  • Apparatus for remote activation of equipment and demolition charges
    Patent number: 6546873
    Abstract: An apparatus for the activation of a remote device having a transmitter to generate and transmit user-set special coded signals. The transmitter has a function selector switch to select modes of operation for the transmitter. Included is also a receiver to receive the user-set special coded signals, and the receiver also has a function selector switch to select modes of operation for the receiver. The function selector switch selects the following modes of operation for the transmitter: (a) a “transmit/fire” mode that enables a fire signal to be transmitted to the receiver; (b) a “wake-up” mode that enables a set-up receiver mode for immediate firing; (c) a program mode for low power transmission of programmed codes; and (d) a “test” and operational mode that enables an operational test of the apparatus with no firing output.
