摘要： A method facilitates providing appropriate quality of service guarantees to a plurality of virtual hosts on a single physical host computer. A server application program and its child processes service communication requests made to the plurality of virtual hosts. Quality of service parameters associated with the virtual hosts are stored. Communication requests made to a specific one of the virtual hosts are detected. The quality of service parameters associated with the specific virtual host are obtained. Operating system resources are utilized to guarantee, to a child process of the server application program, a quality of service according to the obtained quality of service parameters associated with the virtual host. Communication between the virtual host and the client is allowed to proceed, the communication being managed by the child process.

摘要： A novel method and system is disclosed for using a commodity RFID system for automatically measuring levels of soil moisture in planting containers. A large number of planting containers are used to grow pots in soil in a greenhouse. An RFID reader interrogates passive RFID tags affixed to the planting containers. The RFID reader can be attached to a robotic arm configured to move above multiple rows and columns of containers. Signal features of specific passive RFID tags affixed to specific ones of the containers are automatically monitored, including a minimum response threshold of RFID reader transmission power to activate the passive RFID tag (“MRT”), based on the wireless interrogation of specific tags by the reader. Soil moisture levels of specific containers are then automatically determined based on the signal features of the attached tags, and effects of soilure moisture on electromagnetic fields of antennas of tags.

摘要： Activity levels are controlled and transmission costs are reduced for wireless mobile devices. Power consumption is optimized. Mobile device based activities are categorized according to importance, and associated with power thresholds. Actions are specified to perform responsive to the level of the battery dropping below specific power thresholds. The battery is periodically polled to determine its current level. Responsive to the current level dropping below a given power threshold, the associated action(s) are performed. Communication activity is also optimized in compliance with a service plan. A current service plan copy is maintained on the mobile device. Actions are specified to take when communication reaches given usage thresholds within a plan period. Communication use is tracked, and compared with usage thresholds. Responsive to communication reaching a threshold within a plan period, the associated action(s) are performed.

摘要： A data transmission system and method employing either a renegotiated variable bit-rate ("RVBR") network or a renegotiated constant bit-rate ("RCBR") network. Within these networks, data transmission rates between a sender and a recipient are rapidly renegotiated as a function of previously stored data transmission rate information and system buffer levels. Such a system and method can be readily implemented within existing CBR and/or VBR network architectures. The RCBR and RVBR networks allow for the implementation of an intelligent data traffic management systems that are responsive to the rate at which new calls or requests for connections enter and leave the network, the frequency and duration of extended peak rate data bursts, as well as the occurrence of short duration data transmission peaks.

摘要： Resource requests from a plurality of schedulable entities are scheduled while limiting the maximum and minimum quality of service allocated to each schedulable entity. The resource scheduler of the present invention requires less memory maintain state information than existing rate-controlling schedulers, and is thus more easily scalable to large numbers of users. The resource scheduler also schedules resources fairly among competing schedulable entities. A fair-share scheduling algorithm is used by a resource scheduler to select resource requests to service. A rate controller checks to ensure that servicing the selected request will not cause the associated user's maximum quality of service to be exceeded. If the maximum quality of service will not be exceeded, the virtual time used in the scheduling algorithm is incremented, and the request is serviced. If the maximum quality of service will be exceeded, the virtual time is still incremented, but the request is not serviced and remains pending.
摘要翻译：调度来自多个可调度实体的资源请求，同时限制分配给每个可调度实体的最大和最小服务质量。本发明的资源调度器比现有的速率控制调度器需要更少的存储器维护状态信息，因此更容易地扩展到大量的用户。资源调度器还可以在竞争的可调度实体之间公平地调度资源。资源调度程序使用公平共享调度算法来选择资源请求进行服务。速率控制器检查以确保为所选择的请求提供服务不会导致超出相关用户的最大服务质量。如果不超过最大服务质量，则调度算法中使用的虚拟时间增加，并且请求得到服务。如果最大服务质量将被超过，则虚拟时间仍然增加，但请求未被维护并保持挂起。

摘要： A method and system for handling incoming calls when no destination stations are available. When an incoming call from an originating station is received, it is determined whether a destination station is available. If a destination station is not available, a telephone number of the originating station is stored, Shortly before its current call is concluded, a destination station indicates its approaching availability. Responsive to this indication, an outgoing call is placed to the originating station. If the originating station does not answer the outgoing call within a predetermined time, the outgoing call is terminated and rescheduled. If the originating station answers the call within a predetermined time, the outgoing call is connected to the available destination station.

摘要： Methods are provided for achieving consensus among an order in which write requests are received by various ones of a plurality of nodes in a distributed system using a shared data structure. The plurality of nodes are organized into groups of nodes and successively larger groupings of groups, based on physical proximity. A consensus protocol is used to achieve consensus among groups of nodes, and then among the groupings of groups of nodes in a logical tree structure up to a root level virtual node. Recovery from failure of all nodes in a group is supported.

摘要： The short-range wireless communication on a mobile communication device is optimized to balance between preserving battery power and processing urgent data without delay. A wireless access schedule identifying time periods during which the mobile communication device is assumed to have access to short-range wireless communication is created or provided. Data to be transmitted or received by the mobile communication device is classified as being urgent or non-urgent. When data is to be transmitted or received by the mobile communication device, the transmission or receipt of the data is managed according to 1) whether or not the data is urgent, and 2) whether the current time is within a time period during which the mobile communication device is assumed to have access to short-range wireless communication.
