Abstract

A distributed computing environment for calibrating multiple components and reliably generating calibration data about each of the components. The calibration data from a plurality of calibration devices is stored in a database in a manner that avoids the problem of data collisions. The calibration devices include specific components or modules that allow each calibration device to independently generate calibration data, buffer calibration data, archive calibration data, transmit and receive data signals from a database, and receive data signals from a global network and display them for an operator. A method is disclosed which generated calibration data and subsequently detects and corrects calibration errors within a distributed network in a time frame that avoids the unnecessary disposal of improperly calibrated devices.

Claims

1. A method for managing data, the method comprising:

over a distribution network comprising a plurality of calibration devices, obtaining calibration data from each calibration device and temporarily archiving the calibration data locally at each calibration device, generation of the calibration data being achieved in connection with physical interactions between the calibration devices and respective associated components;

receiving, over the distributed network, the calibration data from one or more of the plurality of calibrating devices;

storing the calibration data received from the one or more calibrating devices in a database such that the calibration data is organized in a standard format that can be compared with other calibration data;

comparing calibration data from one calibration device with calibration data from another calibration device; and

enabling the calibration data to be accessed by one or more network devices of a global network.

2. The method of claim 1, further comprising transmitting a message to one of the calibrating devices.

3. The method of claim 1, wherein calibration data is received concurrently from two or more of the plurality of the calibrating devices.

4. The method of claim 1, wherein at least a portion of the method is performed at a point of manufacture of a component in connection with which some of the calibration data is obtained.
