Patents by Inventor Lawrence Ludwig

Lawrence Ludwig 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: 11930613
    Abstract: An electronic assembly includes a chassis having electronic module mounting positions. The electronic assembly also includes a respective electronic module received in each electronic module mounting position and having a module cooling gas passageway. Each electronic module has a module glide surface. The electronic assembly includes a respective sealing retainer coupled between the chassis and each electronic module. The sealing retainer has a cooling gas passageway aligned with a chassis cooling gas passageway and the module cooling gas passageway. The sealing retainer includes a retainer body having a retainer glide surface, and a gas sealing gasket carried by the retainer body. The module glide surface and the retainer glide surface have respective cooperating features so that the respective electronic module is maintained in spaced relation from the sealing gasket as the respective electronic module is slidably inserted into a seated position.

  • Patent number: 8034650
    Abstract: A sensor for selectively determining the presence and measuring the amount of hydrogen in the vicinity of the sensor. The sensor comprises a MEMS device coated with a nanostructured thin film of indium oxide doped tin oxide with an over layer of nanostructured barium cerate with platinum catalyst nanoparticles. Initial exposure to a UV light source, at room temperature, causes burning of organic residues present on the sensor surface and provides a clean surface for sensing hydrogen at room temperature. A giant room temperature hydrogen sensitivity is observed after making the UV source off. The hydrogen sensor of the invention can be usefully employed for the detection of hydrogen in an environment susceptible to the incursion or generation of hydrogen and may be conveniently used at room temperature.
