Abstract: Digital processing systems and methods of hydroacoustic pulse communications in offshore seismic exploration systems provide more efficient surveys with less critical equipment. Thus hydroacoustic transceiver transducers towed in a set of streamers behind a vessel are accurately positioned under variable operation conditions with a geodetic reference point for more efficiently and accurately monitoring echo points for seismically identifying underwater formations. Spacings between transducers are found by calculating from pulse arrival times the transit times of hydroacoustic pulses. Predetermined pulse shapes and carrier frequencies above 40kHz are accurately determined upon receipt by digitally sampling waveshapes to determine shape and timing the reception of identified pulse shapes at transducers which are transmitted from other transducers for computing separations between sending and receiving transducers. Pulse transit time averaging avoids precise synchronization for simpler apparatus. The carrier frequencies and associated high pass filters for received pulses eliminate hydroacoustic noise. The digital pulse sampling and timing techniques simplify communications with associated data processing systems for seismic analysis and provide compact on-location electronic systems coupled to the transducers.

Abstract: In a digital display system (10) including a stroke scanning mechanism, a method which comprises the steps of displaying symbology (100) and increasing (116) or decreasing (108) the number of symbols displayed, including the null symbol depending upon comparisons (104) of actual stroke time to a predetermined stroke time limit. The symbology is initially displayed by stroke scanning. The actual stroke time for displaying the symbology is measured. The actual stroke time is then compared (104) with the predetermined stroke time limit to ascertain whether or not the time limit has been exceeded. If the stroke time limit is not exceeded and a null symbol is not present in the symbology displayed (114), a null symbol is added (118). If the stroke time limit is not exceeded (104) and a null symbol is present in the displayed symbology (114), the number of symbols is increased (116). If the stroke timing limit is exceeded (104) and a null symbol is present (106) in the symbology displayed, the null symbol is removed (110). If the stroke time limit is exceeded (104) and the null symbol is not present (106), a null symbol is added (112) and the number of other visible symbols is decreased (108).

Abstract: Method and apparatus for error recovery in primary storage is provided by backup storage that stores a complete copy of primary storage. When a parity error is detected, the backup storage is used to replace data in the primary storage or the parity of primary storage. This apparatus is controlled by a processor controller which makes this replacement by comparing the primary storage, backup storage, and the primary parity storage. If after re-execution of the operation errors are still detected, the processor controller copies the data from primary storage to a secondary storage and retries the operation.

Abstract: An image processing apparatus includes a CPU which executes a program read from an external storage unit, and a video processor. In the video processor, color data of moving picture characters and color data of still picture characters are respectively outputted from a moving picture data generating circuit and a still picture data generating circuit. Both the color data are applied to a main/subsidiary data selection circuit which outputs the color data as main image data and subsidiary image data. An arithmetic circuit executes an arithmetic operation to obtain a mean value of both the color data. A video signal producing circuit converts the mean value of the color data from the arithmetic circuit into a video signal which is then applied to a display.

Abstract: An image binarization system that makes it possible to read documents of normal printed quality without using special high-quality paper, and also enables high-speed, continuous image processing to be implemented with a minimum of memory capacity. Image signals acquired by a scanner are binarized by first and second binarization sections. The first binarization section uses a floating threshold to binarize halftone image regions in the main, inner part of the document, while the second binarization section uses a fixed threshold to binarize the document edge portions. The second section may be employed to identify document edges and direct signal processing by the first binarization means to portions of the document of known interest.

IPC: H04M3/58

Abstract: A connection request which is addressed to a particular terminal (KE-D) is simultaneously signalled at at least one further terminal (KE-C). These terminals preferably belong to a group of terminals integrated in the communication system, which have so-called key functions. If the call is accepted by a terminal (KE-C), it is possible, after a connection has been set up to the other terminal, if this terminal is ready to accept the call, automatically to establish a connection between this terminal and the original calling terminal (KE-A) by operating a special key (ST). At the same time, the connection set up between the two first-mentioned terminals is released by this means. This switching-through of the connection to the calling terminal (KE-A) is similarly possible if this terminal, in turn, has transferred another terminal (KE-B), with which it previously had a call connection, into the hold state. Since for the connection between the associated terminals, a connection memory which is independent of the said other connections is loaded and read out, these connection memories must receive information items which, at the most, are related to three terminals. In spite of the possible involvement of a total of four terminals, no elaborate procedures therefore need to be provided for administering the entries due to changing switching conditions for the terminals. Function sequences are possible which, in their final result, correspond to those of a second call-back capability. <IMAGE>

IPC: G06T5/20

Abstract: For noise reduction in a two-dimensional image it is sampled according to a regular array of window sampling positions. The image function is then subjected to multiplication by a window function and conversion to a weighted sum of polynomials according to ascending order. If the next-to-lowest order coefficient signals a sufficient intensity variation in the window, all coefficients are used for subsequent inverse polynomial transform. Otherwise, predominantly only the lowest order coefficient is used therefore. In a cascaded organization, the lowest order coefficient is viewed as itself representing the image information and likewise processed in a forward-inverse polynomial transform organization with respect to an upscaled-size window. The result is then used in a next lower cascade level in lieu of the unprocessed lowest order coefficient itself.

Abstract: The video signal input is converted to high-speed reproduction data by a high-speed reproduction data encoder 1. The video signal input is converted to high-speed reproduction data by a formatter 2, which formats the high-speed reproduction data so that the same data is recorded to n tracks; this becomes the recorded data. After the recorded data is input to an error correction encoder 3, it is decoded by a decoder 4 and recorded by a recording head 5 to the magnetic tape 6. During reproduction, the recorded data is reproduced by reproduction head 7 from the magnetic tape 6, and decoded by decoder 8. The decoded data is then error corrected by an error correction decoder 9, and then input to a deformatter 10. The deformatter 10 separates the normal reproduction data from the high-speed reproduction data, and separately outputs both data types. During normal reproduction, the normal reproduction data is output by a switch 13; the high-speed reproduction data is decoded to video data by a high-speed reproduction data decoder during high speed reproduction, and output.
