An energy measuring device made of two same size blocks. The outline of two metal ball bearings are traced onto the blocks which are then drilled out where the tracings are marked. Ball bearings are inserted into the resulting holes. With the bearings fitted in place a dowel is inserted through the centers of the bearings to check out the fitting. The dowel is then removed and replaced with a roller. Next, a generator and gear assembly is fabricated comprising two gears and a band, the selected gears having a 10:1 ratio. A string is now loosely attached to the dowel so it can be wound up and released to measure an amount of energy created. The string is marked from 12-24 inches, in 6 inch increments, and these markings are used to control speed and turns for tests related to harnessing otherwise wasted energy.

A diagnosis system diagnoses the integrity of an opening/closing device capable of opening and closing by driving a motor. A driving current acquisition unit acquires a driving current of the motor. A diagnosis unit defines a current waveform from a temporal change of the driving current acquired by the driving current acquisition unit and diagnoses the integrity of the opening/closing device based on the current waveform.
