摘要： A fan includes a motor, a rotatable hub coupled to the motor, and at least one fan blade. The at least one fan blade includes a first end coupled to the rotatable hub, a second end, a leading edge, a trailing edge, a passage extending from the first end to the second end, and a winglet attached to the second end. At least one flexible strap extends through the passage of the at least one fan blade. The flexible strap is coupled at a first end to the rotatable hub and coupled at a second end to the winglet, such as to an inner portion thereof within the passage.

摘要： An apparatus prevents electrical arcing between a motor including a rotating shaft and an associated bearing within a motor housing. A brush is formed of a conductive fabric for electrically connecting the rotating shaft to the motor housing. The conductive fabric may comprise randomly arranged or non-woven conductive fibers in contact or woven conductive fibers. The fabric may comprise a wool or felt. The apparatus may be applied to a fan. A related method is also disclosed.

摘要： An apparatus is provided for controlling environmental conditions using a fan and a light in connection with a building having a space including a partition, such as a wall. The apparatus may include a control adapted for being mounted to the partition and for coordinating the control of the fan and the light based on a sensed condition, such as temperature or occupancy. Groups of like devices for controlling environmental conditions may be similarly controlled, such as using control. Control may also provide an indication of an operational state of the device(s) controlled by it, or provide for control based on a preference of one or more people upon detecting their presence. Related methods are also described.

摘要： A fan is for improving air quality, such as in an indoor environment. The fan includes a motor and a rotatable hub coupled to the motor. 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.

摘要： 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.

摘要： 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.

摘要： 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.
