IEEE 2013: Indoor Localization on Mobile Phone Platforms Using Embedded Inertial Sensors  

IEEE 2013 Transactions on Navigation and Communication 

Abstract—Indoor localization techniques are commonly based on measuring the Wi-Fi received signal strength (RSS) and the method of "fingerprinting". The accuracy depends on density of recorded fingerprints in the radio map (RM) database. Building and updating RM is expensive and labour-intensive. Taking advantage of ubiquity of smart phones with embedded inertial sensors yields an economic and easy-to-deploy indoor localization system. In this work, the accelerometer and digital compass are used to recognize the user’s dynamic activities and walking directions. And the particle filter integrates the building map constraints and inertial measurements to estimate user’s location. On this basis, an indoor localization system with no dense wireless site survey requirements is proposed and evaluated.


IEEE 2013: Low Power Wireless Sensor Network for Building Monitoring

IEEE 2013 Transactions on Sensors Journal

Abstract—A wireless sensor network is proposed for monitoring buildings to assess earthquake damage. The sensor nodes use custom-developed capacitive micro electromechanical systems strain and 3-D acceleration sensors and a low power readout application-specified integrated circuit for a battery life of up to 12 years. The strain sensors are mounted at the base of the building to measure the settlement and plastic hinge activation of the building after an earthquake. They measure periodically or on-demand from the base station. The accelerometers are mounted at every floor of the building to measure the seismic response of the building during an earthquake. They record during an earthquake event using a combination of the local acceleration data and remote triggering from the base station based on the acceleration data from multiple sensors across the building. A low power network architecture was implemented over an 802.15.4 MAC in the 900-MHz band. A custom patch antenna was designed in this frequency band to obtain robust links in real-world conditions. The modules have been validated in a full-scale laboratory setup with simulated earthquakes.

IEEE 2013: Real-time swimmers' feedback based on smart infrared (SSIR) optical wireless sensor

IEEE 2013 Transactions on Systems Conference

Abstract—An IrDA link based on a serial infrared transceiver has been designed and implemented for real-time swimmers’ feedback. A wrist-mounted accelerometer provided stroke information to the transmitter. The signal was detected using a photodiode detector. Both the transmitter and receiver units measured 27 × 19 mm. Propagation experiments in air and under water were performed in a glass tank (91 × 39 × 45 cm) to validate the system. The maximum link length in air was 2 m and in still water 70 cm. In water with bubbles, the range reduced to 50 cm. This distance is sufficient for wrist–head communications during swimming. The information transmitted was the time duration of one complete stroke, which was updated every stroke and presented to the swimmer using an RGB LED mounted on the goggles. The hardware, software and implementation methods for the IrDA system are described.

IEEE 2013: Use of Ultrasonic Signal Coding and PIR Sensors to Enhance the  Sensing Reliability of an Embedded Surveillance System

IEEE 2013 Transactions on Systems Conference 

Abstract—In this paper we design and implement an embedded surveillance system by use of ultrasonic signal coding of ultrasonic sensors with multiple pyroelectric infrared sensors (PIR) to detect an intruder in a home or a storehouse. The PIR sensors are placed on the ceiling, and the ultrasonic sensor module consists of a transmitter and a receiver which are placed in a line direction; however, ultrasonic sensors with the same frequency are subject to interference by crosstalk with each other and have a high miss rate. To overcome these disadvantages of the ultrasonic sensor, our design reduces the miss rate from the environmental interference by using an ultrasonic coding signal. Both ultrasonic sensors and PIR sensors are managed by the majority voting mechanism (MVM).

IEEE 2013: Intelligent Household LED Lighting System Considering Energy Efficiency and User Satisfaction

IEEE 2013 Transactions on Consumers Electronics

Abstract — Saving energy has become one of the most important issues these days. The most waste of energy is caused by the inefficient use of the consumer electronics.  Particularly, a light accounts for a great part of the total energy consumption. Various light control systems are introduced in current markets, because the installed lighting systems are outdated and energy-inefficient. However, due to architectural limitations, the existing light control systems cannot be successfully applied to home and office buildings.  Therefore, this paper proposes an intelligent household LED lighting system considering energy efficiency and user satisfaction. The proposed system utilizes multi sensors and wireless communication technology in order to control an LED light according to the user’s state and the surroundings.  The proposed LED lighting system can autonomously adjust the minimum light intensity value to enhance both energy efficiency and user satisfaction. We designed and implemented the proposed system in the test bed and measured total power consumption to verify the performance. The proposed LED lighting system reduces total power consumption of the test bed up to 21.9%

IEEE 2012: Traffic Management for Automated Highway Systems Using Model-Based Predictive Control


Abstract—We present an integrated traffic management and control approach for automated highway systems (AHS). The AHS consist of interacting roadside controllers and intelligent vehicles that are organized in platoons with short intraplatoon distances and larger distances between platoons. All vehicles are assumed to be fully automated, i.e., throttle, braking, and steering commands are determined by an automated onboard controller. The proposed control approach is based on a hierarchical traffic control architecture for AHS, and it also takes the connection and transition between the nonautomated part of the road network and the AHS into account. In particular, we combine dynamic speed limits and lane allocation for the platoons on the AHS highways with access control for the on-ramps using ramp metering, and we propose a model-based predictive control approach to determine optimal speed limits and lane allocations, as well as optimal release times for the platoons at the on-ramps. To illustrate the potential of the proposed traffic control method, we apply it to a simple simulation example.

IEEE 2012: Building Lighting Automation through the Integration of DALI with Wireless Sensor Networks


Abstract — This paper focuses on the integration of Digital Addressable Lighting Interface (DALI) devices in wireless sensor networks. Since different manufacturers usually deal with one aspect of building automation - e.g. heating ventilation and air conditioning, lighting control, different kinds of alarms, etc. - final building automation system has different subsystems which are finally taken to an integrated building management system. The cost of this process is consequently increased due to additional hardware investment. Our main purpose is to provide the end consumer with an economical fully centralized system in which home appliances are managed by an IEEE 802.15.4-based wireless sensor network. Not only is it necessary to focus on the initial investment, but maintenance and energy consumption costs must also be considered. This paper explains the developed system along with a brief introduction to usual building automation protocols. Finally it presents future work in this field1.

IEEE 2012: Minimum Fuel Control Strategy in Automated Car-Following Scenarios


Abstract—Fuel consumption of traditional ground vehicles is significantly affected by how the vehicles are driven. This paper focuses on the servo-loop control design of a Pulse-and-Gliding (PnG) strategy to minimize fuel consumption in automated car following. A switching-based framework is proposed for real-time implementation. The corresponding controller was synthesized for ideal conditions and subsequently enhanced to compensate for practical factors such as powertrain dynamics, speed variations, and plant uncertainties. Simulations in both uniform and naturalistic traffic flows demonstrate that, compared with a linear quadratic (LQ)-based benchmark controller, the PnG controller improves fuel economy up to 20%. The significant fuel saving is achieved while maintaining precise range bounds so that the negative impact on safety/traffic flow is contained. The developed algorithm can potentially be embedded in adaptive cruise control systems to achieve fuel-saving function.

IEEE 2012: An Open Traffic Light Control Model for Reducing Vehicles’ CO2 Emissions Based on ETC Vehicles


Abstract—Usually, vehicles’ stop-and-go driving will consume more fuel and emit more CO2 than constant speed driving. To reduce vehicles’ CO2 emissions, vehicles’ travel should be smoothed by reducing the stop-and-go times. In this paper, a threetier structure is proposed to realize dynamic traffic light control for smoothing vehicles’ travel. In tier-1, an electronic toll collection (ETC) system is employed for collecting road traffic flow data and calculating the recommended speed. In tier-2, radio antennas are installed near the traffic lights. Road traffic flow information can be obtained by wireless communication between the antennas and ETC devices. In tier-3, a branch-and-bound-based real-time traffic light control algorithm is designed to smooth vehicles’ travels. After smoothing vehicles’ travels, more vehicles can pass intersections with less waiting time and fewer short-time stops; therefore, the vehicles’ CO2 emissions can be reduced. Simulation results indicate that the proposed scheme performs much better than the adaptive fuzzy traffic light control method: The average waiting time, short-time stop times, and CO2 emissions are greatly reduced, and the nonstop passing rate is greatly improved.

IEEE 2012: Design and Realization of a Framework for Human–System Interaction in Smart Homes


AbstractThe current smart home is a ubiquitous computing environment consisting of multiple autonomous spaces, and its advantage is that a service interacting with home users can be set with different configurations in space, hardware, software, and quality. As well as being smart technologically speaking, a smart home should also never forget to retain the “home nature” when it is serving its users. In this paper, we first analyze the relationship among services, spaces, and users, and then we propose a framework as well as a corresponding algorithm to model their interaction relationship. Later, we also realize the human–system interaction framework to implement a smart home system and develop “pervasive applications” to demonstrate how to utilize our framework to fulfill the human-centric interaction requirement of a smart home. Finally, our preliminary evaluations show that our proposed work can enhance the performance of the human–system interaction in a smart home environment.

IEEE 2012: New Real-Time Structural Health Monitoring Micro system for Aircraft Propeller Blades


Abstract --- Blade Brief History - Blades are sophisticated requiring high engineering performance in terms of aerodynamics and mechanical design. Archimedes was the first to build an ancestor to the propeller when he constructed a screw for lifting water. Nineteen centuries later, the air screw was developed by Leonardo Da Vinci, who envisioned its use in a rudimentary helicopter. It was not until 1 884 that mechanically controlled flight arrived on the scene: the airship "La France " was powered by an electric motor and a 1-meter propeller. The first controlled "heavier-than-air " airplane was constructed by the Wright brothers in 1 903 ; they understood that a blade is like a twisted wing. The aeronautics industry was soon born and the number of aircraft types quickly multiplied. Made of wood or metal, blade enhancements were developed to increase performance in air battles: in-flight adjustable and reversible pitch, and electrical blade de-icing. In the last ten years, more noticeable innovation was the development of composite structures: new Airbus A400M is propelled by four 8-blade composite propellers which counter-rotate (i.e., on the same wing, each propeller rotates in opposite directions). Today propellers are used almost exclusively by small planes or special purpose aircraft like the A400M. Yet  project will enable the subsequent development of a real-time blade monitoring system.

IEEE 2012: An Intelligent V2I-Based Traffic Management System


AbstractVehicles equipped with intelligent systems designed to prevent accidents, such as collision warning systems (CWSs) or lane-keeping assistance (LKA), are now on the market. The next step in reducing road accidents is to coordinate such vehicles in advance not only to avoid collisions but to improve traffic flow as well. To this end, vehicle-to-infrastructure (V2I) communications are essential to properly manage traffic situations. This paper describes the AUTOPIA approach toward an intelligent traffic management system based on V2I communications. A fuzzy-based control algorithm that takes into account each vehicle’s safe and comfortable distance and speed adjustment for collision avoidance and better traffic flow has been developed. The proposed solution was validated by an IEEE-802.11p-based communications study. The entire system showed good performance in testing in real– world scenarios, first by computer simulation and then with real vehicles.

IEEE 2012: PN-WSNA-Based Eye–Hand–Leg Coordination with a FIRA HuroCup Basketball Game


AbstractBiped humanoid robots present perception and locomotion capabilities similar to those of human beings. Eye–hand–leg coordination is a basic and required capability for a healthy person, and eye—hand–leg coordination performs various skilloriented tasks. In this paper, the skill-oriented tasks for playing a basketball game were implemented for a child-size humanoid robot (HuroEvolution) through the use of eye–hand–leg coordination. The “eye” function is responsible for active perceptions in environments, the “hand” function is for gripping and manipulating objects to perform specific tasks, and the “leg” function is used to transport the biped robot to a desired location for the execution of tasks. Coordination among the eye, hand, and leg was achieved using predefined scenarios for various skill-oriented tasks. To utilize flexible and systematic skill-oriented task implementations, a Petri net-based wireless sensor node architecture (PN-WSNA) was employed in this project to define the task scenarios. The control scenario of eye–hand–leg coordination was realized by aggregating fundamentalPN-WSNAscenario modules for fast realizations.The coordination model can be further evaluated theoretically to investigate its propensity for avoiding system deadlocks. Finally, the skill-oriented eye–hand–leg coordination tasks for realizing the Federation of International Robot-Soccer Association HuroCup League basketball games were successfully demonstrated to validate our approaches.

IEEE 2008: A Biometric-Secure e-Voting System for Election Processes


Abstract: In this paper we propose a multifaceted online e-voting system. The proposed system is capable of handling electronic ballots with multiple scopes at the same time, e.g., presidential, municipal, parliamentary, amongst others. The system caters for integrity of an election process in terms of the functional and non-functional requirements. The functional requirements embedded in the design of the proposed system warrant well-secured identification and authentication processes for the voter through the use of combined simple biometrics. The design of the system guarantees that no votes in favor of a given candidate are lost, due to improper tallying of the voting counts, with the proper incorporation of system FLAG’s. Transparency of voting follows through in all phases of an election process to assure the voter that his/her vote went in favor of his/her candidate of choice. Besides its main functional properties, the proposed system is designed to cater for several essential nonfunctional requirements. Of utmost importance are the requirements for correctness, robustness, coherence, consistency, and security. To verify the robustness and reliability of the proposed system, intensive computer simulations were run under varying voting environments, viz. voter density, voter inter-arrival times, introduced acts of malice, etc. Results of the simulations show that security and performance of the system are according to  expectations. These results provide the proper grounds that would guide the decision maker in customizing the proposed system to fit his particular voting need.

The low-power PIR detectors take advantage of pyroelectricity to detect a human body that is a constant source of Passive Infrared (radiation in the infrared region). The system senses the signal generated by PIR sensor detecting the presence of individuals not at thermal equilibrium with the surrounding environment. Detecting the presence of any unauthorized person in any specific time interval, it triggers an alarm & sets up a call to a predefined number through a GSM modem. This highly reactive approach has low computational requirement, therefore it is well-suited to surveillance, industrial applications and smart environments. Tests performed gave promising results.

IEEE 2011: Design of Auto-guard System Based on RFID and Network


AbstractTo reduce the theft rate of the car and meet the intellectualized auto-guard demand of people,we proposed an auto-guard system which combined the radio frequency identify technology and the global mobile communication network. The system took Texas Instruments Company's car-used microcontroller STM8AF51AA as the control core.NXP Semiconductors Company's radio reader IC MF RC522 could identify the car owner quickly and then realized the function of keyless entry and keyless start-up. At the same time. The infrared sensors and vibration sensors completed the monitoring function.GSM module SIM300DZ of Simcom company finished setting and dismissing the prevention of message or call and controlled the car’s states remotely through AT instructions.It has showed in practice that compared with the traditional autoguard system,this system could not only identify the owner singly,but also improve the security and reliability.So it has achieved the unity between intellectualized safeguard and remote control.



ABSTRACT: Every year thousands of people die because of earthquake occurs in a dangerous place or during a defenseless sleep. Here’s a GSM-based seismic alert system that could warn before an earthquake strikes. Earthquakes strike without warning. The resulting damage can be minimized and lives can be saved if people living in the earthquake-prone area are already prepared to survive the strike. This requires a warning before strong ground motion from the earthquake arrival. Such a warning system is possible because of energy wave released at the epicenter of the earth quake travels slower than light. The warning signal from the earthquake epicenter can be transmitted to different places using satellite communication network, fiber-optics network, pager service, Cell phone services or a combination of these. The satellite-based network is ideal when an alert system has to cover a large country like India. For earthquake-prone states like Gujarat, a seismic alert system using the global system for mobile communication network spread throughout the state is proposed here. This system does not try to find the epicenter or fault line caused by the earthquake. It simply monitors the earth vibrations and generates alert signal when the level of earth vibrations crosses a threshold.

IEEE 2011 : Design and Implementation of a Home Embedded Surveillance System with Ultra-Low Alert Power


Abstract In this paper we design and implement a home embedded surveillance system with ultra-low alert power. Traditional surveillance systems suffer from an unnecessary waste of power and the shortcomings of memory conditions in the absence of invasion. In this design we use Pyroelectric Infrared sensors (PIR) and pressure sensors as the alert group in windows and doors where an intruder must pass through. These low-power alert sensors wake up the MCU (Micro Controller Unit) which has power management for the ultrasonic sensors and PIR sensors indoors. This state transition method saves a large number of sensors required for the alert power. We also use the Majority Voting Mechanism (MVM) to manage the sensor groups to enhance the probability of multiple sensors sensing. After the  MCU sends the sensor signals to the embedded system, the program starts the Web camera. Our sensing experiment shows that we reduce the system’s power consumption1.

In the both systems, each customer has to collect a token and then will be served whenever the token number is displayed. The systems were designed around a 16F72 IC, a low-cost 8-bit PIC microcontroller and entirely software controlled. The control programs have been developed using the PIC assembly language. Finally, the systems have been tested under different conditions to evaluate their performance.

IEEE 2011 : A Microcontroller-Based Multi-Function Solar Tracking System


Abstract— Renewable energy solutions are becoming increasingly popular. Photovoltaic (solar) systems are but one example. Maximizing power output from a solar system is desirable to increase efficiency. In order to maximize power output from solar panels, one needs to keep the panels aligned with the sun. As such, a means of tracking the sun is required. This is definitely a more cost effective solution than purchasing additional solar panels. It has been estimated that the yield from solar panels can be increased by 30 to 60 percent by utilizing a tracking system instead of a stationary array. In this paper, a prototype for a micro controller-based Multi-function solar tracking system is described, which will keep the solar panels aligned with the sun in order to maximize efficiency. The maximum power point tracking (MPPT) data can be transmitted in real time to other solar systems in need of this data.

IEEE 2011 : More Efficient Home Energy Management System Based on ZigBee Communication and Infrared Remote Controls


Abstract This paper describes more efficient home energy management system to reduce power consumption in home area. We consider the room easily controllable with an IR remote control of a home device. The room has automatic standby power cut-off outlets, a light, and a ZigBee hub. The ZigBee hub has an IR code learning function and educates the IR remote control signal of a home device connected to the power outlet. Then the power outlets and the light in the room can be controlled with an IR remote control. A typical automatic standby power cut-off outlet has a waiting time before cutting off the electric power. It consumes standby power during that time. To eliminate the waiting time, we turn off the home device and the power outlet simultaneously with an IR remote control through the ZigBee hub. This method actively reduces the standby power. The proposed HEMS provides easy way to add, delete, and move home devices to other power outlets. When a home device is moved to the different outlet, the energy information of the home device is kept consistently and seamlessly regardless of location change.The proposed architecture gives more efficient energy-saving HEMS1.

IEEE 2010: Vision-Based Automated Parking System]

10th International Conference on Information Science, Signal Processing and their Applications (ISSPA 2010)

Abstract - This paper describes an approach to overcome a situation of monitoring and managing a parking area using a vision based automated parking system. With the rapid increase of cars the need to find available parking space in the most efficient manner, to avoid traffic congestion in a parking area, is becoming a necessity in car park management. Current car park management is dependent on either human personnel keeping track of the available car park spaces or a sensor based system that monitors the availability of each car park space or the overall number of available car park spaces. In both situations, the information available was only the total number of car park spaces available and not the actual location available. In addition, the installation and maintenance cost of a sensor based system is dependent on the number of sensors used in a car park. This paper shows a vision based system that is able to detect and indicate the available parking spaces in a car park. The methods utilized to detect available car park spaces were based on coordinates to indicate the regions of interest and a car classifier. This paper shows that the initial work done here has an accuracy that ranges from 90% to 100% for a 4 space car park. The work done indicated that the application of a vision based car park management system would be able to detect and indicate the available car park spaces

In this paper, the equivalent models of each mode and complete design considerations are all detailed. All the experimental results are used to demonstrate the feasibility.

IEEE 2009: Design Of Intelligent Traffic Light Controller Using Embedded System

ABSTRACT : Present Traffic Light Controllers (TLC) are   based on microcontroller and microprocessor. These TLC   have limitations because it uses the pre-defined hardware, which is functioning according to the program that does not have the flexibility of modification on real time basis. Due to the fixed time intervals of green, orange and red signals the waiting time is more and car uses more fuel. To make traffic light controlling more efficient, we exploit the emergence of new technique called as “Intelligent traffic light controller”. This makes the use of Sensor Networks along with Embedded Technology. The timings of Red, Green lights at each crossing of road will be intelligently decided based on the total traffic on all adjacent roads. Thus, optimization of traffic light switching increases road capacity and traffic flow, and can prevent traffic   congestions. GSM cell phone interface is also provided for users   those who wish to obtain the latest position of traffic on congested roads. This is a unique feature of this project which is very useful to car drivers to take an alternate route in case of congestion. The various performance evaluation criteria are average waiting time, average distance traveled by vehicles, switching frequency of green light at a junction, efficient emergency mode operation and satisfactory operation of SMS using GSM Mobile. The performance of the Intelligent Traffic light Controller is compared with the Fixed Mode Traffic Light Controller. It is observed that the proposed Intelligent Traffic Light Controller is more efficient than the conventional controller in respect of less waiting time, more distance traveled by average vehicles and efficient operation during emergency mode and GSM interface. Moreover, the designed system has simple architecture, fast response time, user friendliness and scope for further expansion. Keywords: Intelligent Traffic Light Controller, embedded system, Performance Evaluation, Microcontroller based system.
