Abstract: A short-range wireless communications apparatus according to one embodiment includes a short-range wireless communications unit and a control unit. The short-range wireless communications unit is configured to communicate with a terminal device configured to provide a call service and a predetermined artificial intelligence service. The control unit configured to control the short-range wireless communications unit so that when the call service is provided, media data related to the call service is transmitted and received between the short-range wireless communications unit and the terminal device through a first channel, and when the artificial intelligence service is provided during the call service being provided, media data related to the artificial intelligence service is transmitted and received between the short-range wireless communications unit and the terminal device through a second channel separated from the first channel.

Abstract: 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.

Abstract: A bed covering apparatus that prevents bed bugs from intrusion to an enclosed sleeping area, wherein the bed covering apparatus has a net for exclusion of insects and an openable section disposed at one end of the net that is dimensioned to accommodate legs of a person sleeping within the net, and also contains at least one slippery section to which bed bugs cannot adhere, thereby causing the bed bugs to fall from the netted sleeping area before they have an opportunity to enter the sleeping enclosure. The bed covering apparatus further may comprise straps to securely attach it to a mattress.

Abstract: An apparatus for trapping insects, such as bedbugs, that are attempting to access beds and other pieces of furniture, the insect trapping apparatus has an adhesive surface that peripherally encircles an inner non-adhesive supporting surface. Users of the insect trapping apparatus place the support posts of beds or other pieces of furniture on the inner non-adhesive supporting surface. The insect trapping apparatus has an outer non-adhesive surface that peripherally encircles the adhesive surface, and the outer non-adhesive surface has channels therethrough with openings to the adhesive surface to permit transit of insects from outside the insect trapping apparatus to the adhesive surface.
