Abstract: A sterile water generator (B) generates a stream of sterile water on demand. A water heater (130) heats incoming, unsterile water to a sufficient temperature to achieve sterilization of the water. The sterile water is then passed through a heat exhanger (110) which transfers excess heat from the sterile water to the incoming water. This reduces the energy consumption of the water heater and reduces the temperature of the sterile water ready for use. The sterile water is delivered to a site (A), at which the water is to be used, through a sterile water delivery pathway (C) to avoid recontamination of the water. A first portion (162) of the pathway is pre-sterilized by flowing steam or hot water, generated by the water heater, along the pathway (C). A second portion (212) of the pathway is sterilized with a liquid antimicrobial from the site. The first a nd second portions of the pathway have at least one common leg (164).

Title: Method and apparatus for forming a heart valve wireform
Inventor: LAM HUNG LY
IPC: A61F2/24
Filed: 2001-07-12
Granted: 2009-10-06
Abstract: A system and method for forming a three-dimensional wireform (20) for heart valves from a two-dimensional starting shape. The wireform has multiple arcuate cusps (22) and oppositely directed commissure tips therebetween, the cusps and commissure tips (24) being oriented generally in a tube about an axis. The two-dimensional wire has three cusps and two commissure tips, with two free ends (72a, 72b) having bent segments. The wireforming system and process holds the commissure tips, or one commissure tip and one bent segmen t, and forms the cusp therebetween. The wire is held by two axially-parallel mandrels (42a, 42b) and cooperating clamps (44a, 44b) which axially rotate a nd move toward one another. A forming surface on each mandrel bends one half of the cusp, the forming surfaces being mirror images of one another. The formi ng surface has a complex curvature specifically designed to shape a particular size of wireform into a desired final three-dimensional shape. After bending all the cusps, the free ends (72a, 72b) of the wire are joined, such as with a tubular crimp (34), and the wireform assembled into a tissue

Title: Sewer inspection chamber with back-flow prevention valve and method and apparatus for installing valve in sewer inspection chamber
Inventor: WATTS LEON B
IPC: E03F7/04
Filed: 1997-04-09
Granted: 2005-12-20
Abstract: An inspection chamber for use in sanitary sewer systems has an integral back-flow prevention valve. The valve can be installed through an access pipe with the inspection chamber in place underground. The valve does not interfere with the installation or removal of a plug in the inspection chamber during construction and inspection of the sewer system. The inspection chamber comprises a clip oriented to receive a valve member from the direction of an access port. The valve member comprises a pin connected to a flap member by a narrow bridge member. The flap member has a projecting handle member. An installation tool holds the valve member by the handle member and provides a tab which can be hammered downwardly to snap the pin into the clip thereby securing the valve member in the inspection chamber. An inspection chamber according to the invention avoids the necessity of providing a separate buried back-flow prevention valve.

Title: Sled board with tracking bottom
Inventor: MEHRMANN CHARLES
IPC: B62B15/00
Filed: 2003-05-02
Granted: 2011-03-15
Abstract: The invention features a soft foam sled board for use by a sitting or kneeling rider to slide over a snow or ice covered surface. The sled is prepared from a shaped polyethylene foam core, and at least the bottom surface of the core is covered by a slick, polyethylene film/polyethylene foam sheet laminate which provides little frictional resistance between the sled board and sliding surface, and provides an impervious outer surface to the board so as to resist puncture and water infiltrate. The sled board has one or more rails, ribs, or fins embedded below the body weight of the rider so as to either protrude from, or jut into, the board. The fins enhance the ability of the sled board to travel down the hill in a straight, forward direction.

Abstract: Bipyridine or phenanthroline ligands presenting functional groups that prevent non-specific binding (in particular, negatively charged functional groups that are unaffected by standard conditions for conjugating biological reagents through amide bonds) are described as are luminescent metal complexes comprising these ligands. The use of luminescent ruthenium and osmium complexes comprising these ligands in electrochemiluminescence assays shows that the use of these labels can significantly reduce the amount of non-specific binding observed relative to assays carried out using reagents labeled with analogous labels that don't present functional groups that decrease non-specific binding.

Abstract: A FEC apparatus and method for reducing Bit error rates and Frame Error Rate s using turbo decoding in a communication system. In a constituent decoder for decoding a turbo code, a first adder calculates the LLR of a received code symbol by calculating the difference between the probability of the symbol being 1 and that of the symbol being 0 at an arbitrary state of a turbo decoding trellis. A second adder adds the transmission information and priority information of the code symbol. A third adder calculates the difference between the outputs of the first and second adders as extrinsic information. A first multiplier multiplies the output of the third adder. A correction value calculator calculates a correction value using the differen ce between the best metric and the second best metric of the code symbol. A fourth adder adds the correction value to the output of the first multiplier .
