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.

Motion detection system

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.

Information presenting method, server, and information presenting system

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.

Light-emitting device and mobile object

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.
