Presbyopia is age-related loss of accommodation that gradually impairs near vision. Few studies have examined the burden of presbyopia in the United States of America (USA)1,2 and none have examined it in economically disadvantaged or minority populations, in which there are increased rates of visual impairment and decreased use of eye care services.3,4 In our study, individuals ≥35 years of ag...

This work presents the development of a portable, wireless activity monitoring system for the estimation of biomechanical gait parameters. The system uses a pair of instrumented insoles able to measure pressure from different points of the foot including four commercial piezoresistive pressure sensors and a three-axis accelerometer, all together integrated in the insole to determine foot forces...

The use of Radio Frequency Identification (RFID) advancement is turning out to be rapidly transversely over an extensive variety of business undertakings. Engineers apply the development not simply in customary applications, for instance, asset or stock after, also in security organizations, electronic travel papers and RFID-embedded card. In any case, RFID development moreover brings different...

Learning and studying are very often connected with reading printed materials. In this paper we describe some implementation issues of a common task – printing a document, when applied in a mobile environment. In a non-mobile context this task is simple and is usually taken for granted, but the introduction of a palmtop/laptop equipped with a wireless-LAN card makes the task less trivial. To fu...

PURPOSE To assess visual performance and the effects of color overlays on reading in children who were deaf and children who could hear. METHODS Thirty-one children who were deaf (mean [± SD] age, 14 [± 1.99] years) and 39 children who could hear (mean [± SD] age, 13.58 [± 3.09] years) underwent an optometric examination with specific emphasis on near vision. Participants chose an overlay wit...

Cheap and effective system for parking avoidance of the car without permission at Disabled Parking Permit: DPP spaces is proposed. The proposed system is validated through some experiments. Multiple methods for detection of car in the DPP space using ultrasound sensors, Near Infrared: NIR cameras, RFID writer and reader with IC card, IC chip and IC tag as well as ETC system and GPS receiver are...

NFC (Near Field Communication) technology facilitates mobile phone usage of billions of people throughout the world that offers diverse services ranging from payment and loyalty applications to access keys for offices and houses. NFC technology is one emerging and promising technology that have adopted smart card as secure element (SE) to provide a secure area for the execution of multiple appl...
