  • Patent number: 3956740
    Abstract: An improved portable data entry machine is disclosed, wherein data may be keyed, viewed for accuracy, recorded on magnetic tape, recalled from magnetic tape, and telephonically transmitted for data processing. Improvements include a search feature to locate previously recorded data, an automatically controlled power switching unit to prolong the times that batteries may be used prior to recharging, microcomputer controlled circuitry to prevent attempted data entry under low-battery conditions, an electronic shutdown to prevent cell reversal, a voltage reference technique to minimize the power drain from the batteries, a unique mechanism and circuitry to preclude the inadvertent destruction of data, a low cost modem for communicating entered data to a remote location, an automatic interlock for the tape compartment, a highly effective display technique, a novel high voltage power supply, and an out-of-sequence detector.
