Abstract:

A bacterial fluid filter includes a filter element supported by a backing member. The filter element and backing member are sealed, e. g. , with one or more o-ring seals, in a housing to provide a filter assembly capable of filtering fluid under relatively high pressure. In one embodiment, a filter element, backing member, and seal are disposed in a removable and disposable housing that is sized to fit within a filter housing.

Assignee:

NCR Corporation - Dayton OH

International Classification:

G06F 1500

US Classification:

712 16, 713400

Abstract:

A method, apparatus, article of manufacture, and a memory stricture for synchronizing nodes in configuring a massively parallel processing system is disclosed. The method comprises the steps of receiving a registration request from each of the non-coordinator nodes in the coordinator node and, after a registration request has been received from all of the non-coordinator nodes, sending a wakeup message from the coordinator node to each of the non-coordinator nodes to wake the non-coordinator nodes from a sleep state. In another embodiment of the invention, the method comprises the steps of transmitting a registration request from a non-coordinator node to a coordinator node; commanding the non-coordinator node to enter a sleep state; receiving a multicast wakeup message from the coordinator node in the non-coordinator node after a registration request is received from all of the non-coordinator nodes in the coordinator node; and waking the non-coordinator node in response to the wakeup message. The apparatus comprises a means for performing the steps described above, and the article of manufacture comprises a program storage device tangibly embodying computer instructions for performing the above method steps.

International Classification:

G06F 15177

US Classification:

713 1, 700 4, 712 28, 709209, 709224

Abstract:

A method, apparatus, article of manufacture, and a memory structure for selecting a coordinator node to configure a parallel processing system having a plurality of interconnected nodes. The method comprises the steps of: multicasting a best available node list and a best desired node list from each node to each node; receiving the best available node list and the best desired node list from each node in each node; and selecting the coordinator node as the node originating a best available node list that includes every node in the desired node list. If no node is identified as originating a best available node list that includes every node in the desired list, the node originating a best available node list that includes the greatest number of nodes in the desired node list is selected as the coordinator node.

International Classification:

A61M 2509

US Classification:

156294, 156256, 1563031

Abstract:

The present invention is a device for insertion into a human or animal body, in a preferred embodiment a perfusion guidewire capable of delivering perfusion fluids to a vascular site while at the same time exhibiting handling characteristics associated with existing non-perfusion guidewires. Preferred embodiments include a perfusion guidewire which closely matches the dimensions and physical characteristics of standard guidewires. Preferred embodiments also permit high pressure perfusion of oxygen-supersaturated solutions, and include a diffuser segment which divides the flow and reduces fluid velocity, thereby providing an atraumatic, non-cavitating, bubble-free delivery to the patient. The invention also encompasses the attachment of a core wire within a tubular housing to provide superior characteristics to such guidewires, balloon catheters and similar devices.

Abstract:

A method for executing database transactions is disclosed. A plurality of interconnected nodes are each defined in terms of processor and storage resources of a parallel computing system. A first set of virtual processors is mapped across a first subset of the nodes to create a first map with at least one virtual processor being mapped to each node in the first subset. A second set of virtual processors is mapped across a second subset of the nodes to create a second map with at least one virtual processor being mapped to each node in the second subset. The first map is stored as a first configuration and the second map is stored as a second configuration. At least one transaction is executed using the first set of virtual processors and simultaneously at least one transaction is executed using the second set of virtual processors.
