1. A method for synchronizing data, comprising:
- providing a plurality of remote sensors, each remote sensor including a transducer, a transmitter, a receiver, and a remote sensor clock having an operating speed;
providing a central processor, the central processor including a processor, a transmitter, a receiver, and a central processor clock having an operating speed;
transmitting a signal from the central processor to each of the plurality of remote sensors to initiate a common measurement period at each of the plurality of remote sensors based on the transmitted signal from the central processor, each of the plurality of remote sensors performing a measurement event during the common measurement period;
receiving a remote sensor signal from each of the plurality of remote sensors at the central processor, the remote sensor signal including a first portion indicative of the operating speed of the remote sensor clock and a second portion indicative of the elapsed time since any measurement event during the measurement period;
normalizing the remote sensor signals received at the central processor from each of the plurality of remote sensors based on the operating speed of the central processor clock; and
determining with the central processor the relative time of each measurement event for the plurality of remote sensors based on the second portion of the remote sensor signals received from the plurality of remote sensors indicative of the elapsed time since any measurement event during the measurement period.

Abstract
Disclosed is an apparatus and methodology for synchronizing data received at a central location that has been collected at plural remote locations and separately transmitted to the central location. A plurality of remote sensors is provided and configured to be simultaneously triggered to begin a data collection sequence and to subsequently transmit the collected data along with remote sensor identification data and timing information to the central location. Timing information may include a specifically transmitted time reference or may be derived based on successive transmissions from the individual remote sensors.
