  • Apparatus and method for decoding information
    Patent number: 4382249
    Abstract: An apparatus and method for decoding input signals on four lines to produce an outgoing information stream of binary bits.
    Type: Grant
    Filed: December 22, 1980
    Date of Patent: May 3, 1983
    Assignee: Honeywell Information Systems Inc.
    Inventor: Herbert K. Jacobsthal
  • Apparatus and method for collision avoidance
    Patent number: 4376278
    Abstract: A collision avoidance apparatus having a voltage source producing a predetermined voltage level. A switching network within the collision avoidance apparatus is capable of alternately applying the predetermined voltage level to the communication medium and of applying the voltage level of the communication medium to a logic network. The logic network indicates if the predetermined voltage level and the voltage level of the communication medium are approximately equal.
    Type: Grant

    Date of Patent: March 8, 1983
    Assignee: Honeywell Information Systems Inc.
    Inventor: Herbert K. Jacobsthal
  • Binary to one out of four converter
    Patent number: 4373152
    Abstract: An apparatus and method for encoding information receiving a binary information stream. The apparatus actuates one of four outputs as determined by the last output actuated and the binary level of the binary bit received.
    Type: Grant
    Filed: December 22, 1980
    Date of Patent: February 8, 1983
    Assignee: Honeywell Information Systems Inc.
    Inventor: Herbert K. Jacobsthal
  • Information communication system with collision avoidance
    Patent number: 4345250
    Abstract: An information communication system having several transceivers connected to a communication medium. Each transceiver connected to a collision avoidance apparatus which determines if another transceiver is preparing to transmit on the communication medium by applying a unique predetermined D.C. voltage level to the communication medium.
    Type: Grant
    Filed: December 22, 1980
    Date of Patent: August 17, 1982
    Assignee: Honeywell Information Systems Inc.
    Inventor: Herbert K. Jacobsthal
  • GCR Data write control apparatus
    Patent number: 4201980
    Abstract: This relates to an apparatus for converting raw data into GCR data and for controlling the recording of GCR data on magnetic tape. An ordered series of instructions is stored in a first programmable read only memory (PROM). A second PROM contains a special character table and a code conversion table, and receives raw data. A third PROM stores addresses which are used to access the second PROM and are indicative of whether raw data is to be converted or a special character is to be generated.
