Wireless position-time synchronization for scanning sensor devices
First Claim
1. A method comprising:
- wirelessly transmitting one or more messages to first and second sensor assemblies in order to synchronize clocks of the sensor assemblies;
wirelessly receiving multiple sensor measurements of at least one characteristic of a web of material from the sensor assemblies, the sensor measurements captured as the sensor assemblies move across the web of material along opposite sides of the web;
receiving timestamps and position data associated with the sensor measurements; and
correlating the sensor measurements, timestamps, and position data to identify sensor measurements from the first and second sensor assemblies associated with a same position of the web and a same time.

Abstract
A method includes wirelessly transmitting one or more messages to a sensor assembly in order to synchronize a clock of the sensor assembly. The method also includes wirelessly receiving multiple sensor measurements of a characteristic of a web of material from the sensor assembly. The method further includes receiving timestamps and position data associated with the sensor measurements. In addition, the method includes correlating the sensor measurements, timestamps, and position data. The sensor measurements from the sensor assembly could be timestamped, and the position data could include timestamped position data. The timestamped position data could be received from a source other than the sensor assembly. The method can further include generating a cross direction profile of the web of material using the sensor measurements, timestamps, and positions.
