Abstract: A method of, and system for, data transmission over a time division duplex channel in which at least one duplex voice channel constituted by a pair of non-adjacent time slots (or physical channels) in a succession of time frames is allocated for effecting a data transaction between a first and a second station, one of said pair of time slots (or physical channels) being normally designated for unidirectional transmission of data in a first direction between the first and second stations and the other of the pair of time slots (or physical channels) being normally designated for unidirectional transmission of data in a second direction, opposite to the first direction. The system comprises means for determining that either of the time slots (or physical channels) of a duplex voice channel will not participate in, or is not participating in, the transmission of useful data because the data transfer is largely asymmetric and for releasing the non-participating time slots (or physical channels) and making them available for other unidirectional signalling, such as the parallel transmission of data packets in the current data transaction, retransmission of corrupted data packets, or the parallel transmission of data packets in another, largely asymmetric data transaction.

Abstract: For sampling a modulated carrier, a zero-crossing detection means having two independent control loops, a first loop for a zero-mean threshold control and a second loop for AGC control includes an IF sampler (14) that quantizes the received spread spectrum signals at IF and samples at a number of quarter cycle intervals to allow sampling in sequence of the in-phase (I) and quadrature-phase (Q) components. The output of the IF sampler (14) is two bits, a sign bit and a magnitude bit. The zero-mean threshold control loop (16, 18) using only the sign bit of the I and Q samples sets a threshold level (TO) to detect the zero-crossings of a received waveform. Two magnitude threshold levels (TO + D1, TO-D2) are set at fixed offsets from the TO threshold level. A normalized statistical accumulator (26) using the magnitude bits of the I and Q samples determines the AGC control level for a fixed percentage of outside threshold crossings of the most significant magnitude bit. The I and Q samples are aligned in time by an aligner (16), and every other pair of I and Q samples are inverted in a baseband demodulator (20) for digital demodulation of the IF samples to baseband. The baseband samples are provided to a signal processor (24) for generating range and range rate information.

Abstract: Each unit of a daisy chain of separate and independent multiplexing units (10, 12,14) is arranged to accept a group of local audio inputs (Audio 1 - Audio 8) and an additional input (18, 20, 22) from a prior unit in the chain to time division multiplex the additional input with the local units. Each unit provides a single serial bit stream output (20, 22, 24) which comprises the additional input to the next identical multiplexer unit in the chain. The next multiplexer unit time division multiplexes all of its inputs to provide a single output which includes a serial presentation of its own local inputs and the local inputs of the preceding multiplexer unit of the chain. This single serial output of the next multiplexer then forms the additional input of a still further multiplexer unit of the chain, which itself may have its own local inputs. The third multiplexer unit provides a single output that is a serial presentation of the local inputs of all three multiplexers. Additional multiplexer units can be added to the chain as may be necessary or desirable to accommodate reconfiguration of systems with which the multiplexers are used. For serial presentation of the local inputs of the several multiplexers units, system timing (84) provides a time frame, common to all units, that is subdivided into a number of subframes (subframes 1,2,3), which number is equal to the maximum number of multiplexer units that is expected to be employed in the chain. Each individual multiplexer unit of the chain is assigned a specific one of the subframes which uniquely contains data of its local inputs. For multiplexer units at the beginning of the chain only those subframes at the beginning of a frame may have data, whereas other subframes contain no data. For a final multiplexer in the chain, where the number of multiplexer units is equal to the number of subframes, all subframes contain data, with the data of each subframe being unique to the local inputs of the single individual multiplexer unit corresponding to the particular subframe.

Abstract: A graphics plotter for drawing a series of connected vector lines forming a plot. The plotter has a motor control for controlling motors which drive a pen to move relative to a medium at a variable velocity in a plane defined by a major axis and a minor axis perpendicular to the major axis. The motor control determines a minimal nonzero terminal velocity of the pen along the major axis at a point at which a maximum change in direction occurs. The motor control has a program for determining a minimal nonzero optimal velocity at the point of maximum change in direction. The minimal nonzero optimal velocity is the junction of a ramped-down optimal velocity preceding the point of maximum change in direction and a ramped-up optimal velocity succeeding the point of maximum change in direction. The motor control also includes a double integrating filter implemented in the sampled domain for limiting the acceleration of the pen along the major axis at the point of maximum change in direction to a discrete value such that the difference between the actual pen trajectory and a desired pen trajectory is an amount less than or equal to a predetermined acceptable error.

Abstract: In response to a switching control signal from an aspect ratio switching circuit (6), a video signal having a different degree of horizontal compression and an aspect switching control signal are fed to the view finder (3), a magnetic recording/reproducing circuit (4) and an external device (5). The magnetic recording/reproducing circuit (4) simultaneously records the video signal and the switching control signal. In reproduction, the magnetic recording/reproducing circuit (4) outputs the recorded switching control signal. In response to the switching control signal, the external device changes the deflection angle of a built-in display circuit to switch the aspect ratio of the displayed video signal. The electronic view finder receives a video signal having a different horizontal compression degree, and at the same time receives the aspect ratio switching control signal to operate the switching circuit in the view finder (302) to change the deflection angle and hence switch the aspect ratio to display the image.

Abstract: During connection signalling, terminals (EG) transmit events to the communication system which, in turn, can send information items to the terminals, for example for indication on a linear display. A high-priority event protection program module (AN) notes incoming events in terminal-individual event memories (AZS). A low-priority arbitration program module (AR) successively takes one event in each case from the event memories and initiates the processing of the program module designated by this event. The output information items formed by the program modules are stored in terminal-individual information output memories (INFAS) which consist of a first and second part-memory (TS1, TS2) for terminals with ringing-tone activation process. The first part-memory is used for storing a ringing-tone off information item. From the event protection program module, a part-information is in each case transmitted to the terminal from the information output memories. To be able to switch off the ringing signal immediately after the establishment of a connection to a terminal, the information stored in the first part memory (TS1) is in each case transmitted with priority. <IMAGE>
