Method and system for registering domain names with use of national languages in non-english-speaking countries / 2249843
Method includes detection of connection of user computer to Web-site of sub-domain on national language and selects service of registration of domain name on national language, performing software extension for automated forming of combination of symbols of English alphabet, matching domain name, based on national language, determining, whether such combination of English symbols was registered before as existing domain name, and, if not, then it is registered as domain name.

Computer keyboard / 2266556
Keyboard has controller, data processing device and keys mounted on a panel with transparent key heads, in each of said heads light diode is positioned in form of rectangular frame, used for reproduction of two mutually contrasting colors, one at a time, and a fourteen-segment indicator positioned inside aforementioned diode with working side directed towards face surface of key head, used for reproduction of symbol with color, contrasting with any one of two colors produced by light diode.

Input devices and their use / 2267183
In a small keyboard the regions of independent and combined keys are located in alternating columns, the columns of the regions of combined keys include multiple digital columns and at least one column containing regions of keys corresponding to the symbols of punctuation.

Keyboard / 2268481
Keyboard has left and right portion, meant respectively for use on appropriate working side by means of left hand wrist and right hand wrist accordingly, while angle between working side of each portion of keyboard and horizontal plane is 60-150°, and keyboard itself is provided with supporting means for carrying hand wrists during working with keyboard, while bearing means are made to allow primarily horizontal displacement of wrists relatively to appropriate portion of keyboard. Keyboard is equipped with checking side, directed in opposite direction relatively to main side, while performing actions using a part of keyboard cab be visually checked on checking side.

Method for controlling serviceability of a keyboard / 2269815
Method includes forming a series of testing pulses of current with given amplitude and length, sent to each piezoelectric element of key, value of resulting voltage component variable in stabilized state is measured, result of measurement is compared to given maximal and minimal boundary values.

Method for operation of fast writing system and fast writing device / 2277719
In accordance to invention, a field with keys for all consonants appears, and also a key for vowels having different position and functions. Stylus movements, such as key selection or movement along one of eight linear directions, and also combinations of these stylus movements make it possible to realize all elements of writing process.

Portable unit for making data input into digital device / 2284566
Device has control panel comprising table with a group of symbols in several fields and main board having pressure contacts and two selection members movable in parallel to rows and columns of the table until they find their places near in front of or above a pressure contact in the extension of selected row/column, pressure mechanism for varying pressure contact positions by means of selection members located in front of or below the latter, and several additional manually driven pressure contacts, their number being equal to field symbol maximum.

Method for visual information representation (variants) / 2288499
The image on the display of an electronic device is divided into sections. Each section is associated with a certain key on the digital keyboard. Every section of the display represents visual information and visual indication of the chosen key on the digital keyboard. Every section is associated with a service and by choosing a key information associated with a service for this key is represented on the display.

Ergonomic keyboard arrangement / 2293367
Keyboard is divided to two sections disposed correspondingly to anatomical peculiarities of arm's wrist. Keys are grouped according to purpose and character of application. Mutual disposition of keyboard modules in section corresponds to position of any finger of operator, which position the fingers take at natural relaxed state relatively each other. Keyboard modules in first group are disposed in parallel or radial at small angle to each other within limits of value of possible adjacent angles among elongated fingers. Keyboard modules of second group are disposed within range of movement of thumb. Several functions of keyboard are brought in coincidence.

Computer keyboard / 2309449
Keyboard includes functional key "Enter" mounted in the body, positioned in lower right corner of keyboard, and a set of universal programmable optically active keys. Programmable keys are positioned in three rows, where five keys of upper row, seven keys of middle row and five keys of lower row correspond to Russian-English version. Functional symbol table selection key, positioned in left upper corner of keyboard, consists of two electrically independent, but mechanically connected parts, where doubled key has shape of "U" letter with stretched width, and is oriented across other key rows and provided with two transition pointers in form of arrows or triangles directed oppositely.

Device to indicate digital symbols with power-saving mode / 2427930
Device to indicate digital symbols has a power-saving mode of operation. When changing into a power-saving mode, permission voltage is supplied with a level of logical "1" is sent to additional inputs of logical elements AND-NOT of a combined controlled converter of a binary-decimal code into a seven-position and four-position codes, on the basis of which the four-position code signal is formed. At the same time outputs of these logical elements AND-NOT connect to upper (A, B, G, F) elements of seven-segment format of an indicator. Prohibiting voltage with a level of logical "0" is sent to additional inputs of logical elements AND-NOT, where a signal of seven-position code is formed. At the same time outputs of these logical elements disconnect from control of indicator seven-segment format elements. When forming four segment decimal symbols with a reduced format, the average equivalent area of segments differentiation by sign increases without changes in signs brightness.

Transfer of characters in subpixel resolution / 2439676
Method to transfer text with subpixel accuracy in a computing environment, comprising a terminal server and a terminal client, including transfer of an image of a single bit card of a character line from a terminal server into a terminal client, includes stages, at which in a terminal server, prior to sending the image of the single bit card to a terminal client, text descriptions are generated, which include information that describes borders of a character for a word character line or phrases, which are repeated, by colours, in order to be able to describe borders of a character with subpixel accuracy; a single bit card of character line is developed in a terminal server prior to sending an image of a single bit card into a terminal client, besides, the bit card image includes one or more bit card pixels, which form one or more edges of a bit card; and the image of the single bit card is sent into a terminal client, including sending colour images and alpha-factor values for one or more pixels of the bit card, besides, colour values and alpha-factor values are used to mix a background in a terminal client by using colour values by a terminal client and values of alpha-factor together with information on a background in a terminal client.
