20090244300 | METHOD AND APPARATUS FOR MOTION INVARIANT IMAGING - Object motion during camera exposure often leads to noticeable blurring artifacts. Proper elimination of this blur is challenging because the blur kernel is unknown, varies over the image as a function of object velocity, and destroys high frequencies. In the case of motions along a 1D direction (e.g. horizontal), applicants show that these challenges can be addressed using a camera that moves during the exposure. Through the analysis of motion blur as space-time integration, applicants show that a parabolic integration (corresponding to constant sensor acceleration) leads to motion blur that is not only invariant to object velocity, but preserves image frequency content nearly optimally. That is, static objects are degraded relative to their image from a static camera, but all moving objects within a given range of motions reconstruct well. A single deconvolution kernel can be used to remove blur and create sharp images of scenes with objects moving at different speeds, without requiring any segmentation and without knowledge of the object speeds. | 10-01-2009 |

20150081472 | Computational Size Selection For Off The Shelf Garments - Computational systems may be provided to assist with compression garment recommendations. A measurement of a person's body part may be received, and a compression expected to be applied may be computed. The expected compression may be based upon an arm measurement and upon a known relationship between a size of the garment, such as a stretched circumference, and the compression applied to an object that stretches the garment to that circumference. Graphs and formulas may be used to represent physical properties of a compression garment by assigning compression levels for ranges of relevant circumferences for a multitude of points along a limb. Information about needs of a patient, patient's condition, compression sensitivity, desired compression class, or desired use may be considered as part of a computational analysis to assist in fitting garments. The disclosed recommendation systems may assist clinicians, patients, consumers, or other users in selecting suitable off-the-shelf compression garments. | 03-19-2015 |
