专利汇可以提供Sun tracking control apparatus专利检索，专利查询，专利分析的服务。并且Electrical apparatus enabling control of sunlight collection or transmission which functions in response to sun position. The apparatus consists of quadrant sensitive sun sensors which function in coaction to produce definitive output pulses for input to logic circuitry. Outputs from the logic circuitry are applied through driver circuitry and shading control mechanism to track the sun''s travel either clockwise or counterclockwise throughout daylight periods.，下面是Sun tracking control apparatus专利的具体信息内容。

4. Apparatus as set forth in claim 2 which is further characterized in that: said quadrant sensor means includes a first and second plurality of sensors each disposed on opposite sides of said shade plate.
5. Apparatus as set forth in claim 1 wherein said logic circuit means comprises: quadrant sensor logic receiving as input said sun quadrant signal output to provide plural sun quadrant signals indicative of sun presence in said first and second quadrants; track sensor logic receiving as input said track signal output to provide plural tracking signals indicative of requirement for one of clockwise and counterclockwise tracking movement by said vanes; and logic circuitry receiving as input all of said sun quadrant signals and tracking signals to generate one of a clockwise and counterclockwise command output to said control means.
6. Apparatus as set forth in claim 5 wherein said control means further comprises: voltage comparator amplifier means receiving each of said clockwise and counterclockwise command outputs to generate an opposite polarity voltage; and polarity responsive amplifier means receiving said voltage to energize reversible electrical drive motor means to drive said vanes in one of clockwise and counterclockwise direction.
7. Apparatus as set forth in claim 1 wherein said sun sensor means further comprises: a supply voltage source; a track 1 sensor disposed in said sun sensor means connected to said supply voltage and in series connection with a track 3 sensor disposed in said quadrant sensor means and generating an output counterclockwise track signal at said connection; and a track 2 sensor disposed in said sun sensor means connected to said supply voltage and in series connection with a track 4 sensor disposed in said quadrant sensor means and generating an output clockwise track signal at said connection.
8. Apparatus as set forth in claim 1 wherein said quadrant sensor further comprises: a source of supply voltage; a first sensor disposed on a first side of said shade plate connected to said supply voltage and in series connection with a second sensor disposed on the second side of said shade plate and generating an output sun quadrant one signal at the connection; and a third sensor disposed on the second side of said shade plate connected to said supply voltage and in series connection with a fourth sensor disposed on the first side of said shade plate and generating an output sun quadrant two signal at the connection.
9. Apparatus as set forth in claim 7 wherein said quadrant sensor means further comprises: a source of supply voltage; a first sensor disposed on a first side of said shade plate connected to said supply voltage and in series connection with a second sensor disposed on the second side of said shade plate and generating an output sun quadrant one signal at the connection; and a third sensor disposed on the second side of said shade plate connected to said supply voltage and in series connection with a fourth sensor disposed on the first side of said shade plate and generating an output sun quadrant two signal at the connection.
10. Apparatus as set forth in claim 9 wherein said logic circuit means comprises: quadrant sensor logic receiving as input said sun quadrant one and sun quadrant two signals to provide plural sun quadrant signals indicative of sun presence in said first and second quadrants; track sensor logic receiving as input said counterclockwise and clockwise track signals to provide plural tracking signals indicative of requirement for one of clockwise and counterclockwise tracking movement by said vanes; and logic circuitry receiving as input all of said sun quadrant one and sun quadrant two signals and counterclockwise and clockwise track signals to generate one of a cLockwise and counterclockwise command outputs to said control means.
