blinking a led using 8051 ppt

This is the first project regarding 8051 and of course one of the simplest, blinking LED using 8051. The microcontroller used here is AT89S51 In the circuit, push button switch S1, capacitor C3 and resistor R3 forms the reset circuitry. When S1 is pressed, voltage at the reset pin (pin9) goes high and this resets the chip. C1, C2 and X1 are related to the on chip oscillator which produces the required clock frequency. P1.0 (pin1) is selected as the output pin. When P1.o goes high the transistor Q1 is forward biase ....etc

accident prevention using eye blinking and head movement ppt

Abstract

This paper describes a real-time online prototype driver-fatigue monitor. It uses remotely located charge-coupled-device cameras equipped with active infrared illuminators to acquire video images of the driver. Various visual cues that typically characterize the level of alertness of a person are extracted in real time and systematically combined to infer the fatigue level of the driver. The visual cues employed characterize eyelid movement, gaze movement, head movement, an ....etc

I feel as though there are many individuals on this site who haven't had the opportunity to see what our customers are doing with our products . I know browsing through thread after thread to see results can be daunting, so I've gone ahead and collected photos from many various grow demonstrations that are either completed, near completion, or in progress to show you that the future of lighting technology is here!

Tele-Graffiti (A Camera-Projector Based RemoteSketching System with Hand-Based User Interface and Automatic Session Summarization)

Abstract

One way to build a remote sketching system is to use a video camera to image what each user draws at their site, transmit the video to the other sites, and display it there using an LCD projector. To make such a system usable, however, the users have to be able to move the paper on whic ....etc
