Abstract:
An apparatus and method for rapidly controlling the disk rotation by detecting a high speed rotation and a reverse rotation of a disk. The disk driving apparatus for controlling rotation of a disk in a normal mode includes a spindle motor for driving the rotation of the disk by a spindle control signal and for generating a spindle driving voltage as the disk rotates, a servo control for generating the spindle control signal of the spindle motor by a servo control signal, a device for converting the spindle driving voltage into digital data, a device for storing a rotation range data table of the spindle driving voltage corresponding to ah abnormal rotation of the disk, and a controller for comparing and analyzing the converted digital data with the rotation range data table, sensing normal and abnormal states, and generating the servo control signal from the sensed results. Upon sensing an abnormal state the controller generates the servo control signal applying a reverse torque to a rotation direction of the spindle motor during a predetermined time, and sequentially performs a stop mode and a normal driving mode.
Abstract:
Provided is an unpowered and automatically flushing toilet seat, for a water tank, having detachable and waterproof functions. A loading lever rotates, for the descending movement of a toilet seat, and presses a loading member, thereby enabling enhancement of the transmission efficiency of the force and smooth operation. Since the loading member maintains the loaded state until a toilet paper time and flush control unit presses and releases the loading member, which has been moved and loaded by the pressing of the loading lever, a user can easily acquire time for discarding toilet paper.
Abstract:
A display apparatus, a remote controller and a method for controlling applied thereto are provided. The display apparatus receives direction information regarding an orientation of the remote controller from the remote controller, and selects an area to be controlled by the remote controller from among a first area and a second area of a screen according to the direction information received from the remote controller. As a result, user is enabled to control different areas on the screen by appropriately moving the remote controller between different orientations.
Abstract:
An optical disc drive, and a method of driving the optical disc drive are provided. Where the optical disc drive has a connectivity or a compatibility with a host that is incompatible with the optical disc drive, a file system and device information accepted by the host are provided. The host may have a compatibility with limited external medium devices and a specific command set for data exchange. The optical disc drive and the method of driving the optical disc drive may transmit compatible information to the host and select the specific command set accepted by the host, so that the optical disc drive is compatible with the host.

A second semiconductor fin may be provided on the second region of the substrate with the second semiconductor fin including a second trench therethrough, a second gate electrode may be provided in the second trench, and third and fourth source/drain regions may be provided in the second semiconductor fin with the second gate electrode being between the third and fourth source/drain regions.
Abstract:
The power supply includes: an electromagnetic interference filter including a first filter which has a pair of electromagnetically coupled cores having at least two leg parts, first and second bobbins each having a tube-shaped body part having a penetration hole into which each of the leg parts is inserted and having a winding region defined as the circumference of the outer peripheral surface of the body part, and first and second coils respectively wound around the first and second bobbins to remove common mode electromagnetic interference included in power transmitted from a power line, the electromagnetic interference filter removing differential mode electromagnetic interference due to leakage inductance formed due to the leakage of magnetic flux flowing through the cores; a power factor corrector correcting a power factor of the power where the electromagnetic interference is removed; and a power converter switching the power-factor-corrected power into a driving power having a predetermined voltage level.
Abstract:
A display apparatus and a method for displaying a menu are provided. The display apparatus displays a content image on a first area of the entire screen area at a specific screen ratio and displays a menu comprising a plurality of pages on a second area corresponding to an area excluding the first area where the content image is displayed. Accordingly, the display apparatus may display a menu without blocking the content image or deteriorating quality of the content image.
Abstract:
Disclosed herein are an apparatus and method for detecting the survival status of a living thing. The apparatus for detecting the survival status of a living thing includes a tilt sensor, a determination unit, and a communication unit. The tilt sensor is attached to a target living thing, and detects minute vibrations generated by the motion of the target living thing. The determination unit determines the survival status of the target living thing for a preset update period based on the minute vibrations. The communication unit sends an update packet including determination results of the determination unit to an outside.
Abstract:
An image display device includes front and rear covers which surround a display panel and a plurality of connection members connected to the display panel and connected to each of the covers. Thereby, the display panel has a bezel part having a narrow width, and the front and rear covers are easily fixed to each other.
Abstract:
A decoder, a memory system, and a physical position converting method thereof may detect whether an address count of an input address is equal to or greater than a predetermined value. A physical position of a semiconductor memory device corresponding to the input address may be converted if the address count is equal to or greater than the predetermined value.
