A reduced size and split keyboard arrangement is provided for a portable computing apparatus. The arrangement of the keys, together with mapping of multiple characters to the keys allows reduction of the keyboard to a smaller footprint of a handheld device. Keys may have a single character or multiple characters mapped thereto. For the keys with multiple character mapping, the selection of the character may be by done by simultaneous or near-simultaneous pressing of adjacent physical keys. In one embodiment, disambiguation software may be employed to determine selection of a character from a physical or virtual key with multiple characters assigned thereto.

Multiple sets of character data having termination characters are compared using parallel processing and without causing unwarranted exceptions. Each set of character data to be compared is loaded within one or more vector registers. In particular, in one embodiment, for each set of character data to be compared, an instruction is used that loads data in a vector register to a specified boundary, and provides a way to determine the number of characters loaded. Further, an instruction is used to find the index of the first delimiter character, i.e., the first zero or null character, or the index of unequal characters. Using these instructions, a location of the end of one of the sets of data or a location of an unequal character is efficiently provided.

The length of character data having a termination character is determined. The character data for which the length is to be determined is loaded, in parallel, within one or more vector registers. An instruction is used that loads data in a vector register to a specified boundary, and provides a way to determine the number of characters loaded, using, for instance, another instruction. Further, an instruction is used to find the index of the first termination character, e.g., the first zero or null character. This instruction searches the data in parallel for the termination character. By using these instructions, the length of the character data is determined using only one branch instruction.

A character recognition method for recognizing characters on an article having multiple character-bearing areas, such as a license plate, first involves obtaining image data from an image of the article. The method then assigns at least one parameter to a selected character-bearing area on the article. The method then attempts to obtain a correct frame which expresses the correct positional relationship between the selected character-bearing area on the article with other character-bearing areas of the article, and then uses that correct frame to perform character recognition with respect to each of the character-bearing areas of the article. To obtain the correct frame, the invention compares the image data of the article with plural candidate frames. The plural candidate frames are calculated using the predetermined positional correlation between (1) the selected character-bearing area [as represented by the at least one parameter] and (2) other character-bearing areas of the article.

The player will be rewarded with the corresponding prize(s) based upon the outcome of the combination inner video display and rotatable object.

Texts including required message are entered with a small number of keys such as those of a cellular telephone. In this case, a conversion table is unnecessary and the number of key operations is reduced. The number of input characters or input character strings composed by sequentially selecting one from a plurality of alphabets distributed to sequentially entered keys is relevant to the number of operation keys (N) raised to the number of distributed character (M) power (-NM) including meaningless characters or character strings and, with respect to these, character conversion is executed by referring to a dictionary means, through the operation of the conversion / next candidate key. The dictionary means stores numeric strings and words of meaningful characters or character strings among the said characters and character strings.

A method and apparatus to decrease the amount of time it takes to obtain friendly names of Bluetooth devices is presented. A name server caches friendly names for devices that it has acquired from other devices or from other name servers. The name server is any device that caches friendly names of Bluetooth devices and that makes the friendly names available to other devices. A requesting device determines if a name server has responded to an inquiry command. If a name server has responded, the device gets the friendly names the name server has cached and requests the friendly names of devices that responded that have not been cached by the name server. Identification of a name server is accomplished by embedding a marker in the friendly name field after the null character to indicate that the device is a name server.

Passing input strings through an application programming interface between functions that take null byte terminated strings as arguments, where at least some of said input strings contain null bytes internally. This is accomplished by storing the positions of the null bytes relative to the start of the block and storing the non-null bytes in their relative order to prevent said internal null strings from being treated as terminal null strings

The invention discloses a type setting method and system for laws and regulations. The method includes the steps: firstly, processing tags in an area needing type setting through regular expressions and switching the tags into HTML (hypertext markup language) linefeed tags P; secondly, automatically selecting all contents in the area needing type setting through a selection function; finally, sequentially processing text formats, volume titles, chapter titles, section titles and item formats in the area needing type setting according to preset standards to set types of the area needing type setting. By sequentially processing the text formats, the volume titles, the chapter titles, the section titles and the item formats in the area needing type setting, features of the laws and regulations can be more accurately expressed through type setting effects. The tags are processed through the regular expressions, so that the text formats and paragraph formats are reserved, and any other tags, types and meaningless null characters are removed. Besides, the contents in the area needing type setting are automatically selected, and one-key type setting is truly realized.
