Abstract

The application is directed to methods, systems, procedures, networks and storage apparatus used to conduct conversions of data using remote conversion servers. In one embodiment of the present invention, recent query results may be stored and then used to solve subsequent conversions rather than querying a remote conversion server when the same conversion was previously completed. A counter may be referenced to determine if too much time has passed since the original query was stored in the buffer and, if too much time has passed, the buffer may be cleared and the remote conversion server may be queried to convert the pending data. The resulting conversion may be stored for subsequent use.

Claims

1. A system for querying a remote server over a network, the system comprising:

a processor wherein the processor is adapted to;

detect generation of input data containing measured parameters of a substance, wherein the measured parameters are rheological measurements of a petroleum product,

search a network-addressable storage memory device to determine if conversion results corresponding to the measured parameters are stored therein from a prior conversion procedure, wherein the conversion results include volumetric conversions, and

if the conversion results are stored in the storage memory device, provide the stored conversion results from the prior conversion procedure from the storage memory device,

if the conversion results are not stored in the storage memory device,

transmit a query with the measured parameters to a service at the remote server over the network,

receive computed conversion results in response thereto,

provide the computed conversion results from the remote server, and

store the computed conversion results in the storage memory device, wherein the stored computed conversion results are accessible for a future conversion procedure from the storage memory device.

2. The system of claim 1 wherein the processor is further adapted to perform a security verification on a user of the system prior to sending the query to the remote server.

3. The system of claim 1 wherein the rheological measurements of the petroleum product have been sensed by a remote sensor interfacing with the product.

4. The system of claim 2 wherein the security verification includes verifying that the user is authorized to convert the requested types of data.

5. The system of claim 1 wherein the processor is further adapted to perform a security verification of the remote server to verify that the server is authorized to complete a requested conversion.

6. The system of claim 1 wherein the conversion results are conversions to industry standard parameters.

7. The system of claim 1 wherein the conversion results were derived from an American Petroleum Institute, API, conversion server.

8. The system of claim 1 wherein the conversion results were derived from an American Gas Association, AGA, conversion server.

15. The system of claim 1 wherein the conversion results were derived from an American Petroleum Institute, API, conversion server.

16. The system of claim 1 wherein the conversion results were derived from an American Gas Association, AGA, conversion server.

19. The system of claim 1, wherein the storage memory device is a local memory.

20. The system of claim 19, wherein the local memory stores only the results of preceding conversion procedure.

21. The system of claim 1, wherein the storage memory device is a buffer device.

22. The system of claim 21, wherein the buffer device is a local device.

23. The system of claim 21, wherein the buffer device is a remote device accessible via the network.

24. The system of claim 21, wherein the buffer device stores a plurality of conversion results.

25. The system of claim 21, wherein the processor is further adapted to determine whether the stored conversion results have been stored in the buffer device for longer than a preselected time period,

if the stored conversion results have not been stored in the buffer device longer than the preselected time period, provide the stored conversion results in the response to the input data,

otherwise, erase the stored conversion results and transmit the query.

9. A programmable storage memory device storing instructions for a processor, the processor having communication inputs and communication outputs, the instructions comprising:

instructing the processor to recognize the presence of input data containing measured parameters of a substance, wherein the measured parameters are theological measurements of a petroleum product;

instructing the processor to search a network-addressable computer storage memory device to determine if conversion results for the measured parameters are stored in the storage memory device from a prior conversion procedure, wherein the conversion results include volumetric conversions; and

if the conversion results are stored in the storage memory device, instructing the processor to output the stored conversion results in response to the input data from the prior conversion procedure from the storage memory device,

otherwise, instructing the processor to query a conversion service in response to the input data, to receive a query response including computed conversion results, and to output the computed conversion results in response to the input data from the remote server, wherein the computed conversion results are stored in the storage memory device and are accessible for a future conversion procedure from the storage memory device.

10. The device of claim 9 further comprising instructions to perform a security verification on a user of the processor prior to sending the query.

otherwise, erase the stored conversion results and transmit the query.

17. A quantity conversion method, comprising:

responsive to a request to perform a standard condition conversion calculation, the request including rheological conditions of a petroleum product, comparing the rheological conditions against stored conditions of prior calculations maintained in a network-addressable storage memory device,
