Abstract: An electronic monitoring circuit for detecting a variation in the power or current absorbed by an electronic circuit under test is disclosed. The circuit includes an input terminal adapted to receive a pulse-width modulation control signal, a resistor having a first terminal connected to the input terminal, and a capacitor having a first terminal connected to a second terminal of the resistor. The output terminal is adapted to generate an output signal as a function of the value of the voltage drop at the ends of the capacitor, said output signal being representative of a variation of the pulse width of the pulse-width modulation control signal. The variation of the pulse width is a function of the power or current absorbed by the electronic circuit under test.

Abstract: Apparatus and method for gear tooth alignment by strain in order to minimize unbalanced loading of the gear teeth of a two stage parallel or branched gear system. Two hardened and separately ground gears are fitted with an easy fit between the shaft of one gear and the bore of the other and welded to make a compact cluster. The welded area develops a weakness resulting from being annealed due to heating in the welded zone. After assembling, the output shaft is locked to the gear train structure, the input gear is loaded slightly greater than the designed maximum load, causing the stress to exceed the yield point at the annealed welded area. A permanent deformation of all gears results with work hardening of the welded area during one cycle and a desired permanent repositioning of the teeth occurs resulting in reorientation of the gear teeth of the gears in mesh in the cluster.
