A method and device are provided for adjusting a focus bias of an objective lens of an optical pickup for an optical disc using a level of a tracking error signal. The level of the tracking error signal outputted when the optical disc is rotated and driven is detected for a predetermined period of time. An operation of adjusting the focus bias of the objective lens is carried out on the basis of the detected level of the tracking error signal. A focus bias adjustment value is set as an optimum focus bias value at a time when the detected level of the tracking error signal is maximized. In accordance with the method, a period of time for adjusting the focus bias is very short, on the order of “0” to several hundred milliseconds, in comparison with periods of time for adjusting the focus bias in conventional methods, such that the focus bias can be quickly adjusted. Moreover, the method moves the objective lens to an optimum focus point where the thickness of a substrate in the optical disc is thinner or thicker than the standard thickness (e.g., 0.6 mm in the case of a DVD (Digital Versatile Disc)), thereby enabling a normal playback operation.

The present invention relates to a composition for preventing or treating neurological diseases including an extract of Euphoria longan fruit, red sage and Gastrodia elata as an active ingredient. The composition of the present disclosure has a superior effect of inhibiting the activity of acetylcholinesterase (AChE), which hydrolyzes the neurotransmitter acetylcholine directly involved in impairment of cognitive function. In addition, the composition of the present disclosure is safe for the human body since the biologically safe extract of Euphoria longan fruit, red sage and Gastrodia elata is used as the active ingredient.

A broadcast receiver and method of providing a preferred channel thereof are disclosed. The present invention includes receiving a program of the preferred channel (52) set by a user among a plurality of broadcast channels, transforming an image of the received program of the preferred channel into a reduced image (54) and storing the reduced image per the preferred channel. Accordingly, when a turn-on mode of the broadcast receiver is switched to a turn-off mode (56) of the broadcast receiver, when a turn-off mode (56) of the broadcast receiver is switched to a turn-on mode of the broadcast receiver, or when a display of a preferred channel is requested in a turned-on mode, a per preferred channel reduced image is displayed as OSD (60) on a currently viewed image. So, a user is facilitated to recognize and select a program received on the preferred channel without blocking the currently viewed image.

The present invention is to protect a pen tip by covering the pen tip of a touch pen used to input data on a touch screen or a touch panel with a conductive or nonconductive cap. A stylus for a cellular phone according to an exemplary embodiment of the present invention includes: a pen tip for a touch pen including a connection groove into which a stick-type pen body is fitted and a void for restoring the shape of the pen tip by elastic force at the time of touching the touch screen; a thin-film type protective cap covering the pen tip; and a pointer of which one end is connected to the pen body and the other end is fitted into the connection groove of the pen tip and preventing the pen tip from being transformed due to excessive elastic force.

A method and device for determining the presence or absence of a disk and/or a disk size without using FG signals, are provided. The method includes placing a pickup at a first zone on the optical recording medium, the first zone located between an outer radius of a first recording medium type and an outer radius of a second recording medium type, where the outer radius of the second recording medium type is larger than the outer radius of the first recording medium type; detecting a reflected signal based on a returned beam from the first zone of the optical recording medium; and determining at least one of a size and an absence of the optical recording medium based on the detected reflected signal. Therefore, an FG sensor that is provided in a general disk device can be eliminated, thereby reducing the size and cost of a disk device.
