发明名称 System for selective prevention of non-emergency use of an electronic device
摘要 A system for selectively disabling use of at least selected features of a stand-alone electronic device under a predetermined set of conditions. The system establishes a state of the set of conditions as being satisfied or unsatisfied, communicates the state to the electronic device, and disables the selected features if the state is satisfied. In one embodiment, the system may advantageously be used to prevent vehicular accidents by at least partially disabling non-emergency use of a wireless telephone in a moving vehicle. In another embodiment, the system may be used to disable features of an electronic device within a predetermined area having a boundary that is independent of a communications network cell.
