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:

Abstract:
A lighting control system includes: lighting apparatuses; a controller; an image sensor capturing an image of an irradiation surface irradiated by the lighting apparatuses; and a display. The controller includes: a calculator which performs calculation of a position of one of the lighting apparatuses, on a basis of a luminance level in an image obtained by capturing the image of the irradiation surface by the image sensor in a state in which only the one of the lighting apparatuses is turned on or off; an associator which, every time the calculator performs the calculation of a position of one of the lighting apparatuses which is turned on or off, associates the identification information item set in advance to the one of the lighting apparatuses, with a position information item indicating the position of the one of the lighting apparatuses; and a generator that generates a map.
Abstract:
A lighting apparatus includes a control circuit configured to control a power supply circuit such that a measurement value of an output current measured by a current measuring device approaches a target value. The control circuit is configured to execute a control mode alternatively selected from the plurality of control modes to control the power supply circuit. The plurality of control modes of the control circuit includes at least a first control mode and a second control mode. The first control mode is a control mode of adjusting the target value in accordance with a first direct-current voltage. The second control mode is a control mode which includes adjusting the target value regardless of the first direct-current voltage.
Abstract:
A mobile-related communication system includes a first information transmitting body including a first wireless communication unit, a first control unit, and a first optical communication unit, and a second information transmitting body including a second wireless communication unit, a second control unit, and a second optical communication unit. The first control unit causes the first optical communication unit to acquire ID information of the second information transmitting body and an encryption key via the second optical communication unit and causes the first wireless communication unit to wirelessly transmit to the second information transmitting body a provision request for transmitting body-related information related to the second information transmitting body. The second control unit causes the encrypted transmitting body-related information using the encryption key to be wirelessly transmitted on the basis of the provision request, and the first control unit decrypts the received transmitting body-related information using the encryption key.
Abstract:
A lighting control device includes: a candidate color selector; a candidate color adjuster; and a color controller. The candidate color selector selects, in accordance with the indication obtained by the indication obtainer, a plurality of candidate colors to be used for color control of lighting devices, from an image obtained by an image obtainer. The candidate color adjuster makes automatic-mode adjustment which is processing for determining colors reproducible by the lighting devices, in accordance with predetermined indexes and based on the plurality of candidate colors selected by the candidate color selector. The color controller causes the lighting devices to each emit illumination light having the color determined by the candidate color adjuster, by controlling the lighting devices.
Abstract:
A lighting apparatus that irradiates light on a vehicle is provided. The lighting apparatus includes: a first light source that emits light for illuminating a predetermined area; a memory that stores location information indicating a location of the lighting apparatus; a second light source that outputs, to the predetermined area, a light signal indicating the location information; and a first controller that controls the first light source and the second light source, and modulates the light signal output by the second light source, in accordance with the location information stored in the memory.
Abstract:
An in-vehicle lighting device for alerting a driver driving a vehicle to an obstacle present in a vicinity of the vehicle, which obstructs driving of the vehicle. The in-vehicle lighting device includes: a light emitter that is installed in an interior side of a pillar in a front part of the vehicle and that emits light of different chromatic colors; a controller connected to the light emitter; and a detector that is connected to the controller and detects the obstacle present in the vicinity of the vehicle. When the detector detects the obstacle present in the vicinity of the vehicle, the controller causes the light emitter to emit light having a color according to a characteristic of the obstacle detected.
Abstract:
An illumination control apparatus including a controller which: in switching a first lighting mode to a second lighting mode when a combination of results of detections by occupancy sensors changes, compares a first priority level pre-assigned to the first lighting mode and a second priority level pre-assigned to the second lighting mode; if the second priority level is lower than the first priority level, maintains the first lighting mode for a predetermined amount of wait time from a moment when the combination of the results of the detections changes, and subsequently switches the first lighting mode to the second lighting mode; and if the second priority level is higher than the first priority level, switches the first lighting mode to the second lighting mode at the moment when the combination of the results of the detections changes.
