Abstract: A dynamic transfer syntax efficiently transfers data, including large data images, from a server to at least one client. Source data is transformed into a hierarchical representation. The hierarchical representation, consisting of essentially non-redundant data, is a plurality of levels of transform data, such that a level of the hierarchical representation comprises transform data sufficient to reconstruct the source data at a resolution corresponding to the level. The server transfers transform data from a level of the hierarchical representation corresponding to a desired resolution. To render a new view of the source image at the client, the client requests from the server coefficients of the transform data necessary to reconstruct the new view. In response to the request, the server transfers to the client the additional transform data, and the client reconstructs the new view from the coefficients transferred. A medical imaging application for the dynamic transfer syntax is disclosed.

Abstract: A skin puncture device for use as an intravenous catheter or blood collecting needle set is provided with a mechanism for protection against needle injury and access to fluid passageway during insertion. The assembly includes a flexible extension tube connected to the proximal end of the needle housing for use in difficult insertion sites. The extension tube provides access for fluid injection so that the passageway and needle can be filled with fluid prior to needle/catheter insertion, allowing diffusion of blood to provide evidence of successful venipuncture and allowing the infusion of small amounts of fluid into the vein to facilitate catheter advancement. The locking mechanism consists of two apertures in the needle housing and two pairs of needle guard locking tabs which selectively engage when the needle guard is pushed forward to its fully extended position upon completion of insertion or blood drawing, encapsulating the length of the needle.

Abstract: The present invention includes apparatus and methods for disk dampers with an inlet edge and/or an outlet edge, oriented and shaped to control airflow within the hard disk drive. The inlet edge and the outlet edge reduce the airflow turbulence at the actuator assembly. This improves the Position Error Signal (PES), as the read-write head accesses a rotating disk surface. The outlet edge may preferably be curved and oriented at an oblique angle with respect to the angular rotation of the disk(s) in the hard disk drive. The outlet edge may preferably extend over a section of a sector angle. The inlet edge may preferably be oblique, which helps to slow down the overall velocity of the airflow into the disk damper. This allows the tip of the inlet edge to be positioned closer to the actuator assembly than previously possible.
