Recently, augmented ultrahigh frequency radio-frequency identification (UHF RFID) systems have been developed, and they contain additional components that can detect a tag's backscattered response and use this information for the localization of the tag and other applications. The methods currently employed either have poor performance because the detection… (More)
In this paper we examine the pressure detection quality and signal clarity for two types of piezoelectric film sensors. One sensor was coated with polydimethylsiloxane (PDMS) while the other remained uncoated. Our goal was to determine how coating the sensor with PDMS would affect sensor performance. Our long-term goal is to develop a tongue-computer… (More)
Myocardial perfusion scintigraphy was made at rest and during bicycle ergometer exercise to diagnose coronary heart disease (CHD), to define the site and extent of left ventricular aneurysms, and to determine the compensatory potentialities of coronary circulation, to evaluate the efficiency of drug therapy. This was performed on a two-detector emission… (More)
An overview of academic and industry solutions to UHF RFID portals.
There have been many advances in the development and application of human computer interfaces during the past decade. We were motivated by these successful applications of human computer interfaces to design a low cost device which may also provide the user with a faster training time. In this paper we discuss the design and implementation and testing of… (More)
