Patent EP-0408130-A2 (EP)
Inventor: URBANSKY RALPH DIPL-ING
IPC: H04J3/07
Filed: 1990-07-06
Abstract: The invention relates to a stuffing decision circuit (24) for an arrangement for the bit rate adaptation of two signals. The bit rate adaptation circuit arrangement contains, among other things, a flexible memory (4) into which the data of a first signal are written in parallel in groups of n bits each and are read out again in parallel. The flexible memory (4) is followed by a selection matrix (5) for inserting the stuffing bits. The writing process is controlled by a write counter (12) and the reading process is controlled by a read counter (13). A subtracting circuit (9) forms the difference of the counts. So that the stuffing decision circuit (24) can be constructed in CMOS technology even with bit rates of the order of magnitude of 140 Mbit/s, it is provided to connect together the subtracting circuit (9), a controller with I characteristic (17), a pulse distributor circuit (20) and the read counter (13) to form one control loop. When a synchronisation pulse (25) applied from outside occurs, the pulse distributor circuit (20) carries out at least one of the following operations:   a) it outputs a stuffing information item when a carry has occurred between the last and the instantaneous synchronisation pulse at a predetermined binary position in the output signal of the controller (17), b) it outputs a signal to the selection matrix (5) for inserting a stuffing bit, c) it outputs a signal to the read counter (13) which stops it for one clock cycle when the number of stuffing bits inserted up to the instantaneous synchronisation pulse exceeds an integral multiple of n.   <IMAGE>

Abstract: A signal processing method for efficiently searching an optimum solution in a neural network by including a term of a nonlinear resistance in an equation of motion and changing such nonlinear resistance periodically. According to the method, the range of absolute values of connection weigths between units in the neural network is limited by the equation of motion, hence preventing a prolonged search time that may otherwise be caused by excessive extension of the search scope beyond the requisite. A plurality of patterns are previously embedded or stored in the neural network and, upon input of a predetermined key pattern, the nonlinear resistance is changed periodically to recall a pattern similar to the key pattern, whereby any desired pattern can be searched or retrieved with rapidity and facility out of the complicated patterns. A process of calculating the next position of an articulated robot (12) corresponding to an optimum solution is repeated while periodically changing a nonlinear resistance included in another equation of the positional energy of the robot (12), thereby acquiring the data of the robot path up to a desired goal.

Abstract: A synthesizer (30) is placed in standby mode when a standby portion of a control register (47) is set. Once standby is activated, any detectors (33, 33') and counters (42, 43, 44) are inhibited. The inputs and outputs are reconfigured so as to minimize current drain and to stabilize the VCO (12) control voltage. Recovery from standby is accomplished in two phases. The first phase is started by the receipt of a terminate standby signal. This enables the inputs and starts the counters (42, 43, 44). The second phase is activated when a signal is received from a feedback counter (43) indicating it has completed a cycle. This causes the preset data to be loaded into the reference counter (44). The counters (42, 43, 44) are then synchronized; the detector (33) is initialized; and the detector (33) output is enabled. The device (30) also controls an output lock detector (55) and reference frequency signal during the standby mode. The system (30) is also compatible with variable modulus prescalers (11).
