This paper proposes Wireless Power Transfer (WPT) system, consisting of transmitter-receiver coils along with some conditioning and stabilizing circuits. The transmitter circuit is designed with a simple H bridge circuit to supply the pulses to source coil. The efficiency variation or performance with respect to the coil size has been demonstrated in this paper, which is not well demonstrated experimentally...
With the continual increase of senior citizens more resources are required for providing care centers services. The quality of such services can be enhanced by remotely monitoring senior citizens living independently in their homes. The monitoring can be performed using various types of sensors, but the solution presented in this paper is simple, cost effective as well as easy to implement compared...
The term “Internet of Things” (IoT) refers to the expansion of Internet technologies to include smart objects by extensive deployment of exclusively identifiable distributed communication devices. The management of configuration in these devices, in particular, is a challenge due to the high heterogeneity in different communication protocols, communication sequences, and processing capabilities. We...

Knowing Total Harmonic Distortion (THD) content of voltage source inverter (VSI) is important and must be within the allowable range. Several schemes are suggested to mitigate THD and to produce as much a sinusoidal output signal as would be possible. One of such schemes is using a Sinusoidal Pulse Width Modulation SPWM-based inverter. SPWM is usually used in inverters for industrial applications...
