Abstract: An electric power supply system cooperated by a battery and a super capacitor includes a power source module and a processing unit. The power source module includes an electric power transformer, a battery, and a super capacitor. The electric power transformer is electrically connected to the battery and the super capacitor. The processing unit is electrically connected to the electric power transformer for controlling the battery to charge the super capacitor, such that both the battery and the super capacitor supply electricity to the load, and such that electricity generated by the load can recharge the super capacitor. The electricity power supply system can avoid an increase of the working temperature of the battery.

Abstract: A deep magnetic field generating apparatus includes a first coil unit and a second coil unit. The second coil unit is connected with the first coil unit, and disposed around the first coil unit horizontally. Accordingly, the deep magnetic field generating apparatus can generate a desired deep magnetic field.

Abstract: An electromagnetic thermotherapy needle includes a needle body, a covering element, and a holding portion. The material of the needle body includes a magnetically susceptible material. The needle body is formed integrally as one piece and includes a front portion and a rear portion. The front portion has a tip end, and a radial width of the front portion is larger than that of the rear portion. The covering element covers the rear portion, and includes a magnetically non-susceptible material. The holding portion is connected with the covering element or the needle body.

Abstract: A method and a system for detecting stand-alone operation of a distributed generating system having a generating source connected in shunt with an independent power distribution system via a first branch breaker are proposed. A voltage or a frequency signal on the independent power distribution system is read. The wavelet transformation is performed on the voltage or frequency signal to form a time versus high-frequency component window and a time versus low-frequency component window for conveniently detecting the perturbation in the time domain of the signal. Next, whether the absolute value of the high-frequency component is greater than a threshold value and whether the duration is longer than another threshold value are determined. If both answers are yes, a stand-alone operation occurs. An alarm signal is immediately generated and sent to the first branch breaker to release the connection between the generating source and the power distribution system.
