Single-device multi-physiological parameter synchronization method, acquisition system and data alignment method

The invention relates to the technical field of biological information, in particular to a single-device multi-physiological-parameter synchronization method, a single-device multi-physiological-parameter acquisition system and a single-device multi-physiological-parameter data alignment method, and the single-device multi-physiological-parameter synchronization and fusion method comprises the following steps: S1, constructing a one-to-one wireless transmission system; s2, constructing a one-to-many wired transmission system; s3, initiating a synchronization instruction; s4, verifying the information; and S5, matching the information to align the first acquisition data packet of the sensor module. According to the invention, the acquisition master control module sends the synchronization information to the plurality of sensor modules at the same time, the acquisition master control module carries out time mapping on the acquisition data packets sent by the plurality of sensor modules through a plurality of pieces of timestamp information, and the plurality of sensor modules do not need to be connected in series by adopting the same clock source, so that the sensor type selection is not limited, and the cost is reduced. And the sampling rate can be adjusted in real time, and high synchronization efficiency among the plurality of sensor modules is ensured.

  Signal processing

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B5/7275, G06F1/12, G06F16/27, G06F18/25, Y02D30/70). The claims define what a patent protects, and they are not read here.

Signal acquisition

Neural signals are microvolts. They have to be amplified and digitised on many channels at once, inside a power budget that must not warm the tissue. The problem behind it: low noise on hundreds or thousands of channels at milliwatts.

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.
