摘要:
A drive device and a drive control method for the electric bicycle are disclosed. The drive device of the electric bicycle is equipped with a power supply/storage unit, a compact motor, an inclination sensor, a brake actuation sensor, a pedal-rotating speed sensor and a drive control module. The drive device performs integrated calculations using the inclination information of the inclination sensor, the brake actuation information of the brake actuation sensor and the pedal-rotating speed information of the pedal-rotating speed sensor, so the drive control modules instructs the compact motor and the power supply/storage unit to quickly enter an auxiliary drive mode for rotating wheels of the electric bicycle, or to enter an energy recovery mode for storing electrical energy generated by the compact motor.
摘要:
A compact cassette recorder capable of loading digital or analogue cassettes which comprises: (a) a cassette holder which is dimensioned for insertion of a digital or an analogue compact cassette; (b) a base plate mounted in the cassette holder, the base plate being disposed in a parallel relationship with respect to the digital or analogue cassette when the latter is inserted inside the cassette holder; (c) a guiding slot formed on the base plate; (d) a pin mounted in the base plate and is slidable along the guiding slot, the pin has a projecting height which is slight less than the depth of the recessed region of the digital cassette so as to allow the pin to move into the recessed region and in contact with an edge of the digital cassette cover when the digital cassette is inserted into the cassette holder; and (e) a return spring for retaining the pin in the initial position until the pin is being pushed. The guiding slot is so structured to have an initial, an intermediate and an end position such that (a) the pin, while in the initial position, will be received by the recessed region of the digital cassette when the digital cassette is first inserted into the cassette holder, and the initial position of the guiding slot enables the pin to be in a position to open the cover; (b) when the digital cassette is pushed further inside the cassette holder into a working position, the pin is pushed from the initial position to the intermediate position, this movement causes the cover of the digital cassette to open; (c) when an analogue cassette, which does not have a recessed region, is inserted into the cassette holder and pushed into a working position, the pin will be pushed all the way to the end position thus will not interfere with a working of the analogue cassette.
