Abstract: This invention relates to a method of forming a copper film on a Mo/SUS flexible substrate, which enables the copper film to be uniformly formed on the Mo/SUS flexible substrate in a short period of time by applying current and in which the copper film becomes thicker in proportion to an increase in a concentration of a copper precursor aqueous solution or in a current density.

Abstract: An UWB-based indoor positioning system using out-of-band management includes a plurality of nodes that individually broadcast an UWB broadcast message through an ultra-wide band (UWB) channel; and a remote positioning server for receiving a response message to the UWB broadcast message through an out-of-band network, calculating a time of flight (ToF) between the nodes based on the identification information and timestamp information of each of the nodes included in the response message and producing a positioning information of each of the nodes by calculating a distance between the nodes using the calculated ToF. The UWB-based indoor positioning system and method using out-of-band management can significantly improve node scalability and flexibility in the UWB positioning system through the unification of processes between anchor/tag nodes and simplification of the initial registration procedure.
