In order to fabricate microsensors, a micromachining, microfabrication technique based on LSI technologies has been used. In this paper, useful micromachining techniques are described. Examples of integrated microsensors, such as a pressure sensor including a readout circuit and a multisensor cell for blood gas analysis, are introduced. Microflow control(More)
A large number of isomorphic polygons are included in design data of large scale integrated circuit. Fast searching and classification for isomorphic polygons in these design data are able to apply to compactification of design data. Compactification of design data has a merit for communication via networks. So, we use expression method using a geometric(More)
Wireless Mesh Networks (WMNs) consist of several Access Points (APs) of Wireless Local Area Networks (WLANs) interconnected through wireless links. It is necessary to monitor the networks in order to properly operate WMNs. However, it is very difficult to always monitor WMNs. Although several researches for visu-alization system of WMNs were done, there are(More)
In this paper, we propose an power reduction method in a house which considers comfort. The proposed method assumes sensor networks which consist of smart taps, temperature and humidity sensors, light sensors, sleeping detection sensors, and human detection sensors. Furthermore, we made a modeling of the sensor networks and developed a simulation system to(More)
Recently, by development of information and communication technology, devices with communication functions have been equipped at vehicles and roads. A car navigation system, a Vehicle Information and Communication System (VICS), and an Electronic Toll Collection System (ETC) are one of the examples of these systems. By using these systems, it is possible to(More)
A large number of isomorphic polygons are included in design data of large scale integrated circuit. Fast search and classification for isomorphic polygons in these design data are expected to apply to compactification of design data and fast pattern search. A pattern matching method was proposed to reduce a large amounts of design data efficiently. In this(More)
