Abstract:
The present invention relates to a bio-inspired distributed wireless resource allocation, and a method of solving a conflict of a firing phase allocation in the bio-inspired distributed wireless resource allocation includes (a) selecting a reference firing phase having a preset degree of allocation-available space, on the basis of firing phase allocation information within a received firing message, when a newly-entered node attempts the firing phase allocation, (b) calculating changeable positions of the reference firing phase and a succeeding firing phase of the reference firing phase under assumption set based on the firing phase allocation information, and (c) setting a space between the changeable positions as an allocation-available range and allowing the newly-entered node to be allocated with an arbitrary firing phase within the allocation-available range.
Abstract:
There is provided a method for preparing an acrylic copolymer resin for an optical film includes: suspension-polymerizing an acrylic monomer containing a benzene ring, an alkyl(meth)acrylate monomer, and a (meth)acrylic acid monomer to prepare a copolymer; and thermally treating the copolymer at a temperature ranging from 240° C. to 300° C. As the method for preparing an acrylic copolymer of the present invention, a resin having an effectively lowered CTE can be manufactured by inducing the formation of a glutaric anhydride structure by using suspension polymerization that facilitates adjustment of the molecular weight of a resin.
Abstract:
A voltage stabilizer circuit for alternately or simultaneously stabilizing first and second generated voltages includes shared capacitor connected between the first and second generated voltages. The voltage stabilizer circuit may further include first and second switches for alternately connecting the first and second electrode of the shared capacitor to a ground. The alternation of the stabilized first and second voltages output by the voltage stabilizer circuit can be synchronized with a pixel polarity inversion mode signal output by the internal driver circuit of an LCD display.

Abstract:
An apparatus and method perform Transmit Power Control and Dynamic Frequency Selection (TPC/DFS) during a movement of a Base Station (BS). A network environment around the mobile BS is modeled. Based on the modeling result, a TPC/DFS operation scheme that is most suitable to the mobile BS is selected.
Abstract:
Disclosed herein is an inertial sensor. The inertial sensor includes a sensing unit and a driving-mass-position initialization module. The sensing unit includes a driving mass, a flexible board unit which displaceably supports the driving mass, and a support which supports the flexible board unit to allow the driving mass to move in a suspended state. The flexible board unit has driving electrodes which move the driving mass, and sensing electrodes which sense the movement of the driving mass. The driving-mass-position initialization module includes a position initialization member which reciprocates to initialize the position of the driving mass, and a coil unit which surrounds the position initialization member. An initialization-member-receiving depression is formed in the driving mass. The shape of the initialization-member-receiving depression corresponds to that of the position initialization member.
