摘要： 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.

摘要： Electronic devices and accessories for electronic devices such as headsets are provided. The electronic devices may produce audio output. The headsets may include earbuds with speakers that play the audio output for a user while the earbuds are located in the user's ears. Circuitry in an electronic device and a headset may be used in evaluating how well the earbuds are sealed to the user's ears. In response to seal quality measurements, informative messages can be generated for the user, overall earbud volume may be increased, balance adjustments may be made to correct for mismatched balance between left and right earbuds, equalization settings may be adjusted, and noise cancellation circuitry settings can be changed. Electrical impedance measurements and acoustic measurements can be used in evaluating seal quality.

摘要： Methods and apparatus for sampling and determining the frequency of periodic digital signals. An exemplary digital sampling apparatus includes a polyphase sampling apparatus configured to sample a periodic digital signal according to a polyphase clock system having multiple phases. The multiple phases provided by the polyphase clock system are successively distributed in time so that consecutive phases have a periodic phase difference. By using a polyphase clock system, a sampling rate that is equivalent to a sampling clock having a period equal to the phase difference in time between phases of the polyphase clocks is realized. Accordingly, the effective sampling rate of a given periodic digital signal can be increased, or the sampling of higher frequency periodic digitals signals can be achieved, while the underlying logic circuitry used to capture the samples is clocked at a much lower rate.

摘要： Electronic devices and equipment may communicate over a wired communications path. The wired communications path may include one or more wires and may be associated with a headphone cable. Data may be conveyed in the form of a digital data stream containing multiple traffic channels. The digital data stream may include superframes, each of which has multiple frames of data. The frames of data may each contain a number of data slots. Some of the slots in a superframe may be used exclusively by a particular one of the traffic channels. Boundary slots may be shared between traffic channels. Data interface circuitry may implement a data dispersion algorithm that determines the pattern in which data from each traffic channel is distributed within each boundary slot. Transmitting data interface circuitry may merge traffic channels into a single data stream. Receiving data interface circuitry may reconstruct the traffic channels.

摘要： Solar power tracking techniques are described herein. In one aspect of the invention, a solar power tracking apparatus includes, but is not limited to, a voltage converter and a controller coupled to the voltage converter. The voltage converter includes an input capable of being coupled to a solar power source and an output capable of being coupled to an electronic load, such as, for example, a portable electronic device. The voltage converter is configured to monitor or detect an amount of power drawn by the electronic load at the output of the voltage converter. In response to the monitored power drawn, the controller is configured to control the voltage converter to reduce amount of power to be drawn subsequently if the monitored amount of power exceeds a predetermined threshold. As a result, the output voltage from the solar power source is maintained within a predetermined range. Other methods and apparatuses are also described.

摘要： A multiple path angle modulator includes a closed secondary loop added to a main control loop to automatically adjust a scaling factor related to high frequency gain. The main control loop is configured as a primary path to process the low frequency portion of the angle modulation signal, and the secondary loop is configured as an auxiliary path to process the high frequency portions of the angle modulation signal. The secondary loop senses calibration information and uses it to continuously calibrate the gain within the modulation loop in real time while the system performs its primary operation, thereby eliminating the need for a system shut down or calibration specific timing, such as a lapse time, to balance the modulation paths. Calibration is continuously performed as a background process. The angle modulator is applicable to all modulation type systems.
