This paper presents the design and implementation of a multi-standard energy management system, which leverages heterogeneous devices to convert existing buildings into Smart Buildings. Its main purpose is to increase the energy efficiency of buildings providing user awareness to promote green behaviors. The proposed solution has been designed to enable interoperability across different standards...
In the emerging Internet of Things (IoT), consumer electronics are important components to create a smart environment. Embedded systems, which have internet connectivity in their limited resource, are often equipped with separate MCUs for device control and wireless communication. However, this approach is not cost-effective because of multiple MCUs. To solve this, we propose an IoT framework which...
In order to improve the unmanned sales of agricultural products, we are researching and developing an Unmanned Agricultural Product Sales (UAPS) system combining an embedded system called the UAPS shop system, a server system and a mobile system. Up to date, implementation of the UAPS shop system and an initial prototyping of the sever/mobile system have been completed and evaluated. This paper describes...
Many standardization activities have been done for controlling and managing home networks and appliances during past ten years. Such activities include UPnP/DLNA, ECHONET and Continua Health Alliance and so on. However, there is no compatibility among those standards. To solve those problems, we have developed overlay networking protocols and device metadata technologies as a solution for controlling...
TV sets and companion devices (Smartphones, Tablets, etc.) have outgrown their original purpose and are now playing together an important role to offer the best user experience on multiple screens. However, the collaboration between TV and companion applications faces challenges that go beyond traditional single screen applications. These range from discovery, wake-up and pairing of devices, to application...
Unmanned sale is widely adopted in Japan as a way of direct sales of agricultural products. It has, however, problems that change is not handled, receipts are not issued, deferred payment is not acceptable, and all sales management must be done by farmers themselves. The UAPS (Unmanned Agricultural Product Sales) system aims to solve these problems. We completed development of an implementation for...
