Adaptive power switching technique for ultrasonic motion sensors

Context, intelligence and interactions for personalized systems

“…The research topics covered in this special issue are wideranging, including context modelling and inference for smart environments (Alegre-Ibarra et al 2018; Mulero et al 2018; Nakahara and Beder 2018), localization tracking (Chen et al 2018;Xin et al 2018), optimization of energy consumption (Hammoud et al 2018), behavior mining and activity recognition (Han et al 2018;Zhang et al 2018), image analysis (Wu et al 2018), social event mining and mobile crowd sensing (Pan et al 2018;Park 2018), and behavior-based privacy (Tao et al 2018).…”

“…The application areas involved are diverse, including assistive living in smart environments (Alegre-Ibarra et al (Tao et al 2018), energy usage optimization (Hammoud et al 2018) and image segmentation (Wu et al 2018). Details for each item are briefly described below.…”

“…While paper 'FreeSense: Human-Behavior Understanding using Wi-Fi Signals' (Xin et al 2018) (Hammoud et al 2018) by Abbass Hammoud et al presents an adaptive power switching technique for ultrasound motion sensors for transmitter power level optimization to decrease energy consumption. Furthermore, an automatic sensing method can detect changes to trigger the process.…”
