Wake from off state power system
First Claim
1. A wake from off state power adapter system comprising:
- a first connection device;
a wake reset device connected to said first connection device;
a wake from off state controller device connected to said wake reset device and said first connection device;
a power processing device connected to said wake reset device;
a power switching device connected to said wake from off state controller device and said power processing device;
a second connection device connected to said power switching device;
wherein when the power switching device is off, no power from the second connection device is consumed by the wake from off state 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 wake from off state 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 configured by the power processing device to be used by the wake from off state power adapter system and the first connection device.

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.

12. A wake from off state controller device comprising:
-
a wake from off link; an on-off link, which is activated using said wake from off link; an identity device connected to said wake from off link; a wake set device connected to said wake from off link and which activates said on-off link using said wake from off link; wherein when in an off state, no power is consumed by the wake from off state controller device; wherein the identity device presents a first identity that requests power from an external device to the wake from off link; wherein the wake set device uses power from the wake from off link to initiate a wake from off signal on the on-off link; wherein the identity device modifies the first identity to a second identity to disable power from the external device. - View Dependent Claims (13, 14)

15. An identity device comprising:
-
an identity switching device; an identity1 device connected to said identity switching device; an identity2 device connected to said identity switching device; a switch driver device connected to said identity switching device; a timing device connected to said switch driver device; a first connection device connected to said identity switching device, said identity2 device, said switch driver device and said timing device; wherein the identity switching device requires no power to present identity1 device to the first connection device; wherein the timing device establishes a delay time for the identity switching device to present identity2 device to the first connection device. - View Dependent Claims (16, 17, 18, 19)
