In this paper, we present a centralized monitoring system for infant incubator using Bluetooth. Conventional monitoring systems for incubators require large space and wire connection, which causes the spatial restrictions. To overcome this disadvantage, centralized monitoring system is proposed for infant incubators using Bluetooth. The implemented system consists mainly of transmission systems and receiver systems. There are temperature sensors, humidity sensors, ECG measurement units and Bluetooth modules in the transmission systems. For temperature, humidity and ECG data, the transmission systems acquire them from the measuring modules in the incubator and transmits the signals using Bluetooth. In the receiver system, users can see the status of the infant by accessing the central monitoring host computer. That is, one can monitor the information on the temperature and the humidity in the incubator and Infant's ECG without dependence to a conventional bulky system. Also, the system manager in the receiver system can maintain centralized monitoring of the situations in all incubators and infant. The developed system will be useful in remote diagnosis of infant incubator In various environments.

Cattle estrus detection system based on Internet of Things is designed and implemented by using Arduino pro-mini, gyroscope, acceleration sensor, bluetooth master and slave module. The implemented system measures cattle's moving and the measured data are transmitted to the computer connected to RX module by bluetooth TX module. They are plotted in 2-dimensional graph on the computer monitor and the number of transition at each sensor axis are calculated from the graph. The detected and gathered data from the system are analyzed by the proposed algorithm to decide which cows are in the estrus or not. The method to apply bluetooth scatternet is shown and the proposed system can be used to increase the success rate of artificial insemination in normal estrus by detecting the cow's behaviors such as the number of jumping. In this paper, the implemented cattle behavior detecting the system(TX module) are strapped on cattle's leg and it measures the cattle behaviors for determining where that a cattle is estrus or not by the proposed algorithm.

In this study, an E-learning system was developed for vocational rehabilitation training of intellectual disabilities. The developed system is available to have acquirement of knowledge through step by step learning and is configured to relearn through problem-solving and demonstration video. In addition, the learned information was composed to check the configuration which is correctly learning through rehearsal function. The device for rehearsal consists of a transmitter and the receiver. The transmitter is formed Pressure sensor, IR sensor for detecting client's work and Bluetooth module for wireless network. The receiver includes a Bluetooth module for wireless network and USB input terminal for communication with computer.

In this paper, we propose a system that can identify the position of naval ship personnel at a glance by utilizing the Bluetooth-based beacons. The system proposed in this paper, installs a beacon receiver which are short-range wireless communication devices for each cabin, and in the installed beacon receiver receives information from beacons held by personnel. The received information is transmitted to the processing server, and the processing server transmits the integrated information of the cabin to the display module. Display module displays personnel information located in each cabin. As a result of simulations using the designed system, it was confirmed that the integrated information is transferred to the display module and displayed. Unlike existing situations where personnel positions are reported orally within the ship, the system can quickly and in real time determine the position of personnel, allowing for the management of personnel in non-combat situations and the rapid battle disposition in combat situations. This is expected to contribute greatly to the improvement of fighting power.
