Abstract

Techniques for alerting for instruments that transfer physical samples are disclosed. An alarm module, placed within a communication pathway of a first chemical processor and a second chemical processor, includes a timer configured to count time elapsed since receiving, from the first chemical processor, a transfer-ready signal indicating that 1) the first chemical processor received a receive-ready signal from the second chemical processor; ii) the first chemical processor has completed processing a chemical analyte; and iii) the first chemical processor is ready to physically transfer the chemical analyte to the second chemical processor. Upon receiving the transfer-ready signal from the first chemical processor, the timer is restarted. An alarm triggers when the elapsed time counted by the timer exceeds a specified threshold. The alarm is audible or visual. Upon the triggering of an alarm, an alert notification (e.g., an email, a text message, etc.) is transmitted.

Claims

1. An instrumentation alerting system for monitoring a readiness of a second chemical processor to receive a physical transfer of a chemical analyte from a first chemical processor, the instrumentation alerting system comprising:

a timer configured to count time elapsed since receiving a transfer-ready signal;

an alarm configured to trigger when the elapsed time counted by the timer exceeds a specified threshold, whereby the alarm trigger indicates that at least one of the first chemical processor and the second chemical processor is not operating properly; and

a circuit, when connected to a communication link between the first chemical processor and the second chemical processor, configured to;

monitor for the transfer-ready signal from the first chemical processor, wherein the transfer-ready signal indicates that;

i) the first chemical processor received a receive-ready signal from the second chemical processor over the communication link;

ii) the first chemical processor has completed processing the chemical analyte; and

iii) the first chemical processor is ready to physically transfer the chemical analyte to the second chemical processor; and

restart the timer based on receipt of the transfer-ready signal from the first chemical processor.

2. The instrumentation alerting system of claim 1, wherein the alarm is configured to cause a fault entry to be logged into a database when the elapsed time counted by the timer exceeds a specified threshold.

3. The instrumentation alerting system of claim 1, wherein the alarm is configured to cause an alert to execute when the elapsed time counted by the timer exceeds a specified threshold.

4. The instrumentation alerting system of claim 3, wherein the alert is at least one of:

an audible alarm; and

a visual alarm.

5. The instrumentation alerting system of claim 1, wherein the alarm is configured to cause a notification to execute when the elapsed time counted by the timer exceeds a specified threshold.

6. The instrumentation alerting system of claim 5, wherein the notification is at least one of:

transmission of an email to a specified email address;

transmission of a text message to an address of a device capable of receiving text messages, and

transmission of a telephonic call to a specified telephone number.

7. The instrumentation alerting system of claim 1, wherein the physical sample is a vial of liquid.

8. The instrumentation alerting system of claim 1, wherein the physical sample is a mixture of a gas with a carrier gas.

9. The instrumentation alerting system of claim 2, wherein the specified time period is between 5 and 45 minutes.

10. The instrumentation alerting system of claim 3, wherein the specified time period is thirty minutes.

11. The instrumentation alerting system of claim 1, wherein the transfer-ready signal further indicates that:

i) a third chemical processor has completed processing the chemical analyte; and

ii) the third chemical processor has physically transferred the chemical analyte to the first chemical processor.

12. The instrumentation alerting system of claim 1,

wherein the first chemical processor and the second chemical processor are configured to perform a continuous, sequential process whereby the first chemical processor processes chemical analytes and transfers the processed chemical analytes to the second chemical processor;

and

wherein the second chemical processor does not send the receive-ready signal to the first chemical processor until the second chemical processor has completed processing one of the chemical analytes most recently received from the first chemical processor.

13. A method of monitoring a readiness of a second chemical processor to receive a chemical analyte from a first chemical processor, the method comprising:

starting a timer that counts time elapsed since receiving a transfer-ready signal;

monitoring for the transfer-ready signal from the first chemical processor, the transfer-ready signal indicating that;

i) the first chemical processor received a receive-ready signal from the second chemical processor;

ii) the first chemical processor has completed processing the chemical analyte, and

iii) the first chemical processor is ready to transfer the chemical analyte to the second chemical processor;

restarting the timer after receiving the transfer-ready signal;

triggering an alarm if the elapsed time counted by the timer exceeds a specified threshold, whereby the alarm trigger indicates that at least one of the first chemical processor and the second chemical processor is not operating properly.

14. The method of claim 13, further comprising:

causing a fault entry to be logged into a database when the elapsed time counted by the timer exceeds a specified threshold.

15. The method of claim 13, further comprising:

causing an alert to execute when the elapsed time counted by the timer exceeds a specified threshold.

16. The method of claim 15, wherein the alert is at least one of:

an audible alarm; and

a visual alarm.

17. The method of claim 13, further comprising:

causing a notification to execute when the elapsed time counted by the timer exceeds a specified threshold.

18. The method of claim 13, wherein the notification is at least one of:

transmission of an email to a specified email address;

transmission of a text message to an address of a device capable of receiving text messages; and

transmission of a telephonic call to a specified telephone number.

19. The method of claim 13, wherein the physical sample is a vial of liquid.

20. The method of claim 13, wherein the physical sample is a mixture of a gas with a carrier gas.

21. The method of claim 14, wherein the specified time period is thirty minutes.

22. The method of claim 15, wherein the specified time period is thirty minutes.

23. The method of claim 13, wherein the transfer-ready signal further indicates:

i) that a third chemical processor has completed processing the chemical analyte; and

ii) that the third chemical processor has physically transferred the chemical analyte to the first chemical processor.

24. The method of claim 13,

wherein the first chemical processor and the second chemical processor perform a continuous, sequential process whereby the first chemical processor processes a chemical analytes and transfers the processed chemical analytes to the second chemical processor;

and

wherein the second chemical processor does not send the receive-ready signal to the first chemical processor until the second chemical processor has completed processing one of the chemical analytes most recently received from the first chemical processor.

25. The method of claim 22, wherein the receive-ready signal indicates:

1) the second chemical processor has completed processing of the previously received chemical analyte; and

2) the second chemical processor has physically transferred the previously received chemical analyte to another device.

26. A method of monitoring a readiness of a third chemical processor to receive a chemical analyte from a second chemical processor, the method comprising:

processing a chemical analyte by a first chemical processor;

transferring, from the first chemical processor to the second chemical processor, the processed chemical analyte;
