Abstract: A centralizing bushing assembly includes a bushing housing having axial ends and an opening extending therethrough along an axial axis. The opening can have a pocket extending outwardly from the axial axis within the bushing housing and have internal shoulders axially facing each other. A bushing ring can be positioned within the pocket of the bushing housing between the internal shoulders. The bushing ring can have a split for allowing collapsing of the bushing ring radially inward and have an inner diameter for slidably engaging an axially movable shaft extending through the bushing housing along the axial axis and also have an outer shoulder. A resilient biasing member can be positioned against the outer shoulder of the bushing ring for radially biasing the inner diameter of the bushing ring radially inwardly in a centralizing manner about the axial axis for engaging and centralizing the shaft slidably positioned therethrough.

Abstract: A method, system and apparatus for managing an interposed reverse proxy. The method can include comparing within a markup language document, a host address for the markup language document and a codebase address for a code base supporting logic disposed within the markup language document. If the host address and the codebase address differ, it can be concluded that a reverse proxy has obscured from view a server source of the markup language document. The method of the invention further can include retrieving a server affinity identifier for the server source from the configuration tags for the logic. Responsive to concluding that a reverse proxy has obscured from view a server source of the markup language document, a tunneled connection to the server source can be attempted through the reverse proxy by inserting the server affinity identifier in an address specified in the attempt.

Abstract: A method, system and apparatus for tunneling non-hypertext transfer protocol (HTTP) data streams through a reverse proxy. The method can include soliciting a connection with a reverse proxy protecting a back-end server computing device. A connection can be established with the back-end server computing device via the reverse proxy through the solicitation. Responsive to establishing the connection, the connection can be maintained in order to exchange non-HTTP data over the secured connection. Significantly, and unlike prior art HTTP tunneling implementations, in the present invention, the non-HTTP data can be exchanged over the connection without encapsulating the non-HTTP data within HTTP messages.

Abstract: A head stabilizer for a patient support backboard comprising a pair of slotted retainers extending laterally across the top of the backboard, and a pair of hinged head restraint units with projections for reception in the retainer slots to selectively position these units apart from each other laterally of the backboard. The head restraint units are removable for cleaning and may be folded up for storage on the backboard between the retainers.
