Bioelectric signal detection excitation device and method

The invention discloses a bio-electricity signal detection excitation device and method, and relates to the technical field of brain-computer interfaces. The system specifically comprises an acquisition module, a main control module and an output module. A processing unit and at least two buffer units for alternately storing excitation data are configured in the main control module; when the excitation data of one buffer unit is transmitted to the output module, the processing unit synchronously writes the subsequent excitation data into the other buffer unit, and when the transmission of the previous buffer unit is completed, the other buffer unit is switched to continuously transmit the excitation data to the output module. The processing unit and the at least two buffer units for alternately storing the excitation data are configured in the main control module, and when the data of one buffer unit is independently transmitted to the output module, the processing unit synchronously calculates the detection signal and generates the excitation data, and then the excitation data is written into the subsequent data. The problems that the low-frequency waveform is distorted and the non-periodic complex waveform cannot be generated due to memory limitation of the existing equipment are solved.

  Signal processing

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B5/316, A61B5/372, A61B5/383, A61B5/386, A61B5/725). The claims define what a patent protects, and they are not read here.

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.
