      • Development of Illuminance Distribution Simulator for Automatic Brightness Controllable LED Underwater Fishing Lights

        Azumi IIHOSHI,Syuta KAWANO,Koichiro TANAKA 대한전자공학회 2015 ITC-CSCC :International Technical Conference on Ci Vol.2015 No.6

        There are many problems that used fishing lights in Japanese fisheries industry. It’s a particularly serious problem that is prolongation of new fisherman nature. Fishery skill acquirement that using fishing lights needs to get the feeling and experience of many time. This problem is cause of this thing. To solve this problem, we consider a LED underwater fishing lights automatic control system and development of underwater illuminance distribution simulator. This paper introduces about underwater illuminance distribution simulator of interface with the automatic brightness controllable LED underwater fishing lights in great detail. Interface of the automatic brightness controllable LED underwater fishing lights have to lead to dissipative modulus. We needed turbidity measurement. We measure coastal areas and, lend to dissipative modulus. From these results, we became possible to interface of turbidity information with automatic brightness controllable LED underwater fishing lights.

        FPGA-based Educational System Cooperating with Mobile Application for a Learning Computer Architecture

        Hiroyuki Maeda,Yoshihiro Yasutake,Azumi Iihoshi,Koichiro Tanaka 대한전자공학회 2018 IEIE Transactions on Smart Processing & Computing Vol.7 No.1

        The training of embedded software engineers in educational institutions is required for embedded systems companies. We focus on computer architecture education for learning about the operations and architectures of processors. We use the Kyutech Easily Reconstructive Naked Educational (KERNEL) system, which was designed for computer architecture education. The KERNEL system enables users to observe the internal architecture and states of processors during execution. It helps beginners to learn the basics of a computer architecture by writing their programs into the KERNEL memory so they can observe the processor’s execution. This paper describes a field-programmable gate array (FPGA)-based educational system cooperating with mobile applications, and offers a performance evaluation of its wireless communications. The system consists of an FPGA board implemented with one"s own K16 model processor that designed for computer hardware educations in the KERNEL system and mobile applications that become a console for setting and displaying the internal state of the processor. It is possible for users to write their programs, set registers in the processor, and observe the internal state of the processor during execution by using a mobile application. Communications between the FPGA and the mobile application uses classic Bluetooth and Bluetooth Low Energy technology.
