  • Patent number: 11971238
    Abstract: This disclosure describes systems, methods, and apparatus for detecting and displaying a number of rounds in a firearm magazine comprising a maximum number of N rounds. The magazine may comprise a follower, magnets on the follower, and <N magnetic switches arranged along a path of the magnets when the follower moves along a length of the magazine, the switches configured to activate based on a magnetic field exceeding a threshold, and a first antenna arranged on an inside of the magazine and parallel to a firing direction of the firearm, and configured to wirelessly transmit a round count indication to a second antenna on the firearm, the round count indication based on the round count data, the second antenna affixed to an inside of a magazine well of the firearm and mostly overlapping with the first antenna.

  • Patent number: 8572817
    Abstract: A rigid U-shaped structure sized to be closely received on the tip end of the transfer hook. One side of the U-shape of the structure is closed. A padeye is rigidly attached to the end curved portion of the U-shape of the structure. Means for holding the U-shaped structure in position on the tip end of the hook is provided. The holding means may be threaded bores through one or both sides of the U-shaped structure that allow bolts to be threaded through the holes such that they create sufficient friction against the tip end of the transfer hook to hold the U-shaped structure in position. The holes through the U-shaped structure may be unthreaded with threaded nuts rigidly attached to the U-shaped structure such that the nuts are aligned with the holes to allow bolts to exert pressure against the tip end of the transfer hook in the same manner to hold the U-shaped structure in position on the transfer hook.

  • Patent number: 7614209
    Abstract: A mechanically releasable shackle pin arrangement that is readily operated by an ROV and is not affected by the hydrostatic pressures encountered at depth. A shackle body having two ends has a shackle pin received through bores at one end of the shackle body. A shackle nut threaded on the shackle pin secures the shackle pin in an installed position through the bores in the shackle body. An anti-rotation link plate is attached to the shackle body. The anti-rotation link plate extends to one end of the side plate. The shackle pin extends through bores at one end of the shackle body and the anti-rotation link plate and is secured in its installed position by a shackle nut threaded on the shackle pin. Means for preventing rotation of the shackle nut and loss of the shackle nut is provided on the anti-rotation link plate such that the shackle pin can be removed by a remotely operated tool on an ROV at depth to release a load without the need for hydraulics on the shackle assembly.

  • Publication number: 20070178658
    Abstract: A method is provided for making a device comprising aligned semiconducting nanoparticles and a receptor substrate comprising the steps of: a) aligning a plurality of first semiconducting nanoparticles; b) depositing the aligned first semiconducting nanoparticles on a first donor sheet; and c) transferring at least a portion of the aligned first semiconducting nanoparticles to a receptor substrate by the application of laser radiation. Typically, the semiconducting nanoparticles are inorganic semiconducting nanoparticles. The alignment step may be accomplished by any suitable method, typically including: 1) alignment by capillary flow in or on a textured or microchanneled surface; 2) alignment by templating on a self-assembled monolayer (SAM); 3) alignment by templating on a textured polymer surface; or 4) alignment by mixing in a composition that includes nematic liquid crystals followed by shear orientation of the nematic liquid crystals.

  • Publication number: 20060068519
    Abstract: A method of making an electronic device by (a) depositing a substantially nonfluorinated polymeric layer onto a dielectric layer using a plasma-based deposition technique selected from the group consisting of (i) plasma polymerizing a precursor comprising monomers, and (ii) sputtering from a target comprising one or more polymers of interpolymerized units of monomers, the monomers being selected from the group consisting of aromatic monomers, substantially hydrocarbon monomers, and combinations thereof; and (b) depositing an organic semiconductor layer adjacent to said polymeric layer.
