Abstract: An attachment for a pool vacuum includes a housing and a brushroll at least partially extending from the housing. The brushroll has a plurality of bristles configured to rotate about a first axis. The attachment further comprises a paddle wheel disposed in the housing. The paddle wheel is configured to rotate about a second axis that is parallel to the first axis. The attachment further comprises a torque transmission member coupling the brushroll and the paddle wheel. In response to rotation of the paddle wheel about the second axis, the torque transmission member is configured to rotate the brushroll about the first axis.

Abstract: A battery backup device for a garage door opener. The battery backup device includes a housing and one or more accessory ports for receiving one or more accessories. The battery backup device is configured to use received AC power to provide power to the one or more accessories. The battery backup device is also configured to pass AC power through to an AC power outlet. The AC power outlet is configured to receive a standard AC power plug from a garage door opener. When AC power is available to the battery backup device, AC power may be passed through the battery backup device to the AC power outlet. When AC power is not available to the battery backup device, the battery backup device is configured to invert DC power from a battery pack to produce AC power. The AC power may then be provided to the AC power outlet.

Abstract: A ceiling fan may include a hub having a first end, a second end opposite the first end, a central axis extending through the first end and the second end, and an accessory interface disposed proximate to the first end or the second end. The ceiling fan may also include a subframe disposed proximate to the hub, the subframe being rotatable with respect to the hub about the central axis, a plurality of fan blades extending outwardly from the subframe, and an accessory unit, the accessory unit being removably coupled to the accessory interface of the hub.

Abstract: Devices, systems, and methods for controlling a ceiling fan are disclosed. One example system may include a sensor device and a remote device. The remote device may be configured to generate an instruction based on the data obtained from the sensor device, and transmit the instruction via the communications network to a fan. The fan may include a hub, a plurality of fan blades extending from the hub, and a motor supported by the hub. The fan may further include a wireless transceiver supported by the hub. The wireless transceiver may be configured to access the communications network for communicating with the remote device. The fan may further include an electronic processor supported by the hub. The electronic processor may be configured to control an operation of the fan based on receiving the instruction from the remote device via the wireless transceiver.

Abstract: A portable forced air heater including a housing, a heating element located within the housing, a sensor configured to sense a characteristic of the portable heater, a communications device configured to communicate with an external device, and a controller having an electrical processor and memory. The controller is configured to receive, from the sensor, the characteristic of the portable heater, and output, via the communications device, a signal indicative of the characteristic of the portable heater to the external device.
