Automated mobile compressed hydrogen fuel source management for mobile power generation applications
Patent number: 11302941Abstract: 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.Type: GrantFiled: January 14, 2020Date of Patent: April 12, 2022Assignee: GM Global Technology Operations LLCInventors: Raffaello Ardanese, Kristopher A.

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
