    Abstract: An AC adapter including an AC-side plug module and a DC-side connector module coupled to each other is provided. A first voltage-reducing element and a relay are electrically coupled to an AC power supply. An AC-to-DC converter is electrically coupled to the relay. The DC-side connector module has a mechanical switch element electrically coupled to the relay and the first voltage-reducing element. When the DC-side connector module is connected to a device socket, the mechanical switch element is turned on and the relay is enabled, so that the electrical power of the AC power supply is transmitted to the AC-to-DC converter through the enabled relay. When the DC-side connector module is disconnected from the device socket, the mechanical switch element is turned off and the relay is disabled, so that the electrical power of the AC power supply is not transmitted to the AC-to-DC converter.

    Abstract: An asynchronous converter comprises a torque motor and a rotating electric machine having two sets of windings, each of the windings connected to a respective polyphase electric circuit. The two windings have the same number of magnetic poles and generate coincident rotating magnetic fields having the same direction of rotation. When a torque is applied (e.g., to the shaft of a rotor carrying one of the windings) in the same direction as that of the rotating magnetic fields, electric power is transferred from the rotor-connected circuit to the stator-connected circuit. When the direction of the torque is reversed, the direction of the power transfer is also reversed. The two polyphase circuits may differ in voltage, in frequency and in number of electrical phases, but it is expected that in most cases the number of phases will be equal to three for both circuits and the operating frequencies of the two circuits will differ by no more than a few percent.

    Abstract: A portable electric impulse generator is provided having an impulse triggering reed switch that is actuated by a rotatable magnet which, in turn, is driven at various preselected rates of speed by a differential gear train. The differential gear train is driven at a rate determined by the selective energization of a plurality of synchronous motors that are operatively coupled to input gears of the gear train.
