A system is provided for determining personal ultra-violet (UV) radiation measurements. The system may include a measurement device configured to measure UV irradiation; and a terminal device configured to receive an output of the measured UV irradiation from the measurement device and to display a specific user's personal UV exposure risk level based on at least the measured sun irradiation.

The invention features devices and methods for collecting and measuring light from external light sources. In general, the devices of the invention feature a light diffusing element, e.g., as a component of a light collector, connected by a light conducting conduit, e.g., a fiber optic cable, to a light measuring device, e.g., a spectrometer. This light diffusing element allows, e.g., for substantially uniform light diffusion across its surface and thus accurate measurements, while permitting the total footprint of the device to remain relatively small and portable. This light diffusing element also allows flexibility in scaling of the device to permit use in a wide range of applications.

A photoelectric sensor capable of suppressing breakage of a cable connected to a case body is provided. The photoelectric sensor includes a case body having an accommodation space which accommodates at least one of a light projecting portion and a light receiving portion therein, and a cable which accommodates a cord connected via a control portion to at least one of the light projecting portion and the light receiving portion, and a concave portion recessed toward an inside of the case body is provided in an outer surface of the case body, and the cable is mounted in the concave portion.

Filter wheel assemblies with a single actuation point to control positioning of front and rear optical filter elements simultaneously and to provide high channel density with a plurality of selectable optical filter pairs. A filter wheel assembly may include a plurality of optical filter element pairs arranged around a common axis, wherein each of the plurality of optical filter element pairs includes a first filter element and a complementary filter element, wherein each first filter element and each complementary filter element has a surface having a normal component directed toward an inner portion of the filter wheel assembly.

Methods, systems, and apparatus for a stray-light testing apparatus. In one aspect, the apparatus includes an optical assembly including a spatially extended light source and one or more optical elements arranged to direct light from the spatially extended light source along an optical path, a moveable frame supporting the optical assembly including one or more adjustable alignment features for guiding positioning of the stray-light testing apparatus relative to an onboard camera on a vehicle, and a shrouding mechanism attached to the frame and positioned on the frame such that, when the stray-light testing apparatus is aligned relative to the onboard camera on the vehicle and the optical path of the optical assembly is within the field of view of the onboard camera, ambient light exposure for the onboard camera is below a threshold.

A package component includes a base layer, a sensing layer, a photo-curable adhesive, a cover layer and a first filter structure. The photo-curable adhesive and the sensing layer are disposed on the base layer. The sensing layer includes a sensing unit surrounded by the photo-curable adhesive. The cover layer is disposed on the sensing layer. The first filter structure faces the photo-curable adhesive and is disposed on the cover layer. The first filter structure is configured for transmitting a curing light which is used to cure the photo-curable adhesive, and for reflecting a detectable light which is to be sensed by the sensing unit, where the wavelength of the curing light is different from the wavelength of the detectable light.

A configurable lens cover configured to be disposed over a lens of a sensor to control an area monitored by a sensor and/or to block light from undesirable directions from striking the lens of the sensor. The configurable lens cover includes a collar that has an inner edge which defines a central opening. Further, the configurable lens cover includes detachable panels that extend angularly and inward towards a central axis and the central opening of the configurable lens cover from the inner edge of the collar. The detachable panels may be partially separated from each other along the side edges and top end of each detachable panel. Furthermore, the configurable lens cover includes perforations formed adjacent a bottom end of each detachable panel that is coupled to each other and the collar. The perforations define a living hinge along which each detachable panel is breakable.

Disclosed are an ultraviolet mirror device and a method therefor. The ultraviolet mirror device of the present invention relates to a device that can generate an image obtained by capturing an image of skin in the ultraviolet region. The device can be connected to a portable terminal having a display unit, so as to be used as an ultraviolet mirror. To this end, the ultraviolet mirror device includes an ultraviolet filtering unit provided in a front portion or a rear portion of the lens unit to allow ultraviolet light to pass therethrough and thus enter the image sensor; and an image processing unit providing the portable terminal with multiple digital images generated at a predetermined frame rate per second by the image sensor and thus allowing a moving image to be regenerated in the display unit.

A vehicle detector assembly for detecting solar radiation may include a housing, a fixed plate fixed to an upper surface of the housing in a flat form, a plurality of photo detectors bonded to a surface of the fixed plate, each being connected to a lead having a uniform one-directional inclination structure, and a detector cap fastened to the housing and transmitting sunlight.

A sensor assembly may be mounted in a ceiling used with an associated light fixture. The sensor assembly may include a body including a sensor end and a blade end opposite the sensor end. A sensor may be disposed on the body nearer the sensor end than the blade end. A cutting blade may be disposed on the body nearer the blade end than the sensor end. The cutting blade may be configured to cut an opening in the ceiling. At least one retainer protrusion may be disposed on the body between the sensor and the cutting blade. The at least one retainer protrusion may be configured to retain the sensor assembly in the opening of the ceiling.
