  • 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.
