Abstract

Probe configuration is achieved in a measurement system in which probes are given possible configuration data depending upon conditions in an area relevant to the area of the probe. The possible probe configurations include global boundaries, such as time, and each probe then, based upon the possible configurations, selects a configuration. In one embodiment, the probe may interact with a central processor to further define the probe configuration. In one embodiment, probes may communicate with other probes, both to help define their operating environment and to optionally provide configuration data to another probe.

Claims

1. A probe for use in a measurement system;

said probe comprising;

memory for storing data pertaining to possible configurations for said probe;

a processor for selecting one of said possible probe configurations; and

;

a location determination device; and

wherein said possible probe configurations comprise;

location parameters for use by said processor to select a configuration from said possible configurations at least partially based on a determined location of said probe as suggested by a measurement system controller.

2. The probe of claim 1 wherein said processor is further operable to change said probe configuration from time to time depending upon a determined location of said probe.

3. The probe of claim 1 wherein said processor selection of probe configuration is dependant upon factors unique to said probe.

4. The probe of claim 3 wherein said unique factors include one or more of:

number of other probes in a defined area;

configurations of probes in a defined area;

a probability table built into said probe for each possible selection;

number of measurements made of a certain type by said probe;

participation percentage;

measurement values;

connectivity status; and

time.

5. The probe of claim 1 further comprising:

a communication device for communicating parameters pertaining to said probe to a data gathering point.

6. The probe of claim 5 wherein said possible probe configurations are communicated to said probe from said data gathering point.

7. The probe of claim 6 wherein said possible configurations are dependant upon said probe parameters communicated from said probe.

8. The probe of claim 1 wherein said possible probe configurations are communicated to said probe from a data gathering point.

9. The probe of claim 1 wherein said possible probe configuration data is at least one runnable software module.

10. A probe for use in a measurement system;

said probe comprising;

memory for storing data pertaining possible configurations for said probe;

a processor for selecting one of said possible configurations, wherein said possible probe configurations are communicated to said probe, at least in part, from another probe.

11. A method comprising:

in a measurement system, providing spaced-apart probes;

receiving configuration data at said probes, wherein said configuration data for each probe is a list of possible configurations for said probe; and

selecting, under control of each said probe, from said list of possible configurations, a configuration for use by said probe,

wherein said configuration data is communicated to said probes at least in part from another of said probes.

12. The method of claim 11 further comprising:

communicating measurements in accordance with said configuration data.

13. The method of claim 12 wherein said measurements are communicated to said measurement system.

14. The method of claim 11 further comprising:

communicating metadata to said measurement system from said probes.

15. The method of claim 11 wherein said configuration data is communicated to said probes at least in part from said measurement system.

16. The method of claim 11 wherein said processor is further operable to change said probe configuration from time to time depending upon a determined location of said probe.

17. The method of claim 11 wherein said selection of probe configuration is dependant upon factors unique to said probe.

18. The method of claim 17 wherein said unique factors include one or more of:

numbers of other probes in a defined area;

configurations of probes in a defined area;

a probability table built into said probe for each possible selection;

number of measurements made of a certain type by said probe;

participation percentage;

measurement values;

connectivity status; and

time.
