Abstract
Several remote control and signaling systems 10, 80 allow for the remote operational control of an apparatus 20, by a transmitter 14. These systems 10, 80 obviate the need for a line of sight relationship between transmitter 14 and control apparatus 20 and are further adapted to receive original control signal 15 and to thereafter generate a relatively high frequency signal 22, to facilitate this desired control. Moreover, a transmitter mounting assembly 90 is adapted to removably mount several dissimilar transmitters 98, 100, 102 and which allows for the remote control of a plurality of apparatuses 20 in an efficient manner.
