ABSTRACT
The size and resolution of computer displays has increaseddramatically, allowing more information than ever to berendered on-screen. However, items can now be so small orscreens so cluttered that users need to lean forward toproperly examine them. This behavior may be detrimentalto a user’s posture and eyesight. Our Lean and Zoomsystem detects a user’s proximity to the display using acamera and magnifies the on-screen content proportionally.This alleviates dramatic leaning and makes items morereadable. Results from a user ....etc

PROXIMITY SENSORS FOR ROBOTS

ABSTRACT
In order to perform the task in a satisfactory way the robot must have certain humanlike senses and capabilities. These include vision and hand-eye coordination, touch and hearing. This is achieved by using sensors. The types of sensors used in robotics include vision, voice, tactile, proximity etc. proximity sensors measure the relative distance between the sensors and objects in the robot's environment. This sense keeps a robot from running into things. A proximity sensor is a sensor able to detect ....etc

The main aim of this project is to map the vehicles and find out the speed of the vehicles; this system uses GPS receiver/transmitter, GSM receiver/transmitter with a micro controller. Imagine the vehicle has left Bangalore at 6 o clock in the morning. If the officer in charge for that vehicle wants to know where this bus is, he will send an SMS to that particular bus number. The SMS, which has sent, by the officer will reach the vehicle, which is traveling and there it will compare the password and the command. If every thing matches then it w ....etc

Final Report on
Dual-Tone Multiple Frequency (DTMF) Detector Implementation
Presented By:
Giiner Arslan
for EE382C Embedded Software Systems
Abstract
Dual-tone Multi-frequency (DTMF) signals are used in touch-tone telephones as well as many other areas such as interactive control, telephone banking, and pager system. As analog telephone lines are converted to digital, researchers became interested in digital DTMF detectors.
There are many digital DTMF detecting algorithms, but most of them do not comply wit ....etc
