Abstract
Abstract A portable fan is provided with a remote control assembly to facilitate its use by handicapped persons. The switch on the fan is operated by a radio controlled receiver, and a hand held transmitter is designed to permit a user to select multiple fan speeds and direction of blade rotation. Additionally, the transmitter emits audible beeps so as to allow the use of the remote fan control by blind individuals.
