Abstract: A receiver device in an inductive energy transfer system can include a touch sensing device. If the input surface of the touch sensing device is touched, a transmitter device can periodically stop transferring energy to allow the touch sensing device to sense touch samples while inductive energy transfer is inactive. Additionally or alternatively, a transmitter device can produce an averaged duty cycle by transferring energy to the receiver device for one or more periods at a first duty cycle step and for one or more periods at different second first duty cycle step. Additionally or alternatively, a transmitter device can reduce a current level received by a DC-to-AC converter if the current received by the DC-to-AC converter equals or exceeds a threshold. Additionally or alternatively, a transmitter device can ping a receiver device and transfer energy only after a response signal is received from the receiver device.

Abstract translation: 感应能量传递系统中的接收器装置可以包括触摸感测装置。 如果触摸感测装置的输入表面被触摸，则发射器装置可以周期性地停止传送能量，以允许触摸感测装置感测触摸样本，同时感应能量传递不活动。 附加地或替代地，发射机设备可以通过在第一占空比步骤和在不同的第二占空比步骤的一个或多个周期将功率传送到接收机设备来产生一个或多个周期的平均占空比。 另外或替代地，如果由DC-AC转换器接收的电流等于或超过阈值，则发射机设备可以降低DC-AC转换器接收的电流电平。 附加地或替代地，发射机设备可以仅在从接收机设备接收到响应信号之后对接收机设备进行ping通和传送能量。

Abstract: A method for operating an inductive energy transfer system that includes a transmitter device and a receiver device can include the transmitter device transmitting (500) a ping during a first time period, and within a given time period after the first time period, the transmitter device detects (504) the receiver device is transmitting a signal. The transmitter device may then extend (508) the given time period, and the transmitter device can determine (510) if it receives a complete signal from the receiver device. If the transmitter device receives a complete signal, the transmitter device can transfer (512) energy to the receiver device based on the receipt of the complete signal.
