Abstract
A wireless charging device includes a wireless transmitter with an electromagnetic emitting portion. The wireless charging device also includes a seat having a surface and at least one protrusion from the surface. The seat accommodates at least one wireless power receiving device. The seat has an active area that contains the electromagnetic emitting portion. The at least one protrusion is configured as a guide for two sides of the at least one wireless power receiving device for placement over the active area. The placement of the at least one wireless power receiving device over the active area enables transferring of power to the at least one wireless power receiving device.
Claims29
A wireless power transmitting device comprising:
- a wireless transmitter with an electromagnetic-energy emitting portion;
- and
- a seat having a first structure, a second structure, and an active area that contains the electromagnetic-energy emitting portion,
- wherein the first structure and the second structure are configured to align at least one wireless power receiving device in a first direction and a second direction for placement, over the active area, of the at least one wireless power receiving device and to enable an unobstructed view of at least one surface of the at least one wireless power receiving device upon alignment of the at least one wireless power receiving device over the active area,
- wherein the first structure is further configured to align the at least one wireless power receiving device over the active area in the first direction while the at least one wireless power receiving device is moved in the second direction,
- wherein the second structure is further configured to align the at least one wireless power receiving device over the active area in the second direction while the at least one wireless power receiving device is moved in the first direction,
- wherein the first direction is substantially perpendicular to the second direction, and
- wherein the placement of the at least one wireless power receiving device over the active area enables transferring of power to the at least one wireless power receiving device.
An apparatus comprising:
- means for wirelessly transmitting electromagnetic energy to a wireless receiver of an electronic device to charge the electronic device;
- means for aligning the wireless receiver in a first direction over an active area of the means for wirelessly transmitting electromagnetic energy while the electronic device is moved in a second direction and for providing access to an extent of a front surface of the electronic device upon contact of the electronic device with the means for aligning the wireless receiver in the first direction;
- and
- means for aligning the wireless receiver in the second direction over the active area of the means for wirelessly transmitting electromagnetic energy while the electronic device is moved in the first direction and for providing access to the extent of the front surface upon contact of the electronic device with the means for aligning the wireless receiver in the second direction;
- wherein the first direction is substantially perpendicular to the second direction.
