NOTIFICATION TECHNIQUES FOR WIRELESS POWER TRANSFER SYSTEMS
First Claim
1. An apparatus, comprising:
- a power transmitting unit (PTU); and
logic, at least a portion of which is in hardware, the logic to initiate an extraneous object detection procedure to check for a presence of extraneous objects within a transfer field of the PTU during operation of the PTU in a power transfer state, and in response to a detection of an extraneous object, send an extraneous object notification message to a power receiving unit (PRU) and determine whether to maintain the PTU in the power transfer state based on a determination of whether the extraneous object comprises a rogue object.

Abstract
Notification techniques for wireless power transfer systems are described. In one embodiment, for example, an apparatus may comprise a power transmitting unit (PTU) and logic, at least a portion of which is in hardware, the logic to initiate an extraneous object detection procedure to check for a presence of extraneous objects within a transfer field of the PTU during operation of the PTU in a power transfer state, and in response to a detection of an extraneous object, send an extraneous object notification message to a power receiving unit (PRU) and determine whether to maintain the PTU in the power transfer state based on a determination of whether the extraneous object comprises a rogue object. Other embodiments are described and claimed.

10. A wirelessly-chargeable device, comprising:
-
a power receiving unit (PRU) to receive power from a power transmitting unit (PTU); and logic, at least a portion of which is in hardware, the logic to receive an extraneous object notification message indicating a presence of an extraneous object within a transfer field of the PTU and in response to receipt of the extraneous object notification message, initiate a user alert procedure to cause presentation of an extraneous object alert. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. At least one non-transitory computer-readable storage medium comprising a set of instructions that, in response to being executed at a wireless power transfer device, cause the wireless power transfer device to:
-
initiate an extraneous object detection procedure to check for a presence of extraneous objects within a transfer field of a power transmitting unit (PTU) of the wireless power transfer device during operation of the PTU in a power transfer state; and in response to a detection of an extraneous object; send an extraneous object notification message to a power receiving unit (PRU); and determine whether to maintain the PTU in the power transfer state based on a determination of whether the extraneous object comprises a rogue object. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
