Inside an optical computer mouse
An optical mouse is much more hi-tech than a ball mouse. Where a ball mouse has quite a few moving parts, an optical mouse is almost entirely electronic (it has almost no moving parts).
Here's the inside of a typical optical mouse and a few of the main components. The most interesting bits are in the center (where the LED light shines down onto your desk) and at the front (where button presses are detected by switches):
1) An LED at the back generates red light and shines it horizontally, from the back of the mouse toward the front (from the left to the right of this photo).
2) A plastic prism bends (refracts) the light from the LED at an angle, down onto the desk.
3) A light-detector chip measures light reflected back up from the desk, converting the analog movements of your hand into digital signals that can be sent to your computer.
4) The scroll wheel at the front of the mouse is mounted on a switch mechanism that detects both how much it's rotated and whether you've pressed it (it functions like the central button of a conventional mouse). Rotations of the scroll wheel can be detected in a variety of different ways. Some mice use potentiometers (broadly, variable resistors), similar to the volume control on a radio but able to turn around multiple times. Others use various kinds of rotary switches or optical (rotary) encoders to convert analog wheel movements to digital signals.
5) A microswitch detects when you press the right mouse button. There's an identical switch on the other side to detect the left mouse button.
6) The USB cable connection carries digital information from the mouse to your computer.

World's First Flexible 8-Bit Asynchronous Microprocessor
Seiko Epson has announced that it has developed the world's first flexible 8-bit asynchronous microprocessor using low-temperature polysilicon thin-film transistors (LTPS-TFTs) on a plastic substrate. With energy consumption reduced by 70% compared to the synchronous microprocessors now in everyday use, Epson is now researching potential applications for its invention. The results of Epson's research were announced at ISSCC2005, the International Solid-State Circuit Conference, held earlier this month in San Francisco in the United States

The Euclid Space Telescope reveals new insights into dark matter and dark energy
Euclid – named after the ancient Greek mathematician – is part of the European Space Agency (ESA) Cosmic Vision programme, with NASA providing some assistance in the form of instrumentation and scientific analysis. Launched in 2020 and placed at Sun-Earth Lagrange point L2, its mission duration is six years, during which time it studies the nature of dark matter and dark energy.*

The 5G standard is released
By 2020, the next major cellular wireless standard has been adopted.* This continues the trend seen since 1981 - in which a new mobile generation has appeared roughly every 10th year. The 5G family of standards is a major leap from previous generations in terms of power and functionality. Among its key features are:
Pervasive networks providing ubiquitous computing. The user can simultaneously be connected to several wireless access technologies and seamlessly move between them. These can be 2.5G, 3G, 4G or 5G networks, Wi-Fi, WPAN or any other contemporary access technology. Multiple, concurrent data transfer paths can be easily handled.
Group cooperative relay. High bit rates are now available in a larger portion of the cell, especially to users in an exposed location in between several base stations. This is achieved by cellular repeaters, together with macro-diversity techniques (also known as group cooperative relay), as well as beam-division multiple access.
IPv6, where a visiting care-of mobile IP address is assigned according to location and connected network.
High-altitude stratospheric platform station (HAPS) systems, delivering high-speed Internet service to very large geographical areas.
Wearable devices with AI capabilities, offering greater levels of user interaction and personalisation.
One unified global standard with full compatibility, no matter what brand or model.

Texting by thinking
In addition to 5G, phones are becoming available with the option of texting by thought power alone.* This is achieved by a sensor-mounted headset worn by the user. The device contains brain-machine interface technology which analyses brain waves, converts them into digital signals and displays the resulting letters on-screen.*
Some of the higher end models feature glasses or visors, with displays built into the lenses. This allows completely hands-free texting, effectively creating a form of virtual telepathy. The process is rather slow at this stage - requiring a high degree of mental concentration. It is more of a novelty for now. However, advances in coming years will enable smooth and fast interactions, revolutionising the world of communication.

Video games with truly lifelike CGI
Thanks to exponential growth in computing power, video game characters now achieve a truly lifelike appearance when played with the latest graphics cards. Advances in 3D modelling techniques have allowed programmers to recreate the subtlest of facial features, expressions, movements, lighting and other physical effects. Complex interactive scenes featuring entirely computer-rendered people are becoming indistinguishable from reality.* This is raising a number of ethical issues - due to the sheer level of realism now available, combined with ongoing advances in AI technology. Meanwhile, Google Earth has become so advanced that users can browse and move around in a smooth, photographic-quality 3D environment with moving cars and day/night cycles.*

civil: skin,body
architect: costume,coolers,etc
ice: heart etc
computer: memories etc
but the fact is the main thing is
BRAIN....will be....E.C.E
if brain dead no other parts lives ,no use for that person ....
