`
`ABSTRACT
`
`System and method for measurement, DAQ, and control
`operations which uses small form-factor measurement mod(cid:173)
`ules or cartridges with a re-configurable carrier unit, sensors,
`and a computer system to provide modular, efficient, cost(cid:173)
`effective measurement solutions. The measurement module
`includes measurement circuitry, e.g., signal conditioner and/
`or signal conversion circuitry, and interface circuitry for com(cid:173)
`municating with the carrier unit. The module communicates
`interface information to the carrier unit, which informs the
`computer system how to program or configure a functional
`unit on the carrier unit to implement the communicated inter(cid:173)
`face, or sends the information directly to the computer sys(cid:173)
`tem. The computer system programs the carrier unit with the
`interface, and the programmed carrier unit and measurement
`module together function as a DAQ, measurement, and/or
`control device. The carrier unit may receive multiple car(cid:173)
`tridges, each having a respective interface protocol, where the
`carrier unit is configurable to support the respective protocols
`sequentially and/or in parallel.
