Method and apparatus for detecting abnormal channel of microphone array detection and generating compensation signal are provided. A method includes receiving multi-channel sound source signals from a microphone array, synchronizing the multi-channel sound source signals based on spatial information of the microphone array, and detecting an abnormal channel of the microphone array by inputting the synchronized sound source signals and first conditional information to a neural network model configured to perform an inverse operation. The method further includes generating a compensation signal corresponding to an abnormal channel using a neural network model in response to an abnormal channel being detected.

Disclosed are a system and a method for transceiving data in an audio frequency band. The system includes a data input unit to input data for acoustic communication into an audio signal, a transmitting unit to transmit the audio signal including the data in the audio frequency band, and a receiving unit that receives the audio signal including the data and performs synchronization of the audio signal through a matched filtering using a matched filter in order to extract the data according to predetermined extraction processing. The data to be transmitted are added to an audio signal and the audio signal is transmitted in the audio frequency band, so that the data for the acoustic communication are effectively transmitted to the recipient in the audio frequency band.

System and method for data reception and transmission in audible frequency band

Provided is a synchronization system and method for acoustic communication in audible frequency range, and an apparatus applied thereto. The synchronization system for acoustic communication in audible frequency range is configured to prevent deterioration of a synchronization performance and to reduce an amount of calculation by calculating a correlation based on a few samples as opposed to calculating a correlation for each sample when a receiver of the acoustic communication performs synchronization while the acoustic communication is performed in the audible frequency range through modification of an audio signal or adding of a predetermined signal to an audio signal.

Synchronization system and method for transmission and reception in audible frequency range-based sound communication, and apparatus applied thereto

Provided is a data reception error reduction system and method in acoustic communication in audible frequency range, and an apparatus applied thereto. The data reception error reduction system in the acoustic communication in audible frequency range may be configured to reduce a data reception error in a receiver by taking into consideration that a sound signal is noisy and is significantly affected by a change in the ambient environment when the acoustic communication is performed in the audio frequency band through modification of an audio signal or adding of a predetermined signal to an audio signal. Accordingly, the data reception error may be reduced in the receiver even in an environment where a sound signal is noisy and is significantly affected by a change in the ambient environment, and reliability of data transmission may increase.

An oviduct specific expression promoter and a recombinant expression vector including the same. A promoter of an AGR2 gene is expressed specifically in the chicken oviduct, and a recombinant expression vector includes the promoter and a desired gene for encoding a desired protein. The oviduct specific promoter and the recombinant expression vector including the promoter can induce the expression of a protein specifically in the oviduct, i.e., an organ that secrets proteins so as to accumulate with a large amount in the egg. Accordingly, the oviduct specific promoter and the recombinant expression vector of the present invention can be advantageously used to produce transformed chickens, which can massively yield useful elements of high added value, produce functional eggs, and improve the economic traits of the poultry.

A common toothbrush usable electronic toothbrush is provided. The common toothbrush usable electronic toothbrush includes: a toothbrush receiving part having a housing for receiving a toothbrush and a fixing member for fixing the toothbrush; and a driving part tightly attached to the toothbrush receiving part, for vibrating the whole toothbrush by transmitting a vibration generated from a driving of a motor to the toothbrush receiving part. Since the electronic toothbrush can receive common toothbrushes of various kinds instead of a dedicated electric toothbrush, it is possible to permanently use the electronic toothbrush by replacing common toothbrushes, thus increasing a user's satisfaction by allowing a usage of toothbrushes as the user wishes.

Provided are methods for manufacturing improved cerium oxide abrasives suitable for forming slurry compositions suitable for CMP processes. The cerium oxide abrasives are produced by the heat treatment of a mixture of a cerium precursor compound under conditions that produce primary cerium oxide particles that are incorporated in larger secondary abrasive particles. The structure of the primary cerium oxide particles and/or the presence of incompletely oxidized cerium within the secondary abrasive particle tend to reduce its mechanical strength, thereby reducing the likelihood of damaging a substrate surface during a CMP process utilizing such abrasives.

Method for producing improved cerium oxide abrasive particles and compositions including such particles

A coil separator for a deflection yoke capable of simplifying its manufacturing process by assembling accessory components on divided neck portions and screen portions and then connecting the neck portions to the screen portions. The coil separator includes a screen portion having a band portion formed on its conical lower end, a neck portion including a wire guiding portion and a yoke clamp fastening portion, and a connecting portion for connecting the neck portion to the screen portion. The connecting portion may include a plurality of projected pins and insertion holes formed on the neck portion and the screen portion, respectively, so that the projected pins fit into the insertion holes to connect the neck portion to the screen portion. As an alternative, the connecting portion may include a spacer which has a predetermined height and is inserted between the neck portion and the screen portion to adjust the length of the screen portion.
