Anthropometric measuring equipment - equipment used mainly in hospitals to measure the height and other dimensions of human beings.
Current range of equipment covers a number of instruments, all mechanical and based on a 'head' which moves driving a gear train which in turn drives a mechanical readout counter using the same principle as the wheeled instruments used by surveyors to measure road distances.
Objective is to develop an electronic (or possibly a microelectronic) version of the instruments. The overall specification is as follows:
Mechanical gear train to be replaced.
One standard measuring head for the complete range of measuring equipment with a range of 0-2000mm in increments of ±1mm with an accuracy and repeatability of ±1.5mm.
Battery operated.
Operation to be as simple as the current units, with no requirement for zero adjustment, etc.
Anyone who has the diagram of the electronic system, or who could design a simple system, please help me. I have searched numerous websites, but none is providing the details.
Thank you.
