摘要: A sensor (50) for determining the magnitude and intensity of solar radiation. The apparatus includes a diffuser (2) which provides radiation through channels (60a, 60b, 60c, 60d) within an elongated channeled member (5) onto photodiodes (54a, 54b, 54c, 54d). Each photodiode (54a, 54b, 54c, 54d) is optically isolated from other photodiodes. The diffuser (2) is arranged and constructed so as to receive radiation within 360 degrees of the surrounding environment.

摘要: An improved ambient light sensor (20) is provided. Light (105) passes to at least two photosensors (30, 35) with different peak response frequencies. A controller (80) accepts output signals from the photosensors (30, 35) and operates vehicle systems (e.g., headlights (70) or environmental controls (75) accordingly. The controller (80) may distinguish between natural and artificial light, so that headlights (70) are illuminated while a vehicle passes through a well lit tunnel, or is exposed to lights from another vehicle.

摘要: The present invention relates to a dual zone solar sensor (10) incorporating a calibratable diffuser (50) overlying a vertically oriented circuit board (20) having at least one photodetector (21, 22) affixed to either side of the circuit board (20) in a vertical plane. Each detector (21, 22) preferably has a mutually exclusive hemispherical view. By mounting the photodetectors (21, 22) in the vertical plane, the dual zone solar sensor device (10) is capable of providing information about the intensity of a source of incident solar radiation and the relative position of that source of radiation. While the angular responses of the photodetectors (21, 22) in their vertical orientation are very close to those desired by skilled artisans for a dual zone sensor, the addition of a diffuser (50) that is slidable, and therefore calibratable, provides a method by which the angular response of each photodetector (21, 22) may be permanently calibrated to achieve a precise desired angular response. The present inventive combination of features eliminates the need for complex and bulky electronic signal processing circuitry and decreases the number of parts necessary to achieve functions previously achieved only by larger sensors having a far greater number of component parts.

摘要: A sensor (20, 100, 200, 300) for detecting the approach and exit of a vehicle (42) to a tunnel (46). In one embodiment there is a sensor (20, 100, 200, 300) with a photodiode (22a) that receives light through an inclined channel (30, 30') or aperture (32, 332, 432). The channel provides a field of view (44, 344, 31) ahead and above the vehicle. The photosensor (22a) is thus sensitive to the change in light from this field of view (44, 344, 31) as a vehicle enters (46a) and exits (46b) a tunnel (46). Some embodiments of the present invention include a second photosensor (22b) with a wider field of view (112, 112'', 111) for detecting ambient light.
