摘要:
A system for managing access to resources in a plurality of servers by a plurality of client computers by using an operating system independent Secure Shell (SSH) protocol running in each server and using a central policy database that centrally stores access rules which specify access to the servers for a plurality of users/accounts. Each time a target server receives a user request to establish an SSH session, it retrieves associated access rules from the central policy database to obtain the latest access rules. Based on the retrieved rules and the identity of the user and the identity of the client computer, the target server determines whether the user has permission to establish the SSH session with the target server. Using a centralized database and requiring the servers to always retrieve the latest access rules from a central database provides consistent application of the access rules across all servers and all client computers.

A process for increasing the strength of pure copper and other fcc matrix alloys. The method is particularly applicable to face-centered-cubic materials that undergo dynamic recovery when strain-hardened at room temperature. A cryogenic strain hardening process is used to create a high strength pure copper or copper+Al2O3 alloy. The strength of the material is substantially increased. However, the loss of conductivity is minimal. In the preferred embodiment, pure copper or a copper alloy is drawn into a wire at a temperature of about 77 K. Dynamic recovery of the material is substantially reduced. With this method, drawn copper wire exhibits a strength level about 45% higher than that achievable by an equivalent room temperature deformation.

Method and apparatus are disclosed for treating congestive heart failure by administering a fibrosis-inducing agent to an epicardial surface of the heart in an amount selected to induce the formation of fibrosis on the epicardial surface. The fibrosis-inducing agent may be a drug, metal, abrasive or an electrical stimulation on the epicardial surface.

An airbag having an array of slits formed therein between its two attachment points, each slit seamed to be impermeable to the inflation medium. The slits are oriented to be perpendicular to a line defined by these two attachment points. The slits may be in offset rows and are each longer than the distance between the rows to allow the airbag to be significantly expanded by pulling in opposite directions on its attachment points. The airbag thus made can, when expanded, be folded to fit into a housing running along the roofline of a vehicle. Upon inflation and forcing itself from the housing, it will contract sharply, increasing its tension between attachment points and serving to both cushion and restrain passengers against lateral impact.

A resilient rod that provides adjustable directional resistance is disclosed. In one aspect of the invention, a resistance level may be determined based on a thickness of the rod and a position of an applied force with respect to a fulcrum point. In another aspect of the invention, at least one spine may be attached to the beam to increase a diameter of the beam along one axis. A resistance level may be determined based on a thickness of the rod, a position of an applied force and an orientation of the at least one spine with regard to the direction of the applied force. In other aspects of the invention, the resilient rods may be incorporated into various equipment that provide for adjustable resistance levels. In still other aspects of the invention, the resilient rod may be incorporated into medical devices that provide adjustable support for injured limbs or joints.

A repository manager facilitates robust revision control of components of a large scale system. The repository manager stores system components under revision control in a repository, according to internal names. The repository manager also stores binding information between internal names of system components and associated external names, as well as component attribute information. The repository manager provides users with working areas, from which they are able to access system components according to their external names, via the repository manager. As users perform operations affecting system components, the repository manager keeps track of the performed operations. Responsive to a user committing a set of changes, the repository manager updates the master repository according to the performed operations, associates a new version number with the resulting state of the repository and synchronizes the user's working area with the updated repository.

A sports apparatus provides a variable resistance to a user. A resilient panel can be adjusted for custom resistance. The resilient panel is provided with pulleys and cables arranged to deflect the panel when a user provides a force on the cable. The user can transmit force to the resilient panel by attaching a suitable exercise implement to the cable. The resilient can also be arranged as required by the type of exercise and for convenience.

摘要:
A footstand for stabilizing a body of a medical device against being overturned. The body may especially be a chest drainage unit (CDU) designed and configured to receive and collect fluids from a medical patient. The invention comprises at least one stand coupled to the body and adapted for deployment to a position for stabilizing the body against upset. The CDU body is a generally upstanding rectangular box having a pair of depending feet, one foot on each side of the body. The stand, is rotatably connected to the bottom of the CDU body and is provided with a height adjustment feature which allows the stand to be rotated between a first undeployed position wherein the stand covers or encloses the depending fee of the CDU body while providing a relatively smooth and continuous bottom stand surface to a second deployed position wherein the bottom stand surface is at the same height or in the same horizontal plane as the bottom of the depending feet of the CDU body to provide a solid and secure footstand for the CDU body. It is desirable to provide a footstand for a CDU which provides a smooth contoured surface for the CDU bottom when the footstand is in its first undeployed position so that the CDU bottom will not puncture the sterile package during transportation of the CDU to an end user or during storage of the CDU prior to use or during disposal of the CDU after use in a hazardous disposal bag.
