Abstract: A filter includes a first filter having a recess, and a second filter made of a material different from that of the first filter. The second filter has a housed portion to be housed in the recess of the first filter such that the second filter is removable relative to the first filter. The housed portion of the second filter may correspond to either the entirety or a portion of the second filter. This structure facilitates formation of the filter having a simple structure and implementation of desired light distribution of two or more different light beams.

Abstract: A motion detection system including: an infrared light source that emits infrared rays; a camera that captures a subject using infrared rays reflected by the subject; a memory that stores a plurality of pieces of outline data an output device that outputs information associated with a state of the subject; and a controller that controls the infrared light source, the camera, the memory, and the output device, wherein the controller performs the following: makes a comparison between an outline of the subject captured by the camera and the pieces of outline data; selects, from among the pieces of outline data, a piece of outline data which resembles the outline of the subject captured by the camera; and causes the output device to output information associated with a state of the subject corresponding to the selected piece of outline data.

Abstract: In an information presenting method, visible light including unique information, which is unique to a passenger carrier and specific to a location of the carrier, is emitted. The light is received in the passenger space and the unique information is obtained. One or more stop points at which the carrier is currently stopped or is to subsequently stop are obtained. The one or more stop points are derived from the unique information. An alighting point at which a user is to alight from the carrier is obtained. Whether the alighting point is included in the one or more stop points is determined. Alighting information notifying the user to alight from the bus is presented to the user via a terminal, when the alighting point is determined to be included in the one or more stop points.

Abstract: A light-emitting device includes: a holder having an elongate shape and flexibility; and a flat light-emitting element held by the holder and having a rectangular shape and flexibility. The holder includes a frame portion extending in a longitudinal direction of the holder, and a holding part protruding from the frame portion in a plan view. The frame portion of the holder and the flat light-emitting element overlap in a lateral-view direction, and the flat light-emitting element is joined to and held by the holding part.

Abstract: A light-emitting element lighting device includes: a step-down chopper circuit which outputs a current that flows to a light-emitting element; a current command circuit which selects between a rated mode for passing a rated current for turning ON the light-emitting element and a detection mode for passing an abnormality detection current, which is smaller than the rated current, for detecting an abnormality in the light-emitting element; a voltage detection circuit which detects a voltage across both ends of the light-emitting element; and a control circuit which causes the step-down chopper circuit to stop outputting the current to the light-emitting element, when the voltage across both ends detected by the voltage detection circuit in the detection mode is lower than or equal to an abnormality detection threshold voltage which is set lower than the rated voltage at the time when the light-emitting element is turned ON.

Abstract: A light-emitting element lighting device includes: a step-down chopper circuit which outputs current to a light-emitting element; a current command circuit which selects between (i) light-emission mode for causing a light-emission current larger than a constant rated current, which flows to the light-emitting element when continuous light-emission is caused, to flow and (ii) detection mode for causing an abnormality detection current smaller than the rated current, to flow for detecting a light-emitting element abnormality; a voltage detection circuit which detects a both-end voltage of the light-emitting element; and a control circuit which causes the step-down chopper circuit to stop outputting the current to the light-emitting element, when the both-end voltage detected by the voltage detection unit in the detection mode is lower than or equal to an abnormality detection threshold voltage which is set lower than the rated voltage at a time when the light-emitting element is turned ON.

Abstract: In an automotive cowl louver support structure, vehicle-widthwise both sides of a cowl louver disposed between a windshield and a hood can be supported by lower portions of right and left rain gutters, and ornamental surfaces of the rain gutters can be continuous with a ornamental surface of the cowl louver. Engaged portions are provided to lower portions of the right and left rain gutters. Engagement portions configured to engage the respective engaged portions are provided to vehicle-widthwise both sides of the cowl louver. Further, the engagement portions of the cowl louver are engaged with the engaged portions of the right and left rain gutters.
