Myself HARSHITA TIWARI, B.TACH FINAL YEAR student and i want more information about the project named speed control of radiator fan using differential gear arrangement. I know only the basics related to this topic but i don't know that how to make a working model of above topic and how much cost is associated with this task.... ....etc

i want document about this project
Abstract ⎯ This paper has a background of SMMD (Single
Media Multi Device) control technology for causing various
actual feeling effects about one media source. SMMD technology
adds metadata controlling arbitrary multiple devices in one
MPEG-4 media. A home server produces a control command
from metadata and delivers control message to a sensory effect
device using the ZigBee communication. A device produces an
internal interface command or specific IR code for controlling an
actual feel ....etc

fan speed control system
INTRODUCTION
Fan Tachometer
The embedded controller registers 0x84 (LSB), 0x85 (MSB) are the main fan tachometer, and report fan speed in RPM in everything since the A31 and maybe a little earlier. Not much is know about the tachometer in earlier models, or even whether they had one or not.
On the X61/X61s, one must select through EC register 0x31 bit 0 which fa ....etc

DC Fan Speed Control PWM Signal Introduction
1. Speed Control Fan Structure
1-1. Use ON/OFF contr
Advantage：
Easy design and control method
Price cheaper
Disadvantage :
I. Power Dissipation is a design issue.
II. Not use friendly.
2. What is PWM Signal ?
PWM(Pulse Width Modulation): It’s a fixed frequency and pulse modulated for fan speed control.
Whenever change the duty cycle, the fan speed will be changed by system requirement

Circuit Generates Analog Fan-Speed Control


Abstract:
A linear circuit measures temperature and controls the speed of a cooling fan by generating a variable supply voltage for the fan. Fan noise is becoming a larger issue as more electronic equipment enters the office and the home. A variable speed fan permits slower, and quieter, fan speed when temperature conditions allow. Fan-control circuits range from simple switches that boost the fan speed at a certain temperature, to digitally controlled fans with ....etc
