A face seal includes a seal seat 24 and a seal element 52 carried by a seal housing 32. The seal element cooperates with the seal seat to establish a seal. The housing includes a support 44 for the seal element and a shroud 42 for effecting a gradual transition between a normal condition and a deteriorated condition. The shroud 42 may have a tip 74 whose properties differ in lubricity, hardness or abradability relative to other portions of the seal housing.

A walking stabilizer equipped to combat the effects of akinesia paradoxica by employing a novel method and device to regulate and actuate a projection instrument which generates a pattern perpendicular to the user's direction of travel. The regulating and actuating device comprises a two pole series switch circuit configuration in tandem with the walking stabilizer's novel dual action braking mechanism. The projection device is only operable when the user concurrently selects its use and when the walker stabilizer is free for movement or in contact with the patient.

The present invention provides a method and system for identifying, designing, and synthesizing proteins and protein backbones. The invention permits the qualitative identification of designable protein configurations and synthesis of protein folds. The method and system involve generating backbone protein configurations using a set of dihedral angle pairs, normalizing the total surface exposure of the configurations; generating a random set of sequences of hydrophobicities with uniform weight on the space of allowed sequences; determining, for each randomly generated sequence, which of the remaining configurations is the ground state; recording a ground-state configuration for each sequence wherein the desirable configurations are those containing the most sequences with that configuration as their ground state and finally, synthesizing sequences of amino acids for the desirable configurations.

A detection system may include a moveable tray configured to hold a multi-cell container of one or more reagents and/or one or more samples. A driving mechanism may be configured to reciprocate the tray in the first linear direction to agitate contents of the container, and may be configured to conduct electrochemiluminescence or other measurements on samples located in the container. The system may include an apparatus for retaining a container, a device for detecting the presence of a container, an apparatus for training a probe to locate and aspirate one or more reagents and/or one or more samples, a latching mechanism for moving parts in the system, and/or a positive displacement pump. A controller may be configured to control linear reciprocation of the tray to have one of a piecewise constant velocity profile and piecewise constant acceleration profile in which the number of piecewise constants does not exceed 24.

The present invention relates generally to automatic insurance verification, and more specifically, to a non-invasive method and system for automatically determining, by any person with computer, wireless, or telephone access and in real-time, if an insured object of value is or is not insured irrespective of insurer location, jurisdiction, language, type, time, and also the internal operations, software platform and communications protocols used by insurers and/or governmental entities. It is an insurance verification, not an insurance reporting or tracking system and because it maintains no personal data of any kind, and can modify no record, it can deliver only very limited features regarding reporting or tracking. The present invention can however, provide absolute assurance of current insurance status at all times, provides a unique method of access which resolves all current failures and is non-invasive, providing complete privacy for all parties involved, (the absence of all personal information and the access method used ensures that all access and data is inherently non-invasive). This invention further ensures that any check of status, at insurer or governmental registration, (including “e-registration”, inspection, or any other location and time when and where a jurisdiction or insurer requires such a status check, will result in an instant and totally accurate status response. This system is based upon the assignment of a unique identifier, also known in this present art as a “UC” or “Unique Code” which then provides a method of accurate data, (including status checks), without reliance on “VINs”, (vehicle identification numbers), policy number or other identifiers which are often incorrect. The UC is assigned to any combination of two or more elements that are “gleaned”, (file field extraction and related system and methods), one of which is always current status. The extraction of these selected fields from data streams may be done by a number of prior art techniques, and the three most common have been detailed. First demonstrated to government officials in 1999 as a medical version and later the same year as a vehicle version, it has been demonstrated and documented since to a great many Federal and State governmental entities. This present invention has also been demonstrated to several foreign governments but incorporates no technologies that create any possible security risk for any government, insurer, individual, and especially to the national security of the United States.

The present invention is directed to an isolated peptide that functionally mimics a binding site for a monoclonal antibody, the monoclonal antibody recognizing an epitope within the human platelet glycoprotein Ib/IX complex. This peptide is called a mimotope. The invention also provides an isolated molecule capable of binding to the peptide, or the mimotope, which molecule can be an antibody, a second peptide, a carbohydrate, a DNA molecule, an RNA molecule, or other naturally or chemically synthesized molecules. This isolated molecule is called an anti-mimotope. Mimotopes mimicking the binding site for monoclonal antibody C-34 and SZ-2, as well as anti-mimotopes to the C-34 mimotopes, are specifically provided.

A nozzle assembly for a vacuum cleaner is provided with floor engaging wheels that are frictionally engaged with and rotate additional wheels that are secured to the ends of a brush in a manner such that rotation of the additional wheels causes the brush to rotate. As the vacuum nozzle assembly is moved back and forth across a floor that requires cleaning, the wheels engaging the floor are caused to rotate thereby rotating the brush in the opposite direction. The latter agitates the carpet or other floor covering to loosen and direct dirt particles toward the inlet slot of the vacuum cleaner nozzle.

A by-pass type wet/dry vacuum is provided with a removable lid assembly that includes an electric motor having a lower insulating housing, a cover for the upper end of the motor, a blower housing including vanes for regulating flow of main blower air, a fan having a pancake type impeller, a fan cover and a tank lid having an integrally formed float cage. Assembly of these elements is achieved by making all electrical connections between the motor, a power cord extending to the motor cover, and a manually operated control switch mounted on the motor cover; inverting the motor cover, inserting the upper end of the motor downward into the cover where the former is grasped by snap type retainers formed integrally with the cover, inverting the blower housing and securing same to the motor cover with a plurality of screws, securing the impeller to the lower end of the motor shaft, inverting the fan cover and securing it to the blower housing utilizing screws, placing the float ball in a depression of the fan cover, inverting the tank lid and securing same to the blower housing by means of screws. All of the above elements are assembled to one another without the necessity of lifting any of the elements once they are secured to the other elements.

A portable vacuum cleaner with a bypass fan arrangement: the main fan draws air into the vacuum cleaner housing axially and discharges it radially from the housing; a plenum chamber receives the air from the housing outlet and redirects the outlet air in a direction away from the housing inlet; the motor for the main fan is cooled by a motor cooling fan drawing air over the motor from the end of the motor housing opposite its inlet end; the main air flow and cooling air flows being separate; the housing is shaped internally to assure the separation of air flows just described.
