Patent attributes
A digital display tape measuring device is disclosed having a display screen exteriorly for displaying the measured distance. A tape having electrical conductivity capabilities and an insulator disposed longitudinally along the tape dividing the tape into two electrical conductors, and having a tip thereof electrically connecting both of the electrical conductors together such that an electrical circuit is formed with resistance that varies as the tape is extracted from device. An ohmmeter electrically coupled across the electrical circuit for measuring the circuit resistance. A microprocessor having inputs thereof coupled to outputs of the ohmmeter and having outputs coupled to said display screen. The microprocessor computes measurements made by as a function of the resistance measured by the ohmmeter.
