Abstract: A ring-type wearable device is disclosed. The disclosed ring-type wearable device comprises: an outer ring member; an inner ring member separably inserted into the outer ring member; a sensor unit disposed in the outer ring member; and a control unit disposed in the outer ring member so as to be electrically connected to the sensor unit, wherein the sensor unit can maintain constant sensitivity in correspondence to the thickness of the inner ring member.

Abstract: A tilt prop aircraft is provided, including a first longeron and a second longeron capable of tilting relatively to each other, a tilt actuator disposed on the second longeron, a first power transmission member rotated by the tilt actuator, a second power transmission member fixed to the first longeron and coupled to the first power transmission member to transmit a rotational movement of the first power transmission member by turning 90 degrees in different planes, a crank fixed to the second longeron and extending through a slot in the first longeron and protruding inwardly from the first longeron, and a connecting rod connected to the crank so as to be relatively rotatable to the crank, and connected to the pitch control rod.

Abstract: A lighting device includes a light guide plate configured to guide and diffuse a light from a light source, and a garnish body including a lighting area to which the diffused light is radiated, wherein the light guide plate is disposed at a predetermined angle with respect to the garnish body.

Abstract: A communication system configured to perform an address translation and a method of translating an address of the communication system are provided. The communication system configured to transceive a packet through a network includes a modem circuit configured to modulate the packet into a transmission signal to be transmitted to the network and demodulate a receiving signal from the network into the packet, and an address translation circuit configured to translate a network address of the packet, wherein the address translation circuit includes an embedded memory configured to receive a header of the packet from an external memory in which the packet is stored and store the header, a first translator configured to translate a format of the header, and a second translator configured to translate an address included in the header.

Abstract: A bus traffic control apparatus includes a sizing block, a traffic request controller and a bus master engine. The sizing block is configured to determine a data transmitting size of a bus master based on bus traffic information. The traffic request controller is configured to control transmission of data from the bus master based on the data, a destination of the data, the data transmitting size. The bus master engine is configured to transmit the data to the destination in the data transmitting size based on the data, the destination of the data, the data transmitting size and a request received from the traffic request controller.
