Abstract: Chlorinators with multiple spaced gas traps and flow sensors are detailed. The sensors also may be protected, at least somewhat, from contact with scale build ups by interposition of a mechanical barrier. Ramps or other geometric restrictions may be used to increase water flow to some or all of the gas traps. Additionally, the chlorinator housing may be configured so as to route, or focus, gases toward a small-sized, high point thereof.

Abstract: A communications system is provided employing two-way integration approach providing access to notifications and actions occurring on unmanaged communication devices through the use of TV. The system includes installation of an application on unmanaged devices providing the ability to access all notifications and actions occurring on the unmanaged devices using TV. The unmanaged device obtains an input directly from TV from an application server which in turn obtains its input primarily from a TV. The input is not limited to the TV only, and can come from other sources.

Abstract: Systems and methods are provided for automatically addressing devices of pool and spa systems in a communication network. The communication network includes at least a first transceiver and a second transceiver that are communicatively coupled via a communication network bus. The first transceiver is configured to transmit a query signal to the second transceiver on a first address on the communication network bus, where the query signal includes a command requesting identification data (e.g., a serial number) associated with the second transceiver from the second transceiver. After receiving a response from the second transceiver, the first transceiver verifies (e.g., validates) the identification data. The first transceiver then automatically addresses the second transceiver individually by transmitting an addressed signal that includes at least a portion of the verified identification data and a command to the second transceiver on a second address on the communication network bus.

Abstract: Systems and methods of (remotely) controlling aspects of pools and spas and of modifying water contained therein are detailed. Internet-enabled access to pool and spa controllers may happen without any need for users to create firewall ports or utilize static internet protocol addresses. Certain networking devices may be configured using a USB connection or SD card, avoiding any requirement for an Ethernet cable or supplying separate power to the devices during configuration. Time-varying data may be obtained in respect of one or more installations and analyzed for various information.

Abstract: A swimming pool cleaner may operate within a pool during a cleaning cycle. The duration of the cleaning cycle may be tailored, or optimized, for the pool by determining a maximum length of time between, for example, a rotation of the cleaner and when it next detects a wall of the pool during a designated interval. As another example, deducing information relating to rotation speed of the cleaner also may be useful in determining the tailored cleaning cycle.
