Portable radio telephone with impulse movement or sound off-hook production and signalling
First Claim
1. A portable telephone comprising:
- means for sensing physical disturbance of the telephone, the means for sensing disturbance including an orientation insensitive acceleration switch activated by impulsive accelerative movement of the telephone; and
means, responsive to said disturbance sensing means, for producing an off-hook condition in the portable telephone upon a predetermined impulsive accelerative movement of the telephone.

Abstract
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.

19. A method of producing an off-hook condition in a portable telephone comprising steps of:
-
providing the portable telephone with means for sensing physical disturbance of the telephone including an orientation insensitive switch sensitive to impulse accelerative movement and, means responsive to said switch for producing an off-hook condition in the portable telephone; and moving the portable telephone with a predetermined impulsive accelerative movement to produce the off-hook condition.
