  • Patent number: 11302941
    Abstract: A pressure-based latching switch includes a shuttle valve, a first valve and a second valve. The shuttle valve may switch a fuel through one of a first port and a second port in response to a greater pressure of the fuel at the ports. The first valve may switch a fuel to the first port while a second pressure of the fuel at the second port is less than a second threshold pressure. The second valve may switch the fuel to the second port while a first pressure of the fuel at the first port is less than a first threshold pressure. The pressure-based latching switch may change the fuel supplied to the fuel cell system automatically from a first fuel tank to a second fuel tank in response to the first pressure of the fuel falling below the first threshold pressure.

  • Patent number: 11000229
    Abstract: In accordance with disclosed embodiments, there are provided systems, methods, and apparatuses for integrating a body joint rehabilitation regimen with a wearable movement capture device operable in conjunction with a cloud based computing environment. For instance, a wearable apparatus for monitoring activity of a body joint such as knee or elbow for monitoring rehabilitation and recovery after surgical procedures and after injury to the joint is disclosed. Such a wearable apparatus includes a wearable harness in which a first portion of the wearable harness includes an proximal strap to be positioned proximal to the body joint and in which a second portion of the wearable harness includes a distal strap to be positioned distal to the body joint, in which the wearable harness is positionable upon a patient's body at the body joint without occluding a surgical site of the patient.

  • Patent number: 10168002
    Abstract: Devices and methods for addressing permeation of a gas through a liner of a pressure vessel involve a porous layer between the liner and a composite shell of the pressure vessel around the liner. The porous layer provides fluid communication with atmosphere for gases that permeate through the liner. Such porous layers may be provided in a continuous wound set of fibers about the liner. Further, an inner composite structure may be provided between the liner and the porous layer to reduce the rate of permeation to the porous layer.

  • Patent number: 9920883
    Abstract: A composite fuel tank, formed by winding filaments or strips around a plastic liner and binding the material with a curable binder. Embedded within the wrapped material at predetermined depths from the surface which provides a color indication of the level of damage due to tears, gashes, cuts and the like. The color indicator is part of a visual inspection method to determine tank damage and the extent of repair necessary.

  • Publication number: 20170191622
    Abstract: A polar boss suitable for use in pressurized-gas assemblies. The polar boss includes a longitudinally extending part with a top surface with a recessed opening and a planar bottom surface. A channel extends through the polar boss, communicates with the recessed opening, and terminates at the bottom planar surface to serve as a passageway through the polar boss. A circular groove is provided on the planar bottom surface with inner and outer side walls, with helical threading provided on the inner and outer side walls.

  • Publication number: 20170156639
    Abstract: A system for and method of mapping and monitoring posture disclosed. The system includes sensor units that independently collect posture data corresponding to body locations or body positions on subjects and generate posture signals. The posture signals are wirelessly transmitted to one or more computers that are used to process the posture signals and generate posture feedback of the subjects in real-time. The sensor units are preferably accelerometer sensor units. Sensor units are assigned or learn the body locations or body positions, classify body locations or body positions, map and monitor posture, assign posture or activities of subjects and transmit the posture signals to the one or more computers by low-power radio transmitters to provide posture feedback. The system collectively is adaptive for mapping and monitoring posture from body locations or body positions corresponding to spines, arms, legs, necks, heads, thighs, hips, feet and hands of the subjects.

  • Patent number: 9568150
    Abstract: A pressurized-gas storage assembly has a liner defining a gas storage chamber and an end portion with a planar surface, with an access opening on the planar surface that is in fluid communication with the gas storage chamber. A raised circular ring extends from the planar surface and surrounds the access opening. The assembly also includes a polar boss having a longitudinally extending part that has a top surface with a recessed opening, and a planar bottom surface, with a channel extending through the polar boss to serve as a passageway through the polar boss. A circular groove is provided on the bottom flat surface of the polar boss, with the raised ring received inside the circular groove. An outer shell is provided around the entirety of the liner, with the outer shell having an edge-defining aperture that receives the polar boss.
