Abstract

A physiological test credit method determines if test credits are available to the monitor and checks if a Wi-Fi connection is available. If test credits are less than a test credit threshold, the monitor connects to a test credit server, processes server commands so as to download test credits and disconnects from the server. In various embodiments, the monitor is challenged to break a server code, the server is challenged to break a monitor code. The server validates monitor serial codes, and saves monitor configuration parameters.

Claims (35)

1. A physiological monitoring system configured to perform parameter spot-checks on a per test credit basis, the system comprising:

a remote server comprising a processor and a memory, wherein the memory includes computer-executable instructions;

wherein the processor of the remote server is configured to execute the instructions to establish secure communication with a physiological monitor by:

initiating a two-way challenge by sending a first code for the physiological monitor to break in response to the physiological monitor establishing a connection with the remote server, wherein the physiological monitor is configured to be coupled to a sensor, the physiological monitor comprising one or more signal processors, the sensor configured to be placed at a measurement location of a user, the sensor comprising a memory configured to store one or more test credits;

establishing a secure communication channel between the physiological monitor and the processor of the remote server in response to the two-way challenge being met by the remote server and the physiological monitor;

sending test credits from the remote server to the physiological monitor; and

receiving an acknowledgement for receipt of the test credits, wherein upon the remote server receiving the acknowledgement, the remote server is further configured to:

deduct the test credit from a user account at the remote server;

increment a test credit downloading index count at the remote server; and

perform an update to the one or more test credits saved on the memory of the sensor via communication with the physiological monitor through the secure communication channel.

2. The physiological monitoring system of claim 1 , wherein the remote server is further configured to drop the connection with the physiological monitor in response to the physiological monitor's inability to break the first code.

3. The physiological monitoring system of claim 1 , wherein the remote server is further configured to request the physiological monitor to send a second code for the remote server to break in response to the physiological monitor breaking the first code.

4. The physiological monitoring system of claim 3 , the monitor is configured to drop the connection in response to the remote server's inability to break the second code.

5. The physiological monitoring system of claim 1 , wherein the remote server is configured to determine whether the update is manual or automatic.

6. The physiological monitoring system of claim 1 , wherein the remote server is configured to perform the update by providing a credit file for the physiological monitor to download.

7. The physiological monitoring system of claim 1 , wherein the remote server is further configured to validate a monitor or user account by requesting monitor and sensor data prior to performing the update.

8. The physiological monitoring system of claim 1 , wherein the remote server acts in a master role and the physiological monitor acts in a slave role once the connection is established.

9. The physiological monitoring system of claim 1 , wherein the first code comprises secret hashing.

10. The physiological monitoring system of claim 1 , wherein the physiological monitor is configured to establish the connection with the remote server in response to the one or more test credits falling below a predefined update threshold.

11. A method to establish a connection to update one or more test credits used to perform parameter spot-checks on a per test credit basis, the method comprising:

initiating a two-way challenge by a remote server sending a sending a first code for a physiological monitor to break in response to the physiological monitor establishing a connection with the remote server, wherein the physiological monitor is configured to be coupled to a sensor and comprising one or more signal processors, the sensor configured to be placed at a measurement location of a user, the sensor comprising a memory configured to store one or more test credits;

establishing a secure communication channel between the physiological monitor and a processor of the remote server in response to the two-way challenge being met by the remote server and the physiological monitor;

sending test credits from the remote server to the physiological monitor;

receiving an acknowledgment for receipt of the test credits;

deducting the test credit from a user account at the remote server;

incrementing a test credit downloading index count at the remote server; and

performing an update to the one or more test credits saved on the memory of the sensor via communication with the physiological monitor through the secure communication channel.

12. The method of claim 11 , wherein the remote server drops the connection with the physiological monitor in response to the physiological monitor's inability to break the first code.

13. The method of claim 11 , wherein the remote server requests the physiological monitor to send a second code for the remote server to break in response to the physiological monitor breaking the first code.

14. The method of claim 13 , wherein the physiological monitor drops the connection in response to the remote server's inability to break the second code.

15. The method of claim 11 , wherein the remote server determines whether the update is manual or automatic.

16. The method of claim 11 , wherein the remote server performs the update by providing a credit file for the physiological monitor to download.

17. The method of claim 11 , wherein the remote server validates a monitor or user account by requesting monitor and sensor data prior to performing the update.

18. The method of claim 11 , wherein the first code includes secret hashing.

19. The method of claim 11 , wherein the physiological monitor establishes the connection with the remote server in response to the one or more test credits falling below a predefined update threshold.
