Using accelerometer and EMG signals to estimate arm motion

This study investigates a means to overcome this degradation through use of EMG signals combined with accelerometer signals to measure the upper arm static and dynamic acceleration. Both EMG signal and accelerometer inputs are fed into an artificial neural network. The artificial neural network continuously predicts arm movement trajectories. An offline time-delay Artificial Neural network (TDANN) is employed to predict the movement trajectories of the arm. The accuracy of prediction was judged by using a set of goniometer readings which provides the changes in the angles of the upper limb. All data was processed in the Matlab environment. The TDANN deployed was developed in the neural network toolbox present within the Matlab environment. The developed neural network was optimized and trained with different sets of inputs, and the results for each of the trails was noted. The results obtained clearly demonstrated that accelerometers are able to enhance pattern recognition and thus provide better prosthesis control. Neural Network Optimization and Prediction Performance The neural network structure used for the study is the TDANN. TDANN is a neural network architecture whose primary purpose is to function on continuous data. The major advantage of using TDANN on continuous data is its ability to adapt the network’s weights and activation function online by use of back propagation error method. ...

Using Roof Shingle for Asphalt Pavement
In addition it contains between 32% and 42% of a coating filler such as limestone followed by some 28% to 42% of granules. The remaining portion of asphalt shingles is composed of fiberglass, cotton rags, paper and adhesives (Carter, 2008). The use of asphalt is pervasive throughout shingle manufacturing and asphalt constitutes a major part of shingles. The large amount of asphalt present in roofing shingles make these shingles suitable for recycling applications such as for constructing roads. It is estimated that the United States alone manufactures around 12.5 billion square feet of asphalt...

Advantages of using solar cells
The environment has become a big issue around the whole world. During the last decade, it started to change quickly. The earth is becoming warmer and because of that, there are a lot of natural problems and disasters around the world.This is called global warming. People on earth caused this change in temperature. Further, people need energy in their daily lives. They need electricity, fire, hot water, heating and cooling. To produce energy that is enough for all of these activities, we need fossil fuels and coal. All the countries around the world use these two fuels to make electricity and...

home automation lightning motion sensor and zigbee wireless
Most presence detectors have an in-built light sensor (lux) that will turn off the lights if there is sufficient natural light. Regulating lights with a presence detector may save up to 65% of the total cost spent on lighting energy (CP Electronics, 2013). How the system works Presence detectors also known as PIR (Passive Infra-Red) work on a principle similar to that applied in motion detectors. These devices log the thermal radiations of their environments or area under detection. When thermal radiation in the area is detected, for example, in the case of a person coming close to the sensor,...

iris recognition system using principal component analysis
This gives a fine demarcation between the inter class and intra class irises and hence the recognition becomes easier. Principal component analysis has been used to reduce the dimensionality. This enables choice of appropriate features from the iris templates and improves classification. The iris recognition accuracy has been described in terms of False Reject Ratio and False Accept Ratio. Table of contents Chapter 1 – Introduction of Project 1.1. Introduction 1.2.

The feedback system is designed so well that it updates the status of input torque in fraction of a second and as a result exoskeleton keeps working accordingly; and works well with frequent torque changes. A heel pressure sensor is required that produces an electrical signal whenever heel touches the ground or force is sensed on the heels because of its interaction with the ground. Signal from this sensor helps in regulating the sequential movement of the exoskeleton. These force sensors are usually generated by making use of a couple of force sensors but in our design use of a simple...
