Title: High bandwidth packet switch
Inventor: MCHARG CHRISTOPHER GORDON
IPC: H04L12/56
Filed: 1993-05-25
Granted: 1999-11-02
Abstract: A fast packet switch comprising one buffer directly connected between a plurality of input ports and a plurality of output ports to effect rapid throughput of data packets. A pointer to a location in the buffer is allocated by a buffer manager upon receipt of notification of an incoming packet at the receiving input port and the input port delivers the packet as it is received to the location designated by the pointer. After the data packet is received, the input port delivers the pointer and a destination address for the packet to a router, which selects one of the plurality of output ports based on the destination address. The router queues the pointer in a queue for the selected output port. The output port then retrieves the data packet from the buffer using the pointer to determine the location, and transmits the data packet. After the transmission is complete, the output port returns the pointer to the buffer manager. This packet switch may be pipelined to receive, route, and transmit simultaneously on adjacent data packets.

Title: Safety penetrating instrument
Inventor: YOON INBAE
IPC: A61B10/02
Filed: 1991-12-18
Granted: 1999-01-26
Abstract: The safety penetrating instrument (30) includes a tubular needle (32) having a d istal end with a sharp tip (46), a safety probe (34) movable within the needle between an extended position protecting the needle tip and a retracted position exposing the needle tip and is biased toward the extended position and a portal sleeve su rrounding the needle to establish communication with an anatomical cavity with penetration of tissue surrounding the cavity by t he needle. The needle distal end has a leading edge defining the sharp tip and a trailing edge and the portal sleeve has a dist al edge disposed in substantial alignment with or forward of the trailing edge of the needle distal end. A locking mechanism autom atically locks the safety probe in the extended position after the safety probe is returned thereto or can optionally allow lock ing of the safety probe or allow proximal movement of the safety probe after return to the extended position. The locking mechanism also provides selective locking of the safety probe in the retracted position.
Patent CA-2100541-C (CA)
Title: Distributed processing of route selection across networks and subnetworks
Inventor: DOERINGER WILLIBALD A
IPC: H04L12/56
Filed: 1993-07-14
Granted: 1999-05-25
Abstract: The process  for determining the best communication route from a source end station to a destination end station is distributed over both source and destination network nodes. Network nodes, at the interface between a wide area network (WAN) and each subnetwork, contain access agents to control the communication flow between the wide area network and an end station in the subnetwork.  The task of selecting the best route between two end stations is distributed between the  access  agents  at  the  WAN  interface  in  the  first subnetwork,  and the access agents at the WAN interface in the  second  subnetwork.   Each  access  agent  at  one  WAN interface obtains the best route from itself to the end station in its subnetwork.  Each access agent at the other WAN interface finds the best route from each access agent at the first WAN interface through itself to the end station in its subnetwork.   One designated access agent collects all the best route information.  This best route information is concatenated,  and  the  route  with  the  least  weight  is selected as the best route between end stations.

Title: Concentration of solids in a suspension using hollow fibre membranes
Inventor: KOPP VIRGIL CLINTON
IPC: B01D61/14
Filed: 1992-08-07
Granted: 2002-07-02
Abstract: A microporous filter assembly is disclosed which, in some modes of operation, has feed pressure fed to the external walls of the microporous fibres (13) comprising the filter. In other forms feed is caused to move across the walls of the fibres (13) by the application of a lowered pressure to the lumens of the fibres (13). Various forms of backwashing of the fibres (13) are disclosed, with none of the modes requiring a prepressurisation step of the environment within and around the fibres (13) prior to com-mencement of backwash. In particular forms of backwash, initial steps of the backwash include terminating supply of feed to the exterior surface of the fibres (13) and substantially removing remaining filtrate from the lumens of the fibres (13). In some em-bodiments the filter comprises a filter cartridge (10) including a bundle of fibres (13) housed within a closed, pressurisable shell (12). In other embodiments the filter comprises one or more bundles of fibres (102) suspended within an open vessel (101). The invention reduces the number of required pressurisation cycles of the environment within and around the fibres (13). In some forms such pressurisation is eliminated.

Title: Femoral milling instrumentation for use in total knee arthroplasty with optional cutting guide attachment
Inventor: BERTIN KIM C
IPC: A61B17/17
Filed: 1994-06-23
Granted: 2005-01-25
Abstract: The milling instrumentation of this invention provides a milling guide connected to the femur for accommodating a milling device. The milling instrumentation includes an alignment guide which is used by the surgeon to set a femoral bracket or base on the medial and lateral sides of the exposed femur adjacent its distal end. Once the brackets are set, the alignment guide is removed and a milling guide is connected to the bases. The milling guide establishes a series of reference planes each including a slot. A powered milling device having a burr connected thereto is guided by the slots along the reference planes to accurately mill away a portion of the bone. The milling device includes a bobbin-shaped tip which positively engages the slots to ensure that the milling device is held substantially perpendicular to the reference planes of the milling guide. If necessary, other instrumentation may be connected to the femoral bases which would form a common connection point for the additional instruments thereby ensuring alignment between the various instruments. Optionally, a one piece cutting guide may be connected to the bases to allow resection of the bone by a standard oscillating saw blade. The cutting guide includes a plurality of slots such that all the cuts required for the femur can be made with one cutting guide without reorienting the guide.

Abstract: The present invention provides a method and apparatus for message packet authentication to prevent the forging of message packets. A portion of the message digest, referred to as the signature, is then appended to the actual message when it is sent over the wire (205). The receiving station strips the signature from themessage (208),preappends the same secret session key (209) and creates its own message digest(212). The signature of the digest created by the receiving station is compared to the signature of the digest appended by the sending station (213). If there is a match, an authentic message is assumed (214). If there is no match, the message is considered as invalid and discarded (216).
