Abstract: A detachable handle assembly for a tool, the tool for creating a sub-sternal tunnel in a patient. The handle assembly includes a lock-and-release mechanism by which the tunneling assembly is attached to the handle, the mechanism being operable to detach the handle from the tunneling assembly. The handle assembly also may include a knob that interlocks with the tunneling assembly, the knob being configured for engagement by fingers of an adult hand to apply a force to rotate a boring tip of the tunneling assembly.

Abstract: This disclosure describes various tools and associated methods suitable for gaining access to extravascular spaces. The various tools and associated methods utilize a boring tip that may rotate to aid in safely and effectively crossing diaphragmatic attachments. The boring tip may, in some instances not have any sharp edge. For example, the boring tip may have a dome shape but including at least one surface recessed and offset from a summit of the dome shape. Various mechanisms may be used to control rotation of the boring tip as described herein.

Abstract: A sinker or float that releasably clamps around a line, such as a fishing line, including two members shaped to define a channel for the line when in a closed position. A locking means is provided to releasably lock the two members in the closed position. Each of the members has at least a portion of high or low density material to provide a sinking or floating effect. A jacket may be provided that retains the high or low density material therein. The jacket may also include a hinge portion such that the two members can be hingedly opened and closed.

Abstract: Certain embodiments of the present invention provide systems and method for automatic inference and adaptation of a virtualized computer environment. Certain embodiments of a system include a virtual topology and traffic inference framework tool adapted to monitor traffic for an application on a virtual network to produce a view of network demands for the application. The system also includes a monitoring tool adapted to monitor performance of an underlying physical network associated with the virtual network using traffic for the application. Further, the system includes an adaptation component adapted to automatically adapt the application to the virtual network based on the measured application traffic, the monitored network performance, and one or more adaptation control algorithms.

Abstract: In a semiconductor p-i-n photodiode an undoped absorption region (10) is epitaxially grown between two highly doped regions (14, 16). In prior art lattice matched InGaAs p-i-n photodiodes current epitaxial structures use low InP cap (16) doping (n˜2.5−6×1016/cm3), and nominally undoped (not intentionally doped, n˜1×1013−5×1014/cm3) InGaAs absorption regions (10). The shunt resistances of p-i-n photodiodes according to the present invention with intentional doping between n˜5×1017/cm3 and 1×1014/cm3, in the InGaAs absorption region (52, 60) are significantly increased over that of a standard structure (non-intentionally doped).

Abstract: A system for stabilizing a trailer such as a caravan, when parked, or for raising and lowering a pop-top or a television antenna on a caravan, the system having at least one four water actuated ram, and being operable from water supplied from a water tap 47 (faucet) at a camp ground/caravan park. A valve 19 in the supply line 33 prevents loss of water and hence inadvertent actuation/deactuation of the water actuated rams. A selector valve 21 allows selection between extend and retract operations. In the case of a system for stabilizing a trailer such as a caravan when parked, or for raising and lowering a pop-top on a caravan there are at least two water actuated rams and preferably four water actuated rams 11, 13, 15, 17 connected in parallel.
