Industrial application of AI-based control technology

For the next ten years, new technologies such as AI, big data, and IoT evolve and spread in a wide range of fields. Industry structure will also be greatly affected by these technologies. We are developing AI technology-based energy harvesting system, process control system and so on. For example, the self-powered system based on vibration power generation combined with the deep learning technique is applied to drive a wireless sensor node for factory diagnosis. In the process control system, the temperature is precisely controlled by using a learning algorithm based on the neural network.

Producing next generation media technology

Rapid progress of high-speed image processing and image projection technologies is increasing demand for, high-speed, adaptive image acquisition and projection. Our laboratory proposes a new media technology named Dynamic Image Control (DIC) that refers to a technical concept of dynamic and adaptive control of image acquisition and/or projection depending on the scene. DIC requires optimization of all components of imaging and projection systems, including imagers, optics, and illumination. Thus, both devices and system/application are studied in this laboratory. Envisaged application fields of DIC are image industries such as film and advertising, medicine and biology requiring microscopic measurement, factory automation, and human-machine interfaces requiring comprehensible images.

Student’s voice

My current research is about electro-magnetic interference (EMI) reduction techniques in switching power converters. EMI problem is a big issue for electronic appliances; if they do not meet EMI regulations, they cannot be in the commercial market. Then the EMI noise spectrum spread technique of suppressing the peak levels at the fundamental frequency is widely used. However, it spreads the EMI noise also in the radio receiver signal band, which disturbs the radio receiver erformance. Based on this background, my research target is set to reduce the EMI noise diffusion at the specific frequencies (radio receiver bands) when the EMI spectrum spread technique is employed. I have come up with new ideas to solve this problem, verified them with simulations and experiments, and presented their contents in international conferences.
