Abstract
Abstract A ceiling mounted fan and light assembly remotely controlled by radio signals propagated by a remote transmitter with the transmitter having independent controls for the fan and light respectively. The receiver has two channels and is responsive to the signals for setting the power supplied to the fan drive motor and light respectively at different levels so that the rotational speed of the fan may be set at various different levels and the illumination of the light may be set at various different levels.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
247 words
A fan assembly (20) for being mounted to a ceiling and suspended therefrom and comprising; support means adapted for connection to a ceiling and an electrical power outlet, a fan blade means (22) rotatably supported by said support means, an electrical drive motor (24) supported by said support means for rotating said fan blade means (22), an electrical light means (26) supported by said support means for selectively providing illumination, said assembly characterized by radio signal receiver means (48) electrically connected respectively to said drive motor (24) and said light means (26) and adapted for electrical connection to the electrical power outlet for controlling the electrical power supply to said drive motor (24) and said light means (26) independently of one another in response to predetermined first and second radio signals, said receiver means including electrical current regulator means (60,61,62,63) for establishing the magnitude of electrical power supplied to said drive motor (24) and said light means (26) respectively over a predetermined range of power in response to said first and second radio signals respectively to establish the speed of rotation of said drive motor (24) for said fan blade means (22) in response to the employment of said first radio signal and to turn said light means (26) ON and OFF and establish the degree of illumination of said light means (26) among a plurality of different degrees of illumination over said predetermined range of power in response to the employment of said second radio signal.
Claim 2
Dependent Claim
247 words
A fan assembly (20) for being mounted to a ceiling and suspended therefrom and comprising; support means adapted for connection to a ceiling and an electrical power outlet, a fan blade means (22) rotatably supported by said support means, an electrical drive motor (24) supported by said support means for rotating said fan blade means (22), an electrical light means (26) supported by said support means for selectively providing illumination, said assembly characterized by radio signal receiver means (48) electrically connected respectively to said drive motor (24) and said light means (26) and adapted for electrical connection to the electrical power outlet for controlling the electrical power supply to said drive motor (24) and said light means (26) independently of one another in response to predetermined first and second radio signals, said receiver means including electrical current regulator means (60,61,62,63) for establishing the magnitude of electrical power supplied to said drive motor (24) and said light means (26) respectively over a predetermined range of power in response to said first and second radio signals respectively to establish the speed of rotation of said drive motor (24) for said fan blade means (22) in response to the employment of said first radio signal and to turn said light means (26) ON and OFF and establish the degree of illumination of said light means (26) among a plurality of different degrees of illumination over said predetermined range of power in response to the employment of said second radio signal.
Claim 3
Dependent Claim
96 words
An assembly as set forth in claim 1 further characterized by including transmitter means (FIG. 10) having manually actuatable fan control means (54) for transmitting a first predetermined radio signal to said receiver means (48) in response to actuation of said fan control means for remotely controlling the electrical power supply to said drive motor (24) and manually actuatable light control means (56) for transmitting a second predetermined radio signal to said receiver means (48) in response to actuation of said light control means for remotely controlling the electrical power supply to said light means (26).
Claim 4
Dependent Claim
75 words
An assembly as set forth in claim 2 further characterized by said regulator means including memory means (61) for establishing the level of magnitude of power and for providing a predetermined reference level within said predetermined range of power supplied to said drive motor (24) and said light means (26) respectively and reset means (65, 66) for resetting said memory means to said reference level in response to the employment of said respective radio signals.
