发明名称 Portable radio telephone with impulse movement or sound off-hook production and signalling
摘要 A portable radio telephone operating under the control of a microprocessor includes a disturbance sensitive switch sensitive to shock, movement or other physical disturbance or to a voice which causes the telephone to go "off-hook" if the telephone is disturbed during an incoming call. The user can thus answer an incoming call very quickly before the system times-out the call by gently striking or simply moving the telephone or talking or shouting to it even when the telephone is in a relatively inaccessible location. In a preferred embodiment the user is required to confirm the off-hook condition by pressing one of the keys on the telephone keypad. The telephone may continue ringing until the confirmatory keystroke has been effected.
