Abstract
Restraint apparatus for prisoners is worn beneath ordinary clothing so as to be unseen by the general public, in order that the prisoner's presumption of innocence not be denigrated by public display as is the case with manacles or the like. The apparatus operates by remote activation of an effective but nonlethal impact, such as a brief electrical interference with the somatic nervous system, or discharge of a small dose of tear gas or mace into the prisoner's breathing space.
