Abstract: An electronic device includes: a transmission unit configured to transmit to a device management server, position information indicating a position where the electronic device is installed, unique information uniquely assigned to the electronic device, and setting information set to the electronic device; a first reception unit configured to receive from the device management server, setting information set to the electronic device, based on the position information and the unique information; and a control unit configured to perform a setting of the electronic device based on the received setting information.

Abstract: A display system includes a display control unit configured to display content based on a position of a vehicle along with identification information including information for identifying at least one of a time at which the content has been displayed and a position at which the content has been displayed on one or more display units on the vehicle. The display system further includes an acquisition unit configured to acquire at least one of the time at which the content has been displayed and the position at which the content has been displayed from the identification information acquired by a terminal device after the identification information displayed on the display unit has been acquired using a camera of the terminal device.

Abstract: A light source device includes a laser source unit, a rotating body including a phosphor layer and a reflective diffusion plate, and an optical path forming member that divides the emitted light of the laser source unit into a first laser beam and a second laser beam, irradiates the reflective diffusion plate with the first laser beam, and irradiates the phosphor layer with the second laser beam. The optical path forming member includes a first reflection plate with a through-hole and a first collimator lens. The first laser beam passes through the through-hole and the first collimator lens in that order and enters the reflective diffusion plate, and the diffused light from the reflective diffusion plate passes through the first collimator lens and enters the first reflection plate.

Abstract: A delivery server delivering first content to a plurality of information processing terminals includes: an acquisition unit configured to acquire response information indicating a response to the first content from the plurality of information processing terminals; a generation unit configured to generate reaction information for reflecting the response in the first content on the basis of the response information; and a delivery unit configured to deliver the reaction information or second content in which the reaction information is reflected in the first content to the plurality of information processing terminals. The response information includes information indicating a reproduction time of target content to which the response has been made in the first content and a response target to which the response has been made in the target content.
