PROXIMITY SENSOR FOR DEEP SLEEP WAKEUP OF WIRELESS CHARGER |
| 摘要 |
The disclosure relates to a method, apparatus and system for power transmission unit (PTU) having a sensing unit. The sensing unit may be integrated with the PTU to determine when a power receiving unit (PRU) is proximal and awaken the PTU's charging coil. When a PRU is not present, the PTU may be in Deep Sleep state to save power. |

1. A wireless charging apparatus, comprising:
a resonator; a proximity sensor to detect presence of an object proximal to the resonator; a Power Transmission Unit (PTU) to communicate with the resonator and with the proximity sensor, the PTU configured to engage the resonator to generate a magnetic field in response to detected presence of the object. |
