Patent number: 10168002Abstract: 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.Type: GrantFiled: November 3, 2015Date of Patent: January 1, 2019Assignee: Quantum Fuel Systems LLCInventor: Mark Leavitt

Publication number: 20170156639Abstract: 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.Type: ApplicationFiled: January 17, 2017Publication date: June 8, 2017Applicant: Gokhale Method EnterpriseInventors: Esther Gokhale, Mark Leavitt, Rachel Dreilinger, Björn Krüger, Jonas Müller

Publication number: 20140109823Abstract: A pressure indicator system is provided for use a gas storage container. The gas storage container has an interior that stores gas, and a housing having a cavity that opens to atmosphere and which communicates with the interior of the container. A piston or diaphragm communicates with a stem that extends through the cavity and into atmosphere, with the stem having a pressure indicator provided around an upper portion of the stem. A resilient element is retained in the cavity and normally biases the piston or diaphragm towards the interior of the container. The existence of pressure in the container opposes the normal bias of the resilient element to cause the stem and its pressure indicator to extend outside the cavity.Type: ApplicationFiled: October 22, 2012Publication date: April 24, 2014Applicant: QUANTUM FUEL SYSTEMS TECHNOLOGIES WORLDWIDE, INC.Inventor: Mark Leavitt
