1. A wireless power delivery system comprising:
- a wireless power source to provide power to a first information handling system; and
a control module in communication with the wireless power source, the control module configured to detect a presence signal from the first information handling system, to set an output power level for the first information handling system based on the presence signal, to receive a power state signal from the first information handling system, to adjust the output power level based on the power state signal, to detect a change in an amount of power available to the first information handling system, and to send an adjust signal to the first information handling system indicating the change in the amount of power available to the first information handling system, wherein the change in the amount of power available to the first information handling system is based on a priority of the first information handling system as compared to a second information handling system in communication with the wireless power delivery system; and
the first information handling system including a wireless charging pad, the wireless charging pad to detect a presence of a third information handling system, to determine a first power state for the third information handling system, to provide power to the third information handling system based on the first power state, and to combine the first power state with a second power state of the first information handling system to determine a third power state of the first information handling system, wherein the control module is further to provide the third power state to the wireless power source.

Abstract
A wireless power delivery system includes a wireless power source and a control module. The wireless power source provides power to an information handling system. The control module is in communication with the wireless power source, and is configured to detect a presence signal from the information handling system, to set an output power level for the information handling system based on the presence signal, to receive a signal from the information handling system, and to adjust the output power level based on the signal.

6. An information handling system comprising:
-
a wireless charger to receive power from a first wireless charging pad based on a first power state of the information handling system, and to provide the power to the information handling system; and a control module in communication with the wireless charger, the control module configured to detect a change in an operating mode of the information handling system, to determine a second power state for the information handling system in response to the change in the operating mode, to provide the second power state to the first wireless charging pad, to receive an adjust signal from the first wireless charging pad indicating a change in an amount of power available for the information handling system from the first wireless charging pad, and to change the operating mode of the information handling system in response to the change in the amount of power available, wherein the change in the amount of power available to the information handling system is based on a priority of the information handling system as compared to a second information handling system in communication with the wireless power delivery system; and a second wireless charging pad to detect a presence of a third information handling system, to determine a third power state for the third information handling system, to provide power to the third information handling system based on the third power state, and to combine the third power state with the second power state to determine a fourth power state of the information handling system, wherein the control module is further to provide the fourth power state to the second landing pad of the first wireless charging pad. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method comprising:
-
receiving, at a first wireless charging pad, a presence signal from a first information handling system; setting an output power level for the first information handling system based on the presence signal; transmitting power at the output power level to the first information handling system; receiving a power state signal indicating a power state change of the first information handling system; adjusting the output power level based on the power state signal; transmitting the power at the adjusted output power level to the first information handling system; detecting a change in an amount of power available for the first information handling system; sending an adjustment signal to the first information handling system indicating the change in the amount of power available to the first information handling system, wherein the change in the amount of power available to the first information handling system is based on a priority of the first information handling system as compared to a second information handling system in communication with the wireless charging pad; detecting, at a second wireless charging pad of the first information handling system, a presence of a third information handling system; determining a first power state for the third information handling system; providing power to the third information handling system based on the first power state; and combining the first power state with a second power state of the first information handling system to determine a third power state of the first information handling system, wherein the control module is further to provide the third power state to the first wireless charging pad. - View Dependent Claims (13, 14)
