This paper describes an electric power visualization system that is developed to reduce electric power consumption in a large-scale office. A small, simple, and smart power strip is developed for practical use with a newly designed built-in contactless current sensor for each outlet. Electric power visualization server used for data acquisition from each(More)
A 512 MEMS mirror array module with a hermetically sealed package for large optical cross-connects is constructed by using newly developed multi-chip direct mounting (MCDM) technology and is demonstrated to enable a plusmn5 degree rotation of the two-axis stationary operation under a drive voltage of 160 V, while having a high resonance frequency of 2 kHz
This paper proposes a cooling control method that reduces spikes in CPU temperature that occur due to fluctuation in the utilization of information communication technology (ICT) equipment based on model predictive control (MPC) for a modular datacenter. To cope with the fluctuations, the proposed method not only considers the server power consumption using(More)
