Vigilance Control
The main safety failing with the basic dead man’s system is the possibility of the operating device being held permanently in position, either deliberately or accidentally. Vigilance control was developed to detect this condition by requiring that the dead man’s device be released momentarily and re-applied at timed intervals.
There has also been a proposal to introduce a similar system to automotive cruise controls.
A hybrid between a dead man's switch and a vigilance control device is a dead-man's vigilance device.

Famous quotes containing the words vigilance and/or control:
“The General Order is always to manoeuver in a body and on the attack; to maintain strict but not pettifogging discipline; to keep the troops constantly at the ready; to employ the utmost vigilance on sentry go; to use the bayonet on every possible occasion; and to follow up the enemy remorselessly until he is utterly destroyed.”
—Lazare Carnot (1753–1823)
“All industries are brought under the control of such people [film producers] by Capitalism. If the capitalists let themselves be seduced from their pursuit of profits to the enchantments of art, they would be bankrupt before they knew where they were. You cannot combine the pursuit of money with the pursuit of art.”
—George Bernard Shaw (1856–1950)
