Abstract: According to a method of detecting an acoustic signal, first and second sound receiving units are located at substantially the same position and are used to output signals having different target signal power to noise power ratios (S/N ratios). When a difference between the powers of the signals output from the first and second sound receiving units or a ratio of the power of the signal from the first sound receiving unit to that from the second sound receiving unit in a given period falls within a predetermined range, reception of the target signal within the given period is discriminated. The first sound receiving unit is an adaptive microphone array capable of controlling directivity characteristics in correspondence with a noise position.

Abstract: For automatic pattern recognition, a neural network has an input layer (IL) (two-dimensional field consisting of MxN elements, M = number of characteristic vectors, N = number of coefficients per characteristic vector) which is divided into overlapping pattern segments (LHxLV, with LH<M, LV<N), neighbouring segments overlapping partially at least in one direction. Each neural element of a downstream hidden layer (HL) is formed from a differently wieghted sum value of the amplitudes of a segment of the input layer (IL). The hidden layer (HL) is then fully networked with a one- dimensional output layer (OL), that element of the output layer which has the greatest sum value corresponding to the pattern to be recognised. <IMAGE>

Abstract: An inter-processor interrupt mechanism is implemented in a shared-memory multi-processor system. A dedicated halfword for each processor in said multi-processor system is provided in the shared memory restricted in use to the generation and control of inter-processor interrupts. No data in any dedicated shared-memory location can be altered by any processor unless it has "captured" the location by executing a test and set halfword instruction and a captured shared-memory location being released only by executing a store halfword instruction. An address comparator and a zero detector are added as adjunct operations to read-modify-write logic of each processor's memory interface. When any instruction is executed and its operand address agrees with that contained in the address comparator, an inter-processor interrupt request is generated if zero is not detected on all low-order data being written to memory. If a zero is detected on all low-order data being written to memory, the inter-processor interrupt request is removed.

Abstract: In a learning machine with multi-input single-output circuits (18, 19, 20) connected in a hierarchical structure which sums up weighted input signals and subjects the sum thus obtained to a non-linear processing to provide an output signals, each weight is changed (16, 65) to provide a desired value of each output signal in learning. Using, as a direction of changing the weight, a conjugate gradient direction is used in place of the most sudden drop direction which has been conventionally adopted can reduce the time required for the learning. Also dynamically setting, as a learning parameter, an optimum value in place of a fixed value which has been conventionally adopted can reduce the time required for learning. Moreover, in calculating errors for plural learning parameters relative to a certain weight changing direction, a product-sum of the input signals and weights in a secret layer (22) and a product-sum of the input signals and the weight changing direction in the secret layer are stored (77) so that the number of operations of acquiring outputs from the secret layer thereby to greatly reduce the time required for learning. Furthermore, if it is detected (92) that the learning has been fallen into an unsuitable state where further advancing the learning cannot effectively reduce the errors, the weight are adjusted to resume the learning thereby reducing the time required for learning.

In the process, the mass-flow ratio, i.e., the ratio of the mass-flow rate of combined coagulating liquid to mass-flow rate of the filaments, is greater than about 250, preferably greater than about 300, and the momentum ratio of jetted to overflowing coagulating liquids of greater than about 6.0 is employed. Also, the average linear velocity of combined coagulating liquids in the spin tube is less than the velocity of the filaments exiting from the spin tube.

To optimise the operating mode of a delivery device of this type, the invention proposes that the drum outer surface have a radially outward-directed annular collar (R) in alignment with the plane of each of the partition walls (47, 48).

The control circuit, in turn, is driven by a comparator (K) which compares the output voltage of the data driver or of a similar reference data driver (RT) with a reference voltage (UR) and causes the control circuit to connect or disconnect part-current paths when the output voltage of the data driver deviates from the reference voltage. <IMAGE>

Abstract: A liquid crystal display (10) is provided with a source (23, Fig. 2) of backlighting (24) which augments reflected (25) incident light to provide increased contrast. A liquid crystal cell (17) which does not contain dye, but becomes clear when a field is applied, is sandwiched between a liquid crystal cell (14) with a dye and the source (23). The cell without dye is electrically connected so that when the front liquid crystal cell (14) is turned ON to make selected portions of it transparent, the back liquid crystal cell (17) is OFF so that corresponding portions of it are highly reflecting. No voltage is allowed to be applied across nonselected portions of the front liquid crystal and a voltage is applied across corresponding nonselected portions of the back liquid crystal making the nonselected portions of the back liquid crystal clear, producing a display of high contrast. The source (23) at the rear of the back liquid crystal cell is a clear plastic wedge which is edge lighted. The edge lighted wedge only appears bright in the areas where the voltage on the back liquid crystal cell (17) is OFF or not applied thereto.
