Patents by Inventor Craig Michael Spencer

Craig Michael Spencer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11165232
    Abstract: A housing assembly is adapted for housing fully pre-wired printed circuit boards populated with diverse electrical components. The housing assembly includes multiple nipples and an optimized geometry for mounting to or mounting within commonly available conduit-related fixtures in a variety of installation configurations. These installation configurations allow for simpler wire routing where voltage separation is required, for greater accessibility to gang junction box cover plates on gang junction boxes to which the housing assembly is mounted, and for more installation options for wide range of common gang junction boxes as compared to existing housings.
    Type: Grant

  • Patent number: 6930434
    Abstract: The present invention increases the life of a pole crossover while minimizing the need for timely inspections and costly replacements. The present invention splits the pole crossover band 4 at one or more locations along its circumference and then joins the multiple arcs with a flexible member 10, such as an omega shaped bow. As deflection related stresses 8 increase, the circumference of the pole crossover band, the flexible member 10 allows for a natural expansion point in the otherwise rigid material. This relieves stresses that would otherwise be transferred to the connection point 6 between the pole crossover and the generator windings that can cause cracking and eventually generator failure.
