This device, already prototyped and demonstrated to work, will provide a simple hand held transducer (actually a commercially available inexpensive edge reading D'Arsonval meter) that plugs into a small timer, integrating amplifier and result display (actually a similar D'Arsonval meter or, if preferred, a digital output display in LCD or LED).
In operation the hand held transducer meter acts as a one axis rotational self—generating accelerometer. Its output voltage, full wave rectified and amplified, is converted to an equivalent current which charges a condenser, the voltage of which is read. Upon reset and restart, the condenser is discharged and a timer started. At the end of a run, the charging ceases, the signal light indicating the end of run is lighted and the reading held.
As used now, there is only one sensitivity scale, but choice of high, low and intermediate scalar would be easy to serve the sick—solid individual trying to become better, the average healthy person who occasionally has reason to become a little shaky and wants to know how badly, or the actual tremor patient who expects to shake but sometimes is worse or better.
The unit can easily be, and probably should be, converted to battery power in order to be completely independent of power supply or line power.
