  • Method and apparatus for deriving power consumption information from the angular motion of a rotating disk in a watt hour meter
    Patent number: 5442281
    Abstract: An apparatus for recording information about the angular motion of a rotatable disk disposed in a first structure is provided. The disk has regions with differing properties with respect to electromagnetic energy. The apparatus includes first means for emitting a first sequence of electromagnetic energy pulses in a first direction toward the disk. The first emitting means are mounted on the first structure adjacent a first side of the disk. The apparatus also includes second means for emitting a second sequence of electromagnetic energy pulses in a second direction toward the disk, the second emitting means also being mounted on the first structure adjacent the first side of the disk. The first and second directions are such that the first and second sequences of electromagnetic energy pulses reflect from the first side of the disk in different areas, the areas being separated in the direction of rotation of the disk.
