Abstract: A group pairing method of a wireless intercommunication system according to an embodiment may comprise the steps of: acquiring information about slave wireless intercommunication devices and generating a pairing list from the acquired information, and sorting the generated list according to a chain connection order; transmitting information about the sorted pairing list and chain connection order to a master wireless intercommunication device; the master wireless intercommunication device receiving the information about the sorted pairing list and chain connection order from the master mobile device and updating the pairing list thereof from the received pairing list, and transmitting information about the updated pairing list and chain connection order to the slave wireless intercommunication devices; and each of the slave wireless intercommunication devices receiving the information about the updated pairing list and chain connection order from the master wireless intercommunication device and updating the

Abstract: Provided is an apparatus capable of fixedly affixing a camera onto an uneven surface or surfaces that are of different angles or heights to each other, while allowing for a high degree of freedom of movement. The apparatus includes a camera connection platform equipped with a camera mounting unit in the upper portion of the apparatus onto which a camera is securely fixed; an upper body pan connected to the lower portion of the camera connection platform that allows the upper body an to pivot multi-axially, a lower body part connected to the lower portion of the upper body part; two legs connected to both ends of the lower body part in a o manner that allows the legs to pivot multi-axially; and suction cups, each of which is attached to each of the other ends of the two supports.

Abstract: A multitasking system of a Bluetooth headset, which enables users to talk with each other in a telephone call while at the same time enjoying media content played by an external Bluetooth device. The multitasking system of a Bluetooth headset includes: a first Bluetooth headset worn by a first user, and a second Bluetooth headset worn by a second user. The first Bluetooth headset is configured to include a first Bluetooth module, and a second Bluetooth module that is connected to the first Bluetooth module. The second Bluetooth headset is configured to include a third Bluetooth module that is paired with the first Bluetooth module, and a fourth Bluetooth module that is connected to the third Bluetooth module.

Abstract: A remote audio recording camera system, which enables users to communicate with each other even when they are far from each other, and which synthesizes speech data of users to store the synthesized speech data in a Bluetooth camera. The remote audio recording camera system includes: at least one first Bluetooth headset configured to be worn by a first user; a second Bluetooth headset configured to be worn by a second user that communicates with the first user, and to synthesize speech data of the first user received by the first Bluetooth headset and speech data input from the second user by using a speech synthesizer to transmit the synthesized speech data; and a Bluetooth camera configured to include a speech storage that stores the synthesized speech data received from the second Bluetooth headset, and an image storage that stores captured images.
