First Claim
Patent Images
1. A wireless telephone comprising a housing adapted for stationary usage and a device for preventing operation of the telephone in the event said housing is moved, said preventing device comprising:
- a motion sensor attached to said housing for generating a movement signal indicating movement of said housing; and
,a microprocessor system for preventing operation of the telephone in response to said movement signal, and comprising software for causing said microprocessor system to be reset in response to said movement signal to an operating stage requiring further input, such that the telephone is disabled until said microprocessor system receives said further input.

Abstract
Method and apparatus for deterring fraudulent use of a fixed wireless telephone, comprising sensing motion of the telephone with a motion sensor and preventing operation of the telephone after it has been placed in motion and until entry of a security code to reset operation of the telephone. A central facility may also be automatically notified in the event movement of the telephone is detected.

8. A wireless telephone comprising a housing adapted for stationary usage and a device for inhibiting unauthorized movement of the wireless telephone, said inhibiting device comprising:
-
a motion sensor attached to said housing for generating a motion signal indicative of mobility of said wireless telephone; and
,a microprocessor system for preventing operation of the telephone in response to said motion signal; said microprocessor system comprising software for causing said microprocessor system to be reset in response to said motion signal to an operating stage requiring further input such that the telephone is disabled until said microprocessor system receives said further input, an input component for entering an authorization code indicating authorized operation of said wireless telephone, and a component for restoring operation of the telephone upon receipt of said authorization code. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of preventing operation of a wireless telephone having a housing upon movement of the housing, said housing being adapted for stationary usage, and said method comprising steps of:
-
receiving a signal from a motion sensor attached to the housing of the wireless telephone; comparing said signal with a threshold to determine that the telephone housing has moved; and
,preventing operation of the telephone upon a determination of telephone housing movement; said preventing step being performed by a microprocessor system comprising software for causing said microprocessor system to be reset in response to said determination to an operating stage requiring further input, such that the telephone is disabled until said microprocessor system receives said further input. - View Dependent Claims (16, 17, 18)

19. A method of inhibiting unauthorized movement of a wireless telephone comprising steps of:
-
attaching a motion sensor to a housing of the wireless telephone; electrically connecting the motion sensor with a microprocessor system of the wireless telephone so that a signal from the motion sensor is detected by the microprocessor system; and
,preventing operation of the wireless telephone after said detection of the signal from the motion sensor; said preventing step being performed by a microprocessor system comprising software for causing said microprocessor system to be reset in response to said detection to an operating stage requiring further input, such that the telephone is disabled until said microprocessor system receives said further input. - View Dependent Claims (20, 21, 22)
