Abstract

A powered system includes a parent module including a first battery storing a charge and a child module including a second battery storing a charge and a controller. When the parent module and the child module are in electrical communication, the controller is configured to receive power from the parent module. When the charge in the parent module is depleted, the controller is configured to backfeed power from the child module to the parent module.

Claims

1. A powered system, comprising:

a parent module including a first battery storing a charge; and

a child module including a second battery storing a charge and a controller,

wherein when the parent module and the child module are in electrical communication, the controller is configured to receive power from the parent module;

wherein, when the charge in the parent module is depleted, the controller is configured to backfeed power from the child module to the parent module;

wherein the child module further includes one or more male connector pins configured to mate with a female connector, and wherein the controller is configured to de-energize the one or more male connector pins when the controller detects that the child module is not connected to the female connector;

wherein the child module further includes a display, wherein the child module is configured to receive vital sign data, and wherein the child module is configured to display the vital sign data; and

wherein the display includes an expected battery life display, the expected battery life display indicating the expected battery life including both the first battery and the second battery.

2. The powered system of claim 1, wherein the first battery comprises a nine-cell battery, and wherein the second battery comprises a two-cell battery.

3. The powered system of claim 1, wherein the powered system, when the child module is connected to a mains power source, is powered exclusively off the mains power source, and when the child module is unconnected to the mains power source, the powered system initially is powered exclusively off the first battery.

4. The powered system of claim 1, wherein the powered system, when the child module is connected to a mains power source, is powered exclusively off the mains power source, and when the child module is unconnected to the mains power source, the powered system initially is powered exclusively off the first battery.

5. A medical device, comprising:

a parent module including a first battery;

a child module including a second battery and a controller, the child module configured to receive vital signs data, wherein the parent module and the child module are in electrical communication, the controller is configured to receive power from the parent module; and

wherein when a charge in the first battery is depleted, the controller is configured to backfeed power from the child module to the parent module;

wherein the child module further includes one or more male connector pins configured to mate with a female connector, and wherein the controller is configured to de-energize the one or more male connector pins when the controller detects that the child module is not connected to the female connector;

wherein the first battery comprises a nine-cell battery, and wherein the second battery comprises a two-cell battery;

wherein the child module further includes a display, and wherein the child module is configured to display the vital sign data on the display; and

wherein the display includes an expected battery life display, the expected battery life display indicating the expected battery life including both the first battery and the second battery.

6. The medical device of claim 5, wherein the medical device, when the child module is connected to a mains power source, is exclusively powered off the mains power source;

and when the child module is unconnected to the mains power source, the medical device initially is powered exclusively off the first battery.

7. The medical device of claim 5, wherein the medical device, when the child module is connected to a mains power source, is powered exclusively off the mains power source, and when the child module is unconnected to the mains power source, the medical device initially is powered exclusively off the first battery.

8. A method of powering a medical device, the method comprising:

providing a parent module including a first battery storing a charge; and

providing a child module including a second battery storing a charge and a controller,

when the parent module and the child module are in electrical communication, powering the controller from the parent module;

when the charge in the parent module is depleted, backfeeding power from the child module to the parent module;

receiving vital sign data;

displaying the vital sign data; and

displaying an expected battery life display, the expected battery life display indicating the expected battery life including both the first battery and the second battery.

9. The method of claim 8, further comprising:

when the child module is connected to a mains power source, powering the medical device exclusively off the mains power source; and

when the child module is unconnected to the mains power source, initially powering the medical device exclusively off the first battery.
