Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
121 words
An electronic component-identification system for use in identifying a plurality of components, said system comprising a plurality of differently coded passive component tags adapted to be respectively secured to said plurality of components, a master tag including a memory, a transceiver for receiving a coded interrogation signal, means for storing the different codes from said plurality of component tags in said memory of said master tag, said master tag further comprising logic means for comparing the codes stored in said memory with the coded interrogation signal received at said master tag from said transceiver and for producing a component-identification signal for each matching code comparison, and means for applying said component-identification signal to said transceiver for transmission to a remote station.
Claim 2
Dependent Claim
121 words
An electronic component-identification system for use in identifying a plurality of components, said system comprising a plurality of differently coded passive component tags adapted to be respectively secured to said plurality of components, a master tag including a memory, a transceiver for receiving a coded interrogation signal, means for storing the different codes from said plurality of component tags in said memory of said master tag, said master tag further comprising logic means for comparing the codes stored in said memory with the coded interrogation signal received at said master tag from said transceiver and for producing a component-identification signal for each matching code comparison, and means for applying said component-identification signal to said transceiver for transmission to a remote station.
Claim 3
Dependent Claim
52 words
The system of claim 1, in which each of said component tags including a surface and a plurality of electrical conducting paths on said surface, said paths being differently and selectively altered in each of said component tags, thereby to establish a different multi-digit binary code on each of said component tags.
Claim 4
Dependent Claim
37 words
The system of claim 1, in which said memory includes a plurality of memory stages, said master tag further comprising means for selectively applying the codes from said component tags into corresponding ones of said memory stages.
Claim 5
Dependent Claim
55 words
The system of claim 3, in which said comparing means comprises a plurality of comparators for respectively comparing the component tag codes stored in a corresponding plurality of memory stages with a received tag address code, and means for producing a match signal whenever one of the stored codes corresponds to the received address code.
Claim 6
Dependent Claim
44 words
The system of claim 1, in which said master tag includes a normally inoperative oscillator, and comprises means responsive to the production of said component-identification signal for actuating said oscillator, thereby to cause said master tag to transmit a signal to a remote unit.
Claim 7
Dependent Claim
37 words
The system of claim 5, in which said memory includes a plurality of memory stages, said master tag further comprising means for selectively applying the codes from said component tags into corresponding ones of said memory stages.
Claim 8
Dependent Claim
55 words
The system of claim 6, in which said comparing means comprises a plurality of comparators for respectively comparing the component tag codes stored in a corresponding plurality of memory stages with a received tag address code, and means for producing a match signal whenever one of the stored codes corresponds to the received address code.
