System and methods for processing neural signals

Systems and methods for processing neural signals are provided. A neural data analysis system may comprise a feature extraction module configured to (1) extract a plurality of features from neural signal waveforms obtained by an implanted neural interface probe with a plurality of channels or electrodes, wherein the plurality of features are extracted from the neural signal waveforms without requiring prior digitization of the neural signal waveforms, and (2) to transmit the extracted features as a plurality of discrete outputs. The neural data analysis system may also comprise a feature-event coalescence module configured to: (1) receive the plurality of discrete outputs from the feature extraction module, and (2) construct a model-based inference of bioelectric activity based on feature-event statistics, prior knowledge of bioelectric signals, and/or a behavioral model of the feature-extraction module. The neural data analysis system may further comprise an approximator module configured to (1) receive a plurality of coalesced events from the feature-event coalescence module, and (2) apply a series of transformations to the coalesced event data to generate a higher entropy neural code, wherein the neural code comprises a representation of ensemble activity of a plurality of neurons recorded by the system.

  Signal processing

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B2560/0209, A61B5/374, A61B5/389, A61B5/4064, A61B5/6868). The claims define what a patent protects, and they are not read here.

Interface and electrodes

Everything downstream works with what the contacts pick up. Their number, size and distance from the neurons set the ceiling on the signal. The problem behind it: more contacts, closer to neurons, that still record after years in tissue that reacts to them.

Signal processing

A decoder is only as good as the features it is given, and recordings drift and pick up noise from movement, muscle and stimulation. The problem behind it: stable features from signals that change from day to day, computed fast enough to act on.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack

Dates as the offices published them. Office records are in the offices' own words and are a selection: refusals, lapses and withdrawals, and records that name an owner. Each concerns one member of the family, not the family as a whole, and another member in the same office may stand. Whether a patent is in force today is not assessed.
