  • Patent number: 10278647
    Abstract: A method and corresponding apparatus employ a time-varying spectral analysis approach for reconstructing a heart-related signal that includes motion artifacts. The motion artifacts are produced by motion of a biomedical sensor relative to a sensing location. By comparing time-varying spectra of the heart-related signal and a motion signal, those frequency peaks resulting from the motion artifacts may be suppressed in a time-varying spectrum of the heart-related signal. The time-varying spectral analysis based approach enables the heart-related signal to be reconstructed with accuracy by suppressing the motion artifacts. Example applications for the method and corresponding apparatus include training aids (e.g., runners' heart-rate monitors) and hospital patient heart-rate monitors.

The controller is located in the second location and communicates wirelessly with the first and second monitoring devices and the transmitter. The transmitter transmits wirelessly live data feeds to the first and second monitoring devices and to the controller and the live data feeds include the sound and image data of the user and the user's vital data.

  • Patent number: 9518828
    Abstract: The invention relates to measuring devices to be used in physical measuring, and more particularly, to a method and a device for measuring the progress of a moving person. In the solution according to the invention the quantities describing the progress of the moving person are being calculated based on step cycle-specific acceleration stage characteristic accelerations a+ and step cycle-specific braking stage characteristic acceleration a? obtained from acceleration values measured by means of an acceleration sensor, and on the measured time. The invention aims at providing a solution, better and simpler than prior solutions, for measuring the progress of a moving person, which solution is applicable for use in a multitude of measuring solutions for ways of locomotion of various types.

  • Patent number: 9442586
    Abstract: A sampling unit acquires a sample data series of a signal indicating a touch state quantity detected in a touch panel. A discrete Fourier transformation unit transforms the sample data series into the frequency domain. The frequency spectral analysis unit determines a frequency spectral distribution in accordance with the sample data transformed into the frequency domain. A peak detection unit detects a peak in a frequency band of a pulse in the frequency spectral distribution and finds the frequency of the detected peak so as to determine the pulse.

  • Patent number: 9370691
    Abstract: A method of determining a user's training load, includes determining protein combustion information and determining the user's training load based on the protein combustion information. The protein combustion information may be determined using heart rate information, activity information, carbohydrate reserve information determined using a carbohydrate combustion model and carbohydrate reserve information representing the user's carbohydrate reserves at a beginning of at least one exercise session, fitness information, intensity information, nutritional intake information representing nutritional intake during at least one exercise session, and/or a fat combustion model. The user's training load may be determined based on a mechanical stimulus and/or a modality. Recovery time information may be determined based on the training load. A corresponding apparatus and computer-readable medium correspond to the above method.

  • Patent number: 9307943
    Abstract: A method for determining an appropriateness of a calculated pulse rate is provided. In a pulse rate monitor, a pulse rate calculation part calculates the pulse rate of the test subject based on the result detected by a pulse wave sensor. Then, a pulse rate difference calculation part calculates a difference (pulse rate difference) between a reference pulse rate and a calculated pulse rate, and a deviation degree is determined based on the pulse rate difference. Also, a SN ratio calculation part calculates a SN ratio of a pulse wave signal detected by the pulse wave sensor, and a reliability of the calculation result in the pulse rate calculation part is determined based on the SN ratio. Then, a pulse rate appropriateness judgment part determines an appropriateness of the calculated pulse rate based on the pulse rate difference (deviation degree) and the SN ratio (reliability).
