Abstract

An identification module for one or more passive components in a system is used for storing information relating to the passive components. By storing component information relating to a passive component in a non-volatile memory module, such as a serial electrically erasable programmable read-only memory module, and incorporating the module into a sub-system having the passive component, the component information may be obtained at any time. This can reduce the time required to identify specifications of, and verify operation of, the passive components of a system. The probability of human error may also be reduced.

Claims

1. At sub-system comprising:

at least one passive component; and

an identification module for storing component information relating to said at least one passive component.

2. The sub-system of claim 1 wherein said component information comprises component identification information, component specifications, and component calibration data.

3. The sub-system of claim 1 further comprising a common interface for said at least one passive component and said identification module.

4. The sub-system of claim 3 wherein said interface comprises optical or electrical terminals for said at least one passive component and electrical terminals for said identification module.

5. The sub-system of claim 1 wherein said identification module comprises a non-volatile memory.

6. The sub-system of claim 5 further comprising:

a tester interconnected with said at least one passive component; and

a processor interconnected with said memory and with said tester.

7. The sub-system of claim 5 wherein said non-volatile memory comprises a read-only memory.

8. The sub-system of claim 7 wherein said identification further comprises a second memory, said second memory being a read-write memory.

9. The sub-system of claim 8 wherein said second memory stores historical performance information relating to said at least one passive component.

10. Apparatus for monitoring a passive component, comprising:

a non-volatile memory storing specifications for a passive component;

a tester for detecting signals at an input and output of said passive component; and

a. processor operatively associated with said non-volatile memory and said tester for monitoring proper performance of said passive component.

11. A method for facilitating monitoring of a passive component, comprising:

storing component information for said passive component in a non-volatile memory; and

installing said non-volatile memory in a sub-system incorporating said passive component.

12. The method of claim 11 further comprising configuring a common interface for said passive component and said non-volatile memory.

14. The method of claim 13 further comprising, based on said comparing, selectively generating a warning.

13. A method for monitoring a passive component, comprising:

retrieving specification information for said passive component from non-volatile memory installed in a sub-system incorporating said passive component;

sampling an input signal to and an output signal from said passive component;

determining performance characteristics for said passive component based on said sampling;

comparing said performance characteristics with said retrieved specification information.
