Power supply with vehicle adapter and battery

An apparatus for adapting power from an outlet of a vehicle, the apparatus comprising:

• a control circuit for controlling the supply of power to an external electronics module mountable to a user for controlling an implanted device of the user, the control circuit electrically coupled to a switching circuit for controlling an electrical connection between an external power source, a battery, and an external electronics module, the control circuit further electrically coupled to a sensor for sensing at least one from the group consisting of a voltage and a current received from the external power source, the control circuit being configured to control the switching circuit to:
• electrically disconnect the external electronics module from the external power source and electrically connect the external electronics module to the battery in response to a sensed fluctuation of the sensed at least one from the group consisting of voltage and current;
• electrically connect the external electronics module to the external power source and electrically disconnect the external electronics module from the battery when the fluctuation is not sensed;
• and
• the apparatus being electrically coupled between the external power source and an external electronics module.

A system for controlling the supply of power to an implanted device, the system comprising:

• an apparatus including:
• a control circuit for controlling the supply of power to an external electronics module mountable to a user for controlling an implanted device of the user, the control circuit electrically coupled to a switching circuit for controlling an electrical connection between an external power source, a battery, and an external electronics module, the control circuit further electrically coupled to a sensor for sensing at least one from the group consisting of a voltage and a current received from the external power source, the control circuit being configured to control the switching circuit to:
• electrically disconnect the external electronics module from the external power source and electrically connect the external electronics module to the battery in response to a sensed fluctuation of at least one from the group consisting of voltage and current;

• an external electronics module controller for determining whether an amount of at least one from the group consisting of current and voltage received from the module is sufficient to power the implanted device;
• a second battery;
• a switch for switching between providing power from the apparatus to the implanted device and providing power from the second battery to the implanted device, in response to the determination of the external electronics module controller;
• and
• an alert module for notifying the user when power is provided from the second battery.

A method of controlling the supply of power to an external module mountable to a user of an implanted device, the external module providing power to the implanted device, the method comprising:

• at a control circuit, detecting a fluctuation in the level of power provided from an external power supply;
• in response to the detection, the control circuit controlling a switching circuit to electrically disconnect the external module from the external power source and electrically connect the external module to a battery coupled to the switching circuit in response to a detected fluctuation;
• and
• when no fluctuation is detected, the external module is electrically connected to the external power source.

A method of controlling issuance of alert indicating disconnection of an external power source from an implanted medical device, the method comprising:

• detecting a disruption of power being provided from the external power source;
• and
• controlling a switching circuit to electrically disconnect the implanted medical device from the implanted device and electrically connect a backup power source to the implanted medical device, the backup power source has an amount of charge sufficient to power the implanted device for less than between five seconds, and
• in the event of a disruption of power longer than the amount of charge to power the implanted device, the disruption of power results in issuance of the alert, and in the event of a disruption of power shorter than the five seconds, the backup power source prevents the alert from issuing.
