Abstract: An embodiment armrest assembly for a vehicle includes an armrest rotatably coupled to an armrest board and configured to be extended from the armrest board by rotating forward or to be housed in the armrest board by rotating and standing and a speed-reduction damper mechanism connecting the armrest and the armrest board and configured to make a rotational speed of the armrest uniform by reducing the rotational speed when the armrest rotates to be extended.

Abstract: An embodiment armrest assembly for a vehicle includes an armrest including a main body and a lid, an armrest board to which the armrest is rotatably coupled and in which the armrest is accommodated in an erect state, and a skirt coupled to a rear bezel housing of the lid and to the armrest board and correspondingly covering a rear space of the lid when the armrest is rotated forward, wherein the skirt has a panel shape and includes a hard material.

Abstract: Provided is a display data channel (DDC) communication module reading and storing extended display identification data (EDID) of a display device and providing the stored EDID to a host device. The DDC communication module includes: a serial electrically erasable and programmable read only memory (EEPFROM) in which the EDID is stored; a comparator outputting logic data indicating that the comparator is connected to the display device or the host device; and a controller reading and storing EDID, or providing EDID stored in the serial EEPROM to the host device, according to the logic data output from the comparator.

Abstract: Provided is a digital image transmission system in a high definition multimedia interface (HDMI) format or a digital visual interface (DVI) format. A transmission and reception reinforcement device of the digital image transmission system includes a transmitter, a receiver, and a power supply circuit. The power supply circuit includes a first power supply unit supplying power to the transmitter and a second power supply unit supplying power to the receiver. Power output terminals of the first and second power supply units are connected to each other. External-power supply voltages respectively input to the first and second power supply units are output to the power output terminals. When all of the external-power supply voltages input to the first and second power supply units are lower than a predetermined voltage, an internal-power supply voltage present in a communication line between the host device and the display device is output to the power output terminals.
