Title: Heartbeat stimulator for emergency - varies frequency temporarily, having HV circuit supplying high impedance loading network via non-metallic path
IPC: A61N1/362
Filed: 1980-07-16
Abstract: The heart beat stimulator can be used on a patient in an emergency situation or for a diagnostic purpose. It can be inserted to vary the heartbeat temporarily. The catheters used are of a relatively simple design. The current is transmitted through a non-metallic medium with a relatively low electrical conductivity. The heartbeat simulator consists of a high voltage circuit supplying loading circuit with a high impedance. The current is thereby reduced to the level needed to produce the heart simulation. The current path consists of an electrolytic solution or a thin layer of a non-metallic material.

Patent PT-74350-A (PT)
IPC: H02P7/29
Filed: 1982-01-28
Abstract: The power supply to an electric actuating motor is regulated by reducing the differences between current intensity or voltage and a reference value. Two transducers measure the current intensity and the voltage. A selection stage chooses the higher of the two values and a comparison stage delivers a difference signal with respect to the reference value established by a stage of the potentiometer type. A regulator produces an action which is compared within a comparator with a sawtooth signal emitted by an oscillator. Depending on the sign of the comparison, a control stage supplies the motor during a variable fraction of the period of the oscillations.
