  • Patent number: 6502005
    Abstract: An elapsed time clock is incorporated into a part call tag for requesting replenishment of components used by workstations of a manufacturing facility. One or more transmission readers spatially distributed around the manufacturing facility detect a part call signal transmitted from the part call tag. A reader output processing subsystem processes part call signals detected by at least one of the tag transmission readers to recover information contained in the part call signal. A management processor associates the recovered information with a respective workstation, and what component is to be replenished. The elapsed time clock is reset when the part call tag is operated to transmit a part call signal, and thereby serves as a call tag ‘stop watch’—informing workstation personnel of the length of time that has elapsed since the last part call transmission from that tag.
