    Abstract: The disclosed embodiments relate to a system for transmitting data from a sensor to a host. During operation, the system periodically samples data at the sensor with reference to a sensor clock. Next, the system uses the sensor clock to transmit the data from the sensor to the host, wherein the host operates with reference to a host clock, which is different than the sensor clock. During the transmission process, the system embeds a clock in the data, wherein the embedded clock can be extracted at the host and used to receive the transmitted data. In some embodiments, transmitting the data involves using voltage-mode signaling. In other embodiments, transmitting the data involves using current-mode signaling.

    Abstract translation: 所公开的实施例涉及用于将数据从传感器传送到主机的系统。 在运行期间,系统周期性地参考传感器时钟在传感器处采集数据。 接下来,系统使用传感器时钟将数据从传感器传送到主机,其中主机参考与传感器时钟不同的主机时钟来进行操作。 在传输过程中,系统在数据中嵌入时钟,其中可以在主机处提取嵌入式时钟并用于接收所发送的数据。 在一些实施例中,传输数据涉及使用电压模式信令。 在其他实施例中,发送数据涉及使用当前模式信令。

    Abstract: Some embodiments of the disclosure provide systems and methods of detecting headphone orientation. The systems and methods described herein may be used, for example, to determine which ear cup of a pair of headphones is positioned on which ear of a user. By making this determination, stereophonic audio signals may be divided into their left audio channel signal and right audio channel signal components and transmitted to the proper ear cup. In another example, the systems and methods described herein may be used to determine when a pair of headphones are being worn on a user's head and/or are removed from a user's head. By determining when the headphones are being worn, the headphones may be able to automatically pause an audio signal and/or power off when a transition from on-head to off-head is detected.
