node and the second node, and a reference circuit element. The calibrated measurement circuit also comprises circuitry for directing a first current and a second current between the first node and the second node and to the reference circuit element. The calibrated measurement circuit also comprises circuitry for measuring voltage across the circuit element in response to the first and second currents, and circuitry for measuring voltage across the reference circuit element in response to the first and second currents. A calibration factor is also determined for calibrating measured voltages across the circuit element, in response to a relationship between the first voltage, the second voltage, and the reference circuit element.
