Single-phase inverters are widely used to connect small-scale distributed renewable energy sources to the grid. However, unlike a three-phase system, designing the vector control for a single-phase inverter is more challenging. This paper presents a neural network based vector control technique for a single-phase inverter, as well as how to develop and design an embedded digital control system to...
Bluetooth Low Energy Beacons currently provide a great potential for indoor localization to users with smart devices. This paper implements a security concept to mitigate weaknesses of current beacon concepts against forgery and request tracking. The method authenticates beacons with dynamic data by attaching secure signatures. The architecture is especially useful as a many-to-many solution. A test...
This paper describes a design and implementation of a smart infrared (IR) remote control which can be used for various home appliances. The entire system is based on microcontroller that makes the control system smarter and easy to modify. It enables the user to operate a T.V, Air Conditioner and other Home appliances from about 10 meters away. This Smart remote control can incorporate all infrared...
A high-performance mixed-signal controller, based on the V2 architecture, has been designed to regulate a high-frequency (up to 10MHz) 16V-input synchronous buck converter with integrated driver and power stage in a 130nm Bipolar-CMOS-DMOS (BCD) technology. The inner loop has been implemented fully in the analog domain to support high switching frequencies, while the outer loop has been realized digitally...
The stroke and spinal cord injury patients, elders and physically challenged who are affected by higher degree of disability such as quadriplegia, are not able to extensively use the powered wheelchairs for long periods of time. The major reason is that they are not able to provide the continuous physical effort required to guide the powered wheelchair which has joystick control mechanism as a standard...
Data acquisition (DAQ) is a process of bringing a real world signal in to the computer for processing, analysis, storage or other data manipulation. Here in this paper not only the process of data capture from real world in real time, also the process of data feed to real world in real time from computer in different format is also discussed with a developed user friendly Graphical User Interface...
This paper presents a design for a low-cost research robot based on the chassis of a Hexbug Spider, a remote controlled toy robot. Our modification replaces the robot head with a 3d printed adapter part which provides space for sensors, a larger battery, and a microcontroller board. In a second part of the paper we address the manufacturing process of such a robot. The presented robot costs far less...
Multiple Outputs Programmable Integrated Circuits (MOPICs) trainer for educational applications is fabricated based on unsatisfactory usage of PIC simulation which is not able to achieve the learning outcome especially in enhancing leaner's hands-on skill through circuit designing, connection and trouble shooting. Current PIC programming is done through computer simulation, cause the leaners facing...
Now-a-days, the sales centres are using Digital Weighing Machines (DWM) for precision measurement of weight, acquisition of rate from keypad and computation of cost. The weight, rate and cost are shown on 7-segment bright display devices. The implementation of a DWM can be carried out using various types of hardware topologies and accordingly the cost varies. The FPGA based DWM is the most competitive...
At present times, the Electricity Company supplies LCD-type Electrical Energy Meters (LCDEM), and mount them on the outdoor panels. The users cannot time-to-time monitor the consumed energy units to asses that the consumption is exceeding their budget, and they should be aware to shut off the unnecessary loads. A ‘Bright Display Energy Meter (BDEM)’, when fitted indoor, will aware the consumers for...
When information exchange occurs between people via a network, then authentication and security of data have more priority. This paper introduces a low cost, handheld, wireless electronic notice board by using Atmel's ATmega32 microcontroller and different wireless technologies (Bluetooth and ZigBee) and their performance analysis based on the parameter such as range, BER (bit error rate), RSSI (Received...
This paper basically provides a real time model of a low cost wheel chair based on the guiding movement of the retina, for the persons disabled with quadriplegia. This model is expected to benefit the poor paralyzed people as it provides a simplified low cost model of the wheel chair. The model is realized through matlab in serial communication with the special purpose microcontroller IC manufactured...
The 89S52 microcontroller (MCU) is very popular among the students, teachers, amateurs, engineers, scientists, and hobbyists for building electronics projects and consumer products. Successful realization of MCU based products depends on the sound understanding of architecture, instruction and interfacing of the MCU, which can be effectively acquired with the help of a ‘Microcontroller Learning System...
This paper presents a hardware application based on MSP430 microcontroller and one wire protocol. In this paper, the two devices, one a master and other a slave are communicating via one wire bus. The microcontroller used is sniffing data between the devices and transmitting it using UART via RS232 serial communication to the same system or other PC and logging the data in excel format.
This work present new approach eye tracking with very less expensive IR sensor & IR led based apparatus connected to the computer. Photodiode & phototransistor are light reflection based component, the system design by use these components can be called as light reflection based system or non-imaging sensor base system. Basically this system is having very low complexity & very low computational...
This paper proposes an advanced industrial controller prepared for hazardous industrial environments, namely natural gas odorisation. Its design and conception is focused on robustness and reliability, with high flexibility to allow local and remote monitoring and control. Instead of a centralized approach, where the computational load relies on a unique processor, we propose a distributed architecture,...
Subway station (hereinafter referred to as station) is composed of main module and extended module, this article is mainly to the design of extension module. The extension module adopts the STM32F107VCT6 single-chip microcomputer based on the ARM architecture control buttons scanning and the LED bright, then transmitting to the main module which is in A8 core control ARM board, whose communication...
Angkutan Kota (angkot) is one of public transport that often used by citizen in Bandung. But, there's still a lot of citizen that use private vehicle instead of using public transportation like angkot. This is due to the services provided by public transport hasn't been satisfactory. Therefore, to improve the service of angkot, angkot's payment system should be improved by making a payment standard...
In this work a review of the more outstanding contributions, carried out in the automatic control context, that deal with the trajectory tracking task in autonomous wheeled mobile robots (WMR) by using an embedded system is presented. In this direction, with the intention of describing an embedded system, some definitions of such a system and also the parts integrating it are introduced. The contributions...
Sensor nodes are used extensively in order to gather real-time information in the social environment and natural environment. The production volume of sensor nodes is much increased with the development of cyber-physical systems. Therefore, it becomes important how to reduce the power consumption of huge sensor nodes. In this paper, the normally-off MCU architecture and the power management method...
