Abstract: A light shield (204) for blocking light traveling toward a PIN photodiode (413) from a glass substrate (314) side is formed of a conductive material, and a reference electric potential (Vr−nVoc) equal to that of a cathode of the PIN photodiode (413) is applied to the light shield (204) from a power supply circuit (266). Thus, inductive noise for a photoelectric conversion device used for an ambient light sensor is further reduced in a display device.

Abstract: Methods for generating a customized spectral profile, which can be used to generate a corresponding filter, lamp or other type of illuminant. A trial spectrum is generated. A reference spectrum is determined or otherwise obtained. A SOURCE spectrum is determined or otherwise obtained. One or more optical indices are calculated using the trial spectrum and one or more of the optical indices are optimized by varying the trial spectrum to generate the customized spectral profile. A radiation force parameter can be used to minimize unsafe build-up of light in spectral regions. Adaptations of color rendering parameters can be used in the optimization process. Smoothing parameters can be used to enable easier design of filter structures. A reflectance camera can be used to measure reflectance data at one or more pixels of a digital representation of an object to be illuminated.

Abstract: A small infrared sensor has a wide infrared light-receiving area (viewing angle), high electromagnetic shielding characteristics, and excellent electromagnetic-wave resistance characteristics. In the infrared sensor, supporting portions are disposed at four corners of a substantially rectangular opening in a package. The supporting portions support an optical filter, disposed so as to cover the opening, at positions that are lower than an upper end of an inner peripheral wall defining the opening. While the optical filter is supported by the supporting portions as a result of inserting a portion of a surface side of the optical filter facing the supporting portions into the opening, the optical filter is secured to the package. The optical filter and the package are joined and secured, and electrically connected to each other through a conductive adhesive.

Abstract: There are provided systems and methods for automatic adjustment of sensitivity threshold settings in an auto-darkening lens. For example, a user may initiate an automatic sensitivity setting process by activating a user interface (e.g., a button, a switch, a slider, etc.). The automatic sensitivity setting process may proceed to gradually increase the sensitivity threshold voltage until it exceeds an optical voltage based on the ambient light. The process may then be terminated. In some embodiments, a hysteresis may be added to the sensitivity threshold voltage to prevent lens flicker. The automatic sensitivity setting process may be implemented in a digital or analog system. These automatic sensitivity setting processes and systems may save time and provide for more precise sensitivity adjustment.

Abstract: Element for the protection and therapy of eyes applied to the transparent vertical surfaces of buildings. The invention is prepared by applying a yellow pigmented filter to the transparent or translucent surfaces of a building in which a subject may be found, and is designed to protect the eyes from the short wavelengths of the visible spectrum in the range 500 to 380 nm. The invention avoids the difficulties and risks of existing ways of protecting healthy eyes or eyes subjected to cataract surgery, and improves the protection of eyes suffering neurodegeneration, simply by applying a filter to the transparent or translucent surfaces of any building in which a subject may be found to provide protection against the neurodegenerative components of light (short wavelengths).
