Patent ID: 6873573

Claim:
A synchronous event system comprising: a primary event device including a first receiver operable to receive a GPS time signal, a first processor coupled to the first receiver and operable to process the GPS time signal to produce a processed time component, a memory coupled to the first processor and operable to store a programmed instruction including a time element, an internal clock coupled to the first processor to store the processed time component and to increment relative to the processed time component thereafter to produce a first internal time, and a transmitter coupled to the first processor and operable to transmit the first internal time and the programmed instruction; and a secondary event device including a second receiver operable to wirelessly receive the first internal time and the programmed instruction, a second processor coupled to the second receiver and operable to selectively register the programmed instruction, an internal clock coupled to the second receiver to store the first internal time and to increment relative to the first internal time thereafter to produce a second internal time, and an event switch operable to execute the registered programmed instruction when the second internal time matches the time element.
