    Abstract: In a direction control antenna, a plurality of impedance elements are connected between a ground body and a radiator, a plurality of switches are connected between each impedance element and the ground body, and on/off of a plurality of switches is controlled according to a control instruction from the outside. In this case, by the turned-on switch, a radiation direction and a radiation form are determined according to short circuit positions of the radiator that is short-circuited to the ground body and the number of short circuit positions.

    Abstract: According to an exemplary embodiment of the present invention, a method for time synchronization of a first node in a peer aware communication (PAC) environment is provided. The first node obtains medium access control authority by performing contention with a second node neighboring the first node. The first node adds a time synchronization offset to the first beacon frame. In addition, the first node transmits the first beacon frame in a beacon period of a superframe when obtaining the media access control authority.

    Abstract: The invention relates to a technology for detecting an abnormal signal using a filter for removing normal sound (or normal signals) around a sensor at normal times. The filter is provided to remove normal sound based on a denoising autoencoder learning technique for removing noise and used to determine whether field sound is an abnormal signal different from that of normal times. The filter is trained to pass normal sound, regarded as noise, to output a value of 0 and pass an abnormal signal without change. The filter is retrained by collecting only normal sound rather than abnormal signals in the field and then adding the collected normal sound to the existing training data. Therefore, even machine-learning nonexperts may easily and conveniently retrain the filter.

    Abstract: Disclosed herein are a radio frequency identification (RFID) system and an operating method thereof. The RFID system includes an RFID tag and an RFID reader transmitting an initialization command to the RFID tag. The initialization command includes a field selecting a single tag accessing mode and a multi-tag processing mode. The RFID reader performs a single tag authentication procedure, which is a procedure of one-to-one accessing one RFID tag, in the case in which the field is set to the single tag accessing mode.
