To study engineering can be difficult, especially transforming theoretical knowledge into practice. To address this issue, Otto and Wood have developed a reverse engineering and redesign methodology, suggesting that it can be used as a tool in the process of learning mechanical engineering and design. The aim with this report is to evaluate this statement, emphasizing on the reverse engineering process and evaluating its usefulness as an educational tool. In order to fully understand the process, two cordless screwdrivers will be reverse engineered, functioning as an example throughout the report. A theoretical background of the process will be introduced, including descriptions concerning the different steps and their encompassed tools, tests and methods. Trough the implementation, the screwdrivers
are disassembled, analysed and experienced, resulting in a clear product specification with information of components and product functions. One example is the assembly plan, were the product structure is presented as two sub assemblies with “layer on layer” assembly. Another result of the implementation is that the reverse engineering process was experienced in reality, exposing the required modifications necessary in order to function as an educational tool. The main issue for the process is its focus on
customer needs instead of product focus. Therefore, it is suggested that a new reverse engineering process based on the existing one should be developed, focusing more on the product and less on the customer to better suit an educational purpose.

Power harvesting, energy harvesting, power scavenging, and energy scavenging are four terms commonly used to describe the process of extracting useful electrical energy from other ambient energy sources using special materials called transducers that have the ability to convert one form of energy into another. While the words power and energy have vastly different definitions, the terms “power harvesting” and “energy harvesting” are used interchangeably throughout much of the literature to describe the same process of extracting electrical energy from ambient sources. Even though most of the energy coupling materials currently available have been around for decades, their use for the specific purpose of power harvesting has not been thoroughly examined until recently, when the power requirements of many electronic devices has reduced drastically.

Abstract:- Intelligent Energy Saving System can be used in places like where lighting is very important. The libraries will be well illuminated with many lamps. When people are not present at a reading place the lighting can be made OFF and when they are present, the lighting made ON. All these can be done through by Dimming circuit and PIR sensor.

If a person entering to the monitored area, the PIR sensors activates and sense the person, gives to the micro controller. The Infrared energy emitted from the living body is focused by a Fresnel lens segment. Then only the PIR sensor activates. After sensing the person LDR checks the light intensity of the monitored area, whether it is bright or dark. Depending on the LDR output, the lamp may be ON / OFF by using Dimmer circuit.

By using this system we can adjust the speed of Fan according to the room temperature measured by Thermostat, which is connected to the micro controller.

To display the room temperature of PIR mode operation we are using the LCD display.

We present a high-speed, clockless, serial link transceiver for inter-chip communication in asynchronous VLSI systems. Serial link transceivers achieve high offchip data rates by using multiplexing transmitters and demultiplexing receivers that interface parallel on-chip data paths with high-speed, serial off-chip buses. While synchronous transceivers commonly use multi-phase clocks to control the data multiplexing and demultiplexing, our clockless transceiver uses a token-ring architecture that eliminates
complex clock generation and synchronization circuitry.Furthermore, our clockless receiver dynamically self-adjusts its sampling rate to match the bit rate of the transmitter. Our SPICE simulations report that in a 0.18-m CMOS technology this transceiver design operates at up to 3-Gb/s and dissipates 77 mW of power with a 1.8-V supply voltage.

The mobility of military vehicles plays a key role in operation. The ability to reach the desired area in war theater presents the most important condition for a successful accomplishment of the mission for military vehicles. The off road vehicles face a broad spectrum of terrains to cross. These terrains differ by geometry and the soil characteristics.
NATO References Mobility Model (NRMM) software is based on empirical
relationship between the terrain characteristics, running conditions and
vehicles design. The paper presents the main results of a comparative mobility analysis for M1 and HMMWV vehicles obtained using NRMM.

This thesis investigates the design of a vision system for the "Guroo" a robot humanoid soccer
player. The aim was to create a vision system that was able to view and track objects in the
three dimensional world. Vision hardware is presented for the CMOS Digital Camera and
Interface software for a field programmable gate array included on the main vision board.
The design and implementation of an aesthetically pleasing head is also presented.
Beginning in 2000 the project has moved on from the development of the design of the
original vision system for the "Viperoo" robot soccer team to designing a new system for the
use in the Guroo project and the 2001 upgrade for the Viperoos small soccer league.
The major achievements in the redesign of the vision system are the use of the OV7620
CMOS digital camera chip which has trebled the frame rate of the digital camera used and
the implementation of a dual port ram system for the field programmable gate array. These
combine with the developments in the vision board to produce an improved local vision
system.
The result of this development was a camera that passed data from the three dimensional
world surrounding it to the main vision board.
Future work on the design of a vision system will involve optimising the vision code and
low level hardware code. Future students could also port areas of the object detection code
to the field programmable gate array as another area of vision development.on development.

Routers are probably the most important component of a NoC, as the performance of the whole network is driven by the routers’ performance. Cost for the whole network in terms of area will also be minimised if the router design is kept small. A new application specific processor architecture for implementing NoC routers is proposed in this master thesis, which will be called μNP (Micro-Network Processor). The aim is to offer a solution in which there is a trade-off between the high performance of routers implemented in hardware and the high level of flexibility that could be achieved by loading a software that routed packets into a GPP. Therefore, a study including the design of a hardware based router and a GPP based router has been conducted. In this project the first version of the μNP has been designed and a complete instruction set, along with some sample programs, is also proposed. The results show that, in the best case for all implementation options, μNP was 7.5 times slower than the hardware based router. It has also behaved more than 100 times faster than the GPP based router,keeping almost the same degree of flexibility for routing purposes within NoC.

Abstract :- An electrical energy meter measures and records electrical power consumed over time by electrical appliance. Energy meter can be electromechanical or electronic-based, and it can be deployed in domestic or industrial environment. However, electromechanical meters have been with us for a very long time, it is of late that electronic meters start to appear in electrical metering scene. The manual reading of electromechanical meter for the purpose of billing is fraught with many social and management problems. This paper presents a simple automatic smart device developed to automate the process of remote meter reading, remote-billing, and remote disconnection, in case of defaulting in payment, of existing electromechanical energy meter without modification.
