Abstract
A system is described that turns off a high power, power supply when a device no longer needs high power. A low power, power supply or a rechargeable battery provides power to determine when the device again needs high power. The low power supply consumes a minimum possible power when the device does not need high power and the power rechargeable battery is not charged. That is, the high power and low power, power supplies are turned on or off based on the real time power consumption need of the device and the charged state of the battery. The power need of the device is monitored by a current shunt monitoring circuit and a control signal monitoring circuit.
Claims26
An apparatus, comprising:
- first means for powering an electronic device, wherein the first means for powering is associated with a high-power mode of operation of the apparatus;
- means for monitoring when the electronic device requires power;
- second means for powering the means for monitoring, wherein the second means for powering is associated with a low-power mode of operation of the apparatus;
- and
- means for turning off the first means for powering when the electronic device does not require the power.
An apparatus, comprising:
- first means for powering an electronic device, wherein the first means for powering is associated with a stand-by mode of operation;
- means for monitoring when the electronic device requires power;
- second means for powering the means for monitoring, wherein the second means for powering is associated with a power-off mode;
- and
- means for turning off the first means for powering when the electronic device does not require the power.
A memory device having instructions stored thereon that, in response to execution by a control device, cause the control device to perform operations comprising:
- monitoring a power requirement of an electronic device, wherein power for said monitoring is provided by a first power supply;
- identifying a change to the power requirement, wherein the power requirement is provided by a second power supply;
- and
- turning off the second power supply in response to identifying the change to the power requirement.
A method, comprising:
- recharging a battery during a high-power mode of operation associated with an electronic device, wherein the battery is recharged by an AC to DC power supply configured to provide power to the electronic device;
- determining when the battery is recharged;
- receiving a control signal indicating that the power consumed by the electronic device is zero;
- and
- in response to receiving the control signal, turning off the AC to DC power supply during a power-off mode of operation when the battery is recharged.
An apparatus, comprising:
- an AC to DC power supply configured to provide power to an electronic device;
- and
- a control device configured to:
- monitor a state of charge of a battery during a high-power mode of operation associated with the electronic device;
- receive a control signal indicating that the power consumed by the electronic device is zero;
- and
- turn off the AC to DC power supply during a power-off mode of operation, in response to receiving the control signal, when the battery is fully charged.
A method, comprising:
- monitoring a power requirement of an electronic device, wherein power for said monitoring is provided by a first power supply;
- identifying a change to the power requirement, wherein the power requirement is provided by a second power supply;
- and
- turning off the second power supply in response to identifying the change to the power requirement.
