    Abstract: Electronic devices and accessories such as headsets for electronic devices are provided. A microphone may be included in an accessory to capture sound for an associated electronic device. Buttons and other user interfaces may be included in the accessories. An accessory may have an audio plug that connects to a mating audio jack in an electronic device, thereby establishing a wired communications link between the accessory and the electronic device. The electronic device may include power supply circuitry for applying bias voltages to the accessory. The bias voltages may bias a microphone and may adjust settings in the accessory such as settings related to operating modes. User input information may be conveyed between the accessory and the electronic device using ultrasonic tone transmission. The electronic device may also gather input from the accessory using a voltage detector coupled to lines in the communications path.

    Abstract: Methods and apparatus for providing device detection and operational mode negotiation entirely over extant high-speed data bus pins or terminals. In one exemplary embodiment, methods and apparatus are disclosed enabling detection, negotiation and serial/video data transfer over USB 2.0 data interface pins in order to consolidate pin count on the interface and associated connector. Existing USB detection mechanisms are also leveraged to the maximum extent so as to eliminate the need for additional detection protocols. This approach allows for smaller connector and parent device form factor, while still maintaining all of the functional capabilities required for that interface. The breadth of USB-capable devices supported by such an interface is also markedly improved over prior art techniques.

    Abstract translation: 完全通过现有高速数据总线引脚或终端提供器件检测和操作模式协商的方法和装置。 在一个示例性实施例中,公开了通过USB 2.0数据接口引脚进行检测,协商和串行/视频数据传输的方法和装置,以便在接口和相关连接器上整合引脚数。 现有的USB检测机制也被最大程度地利用,以免消除额外的检测协议。 这种方法允许更小的连接器和父设备外形,同时仍然保持该接口所需的所有功能。 由这种接口支持的支持USB功能的设备的宽度也比现有技术显着提高。
