20120297335 | DOCUMENT GLANCING AND NAVIGATION - When viewing a document, a user may switch between detailed reading of the document, and glancing at the structure of the document, in a single smooth flow of actions. In one example, a document is shown with a navigation bar that has a thumb. Before the user clicks the thumb, the document is shown at its current position at a first zoom level. When the user clicks and holds the thumb, the current page of the document is shown at a second zoom level, which may be a full-page zoom level at which an entire page of the document fits in the viewing area. The user may drag the thumb, thereby changing the current page being shown at the second zoom level. When the use releases the thumb, the current page may be shown at the first zoom level. | 11-22-2012 |

20130152674 | GREASE TEST KIT AND METHODS OF TESTING GREASE - A kit for testing grease includes components for testing consistency, oil bleed characteristic and contamination. Consistency of the grease is tested by compressing a sample of the grease between two surfaces (e.g., glass plates), measuring the extent of spread, and comparing the measured spread to a calibrated reference. Oil bleed characteristic is tested by placing a quantity of the used grease on a test medium, heating the test sample, measuring a dimension of the grease quantity on the heated test sample, and determining the bleed characteristic of the used grease by comparing the dimension of the grease quantity to a reference. A contamination test may be performed by further compressing the consistency sample and inspecting the sample both by the naked eye and with a microscope. | 06-20-2013 |

20130329043 | TRANSMISSIONS OF IMAGES IN A REMOTE RECOGNITION SYSTEM - A method and apparatus for selective transmission of color information to a remote recognition system is provided herein. During operation, a central server may determine that at least one region in an image is ambiguously recognized, or unrecognized. In response, the central server will send a request for the image/video to be provided in color, or alternatively for a portion of the image/video to be provided in color. Because only selective images, or portions of images will be transmitted in color, the above transmission scheme enables reduction of bandwidth, and hence cost, required for transmitting images to the analytics server, without compromising the accuracy of the analytics. | 12-12-2013 |
