In the present communication, the basic D flip flop has been considered with TSPC (True Single Phase Clock) logic for designing a novel 4-bit counter on 45 and 32nm technology. Here, it was with average power of 309 μWatts and 166.8 μWatts, which is very high on the respective technologies. The challenge is to reduce the average power and off state leakage power. To consider the challenge, two different techniques have been considered for power saving as, sleeping transistors and technique, modified TSPC D flip-flop (modified version In comparative study of simulations, it is observed that employing modified version of TSPC D flip-flop shows the most optimum results in terms of propagation delays and average power. Average power has been obtained as 260.3 μWatts which is 15.76% less than base counter on 45nm technology, and 133.2 μWatts which is 20.14 % less on 32nm technology. Moreover, Transistor sizing has also been used for separate analysis in which case the average power consumption has been found most minimum in 6/4 aspect ratio as 196.6 μWatts and 70.31 μWatts in both technologies respectively, among 6/4, 5/3 and 4/2 ratios.
Internet of Things (IoT) primarily based application requires integration with the wireless communication technology to make the application data with ease available. In this paper, a modified 12 mm x 16 mm x 1.6 mm micro strip patch antenna has been proposed for IoT applications at 2.4 Giga Hertz (GHz) in the Industrial Scientific and Medical (ISM) band. This wideband antenna is designed using Flame Retardant4 (FR4) material as the substrate. The multiband operating characteristics have been achieved by radiating strips to the 50 feed line. Proposed wideband antenna covers frequencies ranging from 1.8 GHz to 3 GHz and 5.3 GHz to 6.9 GHz for -10 dB return loss. The results are analyzed and discuss in term of return loss, Voltage Standing Wave Ratio (VSWR), efficiency and gain. The proposed design has a maximum losses of -31.59 dB at 2.4 GHz and -16.94 dB at 6 GHz. The developed antenna can be useful for several wireless communication applications, such as 2.4 GHz Bluetooth, Wireless Local-Area Network (WLAN) (2.4/5.8 GHz), Worldwide Interoperability for Microwave Access (WiMAX) (5.5 GHz), ISM band and IoT applications.
Using Radio Frequency Identification (RFID) technology, this work aims to create an intelligent traffic system. It is developed and operated in such a way that fines are tracked independently. RFID technology, passive tags, a processing unit (computer), and a communication system were all utilized with low-cost equipment. The first level is represented by data collection via RFID, which scans any identifiable tag connected to cars. After that, information is received by server on internet connection. Modern era is usually growing with an aim to make people's each day obligations easier. One of the major issues facing developing cities is traffic management, which is exacerbated by increasing population density and vehicle numbers without expanding roads. Road congestion wastes time and fuel, resulting in increased pollution. This observe demonstrates that growing a traffic management system with the use of the Internet of Things (IoT) is achievable and inexpensive.
The proposed work examines the performance of control system in a Compound Heating Resistance (CHR) furnace heated, using two different heating elements, Silicon Carbide (SiC) heating rods and Molybdenum Di-Silicide (MoSi ) 2 heating elements for 1600ᴼC working chamber temperature. The system under study consists of Programmable Proportional Integral Derivative (PPID) controller, Thyristor (is also known as Silicon Controlled Rectifier) power pack, recrystallized alumina tubes, sensing elements: thermo-couple, Pt-Pt/13%.Rh, semiconductor based circuit that controls power and current to system according to the requirement (step down) and thereby control voltage automatically with transformer (depending on size of working area, and 53 amp (I), 220 V for single phase, reduced to 60 V by a step down transformer) auto current limiting facilities. Present work is designed for programmable as also for nonprogrammable type of cycles of operations set before starting the furnace within maximum working temperature of 1600ᴼC to achieve objectives, like, saving of amperage (current consumption of 53 amp) and power at reduced voltage (40V), long life of the heating elements (2 years and more) and optimization of thermal efficiency (60%) for high working temperature 1600ᴼC for long hours of operation in a CHR furnace.
Modern technology has revolutionized automation. Security is at high priority with increasing automation. Today, to help people feel comfortable, video surveillance cameras are installed in public places like schools, hospitals, and other buildings. The main goal of this research work is to automatically collect vehicle images with a camera using a Raspberry Pi and recognising the licence plate of the vehicles. Vehicle number plate recognition is a challenging but crucial system. This is highly helpful for automating toll booths, identifying automated signal violators, and identifying traffic regulation violators. In this work, a Raspberry Pi is used for vehicle license plate recognition, which uses image processing to automatically recognize license plates. Incoming camera footage is continuously processed by the system to look for any signs of number plates. When the camera detects a number plate, Optical Character Recognition (OCR) technique is used to process the image and extract the number from it. The distance to an object is calculated by a sensor utilizing sound waves. The extracted number is then displayed by the system. This can be used for additional authentication.
