| 20100151285 | ANODE REACTIVE BLEED AND INJECTOR SHIFT CONTROL STRATEGY - A system and method for correcting a large fuel cell voltage spread for a split sub-stack fuel cell system. The system includes a hydrogen source that provides hydrogen to each split sub-stack and bleed valves for bleeding the anode side of the sub-stacks. The system also includes a voltage measuring device for measuring the voltage of each cell in the split sub-stacks. The system provides two levels for correcting a large stack voltage spread problem. The first level includes sending fresh hydrogen to the weak sub-stack well before a normal reactive bleed would occur, and the second level includes sending fresh hydrogen to the weak sub-stack and opening the bleed valve of the other sub-stack when the cell voltage spread is close to stack failure. | 06-17-2010 |

| 20090288035 | SCROLLABLE VIEWS IN A CLIENT/SERVER APPLICATION - Described herein is technology for, among other things, a method of displaying a number of views in response to user scrolling. A basic, generic view is initially rendered for display on a client. Subsequent views are rendered for display that tracks the scrolling. During the scrolling process, data is not requested from the server. Only data that is stored on the client device is used while scrolling. When the scrolling has deemed to have stopped, the client requests additional data from the server. This additional data is rendered for display and is also stored in the locally on the client. Subsequent views containing this data can be generated quickly because the data exists locally. Thereby, views can be quickly and smoothly scrolled through and will appear richer in content over time. | 11-19-2009 |
