At least one fan blade includes a first end portion coupled to the rotatable hub and a second end portion radially distant from the rotatable hub. At least one ion generator is carried by the second end portion of the at least one fan blade, such as by a winglet associated therewith. A stationary tube passes through the rotatable hub including a conduit for transmitting power. A rotary coupling is also provided for transmitting power from the conduit to the at least one ion generator.

Abstract: A system for controlling the circulation of air in an indoor area of a structure including a door or window. A fan for circulating the air within the indoor area is combined with a first sensor for sensing a temperature of a surface of an object in the indoor area. A controller controls the operation of the fan based on the surface temperature sensed by the first sensor, and also regulates a radiant heater for heating the surface or the object. The controller may also or alternatively be adapted for controlling the fan based on an indication that it is raining external to the structure, an HVAC unit, or a dehumidifier. Related methods are also disclosed.

Abstract: A fan mount includes a first part movable relative to a second part. A retainer is connected to the second part of the fan mount above the first part for restricting the movement of the fan relative to the fan mount. The first part may be a ball member having a depending portion with an hourglass shape. A safety connector may be provided, and a retainer connected to the second part of the fan mount for retaining the safety connector. A cover may also be provided for mounting to the second part, the cover including a central opening for receiving the support. A trim piece is adapted for telescoping within the opening of the cover.

Abstract: A system for displaying the produce for sale and at least one sensor for sensing a parameter associated with the display and generating an output representative of the parameter. An overhead fan located in the space above the display regulates the airflow over the display. A controller is provided for controlling the fan based on the output of the sensor.

Abstract: A fan mounting system (30) may include supplemental mounting components for installations where fan (10) will be located in a geographic region that encounters frequent seismic activity. These supplemental components may provide additional reinforcement and stability to fan (10), enabling fan (10) to remain secured to a ceiling or other structure during seismic events. Such a supplemental system may comprise cables (410) extending between and connecting the fan (10) to structures, such as ceiling joists (450). Related methods are also disclosed.

Abstract: A fan system includes a hub configured to rotate and a plurality of fan blades mounted to the hub. A motor is operable to rotate the hub. A motor controller in communication with the motor is configured to control operation of the motor. A control panel in communication with the motor controller has an input port for receiving data relating to operation of the fan system.

Abstract: A system and related method are disclosed for controlling condensation in a space. The system includes a fan and one or more sensors for sensing environmental conditions such as temperature and relative humidity associated with the space and/or objects within the space. For instance, the sensors may sense a surface temperature of an object within the room. The system also includes a controller capable of receiving measurements from the sensor(s) and controlling the fan based on the sensed information. The system may additionally include a heater and/or a damper for transferring outside air into the space, either of which may be controlled by the controller based on the measurements.

Abstract: A fan includes a temperature sensor, such as a passive infrared sensor, for sensing temperature at a location remote from the fan, such as at a floor, ceiling, or wall, or simply external to the fan housing. This may avoid the influence of heat generated from components of the fan, such as the fan motor or controller for controlling the operation of the fan. A mounting arrangement for forming a connection between two parts, such as components of a fan, is also described.

Abstract: A dynamic fan mount for supporting the fan has a first part movable relative to a second part. A restrictor for restricting lateral movement or swaying of the fan is provided. In one embodiment, the restrictor is a cushion connected to the second part of the dynamic fan mount for dampening the movement of the fan relative to the mount. Related methods are also disclosed.

Abstract: A system for controlling thermal comfort in a space is provided with a variable mode of operation. The system may include a conditioner for conditioning air in the space, and a sensor for measuring a temperature in the space. A controller is provided for controlling the conditioner based on the temperature sensed by the sensor, and a fan for circulating air within the space is regulated based on the temperature sensed by the sensor. A related system for controlling a fan based on height is also provided, as is a system and method for easily and efficiently determining the height of a fan using a simple camera, such as one on a “smart” phone. A further aspect pertains to a controller, such as for example a portable handheld device, having a user interface adapted for suggesting an increase in a set point temperature of a thermostat based on the selected speed of the fan.

Abstract: A fan, such as a ceiling fan, includes a learning mode of operation. This learning mode may permit a user to input a desired speed for the fan for a given condition, such as ambient temperature, and adjustments for other conditions would be automatically determined based on the user input. A subsequent selection of fan speed at that condition (such as, for example, for a different user) or a different condition setting would also be obtained, either during initialization or later, and then used as an updated measure of the desired fan speed for the condition. Related methods of controlling the operation of a fan are also disclosed.

Abstract: A fan may be designed for the strategic diversion of moisture through or around a housing enclosing a controller and/or a motor. The enclosure may include one or more paths for directing moisture away from the controller or the motor. For instance, the housing may include a gap between a support structure and the housing for preventing moisture from entering the housing. The housing may also include a hollow structure for directing fluid through the housing. Additionally, the housing may include one or more channels, raised walls, gutters, and shields for preventing fluid, such as liquid water, from entering an enclosure for the controller or motor.
