Patent number: 8546002Abstract: A yeast biofilm microbial fuel cell has anode and cathode chambers, each containing an electrolyte medium, separated by a proton conducting membrane. A baker's yeast biofilm is induced to form on the anode under electrical poising. A method of making the MFC includes adding baker's yeast and yeast nutrient fuel source to the anode solution, connecting a resistor across the anode and cathode to enable current flow through the resistor for a selected time for poising the anode and formation of the anodic yeast biofilm, replacing the anode solution with a fresh quantity of yeast-free solution, adding fuel source to the solution, and continuing to run the MFC for a selected time under resistance. The steps of replacing the anode solution, adding fuel source and running the cell under load are repeated until the baker's yeast has formed a suitable anodic biofilm.Type: GrantFiled: October 26, 2009Date of Patent: October 1, 2013Assignee: Teledyne Scientific & Imaging, LLCInventors: Rahul Ganguli, Vivek Mehrotra

Patent number: 8356959Abstract: A biomimetic system for mitigating marine bio-fouling is disclosed which is based upon the sacrificial skin mechanism found in the pilot whale species. The anti-bio-fouling system is characterized by the continuous in-situ underwater formation of a conformal protective skin around a submerged object or structure and employs a circulatory system embedded in a diffuser layer conformably fitted and secured to the structure to controllably deliver a sacrificial skin-forming material to the structural surface. The system advantageously utilizes the unique chemical properties of the skin-forming material to alter the material's viscosity in response to contact with sea water such that the material is uniformly distributed over the structure surface by a self-diffusion process, notwithstanding structural configuration or gravitational orientation, thus forming a stabilized waterproof layer or sacrificial skin.Type: GrantFiled: October 1, 2009Date of Patent: January 22, 2013Assignee: Teledyne Scientific & Imaging LLCInventors: Rahul Ganguli, Vivek Mehrotra

Patent number: 8054763Abstract: A method, system and computer program product for migrating at least one switch in a storage area network is disclosed. The migration is done by analysing the I/O traffic to identify patterns in the I/O traffic of the switch; forecasting future I/O workload of the switch based on one or more identified patterns in the I/O traffic, determining appropriate timing for migration based on the identified patterns and administrator inputs; processing the storage area network configuration data to identify the storage network physical and logical access paths to the or each selected switch to create a first connectivity map; generating a second connectivity map based on the first connectivity map and administrator inputs; and migrating the or each switch migration based on the second connectivity map and the appropriate timing. The migration may comprise routing the I/O traffic from the switch to be migrated to the alternate switches in the storage area network.Type: GrantFiled: May 15, 2009Date of Patent: November 8, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Vivek Mehrotra, Satish Kumar Mopur, Saikat Mukherjee, Satyaprakash Rao, Gunalan Perumal Vijayan, Sridhar Balachandriah
