A method of performing an arthroplasty of a ball and socket joint with a surgical navigation system includes the step of digitizing landmarks to provide geometrical parameters of the joint and a limb depending there from, including digitizing aspects of a socket region of the ball and socket joint. A range of motion parameter is determined. A soft tissue tension parameter is determined. A functional goal is computed based on landmark data, the range of motion parameter, the soft tissue tension parameter, and a database of potential implants. An optimal socket position is solved for to minimize impingement of potential implants. An implant is chosen based on the optimal socket position and the functional goal. The joint is prepared to receive the chosen implant. The chosen implant is installed into the joint.

A method is provided for the application of a finishing layer to a textile support material. A water repellent or oil repellent layer, a so-called finishing layer, is applied to a textile support material selected from the group of fibers, tissues, and fabrics. The water repellent or oil repellent finishing layer comprises at least two water repellent or oil repellent components wherein a first component comprises one or more dispersants and a second component comprises one or more dispersed phases or colloids, and wherein the dispersant and the dispersed phase are present in the gel state.

The present invention is a component carrier (132) consisting of a plate of insulating material having a plurality of apertures (140) for accepting the leads of a thru-hole differential and common mode filter (130). Another embodiment consists of a surface mount component carrier (10) comprising a disk (16) of insulating material having a plurality of apertures (24). The same concept for the above described carrier is also incorporated into several alternate embodiments, either independently, embedded within electronic connectors. The overall configuration and electrical characteristics of the concepts underlying the present inventions are also described as an energy conditioning circuit assembly which encompasses the combination of differential and common mode filters and component carriers optimized for such filters. The various embodiments of component carriers provide increased physical support and protection to differential and common mode filters and substantially improve the electrical characteristics of the filters due to the increased shielding provided by the carriers. Embodiments of the carrier energy conditioning assembly include integrated circuit construction for a differential and common mode filter coupled to the power bus of an integrated circuit.

The present invention provides for compositions and methods for preparing aqueous insoluble, ductile, flexible silk fibroin films. The silk films comprise silk fibroin and about 10% to about 50% (w/w) glycerol, and are prepared by entirely aqueous processes. The ductile silk film may be further treated by extracting the glycerol from and re-drying the silk film. Active agents may be embedded in or deposited on the glycerol modified silk film for a variety of medical applications. The films may be into 3-dimentional structures, or placed on support surfaces as labels or coatings. The glycerol modified silk films of the present invention are useful in variety of applications such as tissue engineering, medical devices or implants, drug delivery, and edible pharmaceutical or food labels.

Intraocular lens consisting of a centrally located lens part with supporting parts (haptics) on either side. According to the invention one supporting part is non-deformable and another supporting part, located approximately opposite said supporting part, is deformable. In this way it is achieved that when the ciliary cell contracts the reduction in the space therein is used for moving the centre of the lens part. By arranging the transition between distance and near part in a multifocal lens on said centre, switching from the distance part to the near part can be obtained for the user in an almost natural way.

A means for replacing common sugars (particularly sucrose) in a range of foods that maximizes sugar-like taste, texture and other key properties of sugar while minimizing the undesirable traits such as blood sugar response, digestive side effects, high caloric content and aftertastes. Various differing ratios and combinations of high intensity sweetening agents, high molecular weight bulking agent(s), substantially non-digestible sugar(s), and low molecular weight sugar alcohol(s) are used for various applications such as tabletop sugar substitute, frozen deserts, condiments, baked goods, chocolate and confectionaries have different formulations. These sugar replacement approaches are highly relevant to the production of diabetic-friendly foods, diet and/or reduced calorie foods, non-cariogenic (tooth-friendly) foods and other sweet, low-glycemic foods.

Lubricants, especially lubricating oils, and fuels, especially hydrocarbon fuels, contain a class of anti-wear, anti-fatigue, and extreme pressure additives that are derived from silanes. The additives can be used as either partial or complete replacements for zinc dialkyldithiophosphates currently used in lubricants and fuels.

The invention provides a method for improving functional property of rice protein by protein-polyoses graft coupling technology, which belongs to the technical field of hydrophobicity vegetable protein modification. The method is to carry out glycosylation modification on a side product of producing rice starch and rice syrup, namely the rice protein as a raw material by different glycosyl donors through a wet method. Dissolvability, emulsibility, foamability and other functional properties of the rice protein are effectively improved and sufficiently utilized through the graft reaction of the rice protein and sugar. Compared with methods chemically modifying the vegetable protein, such as alkylation, phosphorylation, deamidization and the like, the method is safe and environment friendly, a rice protein-polyoses graft coupling product can be used as a natural macromolecular emulsifying agent or a protein nutritional reinforcing agent to sufficiently reflect and exert low sensitivity and high nutritive characteristic of the rice protein, thereby effectively expanding the application field of the rice protein. Meanwhile, the method provides theoretical reference for deep research and development of the hydrophobicity vegetable protein.

A roof vent construction which is comprised of an assembly including a cowl, a base, and a cowl retaining member. These elements provide a structure which provides cover for rain and discourages rain from entering the vent underneath the cowl, but nevertheless allows for suitable ventilation as needed. In one embodiment a configuration is used in which an external baffle is used which air passes before passing underneath a cowl. Once the air is passed underneath the cowl, the air then passes over one and one configuration two internal baffles before the air passes out of a pair of vent cavities defined by the base. In a second configuration, a cowl extends substantially to the leading edge of the construction. Air flows underneath the leading edge of the cowl and then passes over a large internal baffle, over a first small internal baffle, and finally over a second small internal baffle before passing through the vent cavities and out of the structure. Another invention relates to the use of two surface portions on the vent assembly, one surface portion configured to match a first course of tiles and the other surface portion configured to match a second course of tiles adjacent to said first course of tiles.
