  • Publication number: 20220218261
    Abstract: A method for processing time series data comprises: dividing time series data into a plurality of data fragments according to an objective function, the plurality of data fragments having a greatest similarity; in response to determining that at least one data fragment does not satisfy an iteration termination condition, performing following iteration operations on the at least one data fragment; and constructing a time series base pattern library by using a plurality of time series base patterns. The iteration operations includes: using the at least one data fragment as at least one update time series fragment; dividing each update time series fragment into a plurality of update data fragments; using each update data fragment that does not satisfy the iteration termination condition as a new update time series fragment; and using each update data fragment that satisfies the iteration termination condition as a time series base pattern.

  • Patent number: 11375906
    Abstract: A method for detecting fetal blood oxygen saturation, including: using at least two detection light of different wavelengths, to irradiate a fetus in an examined pregnant woman's abdomen in a time-sharing manner and acquiring first photoplethysmography signals corresponding to the abdomen under irradiation of the respective wavelengths of detection light, and to irradiate a detection site except the examined pregnant woman's abdomen in a time-sharing manner and acquiring second photoplethysmography signals corresponding to the detection site under irradiation of the respective wavelengths of the detection light; determining a target photoplethysmography signal of the fetus that corresponds to the detection light of each wavelength, according to the first photoplethysmography signals and the second photoplethysmography signals that correspond to the detection light of each wavelength; and determining the fetal blood oxygen saturation, according to respective target photoplethysmography signals determined.

  • Publication number: 20210244337
    Abstract: An electrocardiograph acquisition circuit, device, method and system are provided. The electrocardiograph acquisition circuit includes: a wireless transmission circuit configured to receive a first electrocardiographic voltage from a second electrocardiograph acquisition device; an electrocardiograph electrode configured to detect an electrical signal on biological skin; an acquisition circuit configured to obtain a second electrocardiographic voltage by acquiring the electrical signal detected by the electrocardiograph electrode; and a control circuit configured to obtain an electrocardiograph index signal by processing the first electrocardiographic voltage received by the wireless transmission circuit and the second electrocardiographic voltage acquired by the acquisition circuit based on a first acquisition time of the first electrocardiographic voltage and a second acquisition time of the second electrocardiographic voltage.

  • Publication number: 20210008334
    Abstract: An eyeshade and an electroencephalogram detection system are provided. The eyeshade includes an eyeshade main body; and an electroencephalogram acquisition unit, a controller and a heating unit which are disposed on the eyeshade main body. The electroencephalogram acquisition unit is configured to acquire a brain electrical signal of a wearer. The controller includes a converter and is configured to receive the brain electrical signal from the electroencephalogram acquisition unit, the converter is detachably coupled to the electroencephalogram acquisition unit and is configured to convert the brain electrical signal into a communication signal and transmit the communication signal to outside when coupled to the electroencephalogram acquisition unit. The heating unit is configured to heat an eye region of the wearer.
