This paper presents a tested research concept that implements a complex evolutionary algorithm, genetic algorithm (GA), in a multi-microcontroller environment. Parallel Distributed Genetic Algorithm (PDGA) is employed in adaptive beam forming technique to reduce power usage of adaptive antenna at WCDMA base station. Adaptive antenna has dynamic beam that requires more advanced beam forming algo...

In recent years, microcontrollers have been used in many areas. Implementation of a circuit by using several discrete analog and digital devices can be done using only one microcontroller. However, industrial microcontrollers have limited resources to implement complex mathematical functions, such as Taylor series. In this work, implementation of Taylor series on a PIC microcontroller is given....

Given energy as the limiting factor in a low-power battery-driven embedded microcontroller (MCU), energy-efficient operation is critical. Low-energy microcontrollers benefit from comparable performance and longer lifetimes when compared to microcontroller cores without energy saving schemes. Dynamic voltage and frequency scaling (DVFS) has been proposed in [1] as a novel technique to provide op...

This paper describes the development of a heart rate monitor system based on a microcontroller. It offers the advantage of portability over tape-based recording systems. The paper explains how a single-chip microcontroller can be used to analyse heart beat rate signals in real-time. In addition, it allows doctors to get the heart beat rate file of the patient by email every twenty four hours. I...

A new solution of a smart microcontroller sensor based on a simple direct sensor-microcontroller interface for technical objects modeled by two-terminal networks and by the Beaunier’s model of anticorrosion coating is proposed. The tested object is stimulated by a square pulse and its time voltage response is sampled four times by the internal ADC of microcontroller. A neural classifier based o...

The design of a microcontroller based pacemaker tester is presented in this paper. Both invasive and noninvasive (transthoracic) pacemakers can be tested using this device. Two test loads are provided; a 500 ohms load for testing invasive pacemakers and a 50 ohms load for testing non-invasive pacemakers. A two line LCD display is used to indicate the test parameters, test results and the test i...

A dielectric constant measurement setup has been developed to measure dielectric constant of liquids using AT89C55WD microcontroller. A modified operational amplifier based AC Schering Bridge network is used to compute capacitance and hence calculate dielectric constant of liquids. This instrument system permits recording of dielectric constant of liquids at various concentrations and temperatu...

This project is developed with aims to improve home security systems available in current market. This project claims to produce a prototype camera and global system for mobile communication (GSM) interfacing system for home security surveillance. This system uses two sensors, namely ultrasonic and passive infrared receiver (PIR). The ultrasonic sensor is used to detect movement of objects and ...

Real-time microcontrollers have been widely adopted in cyber-physical systems that require both real-time and security guarantees. Unfortunately, security is sometimes traded for real-time performance in such systems. Notably, memory isolation, which is one of the most established security features in modern computer systems, is typically not available in many real-time microcontroller systems ...

This paper presents the development of imager block to be associated in a capsule endoscopy system. Since the capsule endoscope is used to diagnose gastrointestinal diseases, the imager block must be in small size which is comfortable for the patients to swallow. In this project, a small size 1.5V button battery is used as the power supply while the voltage supply requirements for other compone...
