Publication number: 20080256090Abstract: In a network of computer nodes, a directory service provides both the physical location of directory information around the network and the directory information itself in a single data structure. This single data structure is distributed throughout the network, and continuously redistributed, so as to create a directory service that is both more flexible, and more robust, than prior art directory services.Type: ApplicationFiled: June 23, 2008Publication date: October 16, 2008Applicant: MANGOSOFT CORPORATIONInventors: Daniel J. Dietterich, Robert S. Phillips, John B. Carter, Scott H. Davis, Steven J. Frank, William Abraham

Patent number: 7136903Abstract: A multi-user file storage service and system enable each user of a pre-subscribed user group to communicate with a remote file server node via a wide area network and to access the files of the file group via the respective client node. More than one user of the pre-subscribed user group is permitted to access the file group at the remote file server node simultaneously. Integrity of the files at the remote file server node are maintained by controlling each access to each file at the remote file server node so that each access to files at the remote file server is performed, if at all, on a respective portion of each file as most recently updated at the remote file server node. Additionally, an encrypted key is transferred from the file server node to a particular client node via a secure channel. The encrypted key uses an encryption function and a decryption function not known locally at the remote file server.Type: GrantFiled: November 1, 2000Date of Patent: November 14, 2006Assignee: Mangosoft Intellectual Property, Inc.Inventors: Robert S. Phillips, Scott H. Davis, Daniel J. Dietterich, Scott E. Nyman, David Porter

Patent number: 7058696Abstract: A multi-user file storage service and system enables each user of a user group to operate an arbitrary client node at an arbitrary geographic location to communicate with a remote file server node via a wide area network. More than one user of the user group is permitted to access the file group at the remote file server node simultaneously, but the integrity of the files is maintained by controlling access so that each access to one of the files at the remote file server is performed, if at all, on a respective portion of that file as most recently updated at the remote file server node.Type: GrantFiled: November 1, 2000Date of Patent: June 6, 2006Assignee: Mangosoft CorporationInventors: Robert S.

Patent number: 6148377Abstract: Distributed shared memory systems and processes that can connect into each node of a computer network to encapsulate the memory management operations of the connected nodes and to provide thereby an abstraction of a shared virtual memory that can span across each node of the network and that optionally spans across each memory device connected to the computer network. Accordingly, each node on the network having the distributed shared memory system of the invention can access the shared memory.Type: GrantFiled: November 22, 1996Date of Patent: November 14, 2000Assignee: Mangosoft CorporationInventors: John B.

Patent number: 5909540Abstract: A network of computer node interface to globally addressable memory system that provides persistent storage of data exchange periodic connectivity information. The exchanged connectivity information provides information regarding node failure to other nodes in the system, and the surviving nodes use the information to determine which node, if any, has ceased functioning. Various processes are used to recover the portion of the global address space for which the failed node was responsible, including RAM directory, disk directory, or file system information. Additionally, nodes may be subdivided into groups and connectivity information is exchanged between nodes belonging to a group. Each group then exchanges group-wise connectivity information and failures may be recovered.Type: GrantFiled: May 2, 1997Date of Patent: June 1, 1999Assignee: Mangosoft CorporationInventors: John B.

Patent number: 5782615Abstract: A pump assembly (20) includes a rotor (40) and a stator (38) which are disposed within a housing (24) and partially define pumping chambers (56). Fluid is conducted through an inlet passage (104) to an inlet cavity (58) which is connected with the pumping chambers (56). Fluid is conducted from the pumping chambers (56) to an outlet (62) from the pump assembly (20). A tubular passage liner (112) is disposed in the inlet passage (104) and has a straight passage (138) through which fluid flow is conducted to the inlet cavity (58). The tubular passage liner (112) prevents erosion of the housing (24) during conduction through the inlet passage (104) of inlet fluid and fluid bypassed from the outlet (62) of the pump assembly (20). Projections (204 and 206) at one end of the tubular passage liner (112) are engageable with the stator (38) to limit movement of the tubular passage liner relative to the stator.Type: GrantFiled: March 28, 1996Date of Patent: July 21, 1998Assignee: TRW Inc.Inventors: Bruce C.
