Abstract: A subsurface emitter includes a valve both preventing water from draining from the system and blocking the entry of roots and soil into the emitter body. A nozzle is present at one or both ends of a vertical tube. A piston is held in a normally closed position by a spring in the absence of water pressure, covering at least one port in the nozzle. When sufficient water pressure in provided, the spring is compressed and the nozzle uncovers the port providing a subsurface spray of water. The spray of water is sufficient to clear mineral deposits which otherwise may accumulate and block the port.

Abstract: The present disclosure describes methods and systems for managing resources, for example in connection with call admission control or other communications or transactions in a system. In particular, a plurality of resource pools are established. At least a first or priority resource is associated with a minimum resource amount, while at least a second or normal resource pool is associated with a maximum resource amount. From the system resource pools, allocations are made to each of a plurality of system servers. If a server receives a request for priority resources that cannot be satisfied from the allocation of priority resources made to that server, that server may borrow from an allocation of normal resources. Resources can also be shared between servers. Accordingly, if required resources are not available from an allocation made to a server receiving the request for resources, that server can request resources from another server.

Abstract: A distributed call control system is provided that can allot bandwidth amongst several call controllers. The distributed call control system includes one or more servers that execute two or more instances of call processing servers that administer call control. The call processing servers form a cluster or group. The cluster members negotiate and determine bandwidth allocation amongst the members. If a member requires more bandwidth, the call processing server, of that member, assesses its own needs and requests more bandwidth from other members. The negotiation and requests for bandwidth are accomplished with a set of dynamic and static bandwidth data that regiment the control of the bandwidth.

Abstract: The present invention relates to a gripping device that removably attaches onto a user's wrist to enable the user to grip onto a handle. The gripping device comprises a wrist-wrapping, elongated belt portion having opposite ends, and a gripping structure that extends outward from the plane of the belt portion.

Abstract: The embodiments presented herein provide an automated process for provisioning a user in a communication system. A session manager, which can be a server in the communication system that provides call connection and routing, may receive registration request from communication device (e.g. a cellular telephone, an IP-enabled phone, etc.). The session manager may determine one or more characteristics about the communication device and/or determine a load on one or more other session managers in a cluster of session managers. Based on both the communication device characteristics and/or the loads on the two or more session managers, the session manager can determine a set of session managers, which may include a primary session manager and a secondary session manager, which can manage the user data for the communication device. This session manager set information may then be sent to the communication device and to other session managers in the cluster.

Abstract: Recovery time upon the failure of a link or switching system in an asynchronous data network can be minimized if downstream data switches provide upstream messages indicating to upstream switching system that the downstream traffic arrived in tact and was properly handled. Upon this loss or failure of the upstream status message to an upstream switching system, an upstream switching system can reroute data traffic around a failed link or failed switch with a minimal amount of lost data. The upstream status message is conveyed from a downstream switching system to an upstream switching system via a reverse notification tree data pathway.
