Abstract:
The present invention relates to a method for processing call traffic in an ATM Switch Block (ASB) in a CDMA 1x system. The CDMA 1x system comprises a Base Transceiver System (BTS), which comprises an OA, a High-speed Transfer and Selector Block (HTSB), an ATM Switch Block (ASB), an ATM Traffic Block (ATB) and a MMCA, and a Base Transceiver System (BTS), which is coupled to a Call Control Processor (CCP). When a request for call setup is transferred from the BTS to the CCP, a traffic path between the OA and the MMCA is set up through performing the claimed method. The present invention removes unnecessary traffic paths so as to utilize system resources efficiently while optimizing system performance.
Abstract:
The method of producing 4-fluoroethylene carbonate (FEC), in which ethylene carbonate (EC) reacts with a mixture of fluorine and nitrogen gases, includes feeding a mixture gas of fluorine gas and nitrogen gas into a reactor having ethylene carbonate charged therein, so as to react the ethylene carbonate with the mixture gas of the fluorine gas and the nitrogen gas. The mixture gas fed in the reactor is regulated to have a desired bubble size while passing through a gas bubble regulating column, in which a packing for a packed column is packed. In the method, EC directly reacts with F2/N2 mixture gas to produce FEC, thus a purification process is simple and it is possible to produce FEC at high conversion efficiency and selectivity.

Abstract:
In a semiconductor device and a method of manufacturing the semiconductor device, a plug and a channel structure are formed. The plug fills an opening and the channel structure extends upwardly from the plug. The channel structure has a substantially vertical sidewall. The opening is formed through an insulation structure located on a substrate. The plug and the channel structure comprise a material in a single crystalline state that is changed from an amorphous state by an irradiation of a laser beam. The channel structure is doped with impurities such as boron, phosphorus or arsenic.

An inspecting apparatus for semiconductor devices including: a match plate; a contact module combined with the match plate, and the match plate including a radiation unit radiating heat from the semiconductor devices to the outside, and a test unit contacting leads of the semiconductor; an insert module installed on a bottom of the contact module, and having a semiconductor device accommodator to accommodate the semiconductor device; and an auxiliary radiation member installed on a bottom of the insert module, and radiating the heat from the semiconductor device to the outside. Accordingly, the inspecting apparatus for semiconductor device according to the present invention performs testing at a constant temperature regardless of heat from the semiconductors by radiating the heat from the semiconductors immediately and efficiently, thereby producing more accurate test results. Accurate testing improves productivity and saves expense by removing faulty test results caused by identifying a qualified semiconductor as a defective semiconductor due to heat radiated from the semiconductor device.

The system includes: a sensor unit to sense a backward speed, presence of a backward object, and the operating state of the brake pedal and the accelerator pedal of an automobile when backward-travelling; a telematics system unit to output a control signal, when a distance between the automobile and the object is within a pre-set range in response to the signal from the sensor unit, such that the backward-travelling is automatically interrupted to thereby prevent collision with the object; and a accelerator pedal control unit and a brake pedal control unit to automatically control the operation of the accelerator pedal and the brake pedal to thereby interrupt the backward-travelling in response to the control signal outputted from the telematics system unit.
Abstract:
Disclosed is a method for crystallizing a single crystalline Si film on an amorphous substrate, such as a glass substrate or a plastic substrate. The method includes the steps of selectively irradiating the laser beam onto a pixel section TFT forming region and a peripheral circuit TFT forming region of the amorphous silicon film through primary and secondary laser irradiation processes, thereby forming a poly-silicon film and irradiating the laser beam onto one of grains formed in the poly-silicon film through a third laser irradiation process, thereby forming a single crystalline silicon region having a desired size on a predetermined portion of the amorphous silicon film. The amorphous silicon film is locally crystallized into the single crystalline silicon film so that characteristics of TFTs for the pixel section and the peripheral circuit are improved while ensuring high uniformity.

The method may include coupling a human to a motor and monitoring the gait of the human while the human is walking to produce a signal indicative of the gait of the human. The method may also include varying the operation of the motor based on the signal so as to assist the human in attaining a predetermined gait pattern.
Abstract:
A method, system and apparatus for restricting, within a specific area, the photographing function of a camera mounted in a mobile terminal. A control signal is transmitted to a mobile terminal within a photograph-prohibited area and the mobile terminal disables the camera. Upon leaving the photograph-prohibited area, the camera is enabled.
