Abstract
Systems and methods for a redundant wireless safety system that provides a second level of safety protocol when a worker is exposed to a more dangerous work environment. In an embodiment, such a machine may be configured to perform a specific manufacturing function wherein the machine may include first and second transceivers for maintaining enabling signals for functionality of the machine. The system may further include a base station (e.g., remote control) configured to operate in conjunction with the machine that in turn includes third and fourth transceivers also configured to maintain enabling signals for machine functionality. Machine functionality may be interrupted by an interrupt switch disposed in the machine. That is, the interrupt switch may be configured to enable functionality of the machine if and only if the first transceiver maintains periodic communication with the third transceiver and if the second transceiver maintains periodic communication with the fourth transceiver.
