Abstract: One embodiment provides a method implemented by a powered inflation device to prepare a balloon catheter for use during a medical procedure. In this embodiment, the method includes drawing an amount of medical fluid from a fluid reservoir into the inflation device during a first motorized operation of the inflation device, removing an amount of air from the balloon catheter during a second motorized operation of the inflation device, and injecting the amount of medical fluid from the inflation device into the balloon catheter during a third motorized operation of the inflation device to inflate a balloon located at a distal end of the balloon catheter. The powered inflation device may be a stand-alone device in one embodiment. In one embodiment, the powered inflation device is coupled to an angiographic injector system. When it is coupled to an angiographic injector system, the balloon inflation device and the injector system may be controlled by a common control panel, or console, in one embodiment.

Abstract: An inter-machine trunk (IMT) is provisioned between two witches through an ATM network. The IMT includes a number of virtual connections (VCs) and cell slots within each VC for carrying telephone calls. The IMT is established by multiple repetitions of an inter-switch signaling process, each resulting in the creation of one VC. The number of VCs and cell slots for the IMT is selected based on provisioning information from a network operator. The IMT may be either a pre-established IMT (“PIMT”) or an on-demand IMT (“VIMT”). A PIMT is a quasi-permanent connection set up and torn down by an operator to provide some guaranteed data-carrying capacity on the IMT. A VIMT is created automatically upon receipt of a call when no connections are available on the IMT. An IMT can use both a PIMT and a VIMT. When a call request is received at a switch, a call processor determines whether the IMT is to carry the call.

Abstract: The compound 2,3-diphenyl-5-ethyl-pyrazine, useful as a precursor in the synthesis of those compounds of the class of pyrazine, arylpyrazine, diphenylpyrazine, and cycloalkylpyrazine malonates, acetates, acetamides, and acetic acids, useful for their ultraviolet light absorption properties.
