Abstract:
A lower unit for a glass polishing system includes a support installed to a rotatable turntable, and a carrier having a supporting part for supporting a glass to be polished, and a placing part formed in a surface opposite to the supporting part and fixed and placed to the support.
Abstract:
Disclosed are an apparatus and a method for monitoring a glass plate polishing state. The apparatus may include a location measuring unit for measuring a location on a glass plate being polished by a polishing machine, a current measuring unit for measuring an electric current flowing into the polishing machine, a memory unit for storing a reference value of the electric current flowing into the polishing machine for each polishing location of the glass plate, and a control unit for determining whether a polishing state is faulty, by comparing a value of the electric current measured by the current measuring unit for each polishing location measured by the location measuring unit with a corresponding reference value of the electric current stored in the memory unit for each polishing location.

Abstract:
A mounting device for attaching an object to a supporting structure includes a first member including at least one first magnet and a projection, the first member configured to be attached to a supporting structure, a second member including at least one second magnet and a recess to receive the projection, the at least one second magnet configured to be attracted to the at least one first magnet, and an electromagnet selectively operable to provide magnetic force to couple the first and second members together. A method of mounting an electronic display to a supporting structure also is disclosed.
Abstract:
An apparatus and method to decrease bit rate through direct control of video compression parameters when compressing a video. The video compressing apparatus may use a Region of Interest (ROI)-dependent compression parameter and may include a ROI estimating part, a parameter allocating part, and a compression part. The ROI estimating part may estimate the ROI of an input video. The parameter allocating part may allocate a compression parameter to each region of the input video based on the estimated ROI information. The compression part may compress the input video by applying the parameter allocated to each region. A higher compression rate may be achieved by allocating a higher bit rate to the ROI and a lower bit rate to non-ROI regions.
Abstract:
An apparatus including a viewing screen supported by a display supporting surface, including a level device configured to indicate that an edge of the viewing screen is substantially level. The height of the viewing screen from the floor may be adjusted using a removable apparatus which may be disconnected from the viewing screen after the viewing screen is leveled.
Abstract:
The present invention relates to a new use of lignan-type compounds or an extract of nutmeg or aril of nutmeg comprising the same. More particularly, the present invention relates to a composition for skin whitening comprising a lignan-type compound or an extract of nutmeg or aril of nutmeg comprising the same. Because the lignan compound represented by Chemical Formulas 1 to 3 or the extract of nutmeg or aril of nutmeg has superior skin whitening activity by inhibiting melanin production and tyrosinase activity, it can be used for the preparation of a cosmetic composition, food composition or pharmaceutical composition for skin whitening.
