Abstract
Abstract A photosensitive surface is enclosed behind a wall formed with a vertically open slit which forms with the surface a vertical angle of 80*. This slit is open about 3* and is displaced horizontally past the surface through at least 150* so as to let parallel rays of sunlight fall onto this surface and suppress diffuse nonparallel ground light. The wall can be part of a cylindrical or frustoconical element rotated about a fixed photosensitive surface, e.g., a photoresistor, photocell, or photodiode, which is used to control an awning, roller blinds, or the like.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
134 words
The combination with a load comprising a motor and a sun shield of the jalousie, window blind, awning and like type driven by said motor, of a sunlight detector for controlling said load and comprising: sensing means having a photosensitive surface for emitting an electrical output on irradiation of said surface by light; a housing surrounding said surface and having an annular displaceable wall formed parallel to said surface with a generally vertically elongated slit-like window constituting the only light entrance into said housing; means for angularly displacing said wall and thereby displacing said slit transversely to itself about an upright axis and at a constant distance from said surface through an angle of at least 150*; and means connecting said sensing means and said load for operating said load according to said output.
Claim 2
Dependent Claim
134 words
The combination with a load comprising a motor and a sun shield of the jalousie, window blind, awning and like type driven by said motor, of a sunlight detector for controlling said load and comprising: sensing means having a photosensitive surface for emitting an electrical output on irradiation of said surface by light; a housing surrounding said surface and having an annular displaceable wall formed parallel to said surface with a generally vertically elongated slit-like window constituting the only light entrance into said housing; means for angularly displacing said wall and thereby displacing said slit transversely to itself about an upright axis and at a constant distance from said surface through an angle of at least 150*; and means connecting said sensing means and said load for operating said load according to said output.
Claim 3
Dependent Claim
20 words
The combination defined in claim 1, further comprising a fixed support, said surface being planar and carried on said support.
Claim 4
Dependent Claim
19 words
The combination defined in claim 2 wherein said window is vertically elongated and said means displaces said wall horizontally.
Claim 5
Dependent Claim
32 words
The combination defined in claim 3 wherein said wall is a body of revolution having an axis at said surface, said means for displacing serving to rotate said wall about said axis.
Claim 6
Dependent Claim
23 words
The combination defined in claim 4 wherein said wall is cylindrical and is formed with a pair of such slit-like windows diametrically apart.
Claim 7
Dependent Claim
29 words
The combination defined in claim 3 wherein said wall is a body of revolution having an axis, said means for displacing serving to rotate said wall about said axis.
Claim 8
Dependent Claim
18 words
The combination defined in claim 6, further comprising a plurality of such surfaces angularly equispaced about said axis.
Claim 9
Dependent Claim
18 words
The combination defined in claim 7 wherein said axis is vertical and said slit-like window is vertically elongated.
Claim 10
Dependent Claim
18 words
The combination defined in claim 1 wherein said window is open at most 3* relative to said surface.
Claim 11
Dependent Claim
22 words
The combination defined in claim 1, further comprising a displaceable support, said surface and said wall being fixedly mounted on said support.
Claim 12
Dependent Claim
29 words
The combination defined in claim 10 wherein said support is rotatable about an upright axis, said means for displacing being effective to rotate said support about said upright axis.
Claim 13
Dependent Claim
64 words
The combination defined in claim 11 wherein said walL is formed with a second such slit-like window above the first-mentioned window, said detector further comprising a second surface on said support and a partition between said windows and said surfaces, whereby light from said first window falls only on the first-mentioned surface and light from said second window only falls on said second surface.
