Choosing the fabric according to the quality is a I. INTRODUCTION challenging task. Monitoring the weaving machine by the manual method is difficult if the unit of The layers of warp yarn, and each pick of weft production machine count is high.

The density of the on the problem of producing a woven fabric, and material produced is determined by the fabric there are definite cycles during which certain ideas structure. The vision system consists of a web camera are reawakened and brought to the front and seen as and a micro-computer and allows to determine the something completely new. There are not enough geometric dimensions of the intervals between the weavers in the industry, and the in-take of new basic yarns of the fabric. The management of these recruits is not enough. Wages in the fabric industry dimensions provides an opportunity to control the have changed a great deal since the war and this has density of the manufactured fabric. The described increased the wages of the weaving (related to system makes it possible to automate the quality surgery). Manufacturers are getting a very much control of the loom. better price for the cloth which they produce, and M. W. Burton and J.S.

This project proposes an embedded system for Michael bailey and van kuren (2002) Power loom Control. The proposed system mainly Automation can be used to supplement the manual concentrates on monitoring the thread condition on processing of used electronic products in order to both vertical and horizontal bunch of thread. offset the increasing volumes in electronic waste Depending on the condition of thread in the power streams. The application of automation to loom weaving machine get shut down. This chapter demanufacturing requires high levels of flexibility. In deals with the Block diagram of the project and order to study the utility of automation for details of each hardware component chosen in such a demanufacturing of used products, a flexible cover way that it suits best for the design of the proposed removal process was implemented within an automated system. demanufacturing work cell. The process demonstrates two of the key objectives in automated processing of A. Block Diagram used products: feature identification and connection Figure 1 shows the block diagram of Power removal.

Jürgen Freudenberger et al (2001) have proposed convolutional and block encoding schemes which are variations of woven codes with outer warp. We propose methods to evaluate the distance characteristics of the considered codes on the basis of the active distances of the component codes. With this analytical bounding technique, we derived lower bounds on the minimum (or free) distance of woven convolutional codes, woven block codes, serially concatenated codes, and woven turbo codes. Next, we show that the lower bound on the minimum distance can be improved if we use designed interleaving with unique permutation functions in each row of the warp of the woven encoder. Finally, with the help of simulations, we get upper bounds on the minimum distance for some particular codes and then investigate their performance in the Gaussian channel.
