Abstract: A digital audio signal which is subject to sample-to-sample jitter is synchronised with local reference pulses (READ) by the use of a read-write buffer memory (12). Timing pulses at a terminal (80) are associated with the input samples. The input samples are applied through a one-sample latch store (36) to the main memory (12), and the timing pulses are applied by switches (66,68) either directly or after a short delay by a delay element (38) to the write control input of the main memory (12). A phase comparator (24) detects sample-by-sample when the write pulses are near to the read pulses and causes the switches (66,68) to change state in response thereto, and they retain their changed state until a danger of potential read-write contention is again detected when they revert to their original state.

Abstract: A data printing system has a controller (1) which controls the printing of jobs from at least one input unit (2-1, 2-2, 2-N, 5) by a printer (4). When the controller (1) receives a plurality of jobs, it establishes a sequential order of transmission and generates a display signal indicating the times at which the respective jobs will be printed. That display signal may then generate a display at the input unit(s) (3-1, 3-2, 3-N) or at a display (141) associated with the controller (1) itself. In this way, users are given information about the times of printing. The sequence of printing of the jobs may be established on the basis of a priority associated with the jobs themselves and/or on the amount of material currently available for printing by the printer (4) and/or on the maximum capacity of printed paper. Display may be associated with that amount and/or capacity.

Abstract: An emulation system used to debug software for a digital signal process (DSP) (6) includes a built-in digital signal analyzer (18) which operates upon the same digital signals as those presented directly to and outputted by the DSP (6), bypassing the signal converters (4, 8) used to convert an input analog signal to digital format and the output digital signal to analog format. A host computer (12) communicates with the digital signal analyzer (18) via firmware in a control processor (30) and personality board (36), or is alternately connected directly with the analyzer (18). Communications between the digital signal analyzer and the DSP (6) are through the same contact probe (14) as that used for the emulation software. The analyzer may be used to trigger a software function within the emulator (20) based upon the real-time signal from the DSP (6), and is also capable of interpolating between successive digital values of an analyzed signal for display purposes.

Abstract: An image region extraction capable of extracting an image of a significant moving object in a dynamic image accurately and easily at high speed. The operator is required to manually enter the rough boundaries for the significant region in the first two fields of the dynamic image only, and the subsequent extraction operation for each subsequent field of the dynamic image is carried out automatically according to the conjectured rough boundary obtained on a basis of the extraction regions for the two fields immediately preceding that field. The extraction region for the significant region is obtained from the rough boundary on a basis of an original image of a respective field of the dynamic image, and the extracted image of the significant region in each field of the dynamic image is obtained by multiplying the original image of each field and the extraction region for the significant region in each field.

Abstract: An exercise-hardness data output apparatus outputs exercise hardness of an exercise which a user takes, as exercise-hardness data, which can be used for general purposes in the exercise physiology. Using the apparatus, the user can objectively learn the exercise hardness of his (or her) exercise for keeping himself healthy or for developing his physical strength. The exercise-hardness data output apparatus calculates exercise hardness data from counted pulse number of the user and his age, and outputs the exercise-hardness data.

Abstract: In the case of the multiphase switching system (1), each (for example L3) of the phase conductors is arranged in the course of a generator output line (2), which is arranged between a generator (7) and a mains power supply transformer (8), together with a switching apparatus, separated from the other phase conductors, in encapsulation (5) which is insulated by air gaps. This switching system should be able to cope with virtually all the switching, protection and measurement functions occurring in a generator arrangement, despite having a compact and space-saving construction. This is achieved in that the switching apparatus (three position interrupter switch 10) has at least two switching points. A first of these two switching points is arranged between the generator (7) and an output, which acts on the mains power supply transformer (8), of the switching system (1). A second is, in contrast, located between the generator (7) and a power connection (20) to a starting device (21) which is located outside the encapsulation (for example 5) and acts on the generator (7) when the first switching point is open and the second is closed. In the case of a generator arrangement which is equipped with such a switching system (1), it is possible to save a load interrupter switch or interrupter switch (circuit breaker) used for connecting power from the starting device (21) to the generator (7). <IMAGE>

Abstract: An interchangeable pinch valve system (10) is provided with a valve body (20) having a longitudinal dimension which is substantially identical to standard longitudinal dimensions for ball, gate and the like type valves of similar flow path diameter. The reduced longitudinal dimension of pinch valve system (10), as compared to prior art systems, is achieved by a flexible-walled tubular sleeve (50) having a pair of transversely directed folds (60, 62) which provide sufficient sleeve material to enable the pinch closing of the flow passage (52) without substantially stretching the tubular sleeve wall (51). The valve body 20 is provided with a pair of recessed openings (22, 24) formed in the interior of valve body wall (21) in parallel spaced relation transverse to the fluid flow axis of the valve for receipt of the respective folds (62, 60), whereby the tubular sleeve (50) is in contiguous contact with the interior surface of valve body wall (21). This arrangement permits the fluid flow passage to occupy the maximum cross-sectional area of the through passage (25) of valve body (20).
