Abstract: To avoid undesirable electrostatic discharge events while maintaining low leakage currents, earbuds may be provided with controlled electrostatic discharge paths. The discharge paths may include discrete components such as resistors or more distributed resistive components such as resistive elastomers. A resistive elastomer may be incorporated into an interior portion of an earbud between an earbud housing structure and a ground path. A resistive elastomer may also be used in forming an ear bud tip.

Abstract: Peripherals and data processing systems are disclosed which can be configured to interact based upon sensor data. In one embodiment, a peripheral, which is configured to be used with a data processing system, includes an interface to couple the peripheral to the data processing system, and at least one sensor, such as a proximity sensor, to sense a user of the peripheral, and a processor coupled to the interface and to the at least one sensor, wherein the processor configures the peripheral in response to data from the at least one sensor. The peripheral may communicate sensor data from its sensors to the data processing system, which may be a wireless PDA, and the data processing system analyzes the sensor data from its sensors and from the peripheral's sensors to decide how to configure the peripheral and/or the data processing system based on the sensor.

Abstract: Methods and apparatus for processing user events are provided. In particular, one or more sensor modules and processor modules are provided that can be operated to detect user events, such as the pressing of an otherwise mechanical switch. In many electronic devices, touch display screens are provided to the user for interfacing with the device. These displays often must also include one or more mechanical switches to provide necessary functionality. The functionality, however, comes at the cost of reduced aesthetics, and potentially increased manufacturing costs related to fabricating one or more holes in the display substrate. The sensor module disclosed herein can be configured such that collected pressure data can be focused, such as linear expansion data or deflection data. By collecting two different types of focused data, the apparatus can more accurately determine whether a user event has occurred. Additional types of sensors may also be utilized to provide even more reliable results.

Abstract: Methods for operating a portable media device are provided. The method includes determining an orientation angle of the portable media device and a frequency spectrum associated with a motion of the portable media player. Based on the orientation angle and the frequency spectrum, the portable media player can determine a motion status and select a mode of operation based on the motion status. In addition, the method also includes determining whether the portable media player is in a dock, resting on a surface, or being handled by a person. The method further includes determining whether the portable media player is located in a moving vehicle, in a stationary vehicle, being held by a moving person, or being held by a stationary person.

Abstract: An integrated system allows easily creating and using disposable email addresses. The disposable email address is created by an email server, which manages correspondence using the disposable email address to avoid exposing the associated non-disposable email address. Context information may be associated with a disposable email address, where the context information is not visible in email sent using the disposable email address. Expiration information may also be associated with the disposable email address, where the expiration information defines conditions that cause the disposable email address to expire. Should the disposable address be misused, the associated context may allow a user to recognize what correspondent exposed the disposable address to misuse.

Abstract: Systems and methods are provided for calibrating the internal oscillator of a microcontroller from a remote clock source. In some embodiments, an electronic device can request timing information from a third party device using a timing independent signal. The timing information received from the third party device may be used to calibrate the microcontroller clock of the electronic device. In some embodiments, the internal oscillator may be calibrated based on timing information received from multiple third party devices. Once calibrated, the microcontroller may initiate timing dependent communication with other electronic devices using a timing dependent protocol, such as a serial protocol.

Abstract: Connectors for cables such as a 30-pin connector are provided. The connectors may have thermal protection circuits and may carry a power supply voltage and a ground voltage. The thermal protection circuits may disable the power supply voltage when the temperature of the connector exceeds a threshold value. The thermal protection circuits may disable the power supply voltage when liquid is detected in the connector. The thermal protection circuits may disable the power supply voltage permanently or temporarily. In one example, when a cable is reset, the thermal protection circuits may use a record of previous fault events and measurements from thermal and liquid sensors to determine whether to enable or disable the power supply voltage.

Abstract: Power supply devices are provided that can include power regulating circuitry for regulating (e.g., transforming or converting) electric power to be passed to an electronic device. A power supply device can also include control circuitry coupled with the regulating circuitry. The control circuitry can determine when the power supply device is coupled with an electronic device. The control circuitry can control the operation of the regulating circuitry based on whether or not the power supply device is coupled with the electronic device.

Abstract: An adapter may couple an electronic device to a host such as a computer. When coupled in this way, the host may transfer media files to the device. The host may also supply power to the electronic device using power lines in the adapter. The electronic device may have a status indicator such as a light-emitting diode status indicator. The adapter may also have a status indicator. During operation, the electronic device may transmit coded information on the current state of the status indicator in the electronic device by modulating the status indicator or other load in the device at a selected frequency. Control circuitry in the adapter may detect the transmitted state information by monitoring the power lines. The control circuitry may control the status indicator in the adapter so that the status indicator in the adapter replicates the current state of the status indicator in the electronic device.
