Patents by Inventor Greg Alden Lloyd

Greg Alden Lloyd 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).

  • Publication number: 20210376506
    Abstract: Systems for interfacing a printed circuit board assembly (PCBA) adapter module to a receiver housing are provided. The receiver housing may have a first interface mounted on the receiver housing via a first mount and the PCBA adapter module may have a second interface mounted on the adapter module via a second mount. One of the interfaces has a protruding feature that aligns the interfaces when matingly engaged, while the other interface has a centering hole opposite the protruding feature. The first centering hole is enlarged with respect to an axis of an insertion-angle plane such that the protruding feature substantially clears the centering hole without causing either interface to exceed a limit of free-play between that interface and its respective mount.

  • Patent number: 6218035
    Abstract: A proton exchange membrane fuel cell power system for producing electrical power is described and which includes a plurality of discrete fuel cell modules having at least two membrane electrode diffusion assemblies, each of the membrane electrode diffusion assemblies having opposite anode and cathode sides; a pair of current collectors are individually disposed in juxtaposed ohmic electrical contact with opposite anode and cathode sides of each of the membrane electrode diffusion assemblies; and individual force application assemblies apply a given force to the pair current collectors and the individual membrane electrode diffusion assemblies. The proton exchange membrane fuel cell power system also includes an enclosure mounting a plurality of subracks which receive the discrete fuel cell modules. Additionally, a control system is disclosed which optimizes the performance parameters of the discrete proton exchange membrane fuel cell modules.
