Patent number: 5588745Abstract: Methods and apparatus are set forth for preparing and delivering bone cement formed by combining a powdered polymer component and a liquid monomer component. The powdered polymer component is stored in an evacuated mixing chamber. The liquid monomer component, according to one specific aspect of the invention, is introduced into the mixing chamber by a control mechanism which causes the stored powder to be "substantially wet", i.e., all of the powdered polymer component is wet to at least some degree and is otherwise devoid of powder pockets. The control mechanism, according to a preferred embodiment of the invention, stages the release of the liquid monomer into the vacuum packed powder chamber, under the effect of the vacuum, in a timed sequence using a plurality of monomer distribution channels.Type: GrantFiled: September 2, 1994Date of Patent: December 31, 1996Assignee: HowmedicaInventors: Kazuna Tanaka, Jeffrey Kapec, Allan B.

Patent number: 5545460Abstract: Methods and apparatus are set forth for preparing and delivering bone cement from a powdered polymer component and a liquid monomer component by simultaneously injecting the powdered and liquid components, stored in separate component chambers, into an evacuated mixing chamber under the effect of the vacuum; by uniformly mixing the components in the mixing chamber (to thoroughly wet the powder); and by delivering the cement formed by the polymerization process, as needed in an operative setting, utilizing a single ready to use device. The uniform mix is achieved by simultaneously subjecting the contents of the component chambers to the effects of the mixing chamber's vacuum via separate one way nozzles, interconnecting the component chambers to the mixing chamber, which cause the powder to be broadcast and liquid to be sprayed into the mixing chamber.Type: GrantFiled: June 7, 1995Date of Patent: August 13, 1996Assignee: HowMedica, Inc.Inventors: Kazuna Tanaka, Jeffrey Kapec

Patent number: 5542947Abstract: A slotted patella resection guide and stylus used in the preparation of the human patella to accept a patella prosthesis in total knee arthroplasty. The guide includes jaw members for gripping bone, the jaw members including a plurality of calibrated and marked steps (slots) located at a different fixed predetermined height above the desired resection level. Each slot accepts the stylus which may be at least temporarily secured therein. After determining the amount of bone to resect, the stylus is temporarily secured in the appropriate slot (marked as being calibrated to yield the amount of resection desired); and the guide is then clamped onto the patella at the location indicated by the guide/stylus combination, with the stylus resting on the patella in the area where its thickness was measured to establish the depth of cut. After the guide is clamped in position, a sagittal saw is inserted therein to actually perform the resection.Type: GrantFiled: May 12, 1995Date of Patent: August 6, 1996Assignee: Huwmedica Inc.Inventor: Patrick J.

Patent number: 5513371Abstract: Two new classes of interconnection networks are described. The new classes of interconnection networks are referred to herein as the hierarchical shuffle-exchange (HSE) and hierarchical de Bruijn (HdB) networks. The new HSE and HdB networks are highly regular and scalable and are thus well suited to VSLI implementation. In addition, they can be adjusted to match any set of packaging constraints. These new networks are also efficient in supporting the execution of a wide range of algorithms on computers whose processors are interconnected via one of the networks fabricated in accordance with the teachings of the invention. Such computers, also contemplated by the invention, are referred to herein as HSE and HbB computers. Furthermore, methods for implementing the aforementioned wide range of algorithms, particularly those in the classes of Ascend and Descend algorithms, on the novel HSE and HdB computers, constitute a further aspect of the invention.Type: GrantFiled: January 24, 1995Date of Patent: April 30, 1996Assignee: International Business Machines CorporationInventors: Robert E.

Patent number: 5488727Abstract: Methods and related apparatus, for use in programming language systems, are set forth which support compile-time type checking for overloaded functions in an environment supporting subtypes with multiple inheritance. At both compile and runtime, the invention considers the type of all actual arguments of a function to select a proper function instance to execute. Furthermore, the methods contemplated by the invention identify at compile time the set of function instances which might be invoked due to subtype substitutions for the actual arguments. Since type errors on function invocations or variable assignments are usually indicative of a programming error, program reliability can be improved and faults that would otherwise result in runtime errors can be corrected through the use of the invention prior to program deployment.Type: GrantFiled: September 30, 1991Date of Patent: January 30, 1996Assignee: International Business Machines CorporationInventors: Rakesh Agrawal, Linda G.

Patent number: 5416580Abstract: A method (and corresponding apparatus) for determining the size distribution of small particles within a dispersing medium utilizing a particle analyzer that measures the angle of scattered light, including the step of sequentially irradiating the particles within the dispersing medium with each of a plurality of light sources positioned at different angles. The scattered light developed by sequentially irradiating the particles is focused, utilizing at least one collector lens, onto a detector array associated with each such lens and the angular distribution of scattered light associated with each of the plurality of light sources is sequentially measured utilizing each detector array associated with a given lens. Finally, the measured angular distributions of scattered light associated with the plurality of light sources, is translated into a size distribution for the particle ensemble contained in the dispersing medium, using well known inversion techniques, such as deconvolution.Type: GrantFiled: July 7, 1993Date of Patent: May 16, 1995Assignee: General Signal CorporationInventor: Michael N.

Patent number: 5414284Abstract: Methods, apparatus and chip fabrication techniques are described which provide electrostatic discharge (ESD) protection to ion-sensitive field effect transistor (ISFET) based devices used to selectively measure ions in a liquid. According to one aspect of the invention, an ESD protection circuit, made up of conventional protective elements, is integrated onto the same silicon chip on which the ISFET is formed, along with an interface that is in contact with the liquid being measured and which does not open up paths for D.C. leakage currents between the ISFET and the liquid. According to a preferred embodiment of the invention, a capacitor structure is used as the interface between the protection circuit and the liquid sample. Further aspects of the invention are directed to methods per se for providing ESD protection for ISFET sensors utilizing the interface means (e.g, capacitor structure) referred to hereinabove, and processes for fabricating the novel interface on a silicon wafer.Type: GrantFiled: January 19, 1994Date of Patent: May 9, 1995Inventors: Ronald D.
