Abstract: We claim a hammer driven actuator that uses the fast-motion, low-force characteristics of an electro-magnetic or similar prime mover to develop kinetic energy that can be transformed via a friction interface to produce a higher-force, lower-speed linear or rotary actuator by using a hammering process to produce a series of individual steps. Such a system can be implemented using a voice-coil, electro-mechanical solenoid or similar prime mover. Where a typical actuator provides limited range of motion or low force, the range of motion of a linear or rotary impact driven motor can be configured to provide large displacements which are not limited by the characteristic dimensions of the prime mover.

Abstract: A generic address resolution system facilitates communications among multiple network applications with heterogeneous addressing mechanisms, thereby allowing the network applications to interoperate with each other and/or with modules for providing enhanced functionalities. The address resolution system includes a resource mapping module that modularizes the components needed for address resolution and abstracts content from the underlying address types and content used by the network applications. The address resolution system includes a context engine that analyzes the addressing data to be resolved, selects one or more appropriate destination network applications based on contextual rules, and creates the application mapping template for the end-end routing of the communications among the network applications.

Abstract: A facsimile apparatus connected on an ISDN side in a communication network in which the ISDN is connected to a telephone network includes network identifying means for identifying whether an incoming data sending party is an ISDN terminal or a telephone network terminal, CNG signal detecting means for detecting a CNG signal received via a B channel, and changeover means for changing over between automatic reception and manual reception. In a case where the CNG signal is detected, a response is made in a facsimile mode. In a case where the CNG signal is not detected, a response is made in a facsimile mode if automatic reception prevails and in a telephone mode if manual reception prevails. This arrangement eliminates communication failure due to a difference in mode between a calling side and a called side regardless of the network terminal from which a call is received.

Abstract: An intelligent interface to enable a personal computer or the like to be used as a telex transceiver.

Abstract: A method for controlling the sending of a response from a telematic reception terminal (teletex, G4 facsimile, and mixed mode) is provided. The receiver includes a PAMB counter whose count indicates the remaining number of page attribute management function blocks (PAMBs), each including predetermined various attribute data relating to each page, such as line density, coding mode, page size, page number and document number. When one of predetermined commands, such as a page boundary command or a document end command, has been received, the receiver checks to see whether or not the count of the PAMB counter is equal to or larger than a predetermined value. And if it has been found to be equal to or larger than the predetermined value, a response is sent to the transmitter. Thus, the transmitter is permitted to send the information of the following page.

Abstract: In a telematic system, a plurality of response timings for a page boundary command, a page end command and the like from a sending system are prepared. A proper timing is selected in accordance with the type of sending system or an instruction from the sending system.

Abstract: In public videotex (Btx) terminals, different pages are displayed successively on the screen in the off-line mode (e.g., advertisements and user instructions). To be able to update such off-line pages at low cost, a page memory in the terminal is constructed as a random-access memory (46). A central operating facility contains an editing device in which the information and control characters required to display an off-line page are produced. These characters are transmitted to the terminal and written into the random-access memory (46). This may be effected automatically when the supply voltage is turned on.

Abstract: A teleprinter has a printer for printing received or manually entered characters in a row-by-row fashion. The characters of a row are initially stored, and only following the occurrence of a predetermined control signal, for example a "carriage return" signal, are all of the characters of the pending row printed. The teleprinter has a display unit for displaying at least a portion of those characters of a row which have not yet been printed. The display unit may also display at least one preceding and at least one following row in addition to the row being printed.

Abstract: The disclosure concerns a communication system for line printers, such as teleprinter equipment, via high-quality radio communications. The repetition of the signals received mutilated takes place per line of signals at the end of a number of lines. The transmitter for the system comprises a counter from which the line number is fed to the transmitter during the line printer return or the line feed period up to the end of the page or the message. The receiver detects which lines have been received mutilated and registers their line numbers. Then the request for repetition of the numbered mutilated lines is made at the end of each message and at the end of each page of the message, if the message is longer than a page, for example, 32 lines.
