Integral electric generator, multiplexer, data acquisition system

Abstract

An electric generator with winding and rotor design so that it powers and multiplexes several sensor inputs during rotor rotation. The rotor may be rotated by any means such as fluid (gas or liquid) or electric motors.

Description

Claims

1. A system comprising a generating means having a plurality of windings; a rotating means in said generating means being adapted for rotation such that voltage will be generated in said windings in a sequential manner; a plurality of gating means; a plurality of connecting means connected between said windings and gating means such that said gating means will be triggered in a sequential manner in accordance with the voltage induced in said windings; said windings are connected in pairs such that their voltages will add when presented to said connecting means; said windings are two pairs in number; said connecting means being two pairs of diodes each connected in series; said gating means consisting of first, second, third and fourth gating means each having a gate control terminal, an output terminal and an input terminal; said pairs of diodes being connected across said first and second gating means control terminals and said third and fourth gating means control terminals respectively; a common connection; and said pairs of windings being connected to a point between said pairs of diodes and said common connection.

2. A system as set forth in claim 1 further comprising a plurality of data information systems each having an output connected individually to the input terminals of said gating means; said gating means each producing an output between its output terminal and said common connection; said output terminal of each gating means being connected to a common output line; and said common output line having a voltage output which is representative of a selected one of said data systems output in accordance with the rotation of said rotating means.

3. A system as set forth in claim 2 wherein said gating means are amplifier means.

4. A system as set forth in claim 3 wherein said rotor means is a permanent magnet rotor and said winding means being mounted on a stator with each pair of windings being 180.degree. apart relative to said stator.
