ABSTRACT:
An alarm system formed by a wrapper includes an energy source, an operator grip-pressure-controlled switch, an orientation responsive switch, and an audio resonator. The wrapper is secured to an operator controllable member, such as a steering wheel, by being folded over the member upon itself and secured using, for example, a fabric fastener interlock. In operation, the user places his hand upon the pressure control switch included within the wrapper. When the grip of the user becomes relaxed, for example, due to inattention or fatigue, the switch operates the resonator and an alarm is sounded. The orientation responsive switch controls disablement and enablement of the alarm system in response to displacement of the operator controllable member.
