  • Patent number: 10777956
    Abstract: Oscillation mitigation circuits are implemented in a system for supplying electric power to load circuit boards, for example, load circuit boards entirely immersed into a bath of dielectric heat transfer fluid. The oscillation mitigation circuits can be used to protect the load circuit boards, including the connectors mounted on these load circuit boards, from an anomalous behavior of the electric power. The oscillation mitigation circuits are coupled between wire bundles forming a portion of the electric power supply and the connectors mounted on the load circuit boards.

  • Patent number: 9207042
    Abstract: Apparatus and methods relating to a device for increasing the firing rate of a firearm that may be retrofit to an existing firearm. The device includes an anchor mechanism affixed to a slidable butt stock of the firearm and also includes a finger hold connected to the anchor mechanism that translates forward to remove a user's finger from the trigger and translates backward to allow the user's finger to activate the trigger and fire the firearm.

  • Patent number: 7419831
    Abstract: A method for calibrating an analysis instrument, e.g., a gas chromatograph, for water analysis that includes four steps. The first step is to continuously remove water from a liquid that contains water to produce a liquid containing a reduced amount of water such as by membrane pervaporation. The second step is to analyze the liquid containing a reduced amount of water for water by a reference water analysis method such as by Karl Fischer titration. The third step is to analyze the stream of liquid containing a reduced amount of water using the instrument to be calibrated, e.g., a gas chromatograph having a helium photoionization pulse discharge detector. The fourth step is to calibrate the instrument using the analysis of the second step. In a related embodiment, a system for normal phase chromatography.
