/**
 *
 * This is the internal implementation of the standard power management
 * policy for managing the power states of non-virtualized devices.
 * Non-virtualized devices are shared using a parameterized Resource
 * interface, and are powered down according to some policy whenever there
 * are no more pending requests to that Resource.  The policy implemented
 * by this component is to power down a device as soon as it becomes free.
 * Such a policy is useful whenever a device has a negligible wake-up
 * latency.  There is no cost associated with waiting for the device to
 * power up, so it can be powered on and off as often as possible.<br><br>
 *
 * Powerdown of the device is done through the <code>AsyncStdControl</code>
 * interface, so this component can only be used with those devices that
 * provide that interface.<br><br>
 *
 * For devices providing either the <code>StdControl</code> or
 * <code>SplitControl</code> interfaces, please use either the
 * <code>StdControlPowerManagerC</code> component or the
 * <code>SplitControlPowerManagerC</code> component respectively.
 * 
 * @author Kevin Klues ([e-mail])
 * @see  Please refer to TEP 115 for more information about this component and its
 *          intended use.
