Abstract: A wireless deadman system for controlling operation of equipment from a portable device includes a base station with an equipment control system, the base station wirelessly transmitting operational parameters for the equipment. A portable display unit has a housing, an electronic display, an electronic circuit, and a data receiver. A portable authorization device includes a liveness sensor and transmits an authorization signal when the sensor detects a liveness input. The display unit receives an authorization status for operation of the equipment from the portable authorization device and receives the operational parameters from the base station, the display displaying the authorization status and the operational parameters of the equipment on the electronic display. The equipment control system allows the equipment to operate when the authorization signal is provided and prevents the equipment from operating after the authorization signal is no longer provided.
