Abstract: A valve actuator may include a valve control shaft extending at least partially through a housing of the valve actuator, wherein the valve control shaft is configured for controlling a valve position of a diverter valve. A first cam wheel may be included, where the first am wheel at least partially surrounds the valve control shaft. A first cam may be fixed to the first cam wheel, and a first microswitch may have an actuator located in a rotational path of the first cam. The valve actuator may also include a second cam wheel at least partially surrounding the valve control shaft, where a second cam is fixed to the second cam wheel, and where a second microswitch has an actuator located in a rotational path of the second cam.

Abstract: An operational efficiency apparatus comprising a sensor connected to a heat transfer system to detect efficiency of system and a display electrically connected to the sensor for indicating efficiency of the system based on data detected from the sensor.

Abstract: A combination transformer junction box for use with pool and/or spa lighting and/or other low-voltage devices, which combination transformer junction box includes a waterproof housing having a base and a cover, a first set of terminals for low voltage, a second set of terminals for high voltage separated from the first set of terminals by a barrier, and a transformer disposed upon the base such that the transformer is within the base and does not occupy a volume defined by the cover. In one aspect a plurality of the combination transformer junction boxes may be provided together in a daisy-chain linked form configured for controlling a plurality or larger plurality of lighting and/or other low-voltage devices.

Abstract: A method for controlling the application of a voltage supply to an electrical load is disclosed. A characteristic of the voltage supply is determined. In response, the method causes disconnection of a control signal from a contactor. Disconnecting the control signal causes the contactor to disconnect the voltage supply from the electrical load.

Abstract: An automation network includes automation network devices connected to the network and a system layer interface that interfaces with a transport layer and an application layer of the automation network. The system layer interface includes messaging command libraries configured to implement human-readable messages for the automation network devices, where the automation network devices include at least one message output device. The system layer interface may provide commands and functions to establish messaging in the network, the length of supported messages, and scrolling of messages on output display devices.

Abstract: An automation network includes automation network devices connected to the network and a system level interface that interfaces with a transport layer and an application layer of the automation network. The system level interface includes proxy command libraries configured to designate a proxy device from the automation network devices. The proxy device accepts commands or messages to be transmitted to another automation network device.

Abstract: An automation network includes automation network devices connected to the network and a system layer interface that interfaces with a transport layer and an application layer of the home automation network. The system layer interface includes command libraries configured to upgrade a remote network device. The automation network queries the network devices to determine if there are lost network devices or newly added network devices. The automation network may update a new remote device with scene information related to any lost network devices.

Abstract: An automation network includes automation network devices connected to the network and a system level interface that interfaces with a transport layer and an application layer of the automation network. A method is disclosed that programs an automation network device in communication with an automation network, where the automation network includes an access point coupled with an external network. The method includes receiving application upgrade data at the access point, where the application upgrade data includes upgrade data associated with a target automation network device in communication with the automation network. Application upgrade data is transmitted through the home to the target automation network device. A next application upgrade data packet to be transmitted across the automation network is requested from the target automation network device.

Abstract: A home automation protocol system provides a network consisting of a number of node devices, controllers, and servers for storing information about node device settings and scene settings in a home environment is provided. The node devices are controlled by the controllers, in that the node devices are set to create scenes, which are stored in a scene server, while the operational states of the node devices are stored in a status server. The status server and scene server may be provided as separate units. The home automation protocol network is controlled by sending commands to the devices and servers, and new devices and controllers are added or updated, and new scenes are programmed. The network protocol allows devices running different protocols to be incorporated into the network.

Abstract: A device is disclosed for connecting electrical devices. The device may include a transformer, a connector post with a nut, and a conductor. The conductor may be positioned from the transformer to an opening of the connector post. The conductor may be a metal plate. The nut may clamp the device lead to the conductor to electrically connect them. The nut may be retained on the post, even when unsecured from the post.
