20100295868 | IMAGE PROCESSING FOR HANDHELD SCANNER - A computer peripheral that may operate as a scanner. The scanner captures image frames as it is moved across an object. The image frames are formed into a composite image based on computations in two processes. In a first process, fast track processing determines a coarse position of each of the image frames based on a relative position between each successive image frame and a respective preceding image determine by matching overlapping portions of the image frames. In a second process, fine position adjustments are computed to reduce inconsistencies from determining positions of image frames based on relative positions to multiple prior image frames. The peripheral may also act as a mouse and may be configured with one or more navigation sensors that can be used to reduce processing time required to match a successive image frame to a preceding image frame. | 11-25-2010 |
20100296129 | AUTOMATIC SIZING OF IMAGES ACQUIRED BY A HANDHELD SCANNER - A computer peripheral that may operate as a scanner. The scanner captures image frames as it is moved across an object. The image frames are formed into a composite image based on computations in two processes. In a first process, fast track processing determines a coarse position of each of the image frames based on a relative position between each successive image frame and a respective preceding image determine by matching overlapping portions of the image frames. In a second process, fine position adjustments are computed to reduce inconsistencies from determining positions of image frames based on relative positions to multiple prior image frames. As additional image frames are added to the composite image, the size and format of the composite image may be automatically adjusted to facilitate ease of use. | 11-25-2010 |
20100296131 | REAL-TIME DISPLAY OF IMAGES ACQUIRED BY A HANDHELD SCANNER - A computer peripheral that may operate as a scanner. The scanner captures image frames as it is moved across an object. The image frames are formed into a composite image based on computations in two processes. In a first process, fast track processing determines a coarse position of each of the image frames based on a relative position between each successive image frame and a respective preceding image determine by matching overlapping portions of the image frames. In a second process, fine position adjustments are computed to reduce inconsistencies from determining positions of image frames based on relative positions to multiple prior image frames. As a result, a composite image of an object being scanned may be presented in real time to a user, providing a user feedback or portions of the object that have been scanned and those that have not. | 11-25-2010 |
20100296133 | MODE SWITCHING IN A HANDHELD SCANNER - A handheld device that may operate as a scanner, computer mouse or as a camera. In the scanner mode, the device captures image frames as it is moved across an object. The image frames are formed into a composite image based on computations in two processes. In a first process, fast track processing determines a coarse position of each of the image frames based on a relative position between each successive image frame and a respective preceding image determine by matching overlapping portions of the image frames. In a second process, fine position adjustments are computed to reduce inconsistencies from determining positions of image frames based on relative positions to multiple prior image frames. A control mechanism, such as a button on the device can be used to switch between the scanner and mouse modes. When the device is lifted, it may switch to the camera mode. | 11-25-2010 |
20140292770 | DISPLAY WITH ROBOTIC PIXELS - Techniques are disclosed for controlling robot pixels to display a visual representation of an input. The input to the system could be an image of a face, and the robot pixels deploy in a physical arrangement to display a visual representation of the face, and would change their physical arrangement over time to represent changing facial expressions. The robot pixels function as a display device for a given allocation of robot pixels. Techniques are also disclosed for distributed collision avoidance among multiple non-holonomic robots to guarantee smooth and collision-free motions. The collision avoidance technique works for multiple robots by decoupling path planning and coordination. | 10-02-2014 |

20140045413 | EXCHANGEABLE ABRASIVE MEANS FOR AN ABRASION APPLIANCE HAVING A SUCTION EXTRACTION ARRANGEMENT - An exchangeable abrasive mechanism or disc for use on abrasive-mechanism carriers having suction holes includes a plurality of through openings that each have a centroid. The through openings are differentiated into three groups that differ in the radial disposition of the centroids. A first group comprises at least one, but not more than four, through openings of a first cross section. At least two of the through openings of the first group are disposed on a first circumcircle diameter that is substantially identical to one of the hole-circle diameters such that, when the abrasive mechanism is correctly disposed on an abrasive-mechanism carrier, they are in direct alignment with and can overlap, two corresponding suction holes. A second group of through openings of a second, preferably smaller, cross section, comprises at least four through openings that are disposed on a second circumcircle diameter that differs from the first circumcircle diameter. | 02-13-2014 |
20140057539 | TOOL UNIT - A tool unit includes at least one basic body and at least one information element. The at least one basic body includes at least one fastening region configured, at least partially, to couple to a tool receiver of at least one hand-held power tool. The at least one basic body also includes at least one working region configured, at least partially, to work at least one workpiece when in an operating state. The at least one information element includes, at least partially, a material relief in the basic body. | 02-27-2014 |
