A compressor system includes a first compressor, which has a first low side oil sump, in a first shell and a second compressor, which has a second low side oil sump, in a second shell. The first and second compressors are connected in series. There is an oil transfer conduit connected between the first low side sump of the first compressor and the second low side sump of the second compressor. The system also includes a normally open check valve in the oil transfer conduit. A method for effecting oil balance in a compressor system, the method includes establishing a first compressor in a first shell having a first low side oil sump and establishing a second compressor in a second shell having a second low side oil sump. The first and second compressors are connected in series. The method also includes positioning an oil transfer conduit between the first low side sump and the second low side sump and positioning a normally open check valve in the oil transfer conduit.

A replication process provides fault tolerance for a continuous media stream in a computer network. In one embodiment, the original or source signal is sent to several splitters which, in turn, each make copies of the signal and send the copies into a second layer of devices, which are referred to as “concentrators.” A given concentrator receives as input one or more copies of the source signal. In a preferred embodiment, a given concentrator receives two copies of the source signal from at least two different splitters. The concentrators process the incoming streaming signal copies, for example, by merging them into a single or composite copy of the original source signal according to a given processing algorithm. The output of a given concentrator may then be fed into a splitter, with the process then being repeated if desired to make an arbitrary large number of copies of the signal. At the end of the replication process, the output of a splitter or a concentrator is fed directly or indirectly to an end user. The replication process is fault-tolerant, and thus the end user's signal is not interrupted regardless of signal or equipment problems within the distribution mechanism.

A hinge for use in a motor vehicle, including first and second members pivotably coupled to each other. First and second position retainers are coupled between the first member and the second member to releasably secure the second member in a first holding position relative to the first member. The first position retainer has a first holding portion and the second position retainer has a second holding portion such that one of the first and second position retainers is structured and arranged to move relative to the other of the first and second position retainers such that the first and second holding portions move into and out from a first holding position. The first and second holding portions are structured and arranged to be releasably secured to each other in the first holding position.

A method of treating sleep apnoea and/or snoring in a patient, which includes the steps of providing apparatus for electrically stimulating one or more afferent fibres of a nerve (2), positioning said apparatus (12, 13) on or in close proximity to said nerve; and activating said apparatus to stimulate one or ore afferent fibres of said nerve (2).

A cuff for medical applications, which may be sewn, glued or frictionally fitted in place; the cuff is made of a flexible openwork structure of a medically acceptable metal such as titanium or a titanium alloy; the flexible openwork structure may be e.g. manufactured from wire using a knitting, weaving or chainmail type structure.

A wireless access point in an object location system is provided that includes a tag filtering agent 128 operable to (a) receive tag information from a mobile communication device 104, (b) compare the received tag information with a set of a plurality of tag information to determine whether to report the received tag information to a central registry 116; and (c) when appropriate report the received tag information and physical location information to the central registry 116. The tag information corresponds to tag information contained by a tag 120 on an object and was obtained by a tag reader 256 on the mobile communication device. The physical location information corresponds to a physical location of the mobile communication device 104 at a selected point in time.

A social matchmaking service selects matches of on-line game players based on personal/social characteristics of the players. The social matching service evaluates several criteria to obtain a list of available, socially compatible, game sessions. Criteria about the player include a player's friends, positive feedback about the player, negative feedback about the player, games completed with other players, players to avoid, and the player's gamer zone, country and language. Criteria about hosts of potentially compatible game sessions are also considered. Social matching utilizes a multi-pass approach, applying rules for prioritizing social criteria at each pass. The multi-pass approach starts with a narrow search and broadens the search at each successive pass. At each successive pass, sessions are added to the list of potential sessions until a reasonable number of sessions is achieved. Game sessions are assigned session values in accordance with affiliations between players.

A baton having a stick with a smaller side handle secured at an angle thereto to move with the stick and an axle which passes through a spindle and attaches it to the free end of the side handle. The operator can now grasp the baton by the spindle with his or her index finger and overlying thumb, while the baton's stick and side handle rotate. A top ridge or stop prevents the grasping hand from slipping off the handle laterally. The middle, ring and little fingers and palm of the hand can now be used to firmly grasp the side handle to precisely interrupt the rotary travel of the baton's stick and side handle while the baton remains secured at its spindle by the operator's index finger and thumb. When the side handle is grasped between the operator's middle, ring and little fingers and his or her palm, the handle, fingers and palm act as a drum brake with the handle acting as the brake drum and the skin of the operator's fingers and, primarily, the skin of the operator's palm acting as the brake pad. As the skin is pressed against the side handle more and more forcefully, forces of friction bring the rotating side handle to a stop. Cutting grooves into the rotating side handle, that is attached to the bound spindle, can make this breaking even more precise. The grooves and their corresponding ridges rotate and contact and drag along the surface of the operator's palm skin at different speeds. Different areas on the continuous sheath of highly elastic palm skin simultaneously experience forces of friction of differing magnitudes.

Disclosed are various disease indications and treatment methods that benefit from selective lung region isolation. A lung region is bronchially isolated by regulating the flow of fluid to and from the lung region, such as by implanting one or more bronchial isolation devices into one or more bronchial passageways that feed air to the lung region. The bronchial isolation devices can comprise, for example, one-way valves, two-way valves, occluders or blockers, ligating clips, glues, sealants, and sclerosing agents.

An archive cluster application runs in a distributed manner across a redundant array of independent nodes. Each node preferably runs a complete archive cluster application instance. A given nodes provides a data repository, which stores up to a large amount (e.g., a terabyte) of data, while also acting as a portal that enables access to archive files. Each symmetric node has a set of software processes, e.g., a request manager, a storage manager, a metadata manager, and a policy manager. The request manager manages requests to the node for data (i.e., file data), the storage manager manages data read/write functions from a disk associated with the node, and the metadata manager facilitates metadata transactions and recovery across the distributed database. The policy manager implements one or more policies, which are operations that determine the behavior of an “archive object” within the cluster. The archive cluster application provides object-based storage. Preferably, the application permanently associates metadata and policies with the raw archived data, which together comprise an archive object. Object policies govern the object's behavior in the archive. As a result, the archive manages itself independently of client applications, acting automatically to ensure that all object policies are valid.
