Apparatus and Method for Distributed Standby Power Provision
First Claim
1. An apparatus for providing standby power to a node of a distributed system of devices, comprising:
- a current manager operable to manage supply of current to a device at the node;
a normal current supplier operable to supply normal operating current to the device; and
a super capacitor at the node operable to supply standby operating current to the device under control of the current manager when the normal current supplier fails to supply the normal operating current to the device.

Abstract
An apparatus and method for providing standby power to a node of a distributed system of devices. The apparatus includes: a current manager operable to manage supply of current to a device at the node; a normal current supplier operable to supply normal operating current to the device; and a super capacitor at the node operable to supply standby operating current to the device under control of the current manager when the normal current supplier fails to supply the normal operating current to the device. The apparatus preferably further comprises a switching regulator, operable in electrical communication with the super capacitor and the device, to regulate the standby operating current to the device.
