Abstract

A wake from OFF state system is described that enhances power adapters and battery chargers that have been shut completely off in efforts to conserve energy. Wake from OFF state devices may be used to automate the otherwise tedious process of turning on a power switch. A wake from OFF state device is distinguished from a wake from sleep state device which continues to consume some amount of power to operate in a standby mode. A wake from OFF state power adapter can be turned fully off and left off indefinitely. There are no active standby circuits, no power consumption, no active logic, no emissions, no heat, when the device is in this OFF state. Wake from OFF state is useful for a variety of devices including (but not limited to) smartphones, portable computers, power tools, electric vehicles, and rechargeable batteries.

Claims

1. ) A wake from OFF state power adapter system comprising:

a first connection device;

a wake from OFF state controller device;

a power processing device;

a power switching device;

a second connection device;

wherein when the power switching device is off, no power is consumed by the power adapter system;

wherein the wake from OFF state controller device receives power from an external device attached to the first connection device to initiate waking the power adapter system from an off state,

wherein the wake from OFF state controller device uses the received power to turn on the power switching device;

wherein when the power switching device is on, power from an external power source attached to the second connection device can be modified by the power processing device to be useful to the first connection device.

2. ) The system of claim 1,

wherein the wake from OFF state controller device consists of a normally closed switch device and a regulator device;

wherein the regulator device regulates the power from the first connection device;

wherein the normally closed switch device connects the regulated power from the regulator device to the power switching device.

a wake set device;

an identity device;

wherein the identity device initially presents itself as requiring power from an external device attached to the first connection device;

wherein the wake set device uses power from the first connection device to turn on the power switching device;

wherein the identity device, upon establishing internal power on the power processing device, modifies the identity to disable power from the external device attached to the first connection device.

4. ) The system of claim 3,

wherein the identity device incorporates a wireless communication protocol.

5. ) The system of claim 3,

wherein the identity device is a system comprising:

an identity switching device;
