Granted: 1983-11-22
Abstract: Abstract of the Disclosure A graphic arts image comprising a plurality of regions, each region having a characteristic multilevel intensity, hue, texture or the like, is sampled and coded using samples along two consecutive scan lines.  Individual code words are generated for the beginning, or head, of each run defining the start of A vein or boundary of a region of contiguous like-valued samples along each line and other code words are used for connecting information relating to samples on adjacent lines defining continuations of the boundary for the same region.  Other code words identify the characteristic intensity or the like of the region, and a final type of code word identifies the end of the vein.  Because the present method and apparatus advantageously codes each internal boundary between adjacent regions only once, an increase of efficiency by a factor approaching two is realized over techniques previously used.

Abstract: METHOD TO FIX LIQUID FUELS WITH DILUENT    GAS FOR A GASEOUS FUEL BURNER             ABSTRACT OF THE DISCLOSURE       Apparatus to burn liquid fuels in a gaseous fuel burner, which includes preparatory apparatus for the atomization of liquid fuel oil preferably by a diluent gas, and the heating of the fuel droplets and diluent gas so as to completely vaporize the liquid fuel.  If atomiza-tion is by other means, diluent gas is added prior to vaporization heating.  The resulting oil vapor-diluent gas mixture then goes to a burner which utilizes the central orifice of a conventional gas burner.  Primary air is induced into the burner tube due to the high velocity of jets of oil vapor-diluent gas.  The diluent gas permits low vapor pressure of oil vapor and thus low operating temperature.  For the use of gaseous fuel, the same burner is utilized.  The diluent gas can be preferably any non-combustible and non-oxygen containing gas.

Abstract: TIMING CIRCUIT AND METHOD FOR A TRACK FOLLOWING SERVO IN A         DATA STORAGE SYSTEM                  ABSTRACT OF THE DISCLOSURE    A timing circuit for a track following servo system wherein an odd servo track having a series of prerecorded odd dibits thereon and an adjacent even servo track having a series of even dibits prerecorded thereon are moved with respect to a servo head to induce in the servo head signals that vary with the occurrence of the dibits and have an amplitude representative of the lateral position of the servo head with respect to the servo tracks.  The servo head and its associated preamplifier produce a first signal having portions from both odd and even servo tracks and a second signal that is the inverse of the first signal.  The first and second signals are processed by parallel identical circuit paths to generate a clocking signal that times the remainder of the data storage system in synchronism with the spacing of dibits on the servo tracks.  Each of the parallel identical circuit paths includes a circuit for discriminating between true dibits and spurious noise signals on the servo tracks, a counter circuit for passing only those dibit pulses that occur within a given time interval after the next preceding dibit, and a circuit for pro-ducing a timing pulse at a specified time after the preceding pulse to maintain system synchronization even in the absence of a dibit on one of the tracks.

Abstract: ABSTRACT      A data processor input/output controller which is particularly useful as a microcontroller for the transfer of data between a host processor and one or more peripheral input/output devices in a digital data processing system. This input/output (I/O) controller is a subchannel control-ler for offloading a goodly portion of the subchannel control function from the host processor.  This I/O controller includes a microprocessor for assisting and supervising the controller internal operations.  Also included in the controller is an automatic high-speed data bypass mechanism whereby data may be transferred from the host processor to the I/O device or vice versa without having to pass through the microprocessor and without requiring any intervention on the part of the microprocessor during such automatic transfer.  Provision is made for enabling the microprocessor to perform other functions, such as the presentation of interrupts to the host processor and the servicing of addi-tional I/O commands from the host processor concurrently with the transfer of data via the automatic bypass mechanism. This capability is particularly useful where two or more I/O devices are connected to the controller.  The automatic bypass mechanism is constructed to communicate with the host processor in a cycle steal mode. A look-ahead mechanism is provided for more quickly issuing the cycle steal requests to the host processor when operating in the automatic bypass mode.

Abstract: METHOD AND APPARATUS FOR CONVERSION OF SIGNAL INFORMATION BETWEEN ANALOG AND            DIGITAL FORMS                         ABSTRACT          Signal information is converted between analog and digital form in a two-step process  employing con-version apparatus having stable, but not necessarily highly accurate components.  The component tolerances on such conversion apparatus are much greater than those normally allowed on conventional conversion apparatus of equal accuracy.  In an A/D conversion, an analog signal is first converted into an (n+m)-bit digital word in a special purpose digital code unique to the specific A/D conversion apparatus.  The (n+m)-bit word is then translated into an n-bit word in binary digital code in accordance with a predetermined relationship therebetween.  In a D/A conversion, an n-bit digital word in a binary digital code is first translated into a corresponding (n+m)-bit digital word in the special purpose digital code.  The (n+m)-bit word is then con-verted into an equivalent analog signal; the latter step being performed by a conversion apparatus unique to the special purpose digital code.  A plurality of A/D and D/A converters suitable for use with the present invention are disclosed.  A number of converter calibra-tion techniques are also disclosed.
