| 20090244291 | DYNAMIC OBJECT CLASSIFICATION - A camera system comprises an image capturing device and an object classification module connected to the image capturing device. The image capturing device has a field of view and produces image data representing an image of the field of view. The object classification module is operable to determine whether or not an object in an image is a member of an object class. The object classification module includes N decision steps configured in a cascade configuration, wherein at least one of the N decision steps is operable to (a) accept an object as a member of the object class, (b) reject an object as a member of the object class, and (c) call on a next step to determine whether or not an object is a member of the object class. | 10-01-2009 |
| 20090245573 | OBJECT MATCHING FOR TRACKING, INDEXING, AND SEARCH - A camera system comprises an image capturing device, object detection module, object tracking module, and match classifier. The object detection module receives image data and detects objects appearing in one or more of the images. The object tracking module temporally associates instances of a first object detected in a first group of the images. The first object has a first signature representing features of the first object. The match classifier matches object instances by analyzing data derived from the first signature of the first object and a second signature of a second object detected in a second image. The second signature represents features of the second object derived from the second image. The match classifier determine whether the second signature matches the first signature. A training process automatically configures the match classifier using a set of possible object features. | 10-01-2009 |

| 20090242043 | HYDROGEN SUPPLY PRESSURE REGULATOR - Hydrogen gas flow from high pressure storage to a lower pressure hydrogen-using device is managed using one or more axial flow pressure regulators comprising a cup-shaped housing with an inlet for high pressure hydrogen gas at one end of the flow axis and a closure with a low pressure hydrogen outlet at the other end of the flow axis. A piston head with a piston stem are aligned on the flow axis and a hydrogen flow passage is formed up the stem and through the piston head to the hydrogen flow outlet. One or more combinations of a corrugated tubular bellows (or like expansive sealing vessel) with static seals attaching one bellows end to the piston stem or head and the other bellows end to the housing or closure are used to accommodate axial movement of the piston while isolating and containing hydrogen gas flow from a high pressure chamber at a flow entrance to the piston stem to a low hydrogen pressure chamber at the piston head and closure outlet. | 10-01-2009 |
| 20110012313 | SEAL PERFORMANCE FOR HYDROGEN STORAGE AND SUPPLY SYSTEMS - The performance and durability of static and dynamic seals for hydrogen storage and supply systems has been improved by utilizing a spring-energized and plastic coated radial seal in combination with at least a mating surface that has been treated by one of a variety of procedures. These procedures include applying to the mating surface a low-friction, hard, and hydrogen impervious coating, chemically polishing the mating surface, and electrochemically polishing the mating surface. Each of these procedures significantly reduces, on a microscopic scale, the surface roughness of the mating surface. The seal can thus form a tighter and more gas-tight seal with the smoother mating surface so as to decrease the loss of hydrogen gas across the seal. The smoother mating surface can also improve seal life by reducing seal surface wear. | 01-20-2011 |
