Code Transmitters Patents (Class 178/79)
  • Patent number: 9479369
    Abstract: An alternative type of vector signaling codes having increased pin-efficiency normal vector signaling codes is described. Receivers for these Permutation Modulation codes of Type II use comparators requiring at most one fixed reference voltage. The resulting systems can allow for a better immunity to ISI-noise than those using conventional multilevel signaling such as PAM-X. These codes are also particularly advantageous for storage and recovery of information in memory, as in a DRAM.

    Abstract: The through metal communication system sends messages by tapping on metal barriers, such as pipelines, bulkheads, and the like. A robotic element attaches itself to a metal barrier, wall, pipe, and the like. A piezoelectric tapping device is attached to the robotic element and can tap an encoded message onto the metal. The robot preferably includes a piezoelectric actuator, a microcontroller to convert text/information to Morse code, and a power source for the actuator. The messages are retrieved and interpreted by a remote transducer connected to a computer or microcontroller.

  • Patent number: 7295922
    Abstract: A method of producing an interactive map using a computer system. The method includes determining graphic data indicative of a visible representation of a map of a geographic area and determining an identity. The computer system then generates coded data indicative of the identity and of a plurality of reference points of the map, and records an association between the identity and a page description, the page description being indicative of a layout of the coded data and the graphic data. The computer system then causes the map to be printed by printing of the graphic data and the coded data onto a surface using the layout.

  • Patent number: 5142277
    Abstract: A train communication and control system is described having the cars of the train connected by a two-wire train line running continuously from car to car. Any car may be selected to be a master unit. The selection of one car as a master unit disconnects the power sources of all other cars from the train line, leaving the master unit power source as the sole power source for the line. The master unit communicates with each other car by causing a high voltage ("mark" state or logic one) or a low voltage ("space" state or logic zero) to be on the train line. Each non-master car can receive a communication from the master unit, or can transmit to another car by applying a low impendance across the train line to change from a "mark" state to a "space" state. The power source consists of a voltage regulator with precision constant current limit.

  • Patent number: 4511758
    Abstract: In a message communication system and process, a character string with a plurality of characters is encoded into a compact code, which is transmitted to a reception side. At the reception side, the compact code is decoded to an original character string. Thus, the amount of information to be transmitted is fairly reduced as compared with the transmission in which each character is encoded. Preferably, a combination of a word and a `space` code following the word is encoded to a single compact code. The compact code may also encode a combination of a plurality of words. Some particular control codes are defined for converting a small character to a capital character, or vice versa, and designating special code like period ".", quotation mark "?", etc.

  • Patent number: 4333091
    Abstract: A system is disclosed for utilizing command buffers in a microprocessor controlled electronic code keyer for storing, rather than text to be transmitted, command strings for keyer operation. The command string is defined by a series of keypad closures for selecting a sequence of text buffers to be transmitted. In addition, the command buffers may be used during automatic text transmission to selectively change keyer parameters such as the speed of character transmission, inter-character and inter-word spacing, dot-to-dash-to-space ratio, or the number of times the contents of a text buffer will be automatically repeated. The use of text and command buffers permits the formation of essentially errorless Morse code transmissions, substantially enhances keyer operating and makes more efficient use of available memory.

  • Patent number: 4292624
    Abstract: The binary coded decimal of a number is selectively loaded into presettable counters. A switching means sequentially connects each of the binary levels of each of the digits comprising the number to an International Morse Code memory addressing a selected segment thereof. A binary counter sequentially addresses each of the bit locations of the selected memory segment thereby serially generating, in Internatonal Morse Code, the digit contained in the addressed memory segment. Upon completion of the code translation of a selected digit of the number, the switching means connects the binary levels of the counter containing the next lesser significant digit to the memory address and the binary counter is recycled. Means are included for selectively deleting the generation of leading zeros of the number and for selectively abbreviating the International Morse Code generation of certain digits comprising the number.

    Abstract: A circuit for producing a pulse succession of long duration from several mutually independently produced synchronous pulse successions of shorter duration in which the output signal is derived as a logical function. Each of the pulse successions of shorter duration is produced by a separate generator and the pulse succession program of each of the generators is determined by a common information carrier, in particular a punched strip. A memory is interposed to take the information which is emitted separately by the information carrier for each of the generators and controls the respective generator. A sensing device is provided for the information carrier to respectively evaluate a portion of the information contained therein, the sensing device being connected to a series-parallel converter having storage facilities for the parallel result to effect adjustment of the individual generators.
