Definitions

  • This invention relates to paging systems operable with personal portable pocket-sized paging instruments that afford two way communication, and more particularly it relates to keyboard operated paging instruments processing alphanumeric characters for transmission and display.
  • suitable two-way miniaturized pocket-sized paging instruments have not heretofore been available in the art in spite of the significant advantages to two-way digital communication, including: the ability to code and keep messages private, the ability to transmit digital data over trans­mission channels at very high transmission rates, the ability to record communicated messages by storing and printing, the ability to convey critical amounts of data, and the ability to communicate with deaf or mute handicapped persons.
  • This invention provides a pocket-sized portable two-way digital radio communication center with a twelve key keyboard permitting entry of both decimal and alphabetic characters, as well as a large number of commands or instructions.
  • the twelve keys are arranged and spaced for touch typing with a single hand resting at a single home key position. This corrects the prior art problems of requiring many keys in the very small space available on a portable pocket-sized pager instrument, such as thirty, for alphanumeric data input to pagers, where they are too close together for easy input and are not adaptable to touch typing techniques.
  • the keyboard is compatible with a comprehensive pager system which includes a wide range of data processing, printing, display, audio, recording, etc. capabilities now available in the computer arts, all controllable by the twelve key keyboard. This is achieved by providing a paging-data processing system responsive to keyboard input signals from two successive keystrokes in time sequence, thereby giving the capability for 144 combinations of coded signals from the twelve keys.
  • a twelve key keyboard layout is afforded that provides a comfortable and spacious arrangement for the fingers of one hand to type in a touch typing mode.
  • Those twelve keys are used in this invention to afford about 144 coded selections, thereby providing for entry of numerical and alphabetic characters and an additional range of about one hundred control codes that may be used for data processing in­structions, generally involving the use of the execute key XEQ.
  • the key columns are laid out on the keyboard 40 to conform with the shape of a human hand to thereby fit the natural finger position of the hand to the keys in operating position. This reduces fatigue, and prevents errors from unnatural reach positions or those that require an abnormal finger position.
  • a keyboard 40 having alphanumeric capacity and operable in the touch type mode with the fingers of one hand is made possible by this invention in the compact miniature pocket-sized housing 41, slightly larger than the size of a human hand.
  • Radio transmissions are handled by antenna 42, and may permit audio communications by way of speaker-microphone 43.
  • Provisions are made for visual readout on panel 44 and for printout or storage on tape 45 from an internal printer or recorder.
  • the internal data processing and communications system is of the modern computer-data processing type that affords internal storage and stored program subroutines that permit many different kinds of functions for providing such features as dictating mode of operation, calculations, data organization, and communication with like pager instruments.
  • the key diagram of Figure 2 illustrates the advance in the art made by this invention in communicating with alphanumeric character capabilities by means of manual keyboard input from only twelve keys.
  • the system thus is constructed to include special data handling features by operation of the keyboard keys to process entries in response to two successive mutually exclusive time sequential keystrokes from different ones of the keys.
  • the operation in the two keystroke per entry mode is as set forth in our US-A-4,547,860.
  • even fewer keyboard keys are required by operation of the decimal point key 46 in a mode that permits it to be an entry key. Since a decimal point only appears once within a numeric word, the second decimal point will serve as an entry key in a numeric calculating mode. It is thus possible to operate in a one stroke per entry mode for numeric data and to use the execute key XEQ to change the mode to a two stroke per entry mode for providing 144 selections including a full alphabet.
  • the keys in the row of keys 47 are designated with a keyboard chart to show entry of a set of 36 alphabet characters.
  • entry of the letter "A” for example. Because of location on the "4" key it serves as the first keystroke entry of two sequential keystrokes required for entry of an alphabetic character. The second keystroke is identified on the chart as the "7" key. This an "A” is entered by keystrokes 4-7. Similarly a “G” is entered by strokes 6-7, etc.
  • a telephone line voice grade communication system has been proposed in US-A-3,967,273, as a means of communicating with digitalized audio tones coded in alphanumeric format as obtained from a telephone instrument having only twelve keyboard keys operated in a two-stroke per character mode.
  • the received information may be decoded and stored as alphanumeric text for input to a conventional computer system.
  • the transmission channel 56 of Figure 3 operates independently from the two stroke per character coding of keyboard 40. Accordingly the interface data organizer 55 of the alphanumeric digital data processor 50 provides data that can be efficiently transmitted in digital format at high transmission speeds over a radio communication link.
  • the information transmitted in digital form is compatible with the alphanumeric information organized and stored in the register 52 from keyboard input so that when sent or received at high speed transmission rates greatly exceeding manual keyboard entry speeds it is readily processed in register 52.
  • the keyboard 40 may set up instructions for printout (58) or display at the viewing panel 44 of the data received and stored in register 52.
  • the system may serve only to provide a signal alarm when a message is received, so that the data may be recalled from the memory when desired by means of appropriate keyboard entered instructions.
  • the pager instrument may be comprehensive enough to have a voice recorder and dictation controls coupled to the transmission channel in a manner directed by control signals entered by the keyboard 40 to program the data processor or to select stored program subroutines therein.
  • the keyboard input signals coded in the two keystroke per entry format are processed in the keyboard interface data organizer 51 to communicate to the alphanumeric digital data processor 50 in internal machine language and are not used in the transmission channel.
  • the display register 57 of the type used in digital computers, processes the information called out from storage in register 52 in a format for sequentially printing out or viewing on the viewing panel 44 in the manner common in personal computers, all under control of the instructions provided by the keyboard, as provided also in personal computer operation.
  • This invention advances the art by providing a hand-held, keyboard controlled sending and receiving paging instrument having only twelve keys operable to produce decimal characters and alphabetic characters with a further set of over 100 instruction and control entries being available.
  • a keyboard operating in the two stroke per entry mode is directly coupled to actuate a digital data processing system and to enter alphanumeric information thereinto by the twelve key keyboard.
  • This data processing system then organizes data for transmission by a radio transmission link to like pager instruments in a two-way communication system, which sends alphanumeric information out at high transmission rates.
  • the transmissions are not limited in length, except by the capacity of the internal pager memory.
  • the system is flexible in its capacity to organize data compatible with various radio transmission system specifications. With the data processing system controlled by the 144 input functions from only twelve keys this system can be most comprehensive in designating or organizing the functions to be performed. Yet on a pocket-sized instrument, a keyboard simple to use in a touch typing mode is afforded that eliminates the large number of keys formerly used on data processing or paging devices having alphanumeric capabilities.
