摘要： Format control apparatus enables the printing or display of characters with selectively controllable spacing. Data which represents characters is stored in a buffer store (42) and applied to address a character generator (50) which provides the relevant dot row information of the characters under the control of a row counter (62). The output of the character generator (50) is supplied in parallel to a first shift register (64) which is controlled by a clock divider circuit (54). A serial output from the first shift register (64) is applied to a second shift register (66) coupled to a label (68) which supplies data in a group of parallel bits adapted to a utilization device for the formatted character information. The row counter (62) and clock divider circuit (54) are settable under the control of a mode control circuit (48) to enable the formatting of selectively spaced characters. The character generator (50) may store a plurality of selectable character fonts. A settable character counter (46) controls the number of characters in a line of characters.

摘要： In a control system (10) for a plasma display panel (12) having a cell (14a-14i) formed at the cross-over point of each of the panel's column and segment electrodes (C u, C u, C u and S u, S u, S u) AC drive signals having positive and negative components are simultaneously applied to the column and segment electrodes (C u, C u, C u and S u, S u, S u) associated with a designated cell (14a-14i) of the panel (12). These drive signals are 180` out-of-phase and are arranged to produce across the designated cell a voltage swing of sufficient magnitude to produce a discharge therein. In one embodiment of the drive scheme, the positive and negative components of each drive signal are equal. In a second embodiment of the drive scheme, the positive and negative components of each drive signal are not equal. The control system (10) includes a DC-to-AC convertor for producing the AC drive signals, a driver circuit (20a, 20b, 20c) associated with each column electrode (C u, C u, C u) of the display panel and a driver circuit (18a, 18b, 18c) associated with each segment electrode (S u, S u, S u) of the display panel. Each of the column and segment driver circuits is operable to provide to its associated column or segment electrodes both of the components of its associated AC drive signal if it is selected or only one of the components of its associated drive signal it is not selected. In this way, the positive and negative components of the AC drive signals are selectively applied to the panel's column and segment electrodes to produce a desired illumination pattern.

摘要： A teleprinter terminal (10) includes a keyboard (70), a thermal printer (62) and communications electronics (44, 56, 58), each of which is operated by means of a self-contained microprocessor (40, 52, 60) which can store and release data, in order to provide a simple and reliable control system for the terminal. The three microprocessors (40, 52, 60) are interconnected by four bit buses (PRINT DATA, TRANSMIT DATA/STATUS) for data transfer operations between the processors which are done in bytes but the four-bit buses forces the bytes to be transferred in two, four-bit exchanges. One four-bit bus (PRINT DATA) is used to connect the communications processor (52) and the keyboard processor (40) with the printer processor (60) for transfer of data to the printer and a second four-bit bus (TRANSMIT DATA/STATUS) is used to connect the keyboard processor and the communications processor for transfer of data to the communications electronics. The communications electronics includes a serial communications interface (44, 58) for data transmission and reception and a parallel interface (56) for data reception only.

摘要： A driving circuit for a gas-discharge display device (20) includes a pair of switching members (94, 144) and the secondary windings (92) of a transformer (118) wired in series with one of the switching members. The switching members in response to receiving out-of-phase control signals alternately apply a low voltage pulse to the display device. The secondary windings of the transformer output continuously a high voltage pulse in phase with one of the switching members. Upon the generation of appropriate control signals enabling the operation of the switching members, a voltage of sufficient magnitude is applied to selected cell segments in the display device to fire the cells. The transformer together with the low voltage pulses are driven by a high frequency clock to provide a high intensity display operation.

摘要： A self-correcting memory system (10) includes internal error detection and correction circuitry (20) that periodically accesses each data word and a group of ECC check bits associated with each data word stored in the memory system (10). The error detection and correction circuitry (20) includes an ECC checking circuit (36) that receives the accessed data word, generates ECC bits, and compares those ECC bits to the group of ECC check bits associated with the data word. The resulting signal is used to correct any single bit in error, and to indicate the presence of a double bit error. A self-correct address counter (44) is cascaded to a refresh address counter (42) in the control circuitry (41) of the memory system (10) so that the accessing of each data word occurs during a refresh cycle of the memory system (10).

摘要： A magnetic bubble domain memory device that includes a magnetic domain data chip having a major-minor (20, 26) loop organization with on-chip firmware providing redundancy information enabling the use of the chip even though one or more defective minor loops may be present thereon. One of the pages (68) is written in the minor loop (26), where a page is defined as a common bit position in each of the plurality of minor loops, with a series of magnetic domains having an odd total number. The next succeeding page (70) in the minor loops contains a series of magnetic domains and voids which are representative of the loop numbers of defective minor loops on the chip with the remaining pages (72) in the minor loop having an even number of magnetic domains contained in each of the pages. Collectively, the pages containing the odd and even number of magnetic domains together with the page containing the map of the defective minor loops comprise the on-chip firmware providing redundancy information. This magnetic domain structure is capable of screening out defective minor loops in the read and write operation, and enables synchronization of the magnetic domain device such that a selected page of data may be readily accessed from a plurality of minor loops when desired.

摘要： A symbol decoding system incorporated in a plurality of NMOS/LSI chips (22, 24, 28, 30) generates data representing numerical characters encoded in the symbol. Scanning means (20) generates signals (RTV, STV) in response to the scanning of a plurality of bars and spaces, which signals are decoded by a first chip (24) as valid and invalid characters, the valid characters being recognized by a second chip (28) which stores the valid characters and enables a microprocessor chip (30) to receive the valid characters assembled as part of the symbol for processing thereof. Logic circuits enable test numerical characters to be generated in response to test signals outputted by the microprocessor chip (30).

摘要： A transition code sensing system includes a record member (32) on which is located a plurality of bar code symbols (34), each of which comprises a data channel (20) and a clocking channel (22). The record member is inserted into a data terminal device and intermittently driven through a printing station in which a sensing member (36) senses the data channel out of phase with the sensing of the clocking channel and generates signals in response thereto. A circuit coupled to the sensing member will process the generated signals and transmit the processed signals to a utilization device. Upon processing the signals representing the last bar code symbol (29) on the record member, the circuit will generate a control signal (88) for stopping the movement of the record member through the printing station, thereby conditioning the record member for a subsequent printing operation.
