    Abstract: A wireless transmitter device is configurable and operable to transfer energy to multiple receiver devices at the same time. The transmitter device includes at least one layer of discrete transmitter coils. The wireless transmitter device is configured to enable one or more sections of a charging surface to transfer energy by selectively choosing one or more discrete transmitter coils in the wireless transmitter device based on the position of the receiver device on the charging surface. The size and shape of each section of the charging surface that is used to transfer energy to a receiver device can change dynamically based on each receiver device. Additionally, the process of transferring energy to each receiver device may be adjusted during energy transfer based on conditions specific to each receiver device.

    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，则发射机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第一占空比步骤的一个或多个周期将能量传送到接收机设备来产生平均占空比。 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，并传送能量。

    Abstract: A receiver device in a coupled coil system for wireless energy transfer includes a receiver coil and a load device operatively connected to the receiver coil and configured to receive a signal from the receiver coil. As one example, the load device is a rechargeable battery. An adjusting filter is included in the receiver device and is operatively connected between the receiver coil and the load device. The adjusting filter can be used to transform the effective resistance or impedance of the load as presented to the transformer during energy transfer so that the effective resistant or impedance of the load is maintained at a substantially constant level, and the signal received by the load device is maintained at a substantially constant level.
