Patent number: 8986860Abstract: A subgasket for a fuel cell is provided. The subgasket includes a barrier layer having an elongate primary seal formed thereon. The seal has at least one inwardly extending baffle adapted to militate against a reactant bypass flow in the fuel cell. A fuel cell and fuel cell stack having the subgasket are also provided.Type: GrantFiled: April 22, 2008Date of Patent: March 24, 2015Assignee: GM Global Technology Operations LLCInventors: Saurabh Vyas, Jeffrey A. Rock, Eric J. Connor, Daniel P. Miller

Patent number: 8846265Abstract: A UEA for a fuel cell having an active region and a feed region is provided. The UEA includes an electrolyte membrane disposed between a pair of electrodes. The electrolyte membrane and the pair of electrodes is further disposed between a pair of DM. The electrolyte membrane, the pair of electrodes, and the DM are configured to be disposed at the active region of the fuel cell. A barrier film coupled to the electrolyte membrane is configured to be disposed at the feed region of the fuel cell. The dimensions of the electrolyte membrane are thereby optimized. A fuel cell having the UEA, and a fuel cell stack formed from a plurality of the fuel cells, is also provided.Type: GrantFiled: August 5, 2013Date of Patent: September 30, 2014Assignee: GM Global Technology Operations LLCInventors: Matthew J. Beutel, Saurabh Vyas, Ronald L. James, Steven G. Goebel

Patent number: 8761476Abstract: A method of detecting a skin condition may include employing a multiband hyperspectral sensor to obtain multi-spectral data, employing the multi-spectral data to map constitutive skin parameters to corresponding spectral signatures via a forward model that enables generation of a set of samples including a plurality of parameters mapped to a plurality of spectral signatures, utilizing the set of samples to employ machine learning to generate an inverse model to enable mapping of a spectral signature of skin of a patient to corresponding skin parameters, estimating constitutive skin parameters of the skin of the patient based on the inverse model, and determining a distribution of the constitutive parameters for one or more skin locations.Type: GrantFiled: September 25, 2012Date of Patent: June 24, 2014Assignee: The Johns Hopkins UniversityInventors: Philippe M. Burlina, Amit Banerjee, Saurabh Vyas, Luis Garza
