Abstract: In an inductive energy transfer system, the phase of a signal that is applied to a transmitter coil to transfer energy is adjusted while energy is transferred from the transmitter device to a receiver device. The phase of the signal can be adjusted by changing a state of a DC-to-AC converter from a converting state to a non-converting state. The DC-to-AC converter outputs a signal that is applied to the transmitter coil when the DC-to-AC converter is in a converting state. A signal is not applied to the transmitter coil when the DC-to-AC converter is in a non-converting state.

Abstract: A method of scanning a touch sensor panel while the touch sensor panel is coupled to a power adapter is disclosed. The power adapter can charge a battery of a device, but can also introduce or add noise during the process of charging the battery. To prevent adverse effects to the touch sensor panel, while the device is charging, the touch controller can time multiplex touch scan periods and inductive charging periods and can discard touch scans or touch images affected by the noise. Determining whether a touch scan is a bad touch scan can include performing a touch scan across the array of touch pixels and making a determination based on the scan profile. In some examples, the profile can be quantified using different metrics such as the shape, instantaneous slope of tail ends, a full-width half-maximum, and a monotonicity of the curve of the scan profile.

Abstract translation: 公开了一种当触摸传感器面板耦合到电源适配器时扫描触摸传感器面板的方法。 电源适配器可以为设备的电池充电，但是在为电池充电过程中也可能会引入或增加噪音。 为了防止对触摸传感器面板的不利影响，在设备充电时，触摸控制器可以对触摸扫描周期和感应充电周期进行时间复用，并可以丢弃受噪声影响的触摸扫描或触摸图像。 确定触摸扫描是否是不良触摸扫描可以包括在触摸像素阵列之间执行触摸扫描并且基于扫描简档进行确定。 在一些示例中，可以使用不同的度量来定量轮廓，例如形状，尾端的瞬时斜率，全角半最大值以及扫描轮廓曲线的单调性。

Abstract: A dc input circuit receives a dc input voltage. At least four rectification elements are coupled to each other in a diode bridge configuration, where an input of the diode bridge configuration is coupled to the dc input circuit to receive the dc input voltage. At least one of the rectification elements includes a transistor. A decision circuit indicates, as a function of one of collector current and emitter current of the transistor, that the received dc input voltage has normal or reversed polarity. Other embodiments are also described and claimed.

Abstract: A hearable has an audio amplifier circuit coupled to a speaker as a load. The amplifier circuit has current source drive, which attenuates electromagnetically coupled noise of the speaker. In other instances, the amplifier circuit has a first amplifier mode and a second amplifier mode, wherein in the first amplifier mode the amplifier circuit becomes configured to drive the speaker as a voltage source, and in the second amplifier mode the amplifier circuit becomes configured to drive the speaker as a current source. Control logic varies the amplifier circuit between i) the first amplifier mode for larger amplitudes of the audio signal, and ii) the second amplifier mode for smaller amplitudes of the audio signal. Other aspects are also described and claimed.

Abstract: A wireless transmitter device is configurable and operable to transfer energy to multiple receiver devices at the same time. The transmitter device is configured to enable one or more sections of a charging surface to transfer energy by selectively choosing one or more conductive traces in the 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.
