  • Patent number: 9526889
    Abstract: The electromagnetic stimulation device contains at least a positive electrode and at least a negative electrode. An insulating gap having width of a first distance is maintained between the positive and negative electrodes. The positive and negative electrodes are at least at a second distance away from a nerve to be stimulated. A preset voltage is applied to the positive and negative electrodes so that a low-power, low-temperature, high-frequency electromagnetic field covering and stimulating the nerve is produced between the positive and negative electrodes. By the stimulation of the low-power, low-temperature, high-frequency electromagnetic field, the nerve's threshold is increased, the nerve's transmission capability is reduced, and therefore the nerve pain is effectively eased.

  • Patent number: 8571645
    Abstract: A system and method for evaluating cardiovascular performance in real time and characterized by conversion of a surface potential into multi-channels are introduced. The system includes an electrocardiographic signal measuring unit, a reconstruction unit, and a parameter computation and assessment unit. The reconstruction unit reconstructs electrocardiographic signals (ECG signals) recorded by the electrocardiographic signal measuring unit, such that the ECG signals are reconstructed as ones located at different spatial positions but actually not having a channel. The method includes calculating a variation manifested spatially during an interval between a Q wave and a T wave of an ECG signal against time with a parameter computation and assessment algorithm, to evaluate its discreteness degree and thereby diagnose cardiovascular diseases (CVD) and locate lesions thereof.
