Logic-Free Building Automation: Learning the Control of Room Facilities with Wall Switches and Ceiling Camera
Hideya Ochiai, Kohki Hashimoto, Takuya Sakamoto +5
Artificial intelligence enables smarter control in building automation by its learning capability of users' preferences on facility control. Reinforcement learning (RL) was one of…
Accurate Radar-Based Heartbeat Measurement Using Higher Harmonic Components
Itsuki Iwata, Kimitaka Sumi, Yuji Tanaka +1
This study proposes a radar-based heartbeat measurement method that uses the absolute value of the second derivative of the complex radar signal, rather than its phase, and the var…
Noncontact Detection of Sleep Apnea Using Radar and Expectation-Maximization Algorithm
Takato Koda, Shigeaki Okumura, Hirofumi Taki +5
Sleep apnea syndrome requires early diagnosis because this syndrome can lead to a variety of health problems. If sleep apnea events can be detected in a noncontact manner using rad…
Radar-Based Noncontact Measurement of Heartbeat of Humans and Chimpanzees Using Millimeter-Wave Radar with Topology Method
Itsuki Iwata, Takuya Sakamoto, Takuya Matsumoto +1
This study proposes a method to determine the filter parameters required for the topology method, which is a radar-based noncontact method for measurement of heart inter-beat inter…
Radar-Based Estimation of Human Body Orientation Using Respiratory Features and Hierarchical Regression Model
Wenxu Sun, Shunsuke Iwata, Yuji Tanaka +1
This study proposes an accurate method to estimate human body orientation using a millimeter-wave radar system. Body displacement is measured from the phase of the radar echo, whic…
