Title: Source coding to provide for robust error recovery during transmission losses
Inventor: GHOSAL SUGATA
IPC: H04N19/895
Filed: 1998-10-22
Granted: 2007-12-18
Abstract: A method for source coding a signal is described. In particular, a signal comprising multiple signal elements is processed. Each signal element is encoded to form a bitstream (130). The bits within a given bitstream are distributed across different bitstreams (140). Thus, the parameters describing components of the segment elements are distributed across the different bitstreams. The grouping and distributing steps result in error distribution across multiple levels of image reconstruction. Another method is also described for a multiple level shuffling process. A signal is defined as multiple levels wherein each level comprises a frame, a plurality of pixels, and a plurality of bits. In one embodiment, shuffling occurs on each level and between levels. Multiple level shuffling causes burst error loss to be distributed across multiple levels thereby facilitating image reconstruction of those areas of the image in which the loss occurred.

Abstract: The invention is a mechanical seal as-sembly for use between a stationary body and a rotating shaft. The seal assembly in-cludes a stationary element, a rotating bias-ing element and a rotating tensioning ele-ment. The rotating biasing element is sealed to the rotating shaft utilizing an o-ring seal.     The tensioning member is rigidly mounted to said shaft using an interference fit backed up by set screws or the equivalent. The stationary assembly is centered about the shaft and rigidly fastened to the stationary body. Either the stationary element or the rotating follower element may hold pack-ing in a radial packing groove, as a sealing medium. An axial biasing force provided by coil springs (or other compressive means) on the periphery of the rotating follower plate and secured by the rotating tensioning ele-ment insures intimate contact of the packing medium to the stationary element and rotat-ing biasing element sealing face, thus pro-viding a fluid tight seal. In the preferred embodiment, the elements are provided as a fully split design, enabling this seal to be assembled on a rotating shaft without the ne-cessity of access to the end of the shaft.

Abstract: The invention provides near-term customized ablation capabilities for treatment of corneal irregularities by ablating laterally offset refractive therapy profiles. These treatment profiles may, when centered on the eye (E), be suitable for treatment of standard refractive errors such as myopia, hyperopia, and cylindrical astigmatism. By selectively offsetting one or more of these ablation profiles at selected points across the corneal surface (C), the laser system (14) can reduce refractive errors resulting from corneal irregularities such as irregular astigmatism, corneal steepening in one quadrant, asymmetrical astigmatism, irregularities inadvertently produced by a prior refractive treatment (such as radial keratotomy incisions, a de-centered ablation, or the like), granular dystrophy, diffuse, asymmetric warpage as a result of post-corneal transplants, bilateral keratoconus, penetrating keratoplasty, or the like.

Title: Method and arrangement for inspection and requalification of lined vehicles used for transporting commodities and/or hazardous materials
Inventor: BARICH DANIEL
IPC: G01M99/00
Filed: 2000-09-29
Granted: 2010-01-26
Abstract: A test procedure for in-specting a vehicle (100) adapted to transport commodities. This procedure includes the steps of inspecting (S500) a lining disposed in a tank of a tank car and comparing (S510) crack, blister, and corrosion conditions on the liner with predetermined models. These predetermined models convey a discrete range of severity levels of cracks, blisters, and corrosion conditions and permit determination (S520) of severity level for the compared condition(s). The severity level for the condition is then documented (S530). Standardization of inspection findings facilitates trending analysis of each tank car or vessel lining to determine when requalification of a given lining should be carried out, thus improving the safety with which commodities (including regulated hazardous materials) are shipped and stored.
