  • Patent number: 9931081
    Abstract: The invention proposes an apparatus for reducing motion artifact in an ECG signal of a patient. The apparatus comprises a calculating unit configured to calculate a mean value beat from the ECG signal; a first obtaining unit configured to obtain a residual signal based on the ECG signal and the mean value beat calculated from the ECG signal; a filtering unit configured to perform filtering of the residual signal with one or more cut off frequencies; a second obtaining unit configured to obtain a modified ECG signal based on the filtered residual signal and the mean value beat; and a determining unit configured to determine the one or more cut off frequencies of the filtering based on an acceleration signal representative of motion status of the patient. By using the proposed apparatus, motion artifacts can be greatly removed from the ECG signal and the quality of the ECG signal can be therefore improved.

  • Patent number: 9905983
    Abstract: A brush for an electric motor has a brush body having a front end surface configured to make sliding electrical contact with a commutator of the motor. First and second side surfaces are connected to the front end surface. The first side surface and the second side surface are positioned on opposite sides of the brush body in a rotational direction of the commutator. The front end surface has a first contact surface and a second contact surface that contact the commutator earlier than other regions of the front end surface, and are respectively positioned on diametrically opposed corners of the front end surface. In an initial state, the width of the contact area between the brush and the commutator is increased to extend the commutation time.

  • Patent number: 9826937
    Abstract: The present invention provides a method and apparatus for reducing motion artifacts in ECG signals. According to an aspect of the present invention, there is proposed a method of reducing motion artifacts in ECG signals, comprising: acquiring a current beat from a continuously measured ECG signal of a patient; calculating a correlation coefficient between a previous mean value beat and the current beat in the ECG signal; determining the weights to be assigned to the previous mean value beat and the current beat based on the correlation coefficient; and calculating a current mean value beat based on the previous mean value beat, the current beat, and the weights thereof. Accordingly, the novel method of deriving the current mean value beat may reduce ECG artifacts due to patient movement in such a manner that the SNR of the ECG signal can be improved substantially.
