A watch has never been just a tool for measuring time. It was always a symbol which allowed an owner to express its individuality and social position.
There are watches with a thermometer, barometer, GPS receiver, that is why a watch with a camera is no wonder. But still, when comparing a watch with a thermometer and this one with a camera I arrived at the idea that these categories are completely different. A thermometer in my watch doesn't yield to a good electronic thermometer with a digital display - the accuracy is 0.1 degree, while the camera is a decorative element.
The model from Casio we have tested can make black-and-white shots, write comments, record about 100 shots into the 1 MBytes camera's memory and transfer them via an IR port into a computer. There is already a model with a color camera, but it is still a watch and not a photo camera.

The lens with a 1.1 mm focal length and a fixed aperture equal to F:2.8 shots objects located at the distance from 30 cm to infinity with a 1/14 CMOS sensor. An electronic shutter works with the exposure from 1/11 to 1/1660 sec depending on illumination. The illumination range you can make photos at varies from 100 to 45000 luxes. Since an image is registered and recorded line by line, it's important at what frequency the surrounding light flickers. In order to avoid banding connected with flickering of glow-discharge lamps there are such settings as "daylight", "50 Hz line frequency" and "60 Hz line frequency".
The display of the watch measuring 20 by 20 mm is used as a viewfinder and for the following watching of photos. It displays a complete image: 120 X 120 pixels at 16 grey gradations. You can make comments for each photo consisting of 24 symbols at most.
The watch ships together with an IR receiver which is to be connected to a serial port. The WQV Link program is used to transfer photos into a computer and order them in an album.
Although the WQV Link allows us to choose a computer receiver instead of the one supplied with the watch, I failed to connect the computer with an IR port of the notebook.
Time is displayed on a graphics screen. Although figures are quite big, I accustomed to a usual digital display since it's more convenient and contrast. Unfortunately, the camera works in the energy-saving mode, and you have to press a button to find out the time. The description says the battery CR2032 suffices for 6 months if the camera is used during 60 sec every day. The procedure of opening the case is very simple: you don't need any special-purpose screwdrivers and can open it with any coin.
The watch also contains a timer, a stop-watch, a calendar. Besides, it can be implemented in cases with different water-proof degrees (including cases meant for diving with an aqualung). But I think light under water is not enough to make photos.
In general, today such watch measuring 40X52X16 mm and weighting 32 g is a good competitor against a golden cuckoo-clock.

future computers

Today's computers operate using transistors, wires and electricity. Future computers might use atoms, fibers and light. Personally, I don't give a byte what makes it tick, as long as it does the job. If I could accidentally spill my coffee and not have it cost $848, that would be a cool feature.
But let us assume that you are not still bitter from a recent laptop replacement. You might stop to consider what the world might be like, if computers the size of molecules become a reality. These are the types of computers that could be everywhere, but never seen. Nano sized bio-computers that could target specific areas inside your body. Giant networks of computers, in your clothing, your house, your car. Entrenched in almost every aspect of our lives and yet you may never give them a single thought.
Understanding the theories behind these future computer technologies is not for the meek. My research into quantum computers was made all the more difficult after I learned that in light of her constant interference, it is theoretically possible my mother-in-law could be in two places at once.
If you have the heart, take a gander at the most promising new computer technologies. If not, dare to imagine the ways that billions of tiny, powerful computers will change our society.

humanoid robot

A humanoid robot is an autonomous robot because it can adapt to changes in its environment or itself and continue to reach its goal. This is the main difference between humanoid and other kinds of robots. In this context, some of the capacities of a humanoid robot may include, among others:

self-maintenance (like recharging itself)
autonomous learning (learn or gain new capabilities without outside assistance, adjust strategies based on the surroundings and adapt to new situations)
avoiding harmful situations to people, property, and itself
safe interacting with human beings and the environment

Like other mechanical robots, humanoid refer to the following basic components too: Sensing, Actuating and Planning and Control. Since they try to simulate the human structure and behavior and they are autonomous systems, most of the times humanoid robots are more complex than other kinds of robots.
This complexity affects all robotic scales (mechanical, spatial, time, power density, system and computational complexity), but it is more noticeable on power density and system complexity scales. In the first place, most current humanoids aren’t strong enough even to jump and this happens because the power/weight ratio is not as good as in the human body. The dynamically balancing Dexter can jump, but poorly so far. On the other hand, there are very good algorithms for the several areas of humanoid construction, but it is very difficult to merge all of them into one efficient system (the system complexity is very high). Nowadays, these are the main difficulties that humanoid robots development has to deal with.
Humanoid robots are created to imitate some of the same physical and mental tasks that humans undergo daily. Scientists and specialists from many different fields including engineering, cognitive science, and linguistics combine their efforts to create a robot as human-like as possible. Their creators' goal for the robot is that one day it will be able to both understand human intelligence, reason and act like humans. If humanoids are able to do so, they could eventually work in cohesion with humans to create a more productive and higher quality future. Another important benefit of developing androids is to understand the human body's biological and mental processes, from the seemingly simple act of walking to the concepts of consciousness and spirituality.
There are currently two ways to model a humanoid robot. The first one models the robot like a set of rigid links, which are connected with joints. This kind of structure is similar to the one that can be found in industrial robots. Although this approach is used for most of the humanoid robots, a new one is emerging in some research works that use the knowledge acquired on biomechanics. In this one, the humanoid robot's bottom line is a resemblance of the human skeleton.

futer cars

The automobile in the future will change dramatically. It has reached its peak and will soon run out of steam. It will be superceeded with better transportation technologies, just like canals by railroads and railroads in turn by cars.
In the coming decade there will be many improvements in a car - engine, fuel, materials, but especially smart internals. Sensors and computers will make it possible to co-ordinate car movement and have computers drive cars. People who want to take a Sunday drive can get a Sunday ride.
Large scale co-ordinated networks of vehicles will emerge, similar to projects like ULTra. Cars may move from roads to guideways or string rails. Flying cars will be introduced. Innovative replacements such as Segway will become popular.

asimo brewbot

asimo brewbot

Since then, the Tassimo Brewbot has established a name for itself as an effective one-cup hot beverage system that can make up to seven varieties of beverages with one machine. Like all of those found in the Tassimo line, the Tassimo Brewbot makes use of T-discs or Tassimo Discs which are small, pre-packed capsules just a little bigger than marmalade jam packs. Quite an apt size as the T-Discs are partnered with the Tassimo Brewbot machine that can just as easily fit one part of your kitchen counter. Inside the capsule are ingredients for a variety of hot beverages. The Tassimo Brewbot has the ability to make seven drinks, regular coffee, tea, espresso, hot chocolate, as well as milk-based drinks like lattes, cappuccinos and cremas. Each Tassimo Brewbot T-Disc contains a barcode which the machine reads out of to give it instructions on how to prepare the drink from factors such as water temperature, amount of water and its brewing time. The rest is taken care of by Tassimo Brewbot. All you have to do is just press the button and wait for the Tassimo Brewbot to fill your cup.
Kraft works with twelve different brands to provide a variety of over 40 different drinks for its Tassimo Brewbot customers. Thank youu...

Toay special 3G mobiles

The first generation (1G) began in the early 80's with commercial deployment of Advanced Mobile Phone Service (AMPS) cellular networks. Early AMPS networks used Frequency Division Multiplexing Access (FDMA) to carry analog voice over channels in the 800 MHz frequency band.
The second generation (2G) emerged in the 90's when mobile operators deployed two competing digital voice standards. In North America, some operators adopted IS-95, which used Code Division Multiple Access (CDMA) to multiplex up to 64 calls per channel in the 800 MHz band. Across the world, many operators adopted the Global System for Mobile communication (GSM) standard, which used Time Division Multiple Access (TDMA) to multiplex up to 8 calls per channel in the 900 and 1800 MHz bands.

The International Telecommunications Union (ITU) defined the third generation (3G) of mobile telephony standards IMT-2000 to facilitate growth, increase bandwidth, and support more diverse applications. For example, GSM could deliver not only voice, but also circuit-switched data at speeds up to 14.4 Kbps. But to support mobile multimedia applications, 3G had to deliver packet-switched data with better spectral efficiency, at far greater speeds.

However, to get from 2G to 3G, mobile operators had make "evolutionary" upgrades to existing networks while simultaneously planning their "revolutionary" new mobile broadband networks. This lead to the establishment of two distinct 3G families: 3GPP and 3GPP2.

The 3rd Generation Partnership Project (3GPP) was formed in 1998 to foster deployment of 3G networks that descended from GSM. 3GPP technologies evolved as follows.
