ABSTRACT

Here, proposing a novel wireless access monitoring and control system based on the digital door lock, which is explosively used as a digital consumer device. Digital door lock is an electronic locking system operated by the combination of digital key, security password or number codes. This paper presents a prototype of the proposed system and shows a scheme for the implementation. To implement the system with ZigBee network protocol, four types of modules are developed, ZigBee module, digital door lock module, human ....etc

Introduction

People with severe speech and motor impairment due to cerebral palsy are great difficult to move independently and also cannot control home electric devices. Computer has much to offer people with disability, but the standard human-machine interface (e.g. keyboard and mouse) is inaccessible to this population. In this chapter, we describe a speech recognition interface for the control of powered wheelchair and home automation systems via ....etc

Abstract

This paper presents the design of a clap activated switch device that will serve well in different phono-controlled applications, providing inexpensive key and at the same time flee from false triggering. This involves the design of various sages consisting of the pickup transducer, low frequency, audio low power and low noise amplifier, timer, bistable and switches. It also consists of special network components to prevent false triggering and ensure desired performance objectives. A decade counter IC serves the bistable fu ....etc

A Simple Light activated switch

Description.
This is the circuit diagram of a light activated switch based on National Semiconductors comparator IC LM 311 and a LDR.

The circuit is based on a voltage comparator circuit wired around IC 1.The non inverting in put of IC1 is given with a reference voltage of 6V using resistors R3 and R4. The input to the inverting input will be the voltage across the LDR that is light dependent. At darkness the resistance of the LDR will be high and so do the voltage across it. At this condition the voltage ....etc
