System and method for accident prevention
First Claim
1. A system for preventing accidents in the operation of a monitored machine or apparatus having first and second hand grips adapted to be grasped by respective hands of a user, the system comprising:
- a user end device or terminal in the first hand grip in direct contact with the respective hand of the user with output means for continuously or periodically transmitting an authorizing user data signal through the body of the user, anda signal receiver assigned to the monitored apparatus or machine and havinginterface means in the second hand grip in contact with the respective hand of the user for receiving the authorizing data signal transmitted through the body of the user from the first grip,means for continuously or periodically testing the received data signal,means for outputting a clearance signal that allows operation of the monitored machine or apparatus after a successful test of the received authorizing user data signal, andmeans for terminating output of the clearance signal following a successful test of the authorizing user data signal when a subsequent test of the data signal fails, whereby the monitored machine or apparatus can only be operated when held by the user with both hand grips.

Abstract
A system for preventing accidents in the operation of a monitored apparatus carried by a user has terminal in direct contact with the body of the user and provided with a circuit for continuously or periodically transmitting an authorizing user data signal through the body of the user. A signal receiver assigned on the monitored apparatus or machine has an interface in contact with the user for receiving the signal, a circuit for continuously or periodically testing the received data signal, another circuit for outputting a clearance signal that allows operation of the monitored machine or apparatus after a successful test of the received authorizing user data signal, and yet another circuit for terminating output of the clearance signal following a successful test of the authorizing user data signal when a subsequent test of the data signal fails.
