Measuring Motion

摘要

A wide range of conventional and MEMS-based accelerometers exists including special-purpose devices that emphasize factors such as ruggedness, small size, accuracy, stability, and cost. Because accelerometers address so many different applications, development of new technologies and enhance- ments to existing ones continue apace. As an example of an enhancement, consider the addition of local nonvolatile calibration storage. Generically, this is termed a transducer electronic data sheet or TEDS and described by the IEEE Smart Transducer Interface standard. A few details were given by PCB Piez-otronics' Mr. Aszkler. "This standard defines the hardware and communications protocol for interfacing a sensor onto a network as well as the architecture and protocol for compiling and addressing nonvolatile memory embedded within an analog sensor.
