Abstract

Systems and methods for managing current flow in a power circuit used to dynamically share power are disclosed. A Zener diode may automatically adjust current flow in the power circuit. If the power circuit has not received sufficient current for dynamic power sharing, the Zener diode may draw additional current from a power source. An electrical current in the power circuit may be divided into a plurality of current loads. Each of the plurality of current loads may be directed through a different path in the power circuit.

Claims (36)

1 . A method comprising:

sending, by a power circuit associated with a device and to a first component of the device, a first current load, wherein the first current load is sufficient to power the first component of the device without using a battery;

receiving an indication that a second component of the device is to be activated; and

sending, based on the indication that the second component of the device is to be activated, a combination of the first current load and a second current load, wherein the combination is sufficient to power the second component of the device without using a battery.

2 . The method of claim 1 , wherein the first current load comprises current sufficient to power the first component of the device when the combination is sent to the second component of the device to power the second component of the device.

3 . The method of claim 1 , wherein the combination comprises current sufficient to power the second component of the device when the first current load is sent to the first component of the device to power the first component of the device.

4 . The method of claim 1 , wherein sending the combination comprises directing the second current load through a bypass path in the power circuit.

5 . The method of claim 4 , wherein sending the first current load comprises directing the first current load through a second path in the power circuit, the second path connected in a parallel path to the bypass path.

6 . The method of claim 1 , wherein the first component of the device comprises a doorbell camera, the second component of the device comprises a doorbell chime, and the power circuit is electrically coupled to the doorbell chime and the doorbell camera.

7 . A device comprising:

a first component;

a second component; and

a power circuit electrically coupled to the first component and the second component, the power circuit in electrical communication with a power source, wherein the device is configured to cause the power circuit to:

send, to the first component, a first current load, wherein the first current load is sufficient to power the first component without using a battery;

receive an indication that the second component is to be activated; and

send, based on the indication that the second component is to be activated, a combination of the first current load and a second current load, wherein the combination is sufficient to power the second component without using a battery.

8 . The device of claim 7 , wherein the first current load comprises current sufficient to power the first component of the device when the combination is sent to the second component of the device to power the second component of the device.

9 . The device of claim 7 , wherein the combination comprises current sufficient to power the second component of the device when the first current load is sent to the first component of the device to power the first component of the device.

10 . The device of claim 7 , wherein the device is configured to send the combination by directing the second current load through a bypass path in the power circuit.

11 . The device of claim 10 , wherein the device is configured to send the first current load by directing the first current load through a second path in the power circuit, the second path connected in a parallel path to the bypass path.

12 . The device of claim 7 , wherein the first component comprises a doorbell camera and the second component comprises a doorbell chime.

13 . The device of claim 7 , wherein the power source is an AC power source.

14 . A system comprising:

a first component;

a second component;

a power source; and

a power circuit electrically coupled to the first component and the second component, the power circuit in electrical communication with the power source, wherein the power circuit is configured to:

send, to the first component, a first current load, wherein the first current load is sufficient to power the first component without using a battery;

receive an indication that the second component is to be activated; and

send, based on the indication that the second component is to be activated, a combination of the first current load and a second current load, wherein the combination is sufficient to power the second component without using a battery.

15 . The system of claim 14 , wherein the first current load comprises current sufficient to power the first component when the combination is sent to the second component to power the second component.

16 . The system of claim 14 , wherein the combination comprises current sufficient to power the second component when the first current load is sent to the first component to power the first component.

17 . The system of claim 14 , wherein the power circuit is configured to send the combination by directing the second current load through a bypass path in the power circuit.

18 . The system of claim 17 , wherein the power circuit is configured to send the first current load by directing the first current load through a second path in the power circuit, the second path connected in a parallel path to the bypass path.

19 . The system of claim 14 , wherein the first component comprises a doorbell camera and the second component comprises a doorbell chime.

20 . The system of claim 14 , wherein the power source is an AC power source.
