First Claim
Patent Images
1. A load indicating device comprising:
- a load indicating member having an identifying element on the load indicating member;
an ultrasonic transducer permanently associated with the load indicating member, for communicating with the load indicating member;
means for making ultrasonic pulse-echo time-of-flight measurements in the load indicating member, for communicating with the ultrasonic transducer;
a reader for accessing the identifying element on the load indicating member; and
an Internet connection coupling the means for making ultrasonic pulse-echo time-of-flight measurements and the reader with a database containing data relating to the load indicating member having the identifying element.

Abstract
A load indicating member is provided with an identifying element which can be accessed and used to determine ultrasonic measurement parameters specific to the load indicating member to provide more precise and more reliable load measurements by compensating for differences resulting from manufacturing variations in individual load indicating members. The parameters specific to the load indicating member can be stored in coding applied to the load indicating member or in a database that can be accessed remotely, for example, using the Internet.
