ABSTRACT

A measurement system for measuring hand tools includes a number of
instrumented tools and a data collector. The data collector has a processor
which can operate in a task analysis mode in which data is received, stored,
and processed over a user-determined period of time. A number of different
tools with different adaptor configurations can be coupled to a receptacle on
the housing of the data collector. The collector has recognition circuitry for
determining which type of tool is plugged into the receptacle, and, in
response, the processor retrieves parameters needed to process the data and
which are related to the recognized tool. The instrumented tools are designed
to simulate actual tools used in the work place, and thus have substantially
the same size, shape, weight, weight distribution, and feel of actual working
models of the tools. The sensors can include strain gages for measuring force
and torque, position detectors for measuring hand position, sensors for
measuring grip, accelerometers for measuring acceleration of the tools and
sensors for measuring an angle of rotation of a tool.
