摘要： A method and apparatus for modulating a load by means of control command obtained by varying conduction angle of AC voltage is provided. Under normal operation, conduction angle of AC is approximate to 180 degrees. When a state change command of the load is to be executed, the angle of conduction angle is changed by a conduction angle modulation circuit of control end. After a conduction angle detection circuit of the load end detects the conduction angle, a control unit decodes the information of the conduction angle, and controls the load to perform a corresponding operation. The method and apparatus do not need to add an extra control wiring for the load, and may use the conduction angle of an AC power supply to effectively perform multifunctional modulations on the load with existing power lines, and the defect of a low power commonly found in a traditional dimmer is overcome.

摘要： A control apparatus using variations in conduction angle as control command, wherein a conduction angle modulation module of a traditional leading edge cutoff dimmer is arranged in parallel with a resistance module, so as to enlarge the minimum conduction angle of the leading edge dimmer. The modulation range of the conduction angle of the conduction angle modulation module may be set to a smaller range, so that the modulation range of the resistance module will not be uncertain due to different setting values of the variable resistance, whereby the circuit at load end can be identified readily and function mode switching facilitated to achieve the effect of multiplexing control.

摘要： The present invention relates to an electric massage device capable of gradually increasing a massage force during an outward stroke, mainly comprising a massage module and a control module. In the outward stroke, the control module applies a driving current to the electromagnetic driving unit, and the driving current is gradually increased with an elapsed time or a stroke displacement of the output shaft. In a return stroke, the control module deenergizes the driving current or applies a weak reverse current less than one-fifth of the driving current. At the beginning of the outward stroke, the massage force is weak due to the smaller driving current and hence would not cause skin hurt. At the end of the outward stroke, the massage force is strong due to the greater driving current and hence produces a deep muscle massage effect.

摘要： A control apparatus for a DC inverter electric motor comprising a control module and a controlled module is disclosed. The control module includes a phase-cut that continuously cut off a conduction angle of the AC power supply. The controlled module comprises a rectification circuit for rectifying the AC power supply after being cut off, a phase detection circuit for detecting the cut-off conduction angle, and a control unit for controlling the rotational speed or action of the motor according to the conduction angle that is detected by the phase detection circuit. The control apparatus makes use of the size of the conduction angle to act as control command and thus does not has the issue of reduced power factor. No complex or complicated circuits or wires have to be disposed and the functions can be achieved by making use of existing wiring. It is thus easy to install, cost-effective, and easy to maintain.

摘要： A motor direct drive air pump comprises a housing, a first shaft, and a second shaft. The housing is formed with a left space and a right space; one of the spaces is a compression chamber having an air inlet and an air outlet; the other space has a transmission chamber and a driving chamber; stators are disposed in the driving chamber. A first shaft is disposed through a central partition of the housing; a first impeller is embedded at a portion of the first shaft located in the compression chamber, while a first gear is embedded at a portion of the first shaft located in the transmission chamber, and rotors are embedded at a portion of the first shaft located in the compression chamber. A second shaft is disposed through the central partition of the housing; a second impeller is embedded at a portion of the second shaft located in the compression chamber, while a second gear is embedded at a portion of the second shaft located in the transmission chamber, and the second impeller and the second gear are respectively coupled to the first impeller and the first gear. Therefore, a power outputted from a motor directly drives the first and the second impellers and allow the air pump to operate, without any additional coupling.
