摘要： PROBLEM TO BE SOLVED: To furthermore intensity stimulation from a state where voltage is saturated at the time of stimulating an organism by AC power varying voltage corresponding to pattern information. SOLUTION: Pattern information previously registered in a pattern storing means 101 is read with time by an information reading means 102 and AC power varying voltage corresponding to this pattern information read with time is applied to the living body by a prescribed frequency by an organism stimulating means 103. At this time, when pattern information read with time becomes a specific section set in advance, the frequency of AC power to be added to the living body is varied by a stimulation varying means 104 to vary the intensity of stimulation to the organism is varied by the frequency independent from voltage.

摘要： PROBLEM TO BE SOLVED: To make it possible to always supply optimum power to a power receiving device following a change in a load even if the load changes. SOLUTION: When the secondary-side power consumption (load) increases and thereby the supply of power becomes insufficient at the power receiving device 5 side, a voltage status signal generator 54 detects the decrease in supply voltage Vdd and generates a voltage status signal VST which shows that the supply of power is insufficient. A signal transmitting and receiving circuit 55 sends the generated voltage status signal VST by wireless to a power transmitter 3. The voltage status signal VST sent by wireless is received by a signal transmitting and receiving device 41 of the power transmitter 3. A PWM controlling circuit 33 makes such a control as to increase the power to be supplied to the power receiving device 5 based on the voltage status signal VST input through the signal transmitting and receiving device 41.

摘要： PURPOSE: To enable preventing of a positional deviation of a transmitting coil by finding out the optimum position of the transmitting coil easily in an electric stimulator. CONSTITUTION: An electric stimulator is provided with a stimulator 12 buried in vivo and a controller 11 to supply a power to the stimulator arranged extracorporeally. The stimulator is provided with a modulator 15 which obtains the position of receiving the power as voltage level to feed it back to the controller 11 as receiving level information. With the controller 11, for example, the receiving level information is shown on a display device 11c as detection voltage level. Then, a user determines the optimum mounting position of a transmitting coil 11a according to the detection voltage level. The detection voltage level is monitored during an electric stimulation treatment or the like thereby enabling checking of a positional deviation of the transmitting coil easily.

摘要： PROBLEM TO BE SOLVED: To enlarge the transmission range to an increase in the amount of information of a control signal and a little shifting between a transmit coil and a receive coil by interrupting a carrier wave of power transmission only when a control signal is transmitted. SOLUTION: A carrier wave sent from a power coil for power transmission of a transmit part 10 is received by a power receiving power coil 21 of a receiving part 20 and full-wave rectified to be taken as a power supply 25 of the receiving part 21. When a control signal is transmitted and received by signal transmitting and receiving coils 12, 22 provided on power coils 11, 21, a control circuit 13 of the transmitting part 10 stops transmission of power. The power during the stop of power transmission is covered by the condensed power of a capacitor 24 of a full-wave rectifier 23 which has received power becaused the stop period is comparatively short. Accordingly, it is not necessary to use a coil shaped like a figure of eight, and a circular coil can be used so that the transmit and receive enabled range can be enlarged to lateral shifting of both coils 12, 22.

摘要： PROBLEM TO BE SOLVED: To transmit power efficiently by letting a power carrier frequency control circuit change the power carrier frequency and by controlling it so that the output voltage inside the body can be maximized, when a power transmitting circuit for transmitting the power carrier is provided outside the body and it is linked to a power receiving circuit. SOLUTION: In a power carrier frequency control circuit 8, a CPU 23 stores a received output voltage value into a memory 24 and controls the power carrier frequency in such a way as to increase it, for example, a bit higher than the current frequency. When the output voltage value becomes equal to the voltage value stored in the memory, the control is ended. Conversely, when the output voltage value based on the received voltage is lower than the previously stored voltage value, the power carrier frequency is a bit lowered below the current frequency to perform the control of comparing the received output voltage value with the stored one. This way, the power carrier frequency is controlled so that the received voltage of the power receiving circuit 1 can always be maximized.

摘要： PROBLEM TO BE SOLVED: To make a negative voltage generator needless by applying negative voltage pulse of an indifferent electrode as a common electrode for different electrodes, make switches per channels single and reduce numbers of parts and patterns in the circuit board and to result into small size and light weight. SOLUTION: This apparatus comprises plural channels of different electrodes 1, 2, to be attached to stimulating positions, an indifferent electrode as a common electrode for the different electrodes 1, 2, a D/A converter 12 for generating a positive voltage pulse, and a CPU 11. The output of the D/A converter 12 is connected to the indifferent electrodes, and the electric connections by switches a1, a2, between the different electrodes 1, 2, and GND (ground) are controlled by the CPU 11. A negative voltage pulse corresponding to a positive voltage pulse generated at the indifferent electrodes is applied to load 1, 2, as stimulating positions connected to each of different electrodes, thereby a negative voltage generator is made needless and the single switch per the channel becomes enough, and numbers of parts and patterns in the circuit board can be reduced, thereby small sizing and light weighing can be attained.

摘要： PROBLEM TO BE SOLVED: To quickly deal with variations in the algorithm elements of stimulus outputs by thoroughly understanding the contents of a program including an algorithm of the stimulus outputs. SOLUTION: An algorithm of stimulus outputs is isolated from programs for operating an electric stimulating device, is parameterized, and combined with stimulus pattern data to form a set, which is separated into the parts that require adjustments for individuals and the parts that do not (step 1). The programs for operating the electric stimulating device do not require selection according to individuals. They are inputted via a communications line to a computer in the electric stimulating device, from which they are written into memory (step 12). Pattern data and algorithm elements are isolated from the programs and parameterized, so variations and adjustments can be made to correspond to individual patients without changing the programs.
