The Figure above depicts the longest flights made by various aircraft in the period 1890 to 1909. Green points

represent the various Wright craft during this period. Blue points represent non-Wright craft made between 1890 and

1905, while red points represent non-Wright craft made from 1906 to 1909. Lines on the graph are regression

functions. The flat blue line indicates that the field as a whole was making NO sustained progress through the end of

1905. This lack of progress is almost invariably true of individual inventors as well as the group as a whole. The

positive slope of the Wright brothers indicates a steady progression in the ability of their heavier-than-air craft. Once

details of the Wrights methods became public when their patent was issued in late 1905, other inventors quickly copied

the important discoveries of the Wright brothers, and developed airplanes as capable as those of the Wrights.

Excerpts from CNN online, reported by Michael Coren

Monday, October 4, 2004 Posted: 7:59 PM EDT (2359 GMT) Source:

MOJAVE DESERT, California (CNN) -- SpaceShipOne achieved its most spectacular flight yet,

climbing to an altitude of 377,591 feet (71 1/2 miles) to win the $10 million Ansari X Prize on Monday.

X Prize officials said it set an altitude record exceeding the military X-15's top altitude of 354,200 feet (67 miles) set on

August 22, 1963. With a wish of "Good luck and Godspeed," mission control sent the privately funded craft toward space for

the second time in a week, the requirements for winning the X Prize. "Today we have made history. Today we go to the stars,"

said Peter Diamandis, co-founder of the X Prize Foundation.The $10 million award is intended to spur civilian spaceflight.

The craft left a near perfect dovetail of exhaust contrails with the White Knight turbo jet, which carried it aloft, as its

rocket ignited for 84 seconds. The rocket burn sent SpaceShipOne on a trajectory that sent it climbing for almost a minute after

the engine shut down…….

Paul Allen, who financed the program, Richard Branson, who recently founded Virgin Galactic for space tourism, and Burt

Rutan greeted the newly minted astronaut on the runway. Brinnie's family also joined him on the podium.

Space ShipOne and White Knight, featured a new paint job promoting Virgin Galactic, Branson's new venture, which recently

announced a deal to license the SpaceShipOne technology for a fleet of commercial spacecraft

Winning the X Prize with SpaceShipOne is only the beginning for Rutan.

"I have a hell of a lot bigger goal now (than NASA)," he said.

This is the 2nd OSA (NTU) Student group Christmas gathering for our members. This

gathering is to show our gratitude to all the members and committee members for their hard

work put into the several activities since our formation last September 2003. The dinner was

held at Pear River Restaurant in Suntec City on 9 th December.

How do optical mice work?

Source: http://computer.howstuffworks.com/question631.htm

It appears that the venerable wheeled mouse is in danger of extinction. The now-preferred device for pointing and

clicking is the optical mouse.

This Microsoft Intellimouse uses optical

technology.

In this photo, you can see the LED on the bottom of the

mouse.

Developed by Agilent Technologies and introduced to the world in late 1999, the optical mouse actually uses a tiny

camera to take 1,500 pictures every second. Able to work on almost any surface, the mouse has a small, red lightemitting

diode (LED) that bounces light off that surface onto a complimentary metal-oxide semiconductor (CMOS)

sensor. The CMOS sensor sends each image to a digital signal processor (DSP) for analysis. The DSP, operating at

18 MIPS (million instructions per second), is able to detect patterns in the images and see how those patterns have

moved since the previous image. Based on the change in patterns over a sequence of images, the DSP determines

how far the mouse has moved and sends the corresponding coordinates to the computer. The computer moves the

cursor on the screen based on the coordinates received from the mouse. This happens hundreds of times each second,

making the cursor appear to move very smoothly.

Optical mice have several benefits over wheeled mice:

• No moving parts means less wear and a lower chance of failure.

• There's no way for dirt to get inside the mouse and interfere with the tracking sensors.

• Increased tracking resolution means smoother response.

• They don't require a special surface, such as a mouse pad.

Apple has transformed its optical mouse into

a modern work of art.

Although LED-based optical mice are fairly recent, another type of optical mouse has been around for over a decade.

The original optical-mouse technology bounced a focused beam of light off a highly-reflective mouse pad onto a

sensor. The mouse pad had a grid of dark lines. Each time the mouse was moved, the beam of light was interrupted

by the grid. Whenever the light was interrupted, the sensor sent a signal to the computer and the cursor moved a

corresponding amount. This kind of optical mouse was difficult to use, requiring that you hold it at precisely the right

angle to ensure that the light beam and sensor aligned. Also, damage to or loss of the mouse pad rendered the mouse

useless until a replacement pad was purchased. Today's LED-based optical mice are far more user-friendly and

reliable.
