Abstract: The present invention provides a metal-plastic composite material having excellent adhesive strength and formability and a method for manufacturing the same, and specifically, the present invention provides a metal-plastic composite material and a method for manufacturing the same comprising: a metal layer; and a plastic layer on at least one surface of the metal layer, wherein a thin film layer formed of a silane coupling agent is provided between the metal layer and the plastic layer, and the metal layer and the plastic layer are bonded by covalent bonding with the silane coupling agent.

Abstract: A bump stopper can be provided for a vehicle. The bump stopper includes an upper part, a lower part, and a connection member. The upper part and the lower part are stacked vertically and have double density. The connection member is positioned at an interface between the upper part and the lower part to connect the upper part and the lower part.

Abstract: A wireless communication system, according to one embodiment of the present invention, comprises: a first communication module; and at least one second communication module wirelessly connected to the first communication module, wherein the first communication module is wirelessly connected to the second communication module to which driving power is applied from the same power source as that of the first communication module.

Abstract: The present invention relates to a method and an apparatus for determining a location of a device using multiple antenna switching.

Abstract: According to an embodiment, provided is a Bluetooth device comprising a master module and at least one slave module, wherein: the master module operates in an active mode when a mobile communication device is located within a pre-set range and switches to a power saving mode when the mobile communication device deviates from the pre-set range; in the active mode, the master module performs data communication by being connected to the mobile communication device located within the pre-set range and operates the Bluetooth device by periodically exchanging a packet with the slave module; and in the power saving mode, the master module operates in at least one of a first mode in which a packet exchange cycle with the slave module is adjusted from a first interval to a second interval, and a second mode in which a connection between the master module and the slave module is released.
