This work will show both theoretically and through experimentation that using high Q coils in the over-coupled regime supports extension of read range in near field RFID systems by 81% or more compared to the next best impedance matching strategies.
We show that with selective coding OAM states, off‐axis points and spatial variables encoded with OAM are reproducible.
We have developed a dynamic coarse integral holography approach using opto-mechanical scanning, coarse integral optics and a low space-bandwidth-product high-bandwidth spatial light modulator to display dynamic holograms with a large space-bandwidth-product at video rates, combined with an efficient rendering algorithm to reduce the information content.
In this work, we present a hybrid computer vision and RFID system that uses a novel reverse synthetic aperture technique to recover the relative motion paths of an RFID tags worn by people and correlate that to physical motion paths of individuals as measured with a 3D depth camera.
We describe techniques that allow inexpensive, ultra-thin, battery-free Radio Frequency Identification (RFID) tags to be turned into simple paper input devices.
In this work, we show how to achieve low-latency manipulation and movement sensing with off-the-shelf RFID tags and readers.
We present a low cost method for extracting the EM-ID from a device along with a new classification and ranking algorithm that is capable of identifying minute differences in the EM signatures.
We propose the Energy-interference-free Debugger, a hardware and software platform for monitoring and debugging intermittent systems without adversely effecting their energy state.
This paper discusses the practical aspects of a wireless control system and reports the experience obtained from implementing a proof-of-concept system.
This is relevant because the nRF24L01+ radio system is a popular technology for the Internet- of-Things and for location- based services with wearable devices in smart cities.
