CHAPTER I ------------------------------------------------- INTRODUCTION 1.1 Introduction Portable electronic devices are very popular nowadays. As the usage of these portable electronic devices is increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless

Thinking for a Change Origins The “Thinking Processes” originated from the Theory of Constraints‚ the ideas for process improvement developed by Elyahu Goldratt. He realized that he was becoming a bottleneck in the dissemination of the ideas behind the Theory of Constraints. The Thinking Processes are a set of tools and heuristics that Goldratt uses. The Theory of Constraints’ process optimisation technique “The 5 focusing steps” is easily applied to physical‚ logistical processes like manufacturing
