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

Patent number: 6580733Abstract: Analog pulse position modulation of pulsed emission from a laser, which is actively and harmonically mode-locked. The laser requires: a body of an active gain medium; means for changing the gain as a function of a controllable parameter; harmonically and actively mode-locking the laser by fast periodic changes of said parameter; and superimposing slower changes on the parameter whereby the fast periodic parameter changes can be continuously shifted between the peak and the shoulder of the gain-vs-parameter curve. As proof of concept, electric control of the separation between two interleaved pulse trains from a far-infrared (1.5-4 THz) p-Ge laser, which is actively mode-locked by rf gain modulation at the second harmonic of the roundtrip frequency, is demonstrated by changing the electric bias at the rf contacts. A suggested application is telemetry using analog pulse position modulation.Type: GrantFiled: November 24, 1999Date of Patent: June 17, 2003Assignee: University of Central FloridaInventors: Robert E.
