Title: Tubular submucosal graft constructs
Inventor: PATEL UMESH H
IPC: A61F2/06
Filed: 1997-12-10
Granted: 2007-02-06
Abstract: An easy-to-produce and mechanically strong tube of an implantable submucosal tissue has been developed which is manufactured in any desired length, wall thickness, or diameter. The construct produced by the method of the invention may be used as grafts for arteries, veins, ureters, urethras, shunts, or in any application where a compliant, tissue-compatible tube is needed. The manufacture of the submucosal tissue prostheses generally involves wrapping a first sheet of submucosal tissue (60) and a second sheet of submucosal tissue (70) around a mandrel (50), wherein the first end (74) and the second opposite end (76) of the second sheet of submucosal tissue (70) are sutured together with sutures (78). The submucosal tissue is compressed and dried on the mandrel (50) before removing the construct by pulling on a first end (54) and a second end (56) of a water permeable tape to unwind the tape and thus release the construct for eventual use.

Title: Dual trailer
Inventor: HICKS W GLEN
IPC: B60G5/00
Filed: 1998-09-04
Granted: 2007-11-20
Abstract: A dual dump trailer assembly is provided which provides for operating two end dump trailers with a single cab. The operation is possible by use of a movable pedestal having a fifth wheel mounted on the forward end dump trailer. The pedestal is in the rearward, trailing position to attach the rearward end dump trailer at the fifth wheel on the pedestal for towing. Upon arrival at the dump site, the rearward end dump trailer can be dumped and then detached from the forward end dump trailer. The pedestal mounting the fifth wheel will move forward to a forward, dumping position, permitting the contents of the forward end dump trailer to be dumped.

Abstract: A method for production of simultaneous lap and butt joints directs electromagnetic radiation (12) through a radiation transmitting material (40) to an absorbing material (44a, 44b, and 44c) that absorbs radiation (12) with the generation of heat. The heat provides sufficient molten material in interfaces (50a, 50b and 50c) to fuse and bond: 1) pipe ends (14, 24) to each other in a butt joint (22; 2) pipe end portion (16) to sleeve (40) in a lap joint (28a), and 3) pipe end portion (26) to sleeve (40) in a lap joint (28b). Use of a sufficiently clear material for sleeve (40) allows visual inspection of joints (22, 28a, and 28b). Butt joint (22) can be formed by conductive heating without absorbing material (44a) to provide a smooth interior bore useful for transporting high purity fluids without risk of absorbent contamination or debris and organism collection in gaps found in previous joining techniques.

Abstract: The orthosis is formed of a monolithic semi-rigid resilient shell and is engaged inside a footwear to conformingly fit against the plantar portion of a person's foot, extending from the anterior metatarsal region to the heel portion. The rear end portion of the orthosis has inner and outer rearwardly-extending resiliently deformable arms defining a rearwardly-opened notch therebetween for partial engagement of the heel in the notch. Upwardly arcuate inner and outer flanges are provided respectively on the inner and outer arms, opposite the notch, for forming a cup-like seat for the heel. The front end portion of the orthosis engages the metatarsal plantar region of the foot, and has a sinuous front edge having five frontwardly-facing arcuate concavities each for registering engagement thereagainst of a corresponding one of the five metatarsal anterior portions of the user's foot. The combination of the independently deformable arms forming a cup-like seat with the front edge concavities allow stabilization and positional self-adjustment of the orthosis inside the footwear, to compensate accidental positional shifts of the orthosis in the footwear.

Title: Spinal fixation system
Inventor: MULLANE THOMAS S
IPC: A61B17/70
Filed: 2000-01-24
Granted: 2008-04-01
Abstract: An adjustable spinal fixation system comprises a collection of anchoring assemblies attached, via a variety of connectors, to spine-stabilizing rods. The anchoring assemblies include a linking member attached in a ball-and-socket fashion to a bone-engaging member that is adapted to engage a spinal bone of a patient.  The linking member joins one of the included connectors to an associated bone-engaging member. The connectors are selectively attached to one of the stabilizing rods. The anchoring assemblies each include a support collar and a retention collet that cooperate to allow adjustment of the bone-engaging member and corresponding connector during surgery. When surgery is complete, a securing nut and locking bolt cooperate with the support collar and retention collet to maintain the relative position of the entire fixation system, preventing unwanted movement between the system components.  In one embodiment, the connectors are multi-piece units that may be added or removed without disturbing adjacent connectors.

Title: Quantization in perceptual audio coders with compensation for synthesis filter noise spreading
Inventor: UBALE ANIL WAMANRAO
IPC: G10L19/032
Filed: 2000-04-10
Granted: 2008-07-29
Abstract: Many perceptual split-band coding systems that use analysis and synthesis filters assume the quantization noise introduced by quantizing split-band signals is substantially the same as the noise that results in the output signal obtained by applying the synthesis filters to the quantized split-band signals. In general, this assumption is not true because the synthesis filters modify or spread the quantization noise. A theoretical framework for deriving an optimum bit allocation that accounts for synthesis-filter noise spreading is disclosed. In concept, the problem of finding an optimal bit allocation can be expressed as a linear optimization problem in a multidimensional coordinate space. Simplified processes derived from this theoretical framework are disclosed that can obtain near-optimal solutions using modest computational resources.
