Patent number: 10927841Abstract: 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.Type: GrantFiled: March 17, 2015Date of Patent: February 23, 2021Assignee: DELTA T, LLCInventors: David R. Banks, Richard A. Oleson

Patent number: 10851939Abstract: 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.Type: GrantFiled: November 2, 2018Date of Patent: December 1, 2020Assignee: DELTA T, LLCInventors: Chris Trout, Ethan Beum, Preston Goulson

Patent number: 10801508Abstract: 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.Type: GrantFiled: December 30, 2015Date of Patent: October 13, 2020Assignee: DELTA T, LLCInventors: Jerrill Scott Johnson, Alex Christopher Reed, Marcus Landon Borders, Thomas James Lesser, Jason Hunt Fizer, Adam Glenn Tucker, Stephen Alexander Harper, Ernest John Noble, Ken Siong Tan, Jon Jet Ling, Seng Rui Chan

Patent number: 10746185Abstract: 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.Type: GrantFiled: March 31, 2015Date of Patent: August 18, 2020Assignee: DELTA T, LLCInventors: James M. Desmet, Alex Christopher Reed, Richard A. Oleson, Marshall White, Jason Bishop, Richard Lenser, David R. Banks

Patent number: 10648483Abstract: 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.Type: GrantFiled: January 25, 2017Date of Patent: May 12, 2020Assignee: DELTA T, LLCInventor: Richard A. Oleson

Patent number: 10502216Abstract: A ceiling fan comprising: a fan motor and blade assembly, a mounting tube for suspending the fan motor and blade assembly from a ceiling, and a power supply mounted within the mounting tube configured to power the fan motor. Also a ceiling fan comprising a moulded stator frame, a raised turret integrally moulded within the frame configured to enclose and mount a motor controller, and an external user changeable auxiliary module. Also ceiling fan comprising: a totally enclosed safety extra low voltage fan motor assembly configured to be suspended from an upper side, and a scaling arrangement within the assembly providing a substantial degree of ingress protection against dust and water incident from at least an under side. Also a method comprising providing a ceiling fan comprising moulded stator frame, and mounting an external user changeable auxiliary module to a raised turret integrally moulded within the frame.Type: GrantFiled: July 7, 2014Date of Patent: December 10, 2019Assignee: DELTA T, LLCInventor: Ernest John Noble

Patent number: 10436033Abstract: A fan system includes a motor, a rotatable hub, and a plurality of fan blades. Each of the fan blades includes a substantially rigid spine member, a resilient leading edge member, and a resilient trailing edge member. The leading edge member and trailing edge members are removably coupled with the spine member, such that different leading edge members and different trailing edge members may be chosen to customize the leading and trailing edges of the fan blades. Each fan blade may have more than one type of leading edge member or more than one type of trailing edge member. The leading edge member and trailing edge member may each be coupled with the spine member by urging the leading edge member and trailing edge member in a direction that is substantially perpendicular to the longitudinal axis defined by the spine member.Type: GrantFiled: September 9, 2013Date of Patent: October 8, 2019Assignee: Delta T, LLCInventors: J. Carey Smith, Richard W. Fizer, Richard M. Aynsley, Richard A. Oleson

Patent number: 10309663Abstract: 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.Type: GrantFiled: March 17, 2014Date of Patent: June 4, 2019Assignee: DELTA T, LLCInventors: Christian R. Taber, Mark Toy, Jay Fizer, Ed Quinn

Patent number: 10154565Abstract: A lighting system comprises a plurality of lights, a sensor for measuring a light level associated with each light, and at least one controller for generating a light output from at least one light of the plurality of lights. The controller is adapted for adjusting the light output from the at least one light by an incremental amount to bring the measured light level closer to a target light level, which may correspond to an overall brightness for the space including the lights. Related methods are also disclosed.Type: GrantFiled: June 28, 2017Date of Patent: December 11, 2018Assignee: DELTA T, LLCInventors: Jonathan William Wiley Olsen, Stephen Alexander Harper, Adam Glenn Tucker, Thomas James Lesser, James Tristan Miller, Mitchell Thomas Kiser, Marcus Landon Borders, Warner Lee Wells, Kristjen Ejvind Kjems, Jason Robert Bishop, Paul Frederick Wigler

Patent number: 10054131Abstract: A fan assembly comprises a hub and fan blades. The hub includes a plurality of sockets configured to receive complementary mounting blocks of the fan blades. The mounting blocks each include at least one tapered shoulder portion. The mounting blocks are each tapered along three dimensions. Each mounting block comprises a rear face seated against a complementary rear face of the corresponding socket and a front face that is exposed relative to the hub. A cap secures the fan blades to the hub. The fan assembly may also include one or more shrouds positioned about the fan blades. The one or more shrouds may be substantially straight cylinders, may be flared or bell-shaped, may comprise a cage, may have any other suitable configuration, or may be omitted altogether.Type: GrantFiled: March 24, 2010Date of Patent: August 21, 2018Assignee: DELTA T, LLCInventors: Richard M.
