As a society advances, an aging phenomenon and many diseases which did not exist in old times are happening. Especially, in case of the aged patient, because we cant know the time the condition of the patients health become worse, the study of the Tele-information system has been actively carried out by the necessity of a persistent observation. A ECG signal a kind of a vital signals has been widely used to the medical information system as an usual clinical diagnosis for the patients who possess heart diseases. BlueTooth is a close range wireless communication technology which uses a wireless frequency 2.4GHz and has a high trust and self - error correction technology according to a low power consumption quality and a high-speed frequency hopping. This makes get a high trust concerning a data transmission than an existing modem. In addition, though wireless modem is restricted by a minimal of a wireless terminal, It will be possible to coincide with the function of the portable with the low power consumption quality by using Bluetooth. And as the system on a chip of module progresses, the possibility of the small size is present According to this, Bluetooth module transmits the medical information, which is input from the outside among the operations that use the Bluetooth to the Bluetooth module that is connected the host PC. And the system that the host PC transmits the medical information from the connected Bluetooth module to the Internet has once embedded. this study let the host PC embedded in advance of the existing system and transmit the medical information by the addition of the Tcp/Ip protocol stark under all embedded environments to internet.

In this paper, we deal with implementing design for a correlator access code generator module which they are used for setting up a connection between units, a packet decision, a clock syncronization, by FPGA. The orrelator module which is composed of the Wallace Tree's CSA and threshold value decision device decides useful a packet and syncronizes a clock, after it correlates an input signal of 1 Mbps transmission rate by a sliding window. An access code generator module which is composed of a BCH (Bose-Chadhuri-Hocquenghem) cyclic encoder and control device was designed according as a four steps' generation process proposed in the bluetooth standard. The pseudo random sequence which solves syncronization problem saved a voluntary device Proposed the module was designed by VHDL. An simulation and test are inspected by Xilinx FPGA.

In this paper, we describe the implementation of Bluetooth headset. Bluetooth headset sets up link using ACL connection between headset and audio gateway, transfers 64kbps voice using SCO connection. Bluetooth headset implemented in this paper is designed with no HCI, so all protocol stack is implemented in Bluetooth module. We verify the upper layer protocol and application program using C-language modeling on Unix environment.

As the portable medical equipments consume the power and transmission of the information, they need the system to use long. Although the current wireless transform systems for medical equipments use Bluetooth protocol system, an electricity consumption is big because it uses long and there is the difficulty in the utility We designed a module using the Zigbee protocol which an electricity consumption is more small though a transmission speed is slower than Bluetooth and drew the plan the wireless transmit system for medical equipments to use long.

In general, existed kiosk using touch-screen based kiosk system has been used by only single user, so that multiple users to access this kiosk need to provide a lot of waiting time and maintenance costs. To solve this problem, the framework design based on Bluetooth profile for kiosk servers is presented. The proposed kiosk system can be more efficiently used in theater, train station, bank, government, and public offices by using Bluetooth module and AP in mobile system such as smart phone.

Bluetooth technology of cable replacement and infrastructure access is verified enough to be commercialized as goods. But there are a lot of works to implement ad-hoc Bluetooth radio network. for this, scatternet must be formed. We propose routing layer, packet format and link formation schemes for scatternet. The page procedure of the route request and the route reply page eliminates the procedure of the inquiry and the master-slave role switching. The route discovery time could be lower than 50msec within the distance of 50m. Proposed link formation scheme lets master, slave and bridge establish connection automatically and offers active ad-hoc environment. Devices that adopt Bluetooth module of 10m transmission range can communicate with other devices far away without any intervention of users.

In this paper, we propose and develop software controllable mobile controller contents using bluetooth concepts. The main features of the propsed system are as follows. Bluetooth communication is used for between smart phone and bluetooth. We develop two kinds of programs, clients and server, in which clients requests bluetooth communication and server responds. It's controllable to move toward the previous page and next page, and GUI environments can give efficient user oriented services. The results of performance evaluation show relatively good performances in view points of prices, functions, and portability.

Distributed Autonomous Robotic System (DARS) is defined as a system that independent autonomous robots in the restricted environments infer their status from pre-assigned conditions and operate their jobs through the cooperation with each other. In the DARS, a robot contains sensor part to percept the situation around themselves, communication part to exchange information, and actuator part to do a work. Especially, in order to cooperate with other robots, communicating with other robots is one of the essential elements. Because Bluetooth has many advantages such as low power consumption, small size module package, and various standard protocols, Bluetooth is rated as one of the efficient communicating technologies which can apply to small-sized robot system. In this paper, we will develop Bluetooth communicating system for autonomous robots such as DARS robots. For this purpose, The Bluetooth communication system must have several features. The first, this system should be separated from other robot parts and operate spontaneously and independently. In other words, this communication system should have the ability to organize and maintain and reorganize a network scheme. The next, this system had better support any kinds of standard interfaces in order to guarantee flexible applicability to other embedded system. We will discuss how to construct and what kind of procedure to develop the network system.

In this paper, we describes the development of Bluetooth network Access Point(AP) for the access network connection of Bluetooth devices at home. Unlike headset, mouse, and keyboard, the AP should have capability to support multiple connection and stabilized network throughput. Our AP allows various kinds of Bluetooth terminals to access the access network like xDSL and PSTN(Public Swithced Telephone Network) stably. Especially, users can access the PSTN at home instead of expensive CDMA network through the AP by using the one-phone which is the cellular phone with the Bluetooth module.

The Internet of Things (IoT) is a term first used by Kevin Ashton, director of MIT's Auto ID Center, in 1999, and refers to the connection of things to the Internet. Bluetooth, one of the wireless networks, is a technology developed as an industry standard for personal short-range wireless communication first developed by Ericsson in 1994. Since the Raspberry Pi has Bluetooth built-in, a wireless network is possible. This paper implements a module for the Internet of Things by implementing serial communication in the Bluetooth built-in Raspberry Pi 3 B+. There was a problem that Bluetooth communication was impossible between raspberries, so the discovery function was activated and serial communication was added to successfully link the communication.
