Safe, constant-current, electric-shock stimulator

Medical & Biological Engineering, 1973
A constant-current, 1 kHz electrical-shock stimulator is described. It can be battery-powered or run from a well isolated power supply (also described). The device can supply up to 25 mA to loads from zero to 16 kω, with reduced output at higher resistive loads. A tenfold change in load produces less than a 1 mA change in output current.

Current and Constant Prices

2017
Harmonized Indices of Consumer prices (HICP) are constructed in each member state of the European Union for the purpose of international comparisons of consumer price inflation. HICP’s are published by Eurostat – The European Commission’s statistical arm – and have been published monthly since March 1997.

A Constant-current AC shock generator

Conditional Reflex, 1970
A device has been developed for the effective delivery of a preset constant current AC electric shock. The shock intensity is adjustable from zero to a maximum of 10 ma as the voltage varies between 0 to 5 kv. The 5-kv, 60-HZ, AC voltage insures a constant-current output regardless of skin contact resistance changes.

A CONSTANT CURRENT SKIN RESISTANCE COUPLER

Psychophysiology, 1969
ABSTRACTA constant current skin resistance measuring device with separate outputs, linear in ohms, for skin resistance responses (SRR) and skin resistance level (SRL) is described. The unit is made as a coupler for an Offner Type R Dyno‐graph, and has built‐in calibration facilities.

Constant Current Generators (CCG)

2008
The various kinds (8) of CCG (constant current generators, sources and sinks) are presented in this chapter. It includes all relevant equations that allow calculating operating points, output impedances, and all noise aspects of the various generators.
