Abstract: A pool or spa system includes networked pool or spa devices that can be dynamically configured with network addresses by a controller. The controller can transmit a device discovery request on a network and can receive a discovery response from pool or spa devices that require a network address. The system determines and assigns the network addresses for the pool or spa devices based on unique device identifiers associated with the responding pool or spa devices. The network addresses assigned to the pool or spa device are transmitted to the pool or spa device to be used by the pool or spa devices to communicate with the controller over the network. The system can be used to discover and assign addresses to various types of pool or spa devices, such as pumps, underwater lights, chlorinators, water feature controllers, remote controllers, and/or other types of devices.

Abstract: A valve includes a one piece, Y-shaped body including a main member, a first branch having a first branch flow passage and a second branch having a second branch flow passage. The first and second branches extend outwardly from the main member. A single ball is rotatably disposed within the body. The ball includes a common flow port alignable with the first flow passage in a first rotated position and with the second flow passage in a second rotated position. A ball first flow port open to the common flow port is alignable with the main member in the first rotated position. A ball second flow port open to the common flow port is alignable with the main member in the second rotated position. First and second branch longitudinal centerlines define an included angle less than 90 degrees.

Abstract: A system and method for processing telephone calls and providing enhanced services is presented. The call processing system includes a network control processor for controlling the processing and routing of the calls and for providing enhanced features, and a matrix switch for routing calls from an originating location to a terminating location. Operator consoles can be included to provide operator assistance to the caller. The network control processor comprises a central message processor that receives call data, determines the type of call, determines the processing required, and determines whether operator assistance is required. A call route distributor allocates an operator console to the call if required. A billing server is used to track billing information for the call while it is in progress. A database server is provided for database look-ups and storage.

Abstract: The present invention provides a novel gene encoding DNA sequence for the expression of parathion hydrolase and an analog thereof, and methods for preparing such compounds. In a particularly preferred embodiment, the present invention relates to a parathion hydrolase gene encoding sequence in which twenty-eight amino acids are deleted from the N-terminal amino acid sequence of parathion hydrolase. The novel gene encoding parathion hydrolase encoding sequence is useful for production of the mature or processed parathion hydrolase and a methionine (-1) analog thereof.
