System for generating electrical pulses for relieving the pain of the patient comprising a pulse generator and a controller for modulating the parameters of the output pulses of the pulse generator to fluctuate in accordance with the 1/f rule; i.e. the spectral density of the fluctuation varies inversely with the frequency.

Method and randomized electrical stimulation system for pain relief

A positioning control system which has a servo system provided with a position feedback system for detected positional information and a velocity feedback system for detected velocity information of a motor and in which the motor is driven by the servo system in accordance with commanded positional information to position a movable machine part of a numerical-controlled machine. The disparity between the detected velocity of the movable machine part and the detected motor velocity is fed back to the control input side of the motor, thereby suppressing vibration of the movable machine part at the moment of completion of the positioning operation.

Positioning control system

System for measuring or monitoring the intracranial pressure which comprises a non-elastic detecting pouch to be inserted into the space between the skull and the cerebrum, a flexible tube connected to the pouch, a device for supplying a liquid into the pouch through the flexible tube and a device for measuring the pressure of the liquid in the pouch. When the pressure of the liquid reaches the intracranial pressure, the curve showing relation between liquid pressure vs. pouch volume flattens. Thus, by measuring the pressure of the flattened region, intracranial pressure may be determined.
