Design and Development of IOT based Low Power Consumption in Employee Meeting Rooms

In this paper, We design and implement IOT based low power system that can be used in employee meeting rooms. The design is based on number of employees entering and leaving the room and automates room AC, lights and room freshners using relay device. The system designed counts number of employees entering the room using IR device and updates the number using counter and automates electrical appliances of the room and when leaving automatically switches off the devices. The power consumed is updated using ESP 8266 in the cloud called thing speak where the data can be evaluated and analyzed per day and per month. The system has 20*4 LCD which displays the complete details of the employees and electrical appliances. The working of the system starts with the entering of an employee in the room, the buzzer beeps and LED turns on. Arduino Mega is used as a central processor that controls all the appliances. The code is written in C and simulation is done using Proteus ISIS. Finally, the implemented system shows the energy consumption per day and per month and a detailed comparative analysis is done with and without connecting the system which shows a better saving of energy in the employee room. The methodology adapted for our work is V-methodology.

Application of the Bolton Relay Device for Thoracic Endografting In or Near the Aortic Arch

Endovascular correction of aortic arch pathology remains a challenge, with a variety of techniques proposed over the years to minimize complications and enhance the probability of a successful result. A variety of approaches have been developed in order to deal with the aortic arch pathology and its idiosyncrasies. We review potential interventional techniques for the repair of aortic arch pathologies, beginning with conventional aortic arch surgery, followed by hybrid treatments and those along the endovascular spectrum (parallel and fenestrated endografts, scalloped endografts, and ascending and new branched endografts). We finish with an overview of all the Bolton Medical (Barcelona, Spain and Sunrise, FL, USA) thoracic platforms. Endovascular techniques show acceptable results in selected cases. Both proximal Bolton Relay configurations (with and without a bare stent) offer conformability and accuracy on deployment with very low rates of stroke. Fenestrated and scalloped designs are also useful for selected cases. Ascending and branched Bolton devices are very promising platforms for a serious, full endovascular approach to the aorta.

Development of Relay Device in Monitoring Data Management of Cable Circulation in Urban Power Grid

The monitoring points of cable circulation in cities are relatively scattered. The on-site collection devices restricted by the power supply, installation site and communication distance are usually unable to store large amounts of data or transmit data over a long distance. In this thesis the relay device of data management is developed, realizing the management and sorted storing of the data of the collection devices of close-distance wireless receiving data, and sending the data to remote places through the GSM/GPRS network. Therefore the scattered data can be transmitted to computer analysis and management system over a long distance after centralized processing of scattered data and long-distance data monitoring and comprehensive analysis can be realized.
