Abstract

Methods, sensors, and systems that prevent or reduce data loss when more than one external sensor transceiver is used with a sensor. A sensor may receive a transceiver identification (ID) of an external transceiver conveyed from the external transceiver and determine whether the received transceiver ID is a new transceiver ID. If sensor determines the received transceiver ID to be a new transceiver ID, the sensor may store the received transceiver ID in a nonvolatile storage medium of the sensor and convey, using the sensor, measurement information stored in the nonvolatile storage medium to the external transceiver.

Claims

1. A method of using a first node in a system having two or more nodes, the method comprising:

receiving, using the first node, a unique identification code from a second node in the system, wherein the unique identification code identifies the second node;

determining, using the first node, that the second node has not previously communicated with the first node based on the received unique identification code;

if the second node is determined to have not previously communicated with the first node, storing, using the first node, the received unique identification code in a nonvolatile storage medium of the first node; and

if the second node is determined to have not previously communicated with the first node, conveying, using the first node, information stored in the nonvolatile storage medium of the first node to the second node.

2. The method of claim 1, wherein the first node is a sensor in a living animal, and the second node is a transceiver external to the living animal.

3. The method of claim 1, wherein the first node is a smartphone, and the second node is a transceiver.

4. The method of claim 3, wherein the transceiver is external to a living animal and in communication with a sensor in the living animal and the smartphone.

7. The method of claim 1, wherein determining that the second node has not previously communicated with the first node based on the received unique identification code comprises determining that the received unique identification code does not match any unique identification code previously stored to the nonvolatile storage medium of the first node.

8. The method of claim 1, wherein the first node conveys the information to the second node only if the second node is determined to have not previously communicated with the first node.

5. System comprising:

a first node configured to convey a first unique identification (ID);

a second node configured to convey a second unique ID;

a third node including circuitry, wherein the circuitry includes a non-volatile storage medium and is configured to;

receive the first unique ID conveyed from the first node;

store the received first unique ID in the nonvolatile storage medium;

receive the second unique ID conveyed from the second node;

determine that the received second unique ID is a new unique ID by comparing the received second unique ID to the stored first unique ID;

store the received second unique ID in the nonvolatile storage medium; and

convey information stored in the nonvolatile storage medium to the second node.

6. The system of claim 5, wherein the first unique ID identifies the first node, and the second unique ID identifies the second node.

9. A first node in a system having two or more nodes, the first node comprising:

an inductive element;

circuitry including a non-volatile storage medium, wherein the circuitry is configured to;

use the inductive element to receive a unique identification code from a second node in the system, wherein the unique identification code identifies the second node;

determine that the second node has not previously communicated with the first node based on the received unique identification code;

if the second node is determined to have not previously communicated with the first node, store the received unique identification code in the nonvolatile storage medium; and

if the second node is determined to have not previously communicated with the first node, convey, using the inductive element, information stored in the nonvolatile storage medium to the second node.

10. The first node of claim 9, wherein the circuitry is configured to determine that the second node has not previously communicated with the first node based on the received unique identification code by determining that the received unique identification code does not match any unique identification code previously stored to the nonvolatile storage medium.

11. The first node of claim 9, wherein the circuitry is configured to convey the information to the second node only if the second node is determined to be a new node that has not previously communicated with the first node.

12. A method of using a first node in a system having two or more nodes, the method comprising:

receiving, using the first node, a unique identification code from a second node in the system, wherein the unique identification code identifies the second node, the first node is a sensor in a living animal, and the second node is a transceiver external to the living animal;

determining, using the first node, that the second node has not previously communicated with the first node based on the received unique identification code, wherein determining that the second node has not previously communicated with the first node comprises determining that the received unique identification code does not match any unique identification code previously stored to a nonvolatile storage medium of the first node.

13. A method of using a first node in a system having two or more nodes, the method comprising:

receiving, using the first node, a unique identification code from a second node in the system, wherein the unique identification code identifies the second node, the first node is a smartphone, and the second node is a transceiver;

determining, using the first node, that the second node has not previously communicated with the first node based on the received unique identification code, wherein determining that the second node has not previously communicated with the first node comprises determining that the received unique identification code does not match any unique identification code previously stored to a nonvolatile storage medium of the first node.
