摘要： A system for detecting the presence of rain droplets on a windshield employs a source of radiant energy, such as an LED (70), and a photodetector installed on the instrument panel of a vehicle. The LED (70) and the photodiode (85) are arranged with respect to one another such that light from the LED (70) cannot reflect directly off the windshield (81) onto the photodiode (85). Only when the light from the LED is back scattered by an environmental condition, such as the raindrops on the exterior (82) of the windshield, the condensation of moisture on the interior (80) of the windshield, or the presence of smoke in the cabin, will the photodiode receive the light from the LED. Each of these environmental conditions has a predeterminable characteristic signature that permits the processing of data to detect same. An ambient light signal is subtracted from the combination of the rain and ambient light signals by pulsed operation of the LED and subtracting the ambient light signal, which is detected when the LED is dark, from the combined LED and ambient light signal which is present when the LED is illuminated. A further LED (100) is provided to effect a fog detection system that detects condensation on the interior of the vehicle windshield. The further LED (100) illuminates the photodiode in a manner whereby the light on the photodiode is reduced when condensation is present. Also, a monitoring arrangement that employs a separate light sensor provides compensation for variances resulting from component aging and thermal influences.

摘要： A twilight sensor (10) for controlling the headlamps (21) of vehicles employs a photodiode (11) having a predetermined spectral response and a diffuser (16) which also has a predetermined spectral response, the spectral responses being combined to achieve an overall spectral response which corresponds to that of the human eye. With this arrangement, the headlamps (21) of a motor vehicle are turned on and off under different ambient light conditions, in a manner which corresponds to the perception of the driver. In addition, the invention employs a control system (20) which turns the lights on rapidly after the vehicle enters a tunnel.

摘要： A system for detecting the presence of rain droplets on a windshield (17) employs a source of light, such as an LED (11), and a photodetector (12) installed on the dashboard (13) of a vehicle.

Only when the light from the LED is backscattered by an environmental condition, such as the raindrops (25) on the exterior of the windshield (17), the condensation of moisture on the interior of the windshield (17), or the presence of smoke in the cabin, will the photodiode (12) receive the light from the LED (11).

摘要： Un agencement de photodétecteurs produit un signal électrique sensible à la position d'une source de lumière en utilisant un masque (15) situé à une hauteur prédéterminée au-dessus d'une pluralité de photodétecteurs (D1,1), (D1,2), (D2,1), (D2,2), de telle façon que, à mesure que le soleil se déplace par rapport à l'appareil, une ombre, sensible à la position du soleil, est projetée. Un appareil, fabriqué conformément à l'invention, comporte une pluralité de photodétecteurs, chacun présentant une surface respective pratiquement plane photosensible permettant de recevoir la lumière du soleil sur un éventail de positions prédéterminé. Dans un mode de réalisation préféré où l'on recherche la compacité, les surfaces planes photosensibles sont disposées de manière sensiblement coplanaire les unes par rapport aux autres. Le masque à lumière possédant des sections opaques (16) et transparentes (17) est disposé de façon à recouvrir les surfaces pratiquement planes photosensibles afin de déterminer la caractéristique de sensibilité à la position de l'appareil. Dans certains modes de réalisation, un diffuseur est interposé entre le masque à lumière et les photodétecteurs. Les caractéristiques de réponse de l'appareil peut être déterminée par analyse géométrique, ou de manière empirique en utilisant des valeurs qui peuvent être conservées dans une table à consulter.

摘要： A photodetector system (10) for producing electrical signals responsive to the orientation of a light source, such as the sun, with respect thereto utilizes in certain embodiments a diffuser (11) to eliminate position-dependent sensitivities of the photocathode. The extent to which the diffuser (11) or the photocathode itself is exposed to the incident radiation can be controlled by a shroud (12) or by applying an absorptive coating (32) in a predetermined pattern on an absorber cap (40), or on the diffuser (11) directly. In a shrouded embodiment of the invention, the diffuser element (11) is arranged within a mountable body (13) with the shroud (12) extending thereover. The shroud (12), by its configuration and its height above the photodetector, defines the range of angles of elevation and azimuth at which the diffuser (11) can be illuminated. Such angles can also be controlled with printed or sprayed-on markings (30) on the diffuser or absorber cover (11) which form an opaque coating so as to prevent light transmission over predetermined regions. In addition to transmissive and nontransmissive regions, a fine dot pattern (32) may be applied to the diffuser or the absorber cover (11), which may be translucent or transparent, or to the diffuser (11) directly, so that only partial transmission of the light can be achieved therethrough. The absorber cover (11) may be provided with a light absorbing coloration or dye therethrough, and have a predetermined variation in thickness, so that the amount of light transmitted therethrough is responsive to the thickness at the point of incidence of the light. Thus, the light which is transmitted to the photodetector is modulated in response to the orientation of the light source with respect to the photodetector system.

摘要： A combined ambient light magnitude and light source direction sensor controls the headlamps and cabin climate of a vehicle. The combined unit employs a photodiode (33) having a predetermined spectral response and a diffuser (36) which also has a predetermined spectral response, the spectral responses being combined to achieve an overall spectral response which corresponds to that of the human eye. With this arrangement, the headlamps of a motor vehicle are turned on and off under different ambient light conditions, in a manner which corresponds to the perception of the driver. In addition, a light modulator (37) provides the combined unit with a sensitivity to the angular location of the sun with respect to the vehicle in which the unit is installed. Such angular sensitivity facilitates in determining the portion of the interior of the vehicle undergoing thermal loading by the sun, and facilitates a corresponding adjustment of the climate control system.
