Circuit for exclusion zone compliance

Image Number 3 for United States Patent #7898409.

A circuit for exclusion zone compliance is recited. In one embodiment, the circuit comprises a satellite navigation signal reception component configured for receiving at least one signal from at least one Global Navigation Satellite System satellite and a navigation data deriving component configured for deriving position data and a clock time from the at least one signal. The circuit further comprises a non-volatile memory component configured for storing an encrypted data set describing the boundaries of an exclusion zone and a data blocking component configured for controlling the accessing of the encrypted data set. The circuit further comprises a data control component configured for blocking the output of a signal from the circuit in response an indication selected from the group consisting of: an indication that the circuit is located within an exclusion zone and an indication that output of said signal is not permitted based upon said clock time.
