Abstract: A system and method for providing message-based leasing of resources in a distributed computing environment. Services may issue leases to clients and provide operations on those leases. The lease functionality of a service may be defined in an XML message schema. Gates may be used to perform lease operations. Leases may be granted for a period that may be negotiated. Leasing messages for performing leasing operations may be defined. The leasing messages may include messages to renew a lease and to cancel a lease. Services may specify an address where leasing messages may be sent. A lease renewal mechanism may be provided in which a gate may receive lease renewal messages and automatically respond to them. A mechanism to detect stale advertisements in a space may be provided. When a service publishes its advertisement in a space, the service obtains a lease on the publishing of its advertisement. Each advertisement may include a time by which the service may renew the advertisement.

Abstract: A method for transmitting environmental conditions information, which includes receiving at least some environmental conditions information, scaling the received information such that a scaled environmental conditions value is determined for a particular vehicle, receiving an environmental conditions threshold value, comparing the scaled value to the received threshold value, determining whether the scaled value is greater than the received threshold value, and transmitting, if the scaled value is greater than the received threshold value, at least some of the information.

Abstract: A method for fast protection in a fault-tolerant network includes coupling an edge switch in a network to one or more access switches via at least first and second redundant links, respectively connected to first and second ports of the edge switch. The first port is placed in an active state, while the second port is placed in a blocking state, so that communication traffic is conveyed over the first link, and each of the switches builds a respective database for use in forwarding the traffic. Responsive to a failure associated with the first link, the second port is placed in the active state and the first port is placed in the blocking state. Dummy traffic is then sent from the edge switch over the second link to the one or more access switches, so as to cause each of the one or more access switches to modify its respective database responsive to the second port being in the active state.

Abstract: A method and a device for controlling a vehicle in which the vehicle's speed is only regulated, i.e., limited, if descent is detected.

Abstract: The present invention provides a method and apparatus for improving the utilization of a resource in a shared client computer environment. The invention overcomes the problem inherent in using traditional computer programs on a shared client, by monitoring the status of an application, determining when an application does not need a resource, and causing the application to stop consuming the resource. In one embodiment, resource consumption is not halted, but the application is caused to use less of the resource. The invention detects when a user has stopped interaction with an application. This can occur, for instance, when the user removes an identifier from the end user terminal. When the user interaction stops, the invention has a mechanism to stop a program from consuming resources (or to reduce its resource usage) and to restart it (or return it to its original state) later.

Abstract: A surveillance monitoring and automated reporting method is used for detecting observable changes in data sources over a network, such as the internet, for accessing changing data, such as world wide web content data, and for providing scheduled change detection notifications and results through user defined search criteria for automated monitored search criteria matches on a recurring basis by user defined scheduling. The method extracts content data from the data sources and updates a master database, then detects changes in the content data within the search criteria. Upon detection, the user is notified using graphical interfaces, electronic mail messages, pager messages, or personal data assistant messages.

Abstract: A device for Connection Admission Control for an ATM switch, intended for admitting to the switch a requested ATM connection of the DBR type, such that the “Quality of Service” of all ATM connections of the DBR type in said switch continues to satisfy certain conditions. For the composite traffic stream of DBR connections at an output port with capacity C, a single buffer with capacity B is available, while as boundary condition it holds that the total average load of the output port does not amount to more than ?×C, where ? is a constant with a value between 0 and 1. The CAC device comprises two sub-devices, which each execute a—rather complex—partial calculation, resulting in a positive or negative admission signal. The new ATM connection is only granted admission to the switch if both sub-devices emit a positive admission signal.

Abstract: A method for temporarily deleting a stream object, a method for restoring stream objects divided by temporary deletion to the original stream object, and an information structure for the methods, and a recording medium storing information for fast permanent deletion of temporarily deleted parts is disclosed. The methods can solved the problem that full restoration cannot be guaranteed in managing and editing (temporarily deleting) a content, which includes a film, music, or other data, using a plurality of units, and fast response is enabled even when a temporarily deleted part is permanently deleted. Also, a method for generating search information when dividing stream objects through temporary deletion/permanent deletion, which has not been disclosed. Using the information structure and restoration method, stream objects divided by temporary deletion are fully restored to their original state before temporary deletion, and temporarily deleted parts can be permanently deleted quickly.

Abstract: Systems and methods for directing client requests and for selecting a back end server to service client requests. A front end server receives client requests and based on the URI of the requests, directs the request to a back end server. The client request can be for a private or a public folder and each back end server typically stores both private and public folders. If the request is for a private folder, then the front end server determines which server stores that user's private folder and directs the client request to that folder. If the request is for a home public folder, the front end server directs the client request to the server that is associated with the private folders of the users. If the request is for an application public folder, then the front end server selects one of the back end servers to service the client request. Advantageously, the front end server always directs the client request to the same server.

Abstract: A method of selecting a server in a mobile communication system includes registering kinds of resources quantitatively measurable of each server, receiving changed amounts of the kinds of sources at predetermined intervals from each of the servers, receiving a service request with a QoS (quality of service) level from a service user, mapping the QoS level into amounts of the kinds of resources, and selecting at least one server among the servers for the service request based on the changed amounts and the amounts mapped from the QoS level.

Abstract: A navigation device is configured to provide a suitable route that appropriately guides a vehicle to a user outside the vehicle even when the user has moved. The navigation device detects a current vehicle position using a GPS signal receiving section that temporarily stores the vehicle position. The navigation device is configured to receive a signal containing position information from a portable telephone terminal. Then, the navigation device sets the stored position of the portable telephone terminal as the current destination, and calculates a recommended route to the destination. The navigation device communicates with the portable communication terminal to acquire updated position information. Then, the navigation device updates the destination based on the updated position information, and recalculates the recommended route from the current position to the updated destination.

Abstract: A turbine overspeed control system for a gas turbine electrical powerplant. The powerplant may employ an aeroderivative gas turbine engine for producing electrical power. The overspeed control system preferably comprises a compression relief system and an air directing system. When an overspeed condition of the gas turbine engine is detected, the compression relief system acts to remove air from a combustion section of the engine. Preferably, the air is removed to the atmosphere. The air directing system operates to ensure that air entering a compressor section of the gas turbine engine does not impinge on the blades of a compressor turbine located therein at the optimum angle. The result of operating the compression relief and air directing systems is a reduced combustor efficiency. Consequently, a reduced amount of hot gases are available to drive the turbines of the gas turbine engine, and the rotational speed thereof decreases.
