Occupancy distribution estimation for smart light delivery with perturbation-modulated light sensing

Occupancy Estimation in Smart Building Using Hybrid CO2/Light Wireless Sensor Network

Smart building, which delivers useful services to residents at the lowest cost and maximum comfort, has gained increasing attention. HVAC equipment is a particularly expensive and energy consuming of building operation. A variety of emerging information technologies has been adopted. As a result, the concept of “demanddriven HVAC control” is a hot research topic. In this work, we investigated t...

Smart Environments for Occupancy Sensing and Services

The term smart environment refers to a physical space enriched with sensors and computational entities that are seamlessly and invisibly interwoven. A challenge in smart environments is to identify the location of users and physical objects. A smart environment provides location-dependent services by utilizing obtained locations. In many cases, estimating location depends on received signal str...

Fusing Sensors for Occupancy Sensing in Smart Buildings

4He Optical Pumping with Frequency Modulated Light

Recently a distributed Bragg reflection (DBR) laser diode was commercialised by SDL (USA) for helium optical pumping experiments. An interesting feature of the new device is the possibility of frequency modulation of the diode output by modulating the current intensity, leading to a new pumping scheme called optical pumping with frequency modulated light. We develop this method to induce spin p...

Integrated Fuzzy Control of Temperature, Light and Emergency Conditions for Smart Home Application

Smart home is composed of several controllers with different plants in control. If each controller works independently, without considering the mutual effect of the others in the control process, the whole system could definitely not converge to an optimum desired status and may not ever reach the demanded condition. The function of different controller system may has conflict In some condition...
