Abstract: The present invention provides an electric bike with capability of self-charging. The electric bike is fixedly supported by supporting legs so as to be operated in a stationary point. A user steps on a petal assembly of the electric bike to drive a wheel to rotate. The electric bike further includes a power-generating device, a controller, a battery and a damper. The controller is used to receive a power source outputted by the power-generating device and convert the power source into a plurality of DC power sources to charge the battery. The damper consumes a portion of electricity generated by the power-generating device. With the above arrangement, the electric bike can be charged by itself while the user is exercising.

Abstract: An exercise apparatus includes an exercise machine and a media device. The exercise machine includes an exercise device and a controller. The exercise device generates an electrical output through an exercise mechanism that drives operation of a power generating unit. The controller includes a status data generating unit for receiving the electrical output and generating exercise status data based on the electrical output, a control unit storing user-configured data and the exercise status data, and a resistance controlling unit controlled by the control unit for causing the exercise status data to conform with the user-configured data. The control unit and the media device are configured to operate according to a personal computer compatible protocol. The user-configured data is established and configured through the media device. The exercise status data is stored in or displayed by the media device.

Abstract: A motor control device for controlling rotation of a brushless DC motor of a ceiling fan includes a receiver unit that receives an input signal and outputs a command signal, a magnetic sensor unit for detecting a magnetic pole variation of the brushless DC motor so as to generate a position signal, a processing unit that is electrically connected to the receiver unit and the magnetic sensor unit and that generates a control signal, a motor drive unit that is electrically connected to the processing unit and the brushless DC motor and that generates a drive signal for driving the brushless DC motor, an AC to DC converter unit that rectifies and filters a grid power to generate a first DC power for the motor drive unit, and a DC to DC converter unit that is electrically connected to the aforementioned units and that generates a second DC power.
