Abstract: Disclosed is a method, apparatus, and medium for estimating a pose of a moving robot using a particle filter. A method for estimating a pose of a moving robot using a particle filter according to an embodiment of the invention includes a detecting a change in pose of the mobile robot and calculating a pose of the current particle by applying the detected change in pose to the previous particle, predicting the probability of the pose of the current particle and obtaining a weight of the current particle on the basis of range data obtained by a sensor and map information, resampling the current particle on the basis of the weight, and adjusting the weight in consideration of an error of the sensor.

Abstract: In forming a pattern on a substrate with reduced pattern error using a mold having an area smaller than an area of the substrate, a first resin pattern is formed on at least a first of a plurality of regions of an etching object layer by imprinting resin applied to the etching object layer using a first mold The etching object layer is then etched using the first resin pattern as an etching mask. A second resin pattern is formed on at least a second of the plurality of regions by imprinting resin applied to the etching object layer using a second mold. The etching object layer is again etched using the second resin pattern as an etching mask.

Abstract: Provided are a method and apparatus for encoding and decoding an audio signal. According to the present application, a signal of a high frequency band above a preset frequency band is adaptively encoded or decoded in the time domain or in the frequency domain by using a signal of a low frequency band below the preset frequency band. As such, the sound quality of a high frequency signal is not deteriorate even when an audio signal is encoded or decoded by using a small number of bits and thus coding efficiency may be maximized.

Abstract: A method for retransmitting data when data transmission/reception has failed in a wireless LAN system using visible light communication. A mobile node searches a received frame for a fast feedback slot allocated for retransmission information when momentary data transmission/reception failure has occurred. One mini-slot from among the plurality of mini-slots is selected from the fast feedback slot. The mobile node transmits a fast feedback message, including information for retransmission, to an access point by using the selected mini-slot.

Abstract: A transmit antenna switching apparatus and method in a MIMO system are provided. The transmit antenna switching method includes determining modulation orders of users by using reception strengths of user signals with respect to each antenna; summing the determined modulation orders for each antenna; and determining an antenna having the greatest sum of the modulation orders as a transmit antenna. Accordingly, downlink performance can be remarkably improved by transmitting downlink frames through an optimal transmit antenna in accordance with channel environment.

Abstract: Provided is a complementary metal oxide semiconductor (CMOS) image sensor. The CMOS image sensor includes a pixel array unit having a matrix-type array of unit pixels, each unit pixel including a charge transfer element transferring charge collected in a photoelectric conversion element to a charge detection element. The charge transfer element also receives a boosted voltage signal higher than an external power voltage.

Abstract: A gain-clamped semiconductor optical amplifier having a horizontal lasing structure in which an oscillation direction of a laser is different from an amplification direction of a signal, and a method for manufacturing the gain-clamped semiconductor optical amplifier. The gain-clamped semiconductor optical amplifier includes a gain layer for amplifying an optical signal. A Bragg lattice layer is formed on both sides of the gain layer along a longitudinal direction of the gain layer for enabling light having a corresponding wavelength to resonate in a direction vertical to the longitudinal direction of the gain layer. A passive light waveguide restrains light resonating between lattices of the Bragg lattice layer. An electrode supplies current to the gain layer, and a current-blocking layer prevents current from flowing to an area other than the gain layer.

Abstract: A parallel multiplier by a skip array and a modified Wallace tree utilizes a modified Booth's encoder for encoding a multiplier according to a modified Booth's algorithm, a skip array for partial products, a modified wallace tree for adding binary bits, and a hybrid prefix adder for adding the final two lines. Fast multiplication of 0 (log n) is continuously performed without a standby state of a carry output and the regularity of the arrangement of the parallel multiplier is improved so that its chip area and manufacturing cost are reduced.
