298 results about "Control character" patented technology

In computing and telecommunication, a control character or non-printing character (NPC) is a code point (a number) in a character set, that does not represent a written symbol. They are used as in-band signaling to cause effects other than the addition of a symbol to the text. All other characters are mainly printing, printable, or graphic characters, except perhaps for the "space" character (see ASCII printable characters).

Semantic user interface

A system and method that allows a user to use their everyday language or user defined words to operate a computer in a highly efficient way. In short, every word, letter, control character and symbol is potentially actionable. A computer user's productivity is dramatically increased by making available those functions that enable a user to produce most of his work through simple, language-based commands. The present invention provides an intuitive interface, referred to as a semantic user interface (SUI), that enhances the operation of the current standard window-based interface in a manner that is simple, richer and natural. By leveraging all of the richness and power inherent in a user's language, the present invention provides an important tool that allows the personal computer to operate in a manner that is much closer to our natural way of interacting. A user is allowed to enter "commands" in his everyday natural language in order to control the operations of the computer. All commands are language-based and user-defined. These commands can be entered from any context of the user's computer (e.g., any application or operating system workspace). The commands allows a user to launch applications and navigate within applications by using language rather than clicks from a pointing device such as a mouse. It also allows the replacement of keystrokes with stored words or keystrokes. The system also keeps a complete archive record of all the text content the user provides as input, regardless of which application program or operating system window the user is operating in at the time. The combined set of all user defined commands and the memory of all the input text that is stored in the archive constitutes the personality profile and is transportable from one computer to another.

Methods and systems for TMDS encryption

The present invention is directed to systems and methods for protecting digital content during transmission. One version of the invention provides a method for encryption in a high-speed digital video transmission system that includes the steps of: a) performing transition controlled encoding of a first sequence of n bit data words into encoded n+1 bit data characters where the n is a positive integer, b) performing XOR masking of the encoded n+1 bit data characters with an XOR mask to produce masked n+1 bit data characters; c) DC balancing the masked n+1 bit data characters to produce DC balanced, masked n+2 bit data characters; d) scrambling the DC balanced, masked n+2 bit data characters using a scrambling formula to produce encrypted n+2 bit data characters; e) encoding control data into encoded n+2 bit control characters, f) generating a serial data stream in response to the encrypted data characters and encoded control characters, and g) transmitting the serial data stream over a communication link. Subsequent to step (e) and prior to step (f), the method can further include the step of encrypting the encoded n+2 bit control characters, such that the generating step generates a serial data stream in response to the encrypted data characters and the encrypted control characters.

Method and apparatus for a web based punch clock/time clock

A system and method for building GUI screen screens for a time keeping and expense tracking system includes a time keeping and expense tracking (TKET) server that includes computer instructions that define logic for building GUI screen screens according to user definitions, communication channel throughput capacity, and terminal capacity. Initially, the TKET server examines a user's ID to determine his group affiliations and ability levels for modifying the parameters, objects, and layout of a GUI screen. Thereafter, the TKET server allows the user to make changes according to his defined abilities. For subsequent sessions, the TKET server builds a GUI screen according to the previously defined parameters. One embodiment of the present invention, the TKET server is operable to receive communication signals transmitted by way of a wireless communication channel and to generate corresponding display screens that are responsive to the user terminal type. If the user terminal is a mini laptop having wireless communication capability, for example the TKET server transmits GUI screen display signals in a WAP protocol for display thereon the user terminal. On the other hand, if the user terminal is merely a cellular phone, then the TKET server is operable to transmit a very limited set of display signals primarily comprising text and control characters. The TKET server is operable to act as a remote time clock. Accordingly, the TKET server is formed to receive and interpret signals that define the user ID, an account code, and whether a start or stop timekeeping event has been selected. The TKET server also is operable to prompt an IVR to interact with the user.
