Abstract

Disclosed are structures, methods and systems for wireless devices that are configured to allow the transmission of light through an enhanced antenna break for a wide variety of purposes. In an illustrative embodiment, an antenna break is configured to allow the passage of both wireless communication signals and light, such as to notify the user of one or more conditions. The light transmission can be integrated with other functions of the wireless device, such as to provide a flash for operation of a camera, to provide a light source for scanning or 3D sensing, to provide light in conjunction to acoustic or vibration output, or to sense light for other integrated functions.
