Near Field Communication (NFC): A Review on Application and Challenges
Abstract: A set of wireless communication protocols known as near-field communication (NFC) allows two electronic gadgets to communicate with one another at little more than 4 cm (1.57 in). NFC, with a simple configuration, provides a low-speed connection that can be utilized to establish stronger wireless networks. Like other "proximity card" technologies, NFC operates through inductive coupling between two "antennas" found on NFC-enabled devices, such as a printer and a smartphone. …

Deposition and Characterization of ZnO Thin Films by Thermal Vacuum Thermal Evaporation Method for Photoconductive Sensor Application
Abstract: In this work we have deposited ZnO thin films using thermal evaporation method. The films have been deposited on silicon substrate for structural characterization and on glass substrate for optical characterization. The structural, surface morphology, optical properties and electrical properties of ZnO thin films were investigated systematically using X-ray diffractometer (XRD), scanning electron microscope (SEM), atomic force microscopy (AFM), ellipsometeric measurement and semiconductor parameter analyzer respectively. The deposited ZnO thin …

Encrypted Visible light communication for optimum performance
Abstract: Visible light communication (VLC) is regarded as the relatively secure communication when compared with other wireless communications using radio frequency (RF). The original visible signal sending from the lamp can be first received by the proposed light encrypter. The information can be encrypted and then emitted. The light encrypter acts as an encryption gateway for signals in the optical domain. The rolling shutter effect of the complementary metal–oxide semiconductor (CMOS) …

Design of reliable electronic door lock system on PCB using Ki-CAD
Abstract: This paper deals with the design of a PCB based electronic door lock system. An electronicdoor locking system is one which uses passwords, RFID tags and readers, fingerprints, etc.instead of the traditional key system. In my project, I made use of a numeric cipher to unlocka door. The door can be unlocked only by the people who are aware of the code. Thisincreases the security and safety by preventing unauthorized …

An Improvement of Out-of-Band Suppression in Common-Gate LNA with Transformer-Based Input Matching Network for BLE Applications
Abstract: The purpose of this paper is to improve out-of-band suppression in capacitive cross-coupling common-mode LNA with transformer-based input matching for BLE applications. Starting from an overview of the transformer-based matching network, the problematic issue is addressed through analytical considerations and its solution is presented. Transformer-based matching introduces an undesired peak response by an extra conjugate pole pair owing to the imperfect magnetic coupling of the transformer which degrades the suppression …

Effect of Electromagnetic Interference and Different Counter Techniques -Electromagnetic Compatibility
Abstract: Electromagnetic Interference (EMI) refers to any electromagnetic (EM) disturbance that intrudes, hinders, degrades or bounds the actual performance of a piece of electrical/electronic equipment, transmission channel, or other susceptible systems. It can occur in any part of the EM spectrum from frequencies of 0 Hz (d.c.) to 20 GHz or higher, but though utmost predominant in the radio frequency (RF) region. The electromagnetic environment is the significant part of the …

Accelerometer-based Hand Gesture Controlled Robot Car Using Arduino
Abstract: This paper introduces a gesture controlled user interface (GCUI) template and discusses software, application and usability patterns. It provides an integrated approach to real-time detections, gesture-based information that control the movement of vehicles, and user gesture manipulation using hand movements. Adaptation is a three-axis accelerometer. The accelerometer also moves accordingly as the person moves his hand. The movement is accelerometer-captured and gesture-processed. Today, communications between human beings are moving away …
