Abstract: The device serves to make constantly cooled drinking fluid available at a tap device (12). The pipe (21, 22), which runs from the storage container (15) to the tap device (12), is guided through a generally available ice-cube maker (11). In spite of the lower temperature prevailing in this, the temperature of the fluid remains positive even in the event of long periods of non-operation of the tap device (12). Advantageously, the pipe (21) coming from the storage container (15) is connected to the input (28) and the pipe (22) running to the tap device (12) to the output (29) of a cooling plate (19) lying in the ice-cube maker (11). <IMAGE>

Abstract: A data regenerative system adapted to receive data signals transmitted with the Non-Return-to-Zero mode comprises a comparator (10) for comparing the voltage level of the received data with a variable threshold to generate a digital comparator output. D-type flip-flops (DFF1, DFF2) are arranged to receive the comparator output to generate first and second pulses respectively in response to a data strobe clock pulse. The time difference between the first and second pulses is detected by a first subtractor (21, 22, 23) to generate an error voltage which is applied to the comparator (10) as its threshold to keep the crossing points of the eye pattern of the received signal aligned on the threshold level. A variable width monostable multivibrator (MM) is responsive to synchronization pulses to generate the data strobe clock pulses with a duration that is a function of an output of a second subtractor (26, 27, 28) representing the difference between each period of the first and second pulses and one-half period of a third pulse generated by a D-type flip-flop (DFF4) in response to the leading edge transition of the output of the monostable multivibrator (MM) in the presence of the first and second pulses. Output pulses are regenerated in response to the output of the monostable multivibrator in the presence of the comparator output.

Abstract: The data processing system handles thirty-two bit logical addresses which can be derived from either sixteen bit logical addresses or thirty-two bit logical addresses, the latter being translated into physical addresses by an address translation unit 14. The system includes an instruction processor 12 for decoding macro-instructions of both a basic and an extended instruction set, each macro-instruction containing in itself selected bit patterns which uniquely identify which type of instruction is to be decoded. The decoded macro-instructions provide the starting address of one or more micro- instructions, which address is supplied to a micro-instruction sequencing unit 13 which appropriately decodes a selected field of each micro-instruction to obtain each successive micro-instruction. The system uses hierarchical memory storage using eight storage segments (rings), access to the rings being controlled in a privileged manner according to different levels of privilege. The memory system uses a bank of main memory modules 16 which interface with the central processor system via a dual port cache memory 18, block data transfers between the main memory and the cache memory being controlled by a bank controller unit 18.

Abstract: A sweep generator (10) for producing a circular raster (16) of curved scanning lines (18) on the target surface of a video camera is disclosed. Each curved trace follows a substantially circular path through a scanning angle of 360 The circular raster is generated by horizontal and vertical scanning signals (28, 30) which are synchronized with the horizontal line frequency of a video receiver. The horizontal scanning signal (28) is characterized by a constant amplitude component (28A) followed by a sine wave component (28B), and the vertical scanning signal (30) is characterized by a composite waveform including a constant amplitude component (30A) followed by a sine wave component (30B) which is shifted 90° in phase with respect to the sine wave of the horizontal scanning signal.The constant amplitude components of each composite waveform are synchronized with the horizontal blanking pulse (32) which occurs during horizontal retrace of the scanning beam in the receiver, and the phase shifted sine waves are synchronized with the forward trace of each horizontal line in the receiver. This produces a one-to-one correspondence of each circular trace in the video camera with each horizontal forward trace in the receiver. The composite scanning signals are amplitude modulated by a sawtooth signal (36, 38) which is synchronized with the receiver field frequency, thereby producing the circular raster of concentric scanning lines. According to a preferred embodiment, each composite waveform is produced by a read only memory (ROM) (40,42) which is synchronously cycled at the line frequency while driving a digital-to-analog converter (44, 46). The modulating signal is generated by a sawtooth oscillator (60) which is synchronized with the receiver field frequency.

Abstract: A method is described for classifying a document as bilevel or continuous gray scale for the purpose of selecting a compression algorithm for efficient transmission and/or storage of the digitized image of that document. 
     After the document has been at least partially scanned with a gray scale video camera and digitized pel values have been stored, a pel distribution table or histogram is formed. The histogram is analyzed to determine whether there is a peak region having at least 50% of the total number of pels. If 
     there is not, the document is classified as continuous gray scale. If such a region is found, tail (T) and tail factor (TF) values are computed. The relative magnitudes of these values and the algebraic sign of the T value are used to classify the scanned document as continuous gray scale, 
     white on black or black on white. Once the document is classified, an optimum data compression algorithm can be selected.
