Abstract

Methods and devices for power cycling an electronic device are provided. Also provided are systems and kits.

Claims

1. An electronic device, comprising

a data processor,

a reset circuit;

a power source; and

a memory comprising instruction that;

provides a reset signal to the data processor to initiate a first power reset cycle;

supplies power to the data processor while enabling the reset circuit to initialize the electronic device to a first state; and

disables the reset circuit while maintaining power to the data processor to operate the electronic device and to complete the first power reset cycle;

enables the reset circuit while maintaining power to the data processor to initiate a second power reset cycle;

removes power to the data processor while the reset circuit is enabled to perform the second power reset cycle; and

disables the reset circuit to complete the second power reset cycle.

2. The electronic device of claim 1, wherein the enabling the reset circuit comprises conductively grounding the reset circuit.

3. The electronic device of claim 2, wherein the conductively grounding the reset circuit comprises positioning one pole of a battery across two reset contact points.

4. The electronic device of claim 3, wherein the supplying power to the data processor comprises positioning the battery between ground and a power circuit of the device.

5. The electronic device of claim 4, wherein the disabling the reset circuit includes removing the battery from the two reset contact points.

6. The electronic device of claim 1, wherein the power source comprises a battery receptacle terminal configured to receive a battery pack including at least one cathode terminal and at least one anode terminal, and at least one reset pad electrically coupled to an input of the reset circuit.

7. The electronic device of claim 6, wherein the battery pack comprises a housing and at least one battery retained in the housing and positioned between at least one battery between the at least one cathode terminal and the at least one anode terminal, the battery configured to provide power to as the supply voltage of the electronic device, wherein the insertion of the battery pack into the battery receptacle triggers the reset circuit to initiate the power reset cycle of the electronic device, to initialize the electronic device to a known state, and to complete the initiated power reset cycle.

8. The electronic device of claim 1, wherein the data processor includes a microprocessor.

9. The electronic device of claim 7, wherein a separation distance between the at least one cathode terminal and the at least one anode terminal is less than a thickness of the at least one battery.

10. The electronic device of claim 6, wherein the at least one battery is a replaceable battery.

11. The electronic device of claim 6, wherein the battery pack is configured to engage with the battery receptacle terminal in a sliding or snap-fit manner.

12. The electronic device of claim 1, wherein the reset circuit that provides a reset signal to the data processor via a reset line, the reset circuit including a reset switch comprising at least one reset pad provided on a printed circuit board, the reset circuit configured to initiate a power reset cycle of the electronic device.

13. The electronic device of claim 12, wherein the at least one reset pad includes a first reset pad electrically coupled to device ground and a second reset pad electrically coupled to an input of the reset circuit.

14. The electronic device of claim 12, wherein a height of the at least one reset pad is greater than a top surface of the at least one cathode terminal.

15. The electronic device of claim 12, wherein the height of the at least one reset pad is in a range of 0.01 mm to 1.0 mm.

16. The electronic device of claim 12, wherein the electronic device is an analyte meter.

17. The electronic device of claim 12, wherein the analyte is glucose.
