Improvement of Smart Wearable Device to Assure Right Direction for Elderly People

Wearable Smart System for Visually Impaired People

In this paper, we present a wearable smart system to help visually impaired persons (VIPs) walk by themselves through the streets, navigate in public places, and seek assistance. The main components of the system are a microcontroller board, various sensors, cellular communication and GPS modules, and a solar panel. The system employs a set of sensors to track the path and alert the user of obs...

application of upfc based on svpwm for power quality improvement

در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...

Smart - Device - to - Smart - Device Communications

Device-to-device (D2D) communications have been identified by the Third Generation Partnership Project (3GPP) as a potential candidate technology to offload heavily used cellular communication systems. Even though D2D communications has been around in industry and research for the last two decades, the 3GPP decision to include this concept in the cellular context is groundbreaking. There are se...

Choosing the Right RF Switches for Smart Mobile Device Applications

Modern smart phones and tablet computers typically incorporate multiple wireless services at different frequency bands ranging from FM radio to LTE. At the same time, an increasing number of designs utilize more than one antenna to enhance sensitivity and suppress cross talk. Both trends place the miniature RF solid-state switches in an increasingly crucial role in smart mobile device RF front ...
