Patent ID: 7411869

Claim:
A wireless synchronous time keeping system comprising: a primary device including a first receiving unit to receive a first signal, the first signal including a time component, a first processor coupled to the first receiving unit and operable to process the first signal and produce a processed time component; a first internal clock to store the processed time component and to increment the component thereafter to produce a first internal time, a transmitting unit to transmit a second signal, the second signal including the first internal time and an event, the event including an instruction and a time element; and a secondary device including a second receiving unit to receive the second signal, a second internal clock to store the first internal time and to increment the first internal time thereafter to produce a second internal time, an event switch operable to execute the instruction when the second internal time matches the time element, and a sensor coupled to the event switch and operable to provide feedback regarding the instruction.
