Abstract

Methods and apparatus relating to enhanced wireless charging through active cooling are described. An embodiment integrates wireless charging with active cooling functionality to improve wireless charging efficiency, as well as overall system performance by mitigating thermal energy transfer between a charging pad and a mobile computing device. Other embodiments are also disclosed and claimed.

First claim

1 . An apparatus comprising:
logic, the logic at least partially comprising hardware logic, to cause modification to a wireless power level of a wireless charging transmitter based at least in part on one or more temperature values, wherein the one or more temperature values are to be detected by one or more sensors that are to be proximate to one or more components of a portable computing device.

2 . The apparatus of claim 1 , wherein the portable computing device is to comprise the logic.

3 . The apparatus of claim 1 , wherein the logic is to cause modification to the wireless power level of the wireless charging transmitter based at least in part on an indication that the portable computing device is coupled to a wireless charging pad that is to comprise the wireless charging transmitter.

4 . The apparatus of claim 1 , comprising logic to cause modification to speed of one or more fans, coupled to a wireless charging pad, based at least in part on one or more of: a docking status of the portable computing device, the one or more temperature values, ambient noise, a current performance level of the portable computing device, one or more hotspots, a battery charge level, and one or more wireless charging pad temperature values to be detected by one or more wireless charging pad sensors that are to be proximate to one or more components of a wireless charging pad.

5 . The apparatus of claim 1 , further comprising one or more antennae to receive electromagnetic waves from the wireless charging transmitter.

6 . The apparatus of claim 1 , wherein a wireless charging pad is to comprise the wireless charging transmitter.

7 . The apparatus of claim 1 , wherein the portable computing device is to comprise one or more of: a System On Chip (SOC) device; a processor, having one or more processor cores; a flat panel display device, and memory.

8 . The apparatus of claim 1 , wherein the portable computing device is to comprise one of: a smartphone, a tablet, a phablet, a UMPC (Ultra-Mobile Personal Computer), a laptop computer, an Ultrabook™ computing device, and a wearable device.

9 . The apparatus of claim 1 , wherein one or more of the logic, a processor having one or more processor cores, the one or more sensors, and memory are on a single integrated circuit die.

10 . An apparatus comprising:
logic, the logic at least partially comprising hardware logic, to cause a wireless charging pad to modify speed of one or more fans, coupled to the wireless charging pad, based at least in part on a docking status of a portable computing device.

11 . The apparatus of claim 10 , wherein the portable computing device is to comprise the logic.

12 . The apparatus of claim 10 , wherein the logic is to cause modification to a wireless power level of a wireless charging transmitter of the wireless charging pad based at least in part on one or more temperature values, wherein the one or more temperature values are to be detected by one or more sensors that are to be proximate to one or more components of the portable computing device.

13 . The apparatus of claim 10 , wherein the logic to cause modification to the speed of the one or more fans based at least in part on one or more of: ambient noise, a current performance level of the portable computing device, one or more hotspots, a battery charge level, and one or more temperature values to be detected by one or more sensors that are to be proximate to one or more components of the portable computing device.

14 . The apparatus of claim 10 , further comprising one or more antennae to receive electromagnetic waves from a wireless charging transmitter of the wireless charging pad.

15 . The apparatus of claim 10 , wherein the portable computing device is to comprise one or more of: a System On Chip (SOC) device; a processor, having one or more processor cores; a flat panel display device, and memory.

16 . The apparatus of claim 10 , wherein the portable computing device is to comprise one of: a smartphone, a tablet, a phablet, a UMPC (Ultra-Mobile Personal Computer), a laptop computer, an Ultrabook™ computing device, and a wearable device.

17 . The apparatus of claim 10 , wherein one or more of the logic, a processor having one or more processor cores, one or more sensors, and memory are on a single integrated circuit die.

18 . An apparatus comprising:
logic, the logic at least partially comprising hardware logic, to cause modification to a wireless power level of a wireless charging transmitter based at least in part on one or more temperature values, wherein the one or more temperature values are to be detected by one or more sensors that are to be proximate to one or more components of a wireless charging pad.

19 . The apparatus of claim 18 , wherein the wireless charging pad is to comprise the logic.

20 . The apparatus of claim 18 , wherein the logic is to cause modification to the wireless power level of the wireless charging transmitter based at least in part on an indication that a portable computing device is coupled to the wireless charging pad.

21 . The apparatus of claim 18 , comprising logic to cause modification to speed of one or more fans, coupled to the wireless charging pad, based at least in part on one or more of:
a docking status of a portable computing device, the one or more temperature values, ambient noise, a current performance level of the portable computing device, one or more hotspots, a battery charge level, and one or more device temperature values to be detected by one or more device sensors that are to be proximate to one or more components of the portable computing device.

22 . The apparatus of claim 18 , further comprising one or more antennae to transmit electromagnetic waves from the wireless charging transmitter.

23 . An apparatus comprising:
logic, the logic at least partially comprising hardware logic, to cause modification to speed of one or more fans, coupled to a wireless charging pad, based at least in part on a docking status of a portable computing device.

24 . The apparatus of claim 23 , wherein the wireless charging pad is to comprise the logic.

25 . The apparatus of claim 23 , wherein the logic is to cause modification to a wireless power level of a wireless charging transmitter of the wireless charging pad based at least in part on one or more temperature values, wherein the one or more temperature values are to be detected by one or more sensors that are to be proximate to one or more components of the portable computing device or one or more components of the wireless charging pad.
