ABSTRACT:
This invention relates to a system for disabling a cellphone in the presence of certain conditions, and for switching it off in the presence of some other conditions, while allowing its use in the normal fashion in the absence of these two sets of conditions. Thus, this system regulates cellphone use in accordance with specified restrictions in specific locations, and allows its normal functioning when these restrictions are not required. Specifically, a first condition is an attempt to operate a cellphone by the driver of a vehicle having its ignition on and/or moving above a certain speed. In such a condition the system would automatically disable the OK switch of a cellphone and may also perform the CALL END function. In the second condition the system automatically switches off any cellphone in the ON condition being carried on the person of an individual occupying a seat in an aircraft, or a committee room, or any other such location where such a restriction is envisaged. The system also makes a provision for automatic sequential dialing of a specified set of numbers like the police, medical services etc. during an emergency by allowing overriding any regulatory restriction. In addition, this invention also relates to control circuits provided in said system for preventing tampering with or bypassing the system by cellphone users.
