ABSTRACT:
A remotely operable motorized fan includes an elongated support shaft that has top and bottom end portions, and a housing that defines a cavity therein and includes a tubular lower flange positioned about the top end portion of the support shaft. The housing includes monolithically formed platforms to which the power mechanism and the sensing mechanism are secured. A sensing mechanism is included for detecting a mobile target zone remotely located from the housing. The system further includes a power mechanism for rotating the housing about the support shaft based upon a location of the target zone. The power mechanism is electrically coupled to the sensing mechanism such that the housing automatically pivots without requiring a user input.
