We propose a method to detect the model, location and activity of a conventional home electric appliance. Waveforms of current consumed by appliances vary according to their configurations and activity. We define feature parameters for detecting the status of appliances. A current detector, microcomputer and transmitter are equipped in a power outlet in(More)
Simultaneous Localization And Mapping (SLAM) has been an important topic for robotics. The technology will also be useful for walking navigation for, e.g., blind persons. We are developing a system using a laser range sensor and a pushcart designed to assist walking persons. Recently, interests in localization and map building with laser range sensor have(More)
The large scale database-based online modeling, called LOM, is a type of just-in-time modeling for blast furnace. In this paper, we propose a new type of LOM using a nonlinear local model to improve the performance of the long-term prediction. To estimate the parameter of the nonlinear local model, we use on-line Bayesian learning scheme with sequential(More)
