Provided are a method of preparing a large-area, three-dimensional graphene transparent electrode using an electrospray deposition method and a large-area, three-dimensional graphene transparent electrode prepared therefrom. More particularly, the present invention is related to a method of preparing a large-area, three-dimensional graphene transparent electrode using an electrospray deposition method, which may easily prepare a large-area graphene transparent electrode having high transparency and conductivity through an electrospray process and may obtain effects, which may not be realized in a two-dimensional transparent electrode prepared by a typical method such as CVD, due to a three-dimensional stack structure in which graphene is arranged perpendicular to a substrate, and a large-area, three-dimensional graphene transparent electrode prepared therefrom.

A method and apparatus for controlling transmission of an RPC channel during a handoff in a mobile communication system. Only one AN is selected among a plurality of ANs to transmit reverse power control information to an AT. For this purpose, a Forward Link Selection message received at an AN from an RNC can be used. Alternatively, a DRC cover received at an AN from an AT can be used. The DRC cover indicates at least one of ANs excluding an AN having the worst channel condition for the AT.

Embodiments of the present invention may provide a module for detecting a vehicle crash. The module includes a housing mounted to a vehicular frame member at one end portion thereof. The module includes first and second rods housed in the housing. The first rod is contacted to the frame member at one end thereof through the one end portion of the housing. The second rod is contacted to the opposite end of the first rod and being disposed between the first rod and the opposite end portion of the housing. The module includes first and second sensors mounted to the first and second rods respectively for detecting a crash by sequentially measuring stress wave caused by the crash. The first sensor detects a stress wave propagating through the first rod and outputting a signal. The second sensor detects a stress wave propagating through the second rod and outputting a signal. The module includes a biasing member disposed between the second rod and the opposite end portion of the housing for biasing the first and second rods toward the frame member. A magnitude of impedance of the first rod is larger than that of the second rod and the magnitude of impedance of the second rod is larger than that of the biasing member. The module can remarkably reduce the elapsed time required for detecting a crash by measuring a stress wave, which propagates very rapidly through a vehicular frame member.

A mask and method of manufacturing is disclosed. The mask may include a transparent quartz substrate having light-transmitting regions and light-shielding regions, a light-control layer formed on the substrate excluding a portion corresponding to a light-transmitting region of an edge portion, and a light-shielding layer formed on the light-control layer of an light-shielding region. The method may include the steps of preparing a quartz substrate, forming a light-control layer on the quartz substrate, forming a light-shielding layer on the light-shielding region of the light-control layer, and selectively etching the light-control layer corresponding to light-transmitting regions of an edge portion of the substrate.

The present invention may provide an airbag system for an automobile and a method of operating the same. The airbag system comprises the following: sensors mounted on a frame member of a the vehicle frame for detecting a crash by sequentially measuring stress wave cause by the crash; an electronic control unit for outputting an actuation signal based on outputs from the sensors; an inflator for generating a gas in response to the actuation signal; and an airbag operatively coupled to the inflator and being deployed by supply of the gas generated from the inflator. The sensors are mounted on the frame member at predetermined intervals in a path, along which the stress waves propagate through the frame member. The electronic control unit outputs the actuation signal when each output from each sensor exceeds a predetermined threshold. The airbag system can remarkably reduce the time required for detecting a crash by measuring the stress waves, which propagate very rapidly through the vehicle frame, thereby deploying the airbag in a timely manner.

Disclosed is an apparatus for performing power control on a reverse channel quality indicator channel (CQICH) received from a mobile station by a base station in a mobile communication system including the base station for transmitting a power control bit for power control on reverse channels and the mobile station for controlling transmission power of the reverse channels according to the power control bit. An erasure detector determines whether to perform an erasure process by measuring reception power of the reverse channel quality indicator channel. An erasure rate calculator accumulates the erasure-determined result for N slots and calculates an erasure rate for the N slots. A control bit generator determines a ratio control bit to be transmitted to the mobile station according to the erasure rate, to issue a command to increase or decrease a CQICH traffic-to-pilot ratio.
