Abstract: A harbor lighting control apparatus is provided, which includes a plurality of slaves to perform on control or off control, and dimming control with respect to a light emitting diode (LED) array light source mounted to a lighthouse when an on control signal or off control signal, and a dimming control signal are received, and to transmit a result of the control as acknowledge signals, and a master to transmit the on control signal or off control signal and the dimming control signal to all of the plurality of slaves by a broadcast scheme, to transmit the on control signal or off control signal and the dimming control signal to an individual slave by a unicast scheme, and to recognize operational states of the plurality of slaves by receiving the acknowledge signals from the plurality of slaves. Accordingly, stable and reliably control of the harbor lighting is enabled.

Abstract: Disclosed herein is a lighting apparatus. The lighting apparatus includes: a first light emitting unit including one or more main light sources radiating white light downward; one or more second light emitting units formed at the sides under the first light emitting unit and including one or more sub-light sources radiating color light that is mixed with the white light radiated from the first light emitting unit; and a light guide plate mixing the white light radiated from the main light sources and the color light radiated from the sub-light sources and radiating the mixed light downward. According to the embodiments, it is possible to remove non-uniformity of luminance of the lighting apparatus that can control color temperature by efficiently disposing main light sources radiating white light and sub-light sources radiating color light. Further, it is possible to increase efficiency of the lighting apparatus by radiating light, using all of the main light sources even at any color temperature.

Abstract: An apparatus and method for sharing television broadcasting are provided. The method includes, in a first portable terminal, connecting to a wireless network, and sending a TV broadcasting request to a TV module, for the first portable terminal to be granted a master function of switching a TV channel, receiving a password input request from the TV module, and transmitting a password to the TV module, in the first portable terminal, receiving the TV broadcasting from the TV module through the wireless network, and, in at least one or more additional portable terminals, receiving the TV broadcasting from the TV module through the wireless network, and sharing the TV broadcasting with the first portable terminal.

Abstract: A cordless telephone for making an emergency call upon sensing separation of a handset from a charger of a base unit. The handset is normally set in the charger in an idle state. A handset sensor detects separation of the base unit from the charger, and a user interface is used to input an emergency mode setting command and a phone number for an emergency call. A memory stores the input phone number for the emergency call, and a telephone answering device generates a voice message annunciating an emergency situation. When the handset is separated from the charger, a controller mutes a speaker, forcedly hooks off the base unit, reads the phone number for the emergency call from the memory, dials the read phone number, and sends the voice message. A microphone can also be enabled in order to transmit the sounds of the emergency situation to a called party.
