    Abstract: An anti-glare rearview mirror assembly and a reflectance control method thereof are disclosed. The assembly includes an electrochromic rearview mirrors, two rearward light sensors, and a comparative controller. The sensors receiving a first rearward light from a first specified region and a second rearward light from a second specified region at the same time point, respectively, wherein the first and second specified regions partially overlap with each other. The intensities of the first and second rearview mirror light are compared to obtain a light difference. The reflectance of the anti-glare rearview mirror is adjusted according to the light difference.

    Abstract: Guiding and focusing errors in a stellar telescope are detected automatically using photoelectric techniques. Light from a guidestar, collected by the telescope, is directed out of the telescope as a converging focusable beam and impinges on a highspeed chopping element. Guiding errors are detected by measuring the intensity of the emerging chopped light. An AC component in the output signal indicates an error. Focusing errors are detected by measuring the intensity of the emerging chopped light after it strikes and is partly blocked by a knife edge positioned where the focus should occur. An AC component in the output signal indicates an error. Both output signals are either read on meters or fed into servosystems which move portions of the telescope to compensate for the errors.

    Abstract: A light sensor is provided that includes an exposed light transducer for accumulating charge in proportion to light incident thereon over an integration period; and a light-to-pulse circuit in communication with the exposed light transducer, the light-to-pulse circuit operative to output a pulse having a pulse width based on the charge accumulated by the exposed light transducer. The light-to-pulse circuit may include a one shot logic circuit that contributes to generation of the pulse. The light sensor may include an input/output pad, a capacitor provided at the input/output pad for blocking static electricity, an input low pass filter provided at the input/output pad for blocking electromagnetic interference, and/or a bandgap voltage reference circuit connected to a power source having a supply voltage level in a range of about 3.3V to about 5.0V, and for generating a set of stable reference voltages throughout the supply voltage level range.

    Abstract: Systems and method for detecting and measuring light emitted from a sample and having a large dynamic range, e.g., a range of luminous intensity covering six or more orders of magnitude, that may be difficult to fully detect using a single detector with a limited detection range. Simultaneous measurement of the emitted light in two intensity ranges is performed using two detectors, e.g., one including a photomultiplier tube (PMT) and the other including a solid state detector such as a photodiode. A beam splitting element directs light emitted from a sample under investigation to both detectors simultaneously such that a portion of the light impinges on the first detector and a second portion of the light impinges on the second detector. A processor receives output signals from the two detectors and provides an output representing the luminous intensity of the sample over a detection range greater than the detection range of each individual detector, thereby providing a detection system having an enhanced dynamic range.

    Abstract: A rearview assembly for a vehicle is provided that includes: a housing configured for mounting to the vehicle; a rearview element disposed in the housing that displays images of a scene exterior of the vehicle; a light sensor assembly disposed in the housing; and a controller for receiving the electrical signal of the light sensor and for adjusting a brightness of the images displayed by the rearview element. The light sensor includes a light sensor for outputting an electrical signal representing intensity of light impinging upon a light-receiving surface of the light sensor, and a secondary optical element configured to receive light, wherein the light passes through the secondary optical element to the light sensor, the secondary optical element including a tint material that is substantially color neutral for attenuating light passing therethrough.
