Methods and apparatus for automatic identification wristband

1. An apparatus comprising:

a flexible strap comprising

a plurality of holes,

a strap buckle configured to buckle to at least one of the plurality of holes, such that, when the strap buckle is buckled to the at least one hole, the strap forms a closed loop, and

a non-electrically-conductive material that electrically conductively separates a first electrically conductive portion of the strap, comprising a first one of the plurality of holes, from a second electrically conductive portion of the strap, comprising a second one of the plurality of holes; and

a tag enclosure comprising

a first buckle configured to buckle to the first hole,

a second buckle configured to buckle to the second hole, and

an electrically conductive material, such that, when the first buckle is buckled to the first hole of the first electrically conductive portion on a side of the non-electrically-conductive material and the second buckle is buckled to the second hole of the second electrically conductive portion on an opposite side of the non-electrically-conductive material, the electrically conductive material of the tag enclosure electrically conductively connects the first electrically conductive portion of the strap to the second electrically conductive portion of the strap across the non-electrically-conductive material of the flexible strap.

2. The apparatus of claim 1 , wherein the first buckle is configured to, after having been buckled to the first hole, be unbuckled from the first hole.

3. The apparatus of claim 2 , wherein the second buckle is configured to, after having been buckled to the second hole, be unbuckled from the second hole.

4. The apparatus of claim 1 , wherein each of the first buckle and the second buckle are configured to buckle to any one of the first hole and the second hole.

5. The apparatus of claim 1 , wherein the plurality of holes are identical.

6. The apparatus of claim 5 , wherein the strap buckle, the first buckle of the tag enclosure, and the second buckle of the tag enclosure are identical.

7. The apparatus of claim 6 , wherein each of the strap buckle, the first buckle of the tag enclosure, and the second buckle of the tag enclosure comprises:

a buckle portion; and

a folding portion comprising a target hole,

wherein the folding portion is configured to fold around the strap, such that one of the plurality of holes in the strap is positioned between the buckle portion and the folding portion, and

wherein the buckle portion is configured to be pressed through both the one hole in the strap, positioned between the buckle portion and the folding portion, and the target hole.

8. The apparatus of claim 1 , wherein, when the strap forms the closed loop, the first electrically conductive portion is electrically conductively connected to the second electrically conductive portion via buckling of the strap buckle to the at least one hole, such that, when the first buckle of the tag enclosure is buckled to the first hole of the first electrically conductive portion and the second buckle of the tag enclosure is buckled to the second hole of the second electrically conductive portion, the strap and the tag enclosure form a closed circuit loop.

9. The apparatus of claim 8 , wherein the strap buckle is electrically conductive and the at least one hole is formed in electrically conductive material of the strap, such that, buckling of the strap buckle to the at least one hole forms an electrically conductive contact.

10. The apparatus of claim 9 , wherein the strap buckle is comprised in the first electrically conductive portion of the strap, and the at least one hole is comprised in the second electrically conductive portion of the strap.

11. The apparatus of claim 8 , further comprising a circuit that is active when the strap and the tag enclosure form the closed circuit loop, and inactive when the strap and the tag enclosure do not form the closed circuit loop.

12. The apparatus of claim 11 , further comprising a battery, wherein the tag enclosure comprises a radio-frequency identification (RFID) tag, wherein the circuit, when active, supplies energy from the battery to the RFID tag, and wherein the circuit, when inactive, does not supply energy from the battery to the RFID tag.

13. The apparatus of claim 12 , wherein the RFID tag is configured to operate in a battery-assisted passive mode when supplied with energy from the battery, and operate in a pure passive mode when not supplied with energy from the battery.

14. The apparatus of claim 13 , wherein the RFID tag is configured to receive an instruction, and, in response to the instruction, operate in the pure passive mode even when the closed circuit loop is formed.

15. The apparatus of claim 12 , wherein the battery is a printed battery.

16. The apparatus of claim 11 , wherein the tag enclosure comprises a radio-frequency identification (RFID) tag, wherein the circuit, when active, enables an antenna of the RFID tag to transmit data, and wherein the circuit, when inactive, disables the antenna of the RFID tag from transmitting data.

17. The apparatus of claim 11 , further comprising a sensor, wherein the circuit, when active, enables the sensor to monitor an environmental characteristic, and wherein the circuit, when inactive, disables the sensor from monitoring the environmental characteristic.

18. The apparatus of claim 17 , wherein the environmental characteristic comprises a temperature.

19. The apparatus of claim 17 , wherein the environmental characteristic comprises a pulse of a person in contact with the sensor.

20. The apparatus of claim 17 , wherein the environmental characteristic comprises a glucose level of a person wearing the apparatus.
