Abstract: Provided is a lighting system that illuminates an object with illumination light. The lighting system includes a radio frequency (RF) tag and a lighting device. The RF tag is directly attached to the object or assigned to the object and stores attribute information on the object. The lighting device illuminates the object with the illumination light and includes a light source, a communication circuit, and a controller. The light source emits the illumination light. The communication circuit includes an RF tag reader that wirelessly reads the attribute information stored in the RF tag. The controller controls at least one of dimming, a color, and an emission time of the illumination light emitted by the light source, based on the attribute information read from the RF tag by the RF tag reader.

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: Disclosed herein is a receiver including a receiver circuit, a control circuit, and a wireless communications circuit. The control circuit retrieves identification information and content information from a plurality of transmitters based on an output of the receiver circuit. The control circuit retrieves, when having failed to retrieve content information from the plurality of transmitters, identification information from at least two of the plurality of transmitters, identifies one of the at least two of the plurality of transmitters as a target transmitter in association with the retrieved identification information, and also identifies another one the at least two of the plurality of transmitters as a non-target transmitter in association with the retrieved identification information. The wireless communications circuit transmits the control signal to allow the target transmitter to transmit the second optical signal and cause the non-target transmitter not to transmit the second optical signal.

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.
