Provided is an electronic apparatus comprising a main body and a kit connected to the main body, wherein the main body comprises a battery, a first motor, an electric wire connected to the battery and a first controller connected to the electric wire, wherein the kit comprises a second motor supplied with power through the electric wire and a second controller connected to the electric wire, wherein the first controller comprises a first signal generator configured to generate a signal to be transmitted to the kit and a first modulator configured to modulate the signal generated by the first signal generator, and wherein the signal modulated by the first modulator is transmitted to the second controller through the electric wire.

Electronic device performing powerline communication and operation method thereof

Disclosed herein are a dual-mode device operating in a visible light communications mode and a wireless network communications mode, and a method performed by the device. The visible light communications device includes a wireless network communications unit including a fixed identifier and performing communications based on a wireless protocol, a visible light transmitting unit transmitting the fixed identifier using a visible light communications protocol, and a controller (control unit) controlling the visible light transmitting unit so that it selectively transmits the fixed identifier using the visible light communications protocol depending on whether the wireless network communications unit is connected to a wireless network.

Device implementing visible light communications and wireless network communications in dual mode and method of implementing thereof

A visible-light receiver and a visible-light communication system including the visible-light receiver may improve an accuracy of light reception. The visible-light receiver may include a housing having a first opening defined on a top face thereof; a lens module provided inside the housing that receives light or a visible-light signal and converts the light into an electric or electrical signal, wherein the light may be emitted from a visible-light emitter and passes through the first opening and to the lens module; a data processing module or data processor assembly provided within the housing that receives the electric signal from the lens module and converts the electric signal into data; and a cap or hollow tube provided on a top face of the housing so as to extend around the first opening and protrude upwardly, wherein the cap may have second and third openings defined in lower and upper portions thereof, respectively.
