Cell phone muting override system
First Claim
1. A system for restricting radio frequency transmissions of a cellular telephone within a restricted area comprising:
- i) a restricted area wherein all radio transmissions are restricted;
ii) a plurality of cellular telephones disposed within the restricted area, each cellular telephone including a radio frequency transmitter and a radio frequency receiver for receiving radio-frequency signals;
iii) a radio frequency transmissions inhibitor, the radio frequency transmissions inhibitor capable of selectively disabling the radio frequency transmissions of a first selected subset of the plurality of cellular telephones; and
iv) an emergency override, the emergency override capable of selectively enabling the radio frequency transmissions of a second selected subset of the plurality of cellular telephones, wherein if a cellular telephone is a member of the first selected subset and a member of the second selected subset, the cellular telephone'"'"'s radio frequency transmissions are enabled.

Abstract
The disclosed invention relates to a system for restricting radio frequency transmissions within a restricted area and more particularly to a mechanism for overriding the restriction of radio frequency transmissions within a restricted area using an override mechanism. A restricted area is defined wherein all radio frequency transmissions are restricted. Within the restricted a plurality of cellular telephones is disposed, each with a radio frequency transmitter and a radio frequency receiver. An emergency override is also disposed within the restricted area, the emergency override capable of selectively enabling communications of a selected subset of the cellular telephones disposed within the restricted area.

10. A system for restricting the ringing of a cellular telephone within a restricted area comprising:
-
i) a restricted area wherein ringing of all cellular telephones disposed within the restricted area is muted;
ii) a plurality of cellular telephones disposed within the restricted area, each cellular telephone including a radio frequency receiver for receiving radio-frequency signals and a ringer;
iii) a ring inhibitor, the ring inhibitor capable of selectively disabling a first selected subset of the plurality of cellular telephones; and
iv) an emergency override, the emergency override capable of selectively enabling ringing of a second selected subset of the plurality of cellular telephones, wherein if a cellular telephone is a member of the first selected subset and a member of the second selected subset, the cellular telephone'"'"'s ringing is enabled. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
