Abstract:
Disclosed herein are an apparatus and method for visible light communication using electrically switchable glass. The apparatus for visible light communication using the electrically switchable glass includes a reception unit for receiving a data signal, a control unit for generating current and voltage corresponding to the data signal and controlling the transmittance of the electrically switchable glass based on the current and the voltage, and a transmission unit for adjusting the brightness of visible light that passes through the glass based on the transmittance and performing visible light communication using the visible light that has passed through the glass.
Abstract:
An individual lighting control apparatus and method are disclosed herein. The individual lighting control apparatus includes a reception unit, a terminal connection unit, a sensor unit, and a lighting environment sensing and terminal state determination unit. The reception unit receives the location information of a corresponding individual illumination light. The terminal connection unit acquires the state information of a terminal corresponding to the location information of the illumination light. The sensor unit acquires the sensor information of the set surrounding area of the terminal. The lighting environment sensing and terminal state determination unit sets operation mode based on the state of the connection with the terminal, and then monitors the state of the terminal or the state of the set surrounding area of the terminal in accordance with the set operation mode. The individual illumination light is controlled by providing state change information to a lighting control scheduler.
Abstract:
Disclosed herein are an apparatus and method for controlling a lighting network. The apparatus for controlling lighting network includes a control device and a plurality of control gears. The control device generates and transfers commands to control lighting. The plurality of control gears receives the commands from the control device and control lighting. The control device assigns a right to use a lighting network to the control gears, and the control gears send information about a change in a lighting state or error details to the control device using the right to use a lighting network.
Abstract:
The present invention relates to an inter-vehicle communication apparatus and method using visible light communication. The inter-vehicle communication apparatus using visible light communication includes a spreading code application unit for applying a spreading code to transmission data desired to be transmitted, and a transmission unit for generating a transmission frame based on the transmission data to which the spreading code is applied, and transmitting the transmission frame via a lighting lamp of a vehicle. The transmission frame includes a preamble field required to synchronize the transmission frame, a data field required to transmit the transmission data, and a position field required to provide hopping information of the transmission data.
Abstract:
The present invention relates to a real-time movement path estimation apparatus using visible light communication. A server for performing communication with an agent for tracking a location of a client which is a target to be tracked includes an agent management unit for setting the agent and the client. A server communication unit receives management information of the agent at intervals of a preset monitoring period. A path prediction unit derives a predicted path for a movement path of the client, based on the location information of the client included in the management information and tracked by a location determination device including a visible light communication device or an image capturing device in the agent.
