20090311587 | Flexible Energy Storage Devices - A flexible energy storage device comprising a flexible housing; an electrolyte contained within the housing; an anode and cathode comprise a current collector and anode/cathode material supported on the current collector. The current collector comprising a fabric substrate ( | 12-17-2009 |
20110097624 | REDOX ELECTRODES FOR FLEXIBLE DEVICES - Flexible electrodes comprising: a fabric substrate; a conductive polymer, copolymer or mixture of conductive polymers comprising a first component which has high specific electrochemical capacitance, and a second component which has a lower electrochemical capacitance, lower molecular density, and greater electrical conductivity compared to the first component; and a counterion stable to lithium are described. The first component may be a polymer such as polyaniline or polypyrrole, and second component may be a polymer such as polythiophene or polyEDOT. Copolymers, and polymers formed from co-monomer of these monomer units are also described. The electrodes are used in flexible devices such as flexible energy storage devices. | 04-28-2011 |

20140060976 | STAIRLIFTS - The invention provides a levelling system for the chair of a stairlift, a characteristic feature of the system being the provision of a safety back-up or locking mechanism that will lock the position of the chair in the event of failure within the levelling drive. This locking mechanism preferably includes a locking wheel that is in partial mesh with a geared wheel forming part of the levelling drive. In the event of failure within the drive the locking wheel meshes to lock the position of the chair. | 03-06-2014 |
