Patent EP-0178146-A2 (EP)
Inventor: LAWTON RODNEY JAMES
IPC: H03J7/02
Filed: 1985-10-07
Abstract: A radio receiver adapted to provide AM or FM demodulation functions comprising a discriminator and a log detector fed in parallel at intermediate frequency from a mixer, an output power amplifier stage fed selectively via a switch from the discriminator or alternatively from the log detector thereby to provide the function required, and a feed back control line via which the discriminator is coupled to a local oscillator which feeds the mixer whereby the frequency of the local oscillator is controlled. 
     The radio preferably also includes an exponential amplifier via which the switch is arranged to feed the log detector to afford the AM demodulation function. 
     The radio has the advantage of affording both AM and FM demodulation functions at low cost in a form which is simple and lends itself to integration techniques.

Abstract: A circuit arrangement (1) for checking remote data transmission, which is fitted between a data transmitting and/or receiving unit, for example a computer (4) or a terminal (7) and a modem (5) that can be connected to a data transmission line (6) or which is combined with the modem (5); the arrangement has a data buffer, a program memory, a microprocessor and a timer; a standard serial interface (V24) is used for connection of the unit transmitting and/or receiving the data and, when a separate modem (5) is used, a standard serial interface (V24) is also used for connecting said modem and an asynchronous transceiver is provided for connection of the standard serial interface(s) to the data bus of the microprocessor. The microprocessor controls a character-orientated or block-orientated transmission, depending on the arrival of data, in each case preceded by an alignment bit, the addressing in the transmitter-side and receiver-side data buffers taking place synchronously and to indicate how much of a received message was recognised, an ACK/NACK character is transmitted. After a number K of characters to be transmitted, the microprocessor sends a block check character BCC and, if characters to be transmitted are contained in the buffer memory, it effects transmission up to K characters and, if no correct message was last received and the previous character was a block check character, terminates the transmission. <IMAGE>

Abstract: A memory test pattern generator is disclosed, which generates a memory test pattern by reading out data from a microinstruction program memory - (1) according to an instruction of an address counter (2) and causing an address generator (4), a data generator (5) and a timing generator (16) to generate an address, a data and a timing signal, respectively, according to the read-out data. To test a memory device, which has internal address generation means and is capable of address accessing by supplying a clock, data representing the number of times of internal address generation is set in a repeat register (22). When a signal representing the internal address mode is read out from the microinstruction program memory (1), the increment of the address counter is stopped by a repeat controller (21 and the operation in the address and data generators is inhibited. At the same time, a timing set controller (26) and an internal address generator (23) are rendered operative, whereby an internal address is generated. An address multiplexer (24) replaces predetermined bits of a fixed address generated from the address generator with the internal address. Further, according to the internal address fixed data of the data generator is selectively passed bit by bit through a data multiplexer (25). Further, the timing set controller (26) produces timing data representing times before, during and after the internal address generation according to a timing reference signal from the repeat controller (21).

Abstract: Embodiments of apparatus are described for transmitting a stream of information bits by sending corresponding signals over a channel in a plurality of signalling slots. 
     A family of multi-dimensional convolutionally coded modulation systems achieves enlarged minimum distance between possible sequences of signal points, reduced number of error events with the minimum distance, acceptable peak-to-average power ratio, reduced number of signal points in each constituent two-dimensional constellation, immunity to rapid carrier phase changes, and reduced complexity, resulting in a reduced error probability when maximum likelihood decoding is used. 
     These advantages are achieved by the construction and by the partitioning into subsets of the multi- dimensional constellation, by the design of convolutional codes using those multi-dimensional subsets, by using a bit converter and a block encoder to convert a multi-dimensional constellation mapping into multiple two-dimensional constellation mappings, and by a simplified decoding technique.

Abstract: An operational amplifier circuit operable with a common-­mode input voltage variable over a substantially full range between given source voltages, wherein complementary first and second differential transistor pairs each consisting of transistors having current input terminals connected together are arranged with current mirror circuits and constant-current source devices so that the first differential transistor pair is turned off and the second differential transistor pair operates as input devices for a load circuit when the common-­mode input voltage approximates the lower sopurce voltage. An increase in the common-mode input voltage causes the first differential transistor pair to turn on and gives rise to a decrease in the current flowing through the second differen­tial transistor pair, in which instance the first differential transistor pair compensates for the reduction in the current through the second differential transistor pair by the action of the current mirror circuit associated with the two transis­tor pairs. The voltage applied to the load device is main­tained constant without respect to the common-mode input voltage supplied to the differential transistor pairs so that there are no noises generated during transition of the common-­mode input voltage through a certail voltage level.

Abstract: A magnetic tape cassette has an improved reel spring (16), slack limiter and tape guide. The reel spring (16) has a generally rectangular shape with first and second parallel edges extending substantially along its entire length. A flat, central base portion of the spring is bounded by a pair of transition portions which extend at an angle out of the plane of the base. A pair of outer end portions set at a sharper angle to the base complete the spring configuration. A polypropylene slack limiter (76) applies a preloaded tension on the magnetic tape. The polypropylene eliminates the need for laminating a separate bearing material to the slack limiter. The tape guide has a semi-cylindrical, stainless steel insert (94) attached to a plastic mounting core (92). The core is fastened to the cassette housing.

Abstract: In a cipher system used in trasmission or storage of digital data, the encipherment section comprises a first modulo-2 adder (108) for adding, bit by bit, the k-bit contents of a first shift register (106) storing latest k bits of ciphertext information and the k-bit contents of a first register (107). The k-bit output of the first modulo-2 adder is expanded into m × n bits, which are sotred in a second register (110), and extracted in sequence, a set of n bits at a time. Each set of n bits is converted into a single bit. A second modulo-2 (113) adder adds the 1 bit output to the contents of a third register (112) or bistable means, which stores the output of the second adder. A fifth register (115) or bistable means stores plaintext information input through the input terminal. A third modulo-2 (103) adder adds the output of the second adder to the contents of a register or bistable means storing plain text information to produce ciphertext information. A sixth register (104) or bistable means stores the output of the third adder. The contents of the sixth register or bistable means are fed back to the first shift register (106), and are also output as ciphertext information.
