Abstract

Improvements in miniaturization have made two- way radios so small that they may be packaged in the form of a wrist watch. Such small packaging makes push- to-transmit methods awkward, if not impossible. Con- tinuous transmission of signals is detrimental to battery Iife and is a shameful waste of spectrum resources; sound activated transmissions are highly prone to unwanted transmissions due to extraneous environmental sounds. It is desirable to develop a method of signal transmis- sion activation which is complementary to the conveniece of wrist worn two-way radios and is conducive to proper operation of the unit.
