Patent number: 11837764Abstract: Methods and devices and aspects thereof for generating power using PEM fuel cell power systems comprising a rotary bed (or rotatable) reactor for hydrogen generation are disclosed. Hydrogen is generated by the hydrolysis of fuels such as lithium aluminum hydride and mixtures thereof. Water required for hydrolysis may be captured from the fuel cell exhaust. Water is preferably fed to the reactor in the form of a mist generated by an atomizer. An exemplary 750 We-h, 400 We PEM fuel cell power system may be characterized by a specific energy of about 550 We-h/kg and a specific power of about 290 We/kg. Turbidity fixtures within the reactor increase turbidity of fuel pellets within the reactor and improve the energy density of the system.Type: GrantFiled: March 4, 2020Date of Patent: December 5, 2023Assignee: Intelligent Energy Inc.Inventors: Jason L. Stimits, Russell Barton, Douglas A. Knight, Iain M. Fraser, Hao Huang, Sandra H. Withers-Kirby, Philbert C. Spencer, Piotr Marcin Kleszyk, Hossein Ostadi

Publication number: 20230350266Abstract: We utilize high-quality-factor (high-Q) metasurfaces patterned either in or adjacent to electro-optical or thermo-optical materials such as lithium niobate, barium titanate, or thermally-sensitive polymers. The metasurface includes nanoantennas that act as dipole emitters; the particular structure and arrangement of nanoantennas can steer light to particular directions or focus light, The electromagnetic metasurface supports one or more guided mode resonances. The metasurface also includes a perturbation superposed on the metasurface features and configured to couple free-space radiation to the guided mode resonances.Type: ApplicationFiled: September 15, 2021Publication date: November 2, 2023Inventors: Jennifer A.

Publication number: 20230299551Abstract: Self-isolated lasers are provided by using a chiral metasurface in combination with a spin-selective gain medium and symmetry-breaking (i.e., not linearly polarized) optical pumping. In preferred embodiments the chiral metasurface is resonant, thereby proving an integrated optical resonator to support lasing. The chiral metasurface can be the spin-selective gain medium, or it can be formed on a surface of the spin-selective gain medium, or it can be distinct from the spin-selective gain medium.Type: ApplicationFiled: August 16, 2021Publication date: September 21, 2023Inventors: Jefferson Dixon, Mark Lawrence, David Russell Barton III, Jennifer A.

Patent number: 11487180Abstract: A metasurface optical device composed of three stacked dielectric layers which form an anti-reflective structure for wavelengths in a predetermined operational wavelength range within the visible spectrum. The anti-reflective structure contains a rectangular lattice of rhombohedral perturbations that produce guided-mode resonances within the predetermined operational wavelength range. The guided-mode-resonant dielectric metasurface device is capable of detecting by colorimetric readout the presence and orientation of a linearly birefringent anisotropic medium, such as a fibrous tissue, positioned above the stacked dielectric layers.Type: GrantFiled: September 24, 2020Date of Patent: November 1, 2022Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Jennifer A.

Patent number: 10199670Abstract: A device includes a case having a surface with a perforation and a first cavity containing a gas generating fuel. A first membrane is supported by the case inside the first cavity. The first membrane has an impermeable valve plate positioned proximate the perforation. The first membrane is water vapor permeable and gas impermeable and flexes responsive to a difference in pressure between the cavity and outside the cavity to selectively allow water vapor to pass through the perforation to the fuel as a function of the difference in pressure. A second membrane that is water vapor permeable gas impermeable is coupled between an outside of the case exposed to ambient atmospheric gas and the valve plate creating a reference pressure second cavity configured to reduce the effects of ambient pressure transients on the difference in pressure. A fuel cell membrane may be included in the device to produce electricity.Type: GrantFiled: April 8, 2016Date of Patent: February 5, 2019Assignee: Intelligent Energy LimitedInventors: Steven J.
