Patent Images
1. An electronic device, comprising:
- an optical emitter configured to emit an optical signal toward a wireless charging device;
an optical detector configured to detect the wireless charging device by detecting the optical signal in response to the optical signal propagating through a portion of the wireless charging device;
a processing device operably connected to the optical detector and configured to;
detect an initial engagement with the wireless charging device as a result of the optical detector detecting the wireless charging device; and
in response to the detected initial engagement with the wireless charging device, determine that the wireless charging device is not supplying power to the electronic device; and
an alert unit operably connected to the processing device and configured to produce an alert in response to receiving, from the processing device, an alert signal indicating that the wireless charging device is not supplying power to the electronic device.

Abstract
An electronic device may be configured to detect an external charging device when the external charging device is initially engaged with, or connected to, the electronic device. The electronic device, or an alert unit operably connected to the electronic device, can produce one or more alerts for the user if the charging device is in an unpowered state. The alert or alerts can be provided to the electronic device engaged with the charging device and/or to another electronic device or alert unit that is in communication with the electronic device that is engaged with the charging device.

7. A method for operating an electronic device, comprising:
-
emitting, by an optical emitter of the electronic device, an optical signal toward a wireless charging device; detecting an initial engagement with the wireless charging device as a result of an optical detector of the electronic device detecting the optical signal in response to the optical signal propagating through a portion of the wireless charging device; in response to detecting the initial engagement with the wireless charging device, determining that the wireless charging device is not supplying power to the electronic device; and producing an alert in response to determining that the wireless charging device is not supplying power to the electronic device. - View Dependent Claims (8, 9, 10)
