An approach is proposed for detecting heart rate for controlling electrically assisted bicycle. This method is based on capacitive coupling involving the electrode, the cloth and the skin. A proposed system was fabricated to explore the feasibility of the approach and evolution experiments were conducted for 4 men. Validation of the system revealed the following: (1) ECG signal was successfully obtained...
An improvement technique of position-sensing characteristics in self-sensing active magnetic bearings is proposed. Winding-current interference to the estimated position signal is reduced by a modified signal path. The gain and phase characteristics of the proposed self-sensing method agree well with a reference sensor signal up to over 1 kHz
A zero-bias-current self-sensing active magnetic bearing is proposed. One degree-of-freedom (DOF) of the rotor is controlled by a pair of electromagnets, which are alternatively energized by the proposed circuit. The rotor position of the one DOF is measured by using both electromagnets: the non-energized electromagnet also contributes to the position sensing. The proposed method gives good linearity...
This paper proposes and discusses single-phase rectifiers with a triple-frequency pulsewidth modulation (PWM) scheme. The rectifiers consist of high-, medium-, and low-power sub-converters operated at low, medium, and high frequencies, respectively. The proposed rectifier can equivalently operate as one rectifier that delivers the highest power at the highest frequency defined in the triple-frequency...
Recent theoretical developments now allow for reliable calculation oftunneling matrix elements in unimolecular biological electron transferreactions that have been tested experimentally. Most biological ETprocesses, however, are bimolecular, or involve large-scale proteindomain motions. In this paper, initial advances in this direction bystudying the inter-protein electron transfer between cytochrome...
