Three very compact models of concentrators USB appeared in the assortment of the Japanese company elecom. The special features of new product, besides compactness, are the bright colors, selected for the deceptive get-up, and support USB 2.0. The first  USB- concentrators (U2H- CR 2b) has two ports and weigh 36 grams. This model can be black or orange color. The second product (U2H- CR 3b) has three ports. It weighs 44 grams and it is accessible in three colors: black, white and yellow. The third model (U2H- CR 4b) with a weight of 46 grams is equipped with four ports. Four-port concentrator is released in black case, white and dark-blue colors. As is evident in the photographs, the first concentrator and on the form resembles letter T, and two others are similar to the letter X. The selection of form is nonaccidental – because of the fact that the adjacent joints are located the right angle to each other, the commutation of cables and devices simplifies. At the same time, the arrangement of all joints in one plane made it possible to decrease the thickness of concentrators, which is 13 mm. bright colors they revive situation by the working table they descend probability that user it will forget concentrator, gathering its notebook for the journey. In each model there is the built-in cable with a length of 20 cm with the port for the connection to the computer. The load-carrying capacity of one port of the concentrator – 100 mA. The price of devices depends on a quantity of ports and lies within the limits of 15-20 dollars. elecom USB concentrators	Add Comment ( 0 ) ELECOM USB CONCENTRATORS

Many of us know about the fact that already sufficiently for a long time are conducted the developments in the region of quantum calculations. Let us recall that the quantum computers, in contrast to classical COMPUTERS, operate not with bits, but by kubit, in which is stored not discrete state 0 or 1, but their superposition. As a example it is possible to give the famous cat Schroedinger, that, being used in the closed box, which contains radioactive core and capacity with the poison gas, is both living and corpse simultaneously. On the commercial realization of quantum computer, until now there was no speech; however, the recently Canadian company D -Wave systems astonished peace by news about the fact that it is assembled to release the first in the world similar device already in the following year. This quantum computer, which received the name orion, will not be the narrowly specialized calculator, oriented, for example, it is exclusive in cryptography. Orion is device, capable after several cycles to solve the problems, to which in traditional COMPUTERS depart thousands of cycles. We deal here with the indeterminate polynomial tasks (Nondeterministic polynomial problems), which on the usual COMPUTERS are solved sufficiently heavily, also, moreover with the low accuracy, since in this case the methods of approximations are used. However, quantum computers are capable of simultaneously processing all possible solutions of problem and finding optimum in relatively small time. This property KK will prove useful in different the fields - from the search in BD to genetic engineering and the creation of new medicines. D -Wave systems promises already on the following week, on 13 February, to show the working prototype of its 16- kubit computer. The cooled to the boiling point liquid helium, processor orion is made from niobium (metal- superconductor) with the use of traditional lithograph. On its micro-architecture orion is similar to the programmed logical matrices (FPGA) and it can be by program reconstructed for the solution of different problems. quantum computer orion	Add Comment ( 0 ) QUANTUM COMPUTER ORION

The diagrams for the displays, which excute parallel-series and series-parallel conversion, are very extended in contemporary electronic devices. They  required part of cell phones, players MP3 and other devices, equipped with liquid-crystal screens. In reduction in the energy consumption of these converters one of the reserves for a increase in the time of off-line operation lies. The company fairchild semiconductor announced the production of converters from the second generation series uSerDes-uLP. Key special feature of the new product â€“ small energy consumption. According to the data of producer, the microcircuit, which received designation FIN324C, consumes to 65% less energy than its predecessors. Furthermore, new product does not need the external master oscillator and the support of configuration with two screens. The microcircuit of parallel-series and series-parallel converter FIN324C is produced in compact case of type BGA and MLP. The small sizes of case and the fitness for work over a wide range of  supply voltages (1,6-3,0 c) make the new product  being suitable for the wide circle of constructions. The price of microcircuit depends on the type of case and is 1,74 dollars for the version FIN324CGFX (BGA) and 1,66 dollars for the version FIN324CMLX (MLP). The deliveries of instruments already began. FIN324CGFX	Add Comment ( 0 ) FIN324CGFX

According by this  report, published by analytical company IDC, in the past year world-wide volume of deliveries CPC composed 5,5 mln. units, which to 28,5% is less than in 2005. The collapse of the market for palmtops was especially noticeable in the fourth calendar quarter. In three months it was possible to sell altogether only 1,5 million devices, which to 35,9% is less than during the same period year ago. Basic reason analysts see in strengthening the positions of smartphone. The products convergence, which unite the functions of organisation, universal player, gaming console and mobile connection, and also telephones, which present upper price sector, compose serious competition to computers. Their contribution introduced wireless computer networks and notebook. The general introduction Of wiFi, which allows for mobile users with notebook constantly to be located on connection, decreased the need for the autonomous miniature devices. The third noticeable factor specialists call a increase in the popularity of  navigators GPS, designed in the form self-contained instruments. They reduced demand for CPC, equipped with the  GPS of in the form additional modules and expansion card. IDC expects that the tendency of the passage of branch from CPC to the side of smarthpone will be preserved also in the present year. Concerning the most influential participants in the market, place in the first five they were distributed as follows: The first place continues to occupy the ancestor of the branch – company palm, which represented, true, in the year not of one new model. On the second it is located BY HP. It is remarkable, that with the curtailment of deliveries in the absolute expression, the market share HP increased by 5%. However, this doubtful reaching, since it can be evidence of the fact that the company simply does not manage to react to changes in the market. Position number three occupies Mio. This is only company among the important producers of palmtops, which showed a increase in the volume of deliveries both during the year and during the fourth quarter. By the fourth finished the company dell, which only insignificantly remained Mio according to the results of block, but which outdistanced it according to the results of year. Locks five the company acer. However, if, let us say, the leadership Of palm does not cause the doubts –  company belongs to 36,3% of market (year ago this value it was equal to 36,1%) for – that in the fifth place, besides Acer, pretend other producers, in particular, ETEN and Sharp (annual indices Of sharp higher than Acer). Market share, belonging Acer, were reduced in the year to the enormous value of 58,1%. CPC vs smartphone	Add Comment ( 0 ) CPC VS SMARTPHONE
