Abstract:
A method and apparatus for measuring target gas concentrations in an atmosphere. The method and apparatus emit in the atmosphere a laser beam tuned to a molecular absorption line of a target gas, receive a reflected signal affected by gas absorption of the target gas in the atmosphere, divide and direct the received signal into a first optical path and a second optical path including in one of the paths a correlation gas cell filled with a predetermined concentration of the target gas, detect transmitted signals through the first optical path and the second optical path, and calculate a target gas concentration by comparing a first signal transmitted through the first optical path to a second signal transmitted through the second optical path. The apparatus includes a laser source tunable to a specific molecular absorption line of a target gas and configured to emit in the atmosphere a laser beam having a spectral bandwidth greater than a full width of the molecular absorption line of the target gas, a receiver configured to receive a reflected signal affected by gas absorption of the target gas in the atmosphere, and at least one detector configured to detect transmitted signals through the first optical path and the second optical path.

Abstract:
A method of providing a dynamic content service using an analysis of a user's response, the method including: monitoring the response of the user watching and/or listening to first content; analyzing preference information with respect to one or more scenes included in the first content, based on the monitored user's response; transmitting, to an external server, metadata of the analyzed preference information; receiving, from the external server, second content generated based on the metadata of the analyzed preference information; and outputting the received second content onto a screen.
Abstract:
A method of controlling a vehicle navigation apparatus included in a vehicle, and which includes displaying road guidance information on a touch screen display of the vehicle navigation apparatus and including a set travel route from a current position of a vehicle to a destination, determining, via a controller, whether a particular road displayed on the road guidance information has been drawn on, said particular road corresponding to a road that is different than a road included in the set travel route from the current position of the vehicle to the destination, and setting, via the controller, a road matched to the particular road that has been drawn on as a detour.
Abstract:
The present invention relates to aromatic polyether resins crosslinked with amic acid or imide side chain, and more particularly, to the aromatic polyether resin crosslinked by amic acid or imide side chain, which is produced by heat curing of amic acid, wherein introduction of imide groups to the basic backbone provides excellent chemical resistance as well as heat resistance and improves surface roughness when coated as a thin film so that it can be suitable for films and flexible display plate substrate.
Abstract:
A sense amplifier includes a reference signal providing unit and an internal sense amplification unit. The reference signal providing unit provides a reference bit line signal in response to a reference control signal. The internal sense amplification unit receives the reference bit line signal and data signals that correspond to the data. The received signals are provided through bit lines connected to the memory cell array. The internal sense amplification unit senses the received reference bit line signal and the data signals and amplifies the sensed signals. The sense amplifier senses data stored in memory cells connected to dummy bit lines of the outmost memory cell array of a semiconductor memory device such that the memory cells that are not used can be used. Accordingly, the design area and cost of the semiconductor memory device can be reduced.
Abstract:
The present invention relates to a multiple differential demodulator using a weighting value. The multiple differential demodulator according to the present invention includes a weighting value generator for integrating a real part and an imaginary part of a value acquired by multiplying one of a plurality of differentiated reception signals by a conjugated value of a differentiated PN code signal corresponding to a preset symbol, and determining the greater of the integrated real and integrated imaginary parts to apply a predetermined weighting value to the greater value, where the PN code signal is differentiated in the same fashion as the differentiated reception signals.
