Abstract:
The present invention relates to a system and a method for wirelessly transmitting and receiving power and data using mutual resonance. In an aspect, a reception node using mutual resonance includes: a target resonator receiving power through the mutual resonance with a source resonator; a controller waking up by the received power and determining the time of the wake-up as synchronous time with other nodes to produce data packet; and a sensing part waking up by the received power to sense information.
Abstract:
The present invention relates to a backlight unit and a display device using the same which comprises light control units which are disposed on a side of a light guide plate and have different reflectance from each other. Light efficiency can be improved and occurrence of illuminating parts can be reduced by installing the light control units having different reflectance.
Abstract:
Provided is a wireless charging device capable of transmitting power wirelessly. The wireless charging device includes: a charging unit which transmits power to a mobile device; a system unit which supplies power to the charging unit through a connection unit; and the connection unit which connects the charging unit to the system unit while adjusting the position and the angle of the charging unit.
Abstract:
PURPOSE: A dust collecting structure for an air-conditioning type electric apparatus and the electric apparatus including the same are provided to prevent the malfunction of the electric apparatus from being occurred by dust. CONSTITUTION: A dust collecting structure(100) for an air-conditioning type electric apparatus includes a plurality of first vortex generating members(110) and a plurality of second vortex generating members(120). The first vortex generating members are parallelly installed in a case(10) and form a plurality of inlets(11). The second vortex generating members are installed at the inner part from the inlets and are spaced apart from each other. The first vortex generating members are protruded from the case toward the inner part of the case.
Abstract:
PURPOSE: A mobile message reception apparatus and method thereof are provided to select an SMS(Short Message Service) push method according to user mind. CONSTITUTION: When a mobile message arrival alarm is received from a push server, a push client(31) informs the arrival of the mobile message to a client(32). In case MM client is terminated, the push client activates the MM client. In case the push client is completed, an SMS(Short Message Service) client(33) receives the arrival alarm from the push server through the SMS message.
Abstract:
PURPOSE: A non-volatile memory device is provided to improve reliability by largely forming the pitch of a circuit word line pattern than the pitch of a cell word line pattern which is adjacent. CONSTITUTION: A plurality of variable resistor elements is formed in the top of a substrate. A plurality of bit lines(BL) is extended to a first direction on a plurality of variable resistor elements and is separately formed to a first pitch(P1). A plurality of cell word lines is extended to a second direction on a plurality of bit lines and is separately formed to a second pitch(P2). A plurality of circuit word lines is extended to the first direction on a plurality of bit lines is separately formed to a third pitch(P3). The third pitch of a plurality of circuit word lines is bigger than the first pitch of a plurality of bit lines.
