1. A method for controlling power usage of a reporting device associated with an asset comprising:
- determining by a reporting device whether said reporting device is in a sleep mode or an active mode;
in response to determining said reporting device is in said sleep mode, said reporting device maintaining said sleep mode;
monitoring by said reporting device at least one state associated with said reporting device;
in response to said reporting device determining a state change associated with said reporting device, said reporting device comparing said state change to a state threshold value range;
provided said state change is outside said state threshold value range, powering up said reporting device to said active mode; and
powering down said reporting device to said sleep mode in response to reporting said state change to an asset manager.

Abstract
A system and method for controlling power usage of a reporting device associated with an asset is disclosed. According to one embodiment, a method determines whether the reporting device is in a sleep mode or an active mode and in response to determining the reporting device is in the sleep mode, the method maintains the sleep mode and in response to determining a state change associated with the reporting device, the method powers up the reporting device to the active mode.

10. A method for power state independent asset management comprising:
-
determining by a reporting device whether said reporting device is in a sleep mode or an active mode; maintaining said sleep mode in response to determining said reporting device is in said sleep mode; detecting by a reporting device, an asset moving from a first position to a second position; comparing by said reporting device a distance between said first position and said second position to a threshold distance value; provided said reporting device associated with said asset is in a sleep mode, powering up said reporting device to an active state from a sleep state in response to said reporting device determining a state change of a state monitored by said reporting device is outside a state threshold value range and provided said distance is greater than said threshold distance value, said method further comprising powering up said reporting device to an active mode and reporting said moving to an asset manager; provided said reporting device is in said active mode, said method further comprising reporting said moving to said asset manager; and powering down said reporting device to said sleep mode in response to said reporting said moving to said asset manager. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A system for power state independent asset management comprising:
-
a position determiner for determining a first position of a reporting device associated with an asset; a reporter for wirelessly reporting said first position to an asset manager; and a power state controller of a reporting device for maintaining a sleep mode in response to determining said reporting device is in said sleep mode and for powering up said reporting device to an active state from a sleep state in response to said reporting device determining a state change of a state monitored by said reporting device is outside a state threshold value range and for powering down said reporting device to said sleep state in response to said reporting. - View Dependent Claims (18, 19, 20, 21)
