Abstract: In connection with an information processing network (16) in which multiple processing devices (18,20,22,24) have individual cache memories and also share a main storage memory(28), a process is disclosed for allocating multiple data operations or tasks for subsequent execution by the processing devices. A plurality of task dispatching elements (TDE) (96-106) forming a task dispatching queue (TDQ) 92 are scanned in an order of descending priority, for either a specific affinity to a selected one of the processing devices, or a general affinity to all of the processing devices. TDEs with specific affinity are assigned immediately if the selected processor is available, while TDEs of general affinity are reserved. TDEs with a specific affinity are bypassed if the selected processor is not available, or reserved if a predetermined bypass threshold has been reached. Following the primary scan a secondary scan, in an order of ascending priority, assigns any reserved tasks to the processing devices still available, without regard to processor affinity. Previously bypassed tasks can be assigned as well, in the event that any processor remains available. A further feature of the network is a means to reset the processor affinity of a selected task from the specific affinity to the general affinity. Resetting is accomplished through an assembly level instruction contained in the task, and either can be unconditional, with reset occurring whenever the task is executed on one of the processing devices, or can occur only upon the failure to meet a predetermined condition while the task is executing.

Abstract: The invention is based on the object of specifying a simple and economical digital modulator by also using circuit sections which are needed for the frequency generation, in any case. The object is achieved by the fact that the output of, for example, a voltage-controlled crystal oscillator (VCXO) is connected to the input of a fixed divider, in that the output of the fixed divider is connected to the input of an adjustable divider which can be initialised jointly with a discriminator and a second adjustable divider, that the first adjustable divider is connected to an input of the discriminator, that the other input of the discriminator is connected to the output of a voltage-controlled oscillator (VCO) via the second adjustable divider, in that the output of the discriminator is connected to one input of a summing element ( SIGMA ) via a loop filter, in that the output of the summing element is connected to the VCO and that the output signal can be picked up at the output of the VCO. A preferred field of application is its use in land mobile radio. The drawing shows the PLL frequency conditioning for a land mobile transceiver (Figure 1). <IMAGE>

Abstract: The invention relates to an improved artificial digital neuron, an enhanced artificial neural network architecture together with a reduced training neural network training algorithm. The digital neuron comprises an n bit input one bit output device utilising a random access memory having 2" locations of one bit each. The neuron is programmed by the network training algorithm with the neuron fire state (on or off) in accordance with the synaptic weights allocated to the input code combination pattern for that neuron within the neural network. The digital neuron operates as a look-up table device deriving the neuron firing state, for each n bit digital code pattern applied to its input paths, from the random access memory location identified by the digital code pattern. The synaptic weights allocated to each digital code pattern for a particular neuron in the network cause the neuron to provide as an input correlation function or an interconnect function. The network architecture is based upon digital neurons providing either correlation or interconnection functions allowing a reduced interconnection arrangement where the output of each neuron in the input and hidden layers is connected only to an input path of a corresponding or immediately above or below neuron in the next layer. The training algorithm maps each pattern (as a function or interconnect) into neurons that lie on the path between a positive input (1) and the network output.

Abstract: An antenna for reception of signals in a plurality of frequency bands employed in portable and vehicular communications is constructed of a dielectric layer (34) disposed on a metallic plate (28) which serves as a ground plane. Microstrip antenna elements in the form of a planar radiator (24;24A;112;120;126) encircled by a loop radiator (26;26A;26B) are disposed upon the dielectric layer (34;34,134,132). A rod radiator (22,22A) oriented normally to the plate extends through the planar radiator and the dielectric layer, and is surrounded by a dielectric cylinder (44) which insulates the rod radiator from the planar radiator and the plate (28). The planar radiator may be configured as a patch radiator, a spiral radiator, or a crossed dipole radiator. Also, one or more additional layers of patch radiator elements (128,130) may be stacked upon the patch radiator to provide a stacked microstrip radiator. Terminals (54,56) are positioned about the planar radiator for extracting orthogonal components of a circularly polarized electromagnetic signal. All radiators are smaller than approximately one-half wavelength of the shortest wavelength signal to be received by the antenna. The antenna can be used for receiving vehicular signals such as telephony, keyless door lock operation, ground positioning satellite signals, as well as AM/FM radio.

Abstract: A point-to-multipoint communication system is presented to enable a reliable, high quality communication using multiplexed optical signals between a central office equipment (100) and a plurality of subscriber's equipment (300,400,600). The system is provided with a plurality of office transceivers (110,120) in the central office equipment (100), and the each of the subscribers is provided with at least one subscriber transceiver (310,320; 410,420; 620). The system is designed so that a redundancy system is built-in by providing one of either the office transceivers, a plurality of subscriber's transceivers or the optical connection device, to connect the two sets of transceivers at all times. One of these redundancy systems provides an operating connection between each of the office transmitters which are connected to the office transceivers and each of the subscriber transmitters which are connected to the subscriber transceivers. Therefore, when a malfunction occurs somewhere in the optical network, the least number of the malfunctioning components need to be switched over the the normally functioning system to maintain continued communication services. The present communication system is designed with the least number of active components, therefore, the failure probability is significantly decreased, and repairs if necessary can be preformed quickly. The overall effect of the present system is that interactive point-to-multipoint communication services of high quality and reliability are provided at reasonable cost.
