Aspects of the present disclosure involve a transparent structure. The structure may include at least one light source, a transparent light-carrying guide layer optically coupled with the at least one light source. The structure may include refractive layers where a light absorbing feature is operably associated with the light-carrying guide layer to absorb any light not internally reflected in the light guide layer, at least adjacent the light source.

Electronic devices may be provided with compasses for detecting the Earth's magnetic field. Electronic devices may be provided with electronic components that generate interfering magnetic fields for the compass. Electronic components may be coupled between a power supply line and a power return line on a printed circuit. The power return line may be configured to generate a compensating magnetic field to counteract the interfering magnetic fields. The power return line may be formed parallel to the power supply line. The power supply line may have multiple branches equidistant from the compass. The power return line may have a portion closer to the compass than the power supply line and the electronic component. The power return line may have multiple branches, may be provided with resistors on each branch and may include a portion of a circular loop the runs around the compass on the printed circuit board.

Electronic devices may be provided with compasses for detecting the Earth's magnetic field. Electronic devices may be provided with other electronic components. A compass may include a magnetic sensor and control circuitry configured to apply offsets or other compass calibration data to compass data to compensate for magnetic interference from the other electronic components. Other electronic components may include components such as cameras, auto-focus lens mechanisms, light sources, and displays. The control circuitry may be configured to apply compass calibration data that is specific to an electronic component and that is specific to an operational status of the component. The control circuitry may be configured to recognize a replacement electronic component and revert to an average compass calibration correction. The control circuitry may be configured to output interference-corrected compass data to applications running on the electronic device.

A portable device includes: an enclosure, one or more processors for executing one or more programs; one or more actuators in or on the enclosure for generating mechanical vibrations; one or more sensors in or on the enclosure for detecting mechanical vibrations; and memory storing one or more programs for execution by the one or more processors. The device analyzes one or more signals produced by the one or more sensors with respect to mechanical vibrations to determine a holding state of the portable device, and conditionally modifies operation of at least one application executed by the one or more processors in accordance with the determined holding state.
