Öğe Autonomously Controlled Intelligent Wheelchair System for Indoor Areas(Institute of Electrical and Electronics Engineers Inc., 2021) Sahin, H.I.; Kavsaoglu, A.R.Autonomously controlled intelligent wheelchair is an electric wheelchair system that can reach a desired position by finding paths without any need for user intervention. Pathfinding can be performed in outdoor areas with the support of global positioning system (GPS) while interior mapping is required for indoor areas. In this study, an autonomous control interface design that can work with intelligent wheelchairs has been implemented to be used on indoor areas. This interface is used building floor plans and pathfinding algorithms for planning a path to a selected destination. The autonomous control of an electrically powered wheelchair is performed using fuzzy logic on the planned path. On the hardware side, a depth camera, a single board computer, microcontrollers, speed sensors, lighting systems and a motor driver are added on the electric-powered wheelchair. All components are operated under the coordination that provided with the interface. The instantaneously detection of obstacles that may be encountered causes the path to be changed with an alternative, and this situation can be shown synchronously within a simulation software. © 2021 IEEE.Öğe C# Interface Design for Real-Time Signal Recording Oriented of Bionic Hand Control with Leap Motion and EMG Devices(Institute of Electrical and Electronics Engineers Inc., 2020) Kavsaoglu, A.R.; Bilece, B.; Altiyaprak, B.; Böyükçolak, F.There are people who have a lost limb or have no innate limb. In this study, it is aimed to create a data processing environment to improve the working performance of the prostheses to be developed for people with hand loss. Basically, Leap Motion and EMG devices were used. Simultaneous recording of data obtained with EMG and Leap Motion is provided using Arduino microcontroller and C # Interface design. In addition, a bionic hand control is provided from finger movements obtained with Leap Motion. © 2020 IEEE.Öğe Heating/Cooling Block System Design with Thermoelectric Module(Institute of Electrical and Electronics Engineers Inc., 2020) Kavsaoglu, A.R.; Demir, H.; Sungur, H.The aim of this study is to design and develop a system for polymerase chain reaction devices. Temperature is an important criterion for the realization of polymerase chain reactions, which is a simple and precise technique. Equal temperature stability must be achieved on the hopper aluminum block used for the placement of PCR tubes in equal time. By using the Peltier effect of the thermoelectric module, electric energy is converted to heat energy due to the temperature difference between the surfaces. In the study, the Peltier effect is to ensure that the samples placed in the aluminum block are kept at the desired temperature during the desired time. The thermoelectric modules used for this system were operated in heating/cooling modes and the values obtained with the temperature sensor used were drawn as temperature-time graph on the interface screen designed momentarily. PCR devices are commonly used in the areas of DNA amplifications, activation of incubation and cultures, serum coagulation, melting/boiling points, nucleic acid hydridizations, and PCR testing. © 2020 IEEE.Öğe Remote Monitoring System for Incubator Data(Institute of Electrical and Electronics Engineers Inc., 2018) Tan, K.; Kavsaoglu, A.R.; Koçak, O.; Akbay, C.In this study, an electronic system has been developed to collect data from the incubator devices in the neonatal intensive care services to allow the remote monitoring and control of authorized personnel via the internet interface. Temperature and humidity values of the environment obtained from the designed system are calculated and displayed instantly on the user panel. Pulse, body weight, body temperature and blood-oxygen saturation values which are critically important are detected by high-precision sensors placed on the body surface and transferred to the internet interface screen. In this way, it is expected that this system and the staff working in hospitals and obstetrics clinics will be able to solve the workload and medical data losses. © 2018 IEEE.
