  • Patent number: 11926398
    Abstract: A diving helmet apparatus includes a diving helmet that is based on a 98th percentile anthropomorphic head form. The helmet is relatively smaller and lighter than convention diving helmets. The center-of-gravity and center-of-buoyancy of the helmet are co-located to reduce diver fatigue. The apparatus has unique neck dam latch devices that use cam mechanisms. The neck dam and the opening in the helmet that receives the diver's head both have a substantially oval shape that contributes to a significant reduction in the volume of the helmet. The apparatus also uses unique face mask latch devices. The neck dam and face mask latch devices allow a diver to easily secure and remove the helmet and face mask without the assistance of dive tenders.

  • Patent number: 11926507
    Abstract: A hook assembly includes a first hook having a first open end and a second hook having a second open end. The first hook is parallel to the second hook where the first open end is adjacent to the second open end. Extensions extend from each of the first hook and the second hook. The extensions extend perpendicular to a hook plane of the first hook and the second hook members. The first hook is a mirror image of the second hook. A hinge connects the first hook to the second hook. The hinge is located at an opposite end of the hook from where the extensions are located. A resilient member exerts a constant force at the hinge to bias the first hook and the second hook toward an open position.

  • Patent number: 11927433
    Abstract: Embodiments are directed to direct impingement cook-off mitigation systems. As assembled, a munition fuzewell is torqued into the aft end of a munition. During a cook-off event, the expanding gases from the booster energetic will burn instead of detonating. The hot expanding booster gases are vented to the munition's main fill energetic causing the main fill energetic to burn concurrently with the booster energetic. The combined expanding gases from both the booster and main fill energetics are then vented through longitudinal vents.

  • Patent number: 11920035
    Abstract: This disclosure concerns electrically conducting poly(pyrazoles). The concept of oligomerizing and polymerizing substituted aminopyrazole derivatives combined with a monomer activation procedure involving base-mediated conversion of the protonated pyrazole ring nitrogen to amine salt was developed. This disclosure concerns the specific chemistries needed for the synthesis of a pyrazole monomer used in the polymer synthesis. The procedure used for blending the novel polypyrazoles with other compounds needed for construction of solar cells for testing was developed. This disclosure concerns the concept of using these types of heteroatom-rich, electron-deficient oligomers or polymers as n-dopable or p-dopable electron acceptors in photovoltaic cells. This disclosure concerns synthesizing the starting monomer compounds and polypyrazoles.

  • Publication number: 20240072889
    Abstract: Methods, apparatus, and systems are disclosed for implementing a fiber optic reflectance standard (FORS) for testing and/or calibration of a test instrument (TI), which provides a traceable means to calibrate the making optical return loss measurements (ORLM). The apparatus for implementing the FORS may include an optical splitter, first and second optical inputs coupled to the optical splitter, and an optical fiber having first and second ends, and coupled to the optical splitter at the first end of the optical fiber. Furthermore, the apparatus includes an attenuator (e.g., a mechanical attenuator) configured to contain a portion of the optical fiber between the first and second ends and selectively attenuate optical signal gain of the optical fiber. The testing and/or calibration results in an uncertainty that is at least four times better than a typical test instrument.

  • Publication number: 20240069125
    Abstract: Disclosed are apparatus and methods for sensing and measurement of magnetic fields that are insensitive to temperature, and respond linearly to the magnitude of the magnetic field. In particular, the apparatus and methods include the use of a resistance network including at least one fluorinated graphene foam (FGF) magnetoresistive device. Measurement of a voltage drop across at least one FGF magnetoresistive device is correlated to either merely the presence of a magnetic field or for measurement of at least a scalar magnitude value of the magnetic field. The use of FGF affords both temperature-insensitivity and linear magnetic field responsivity.
