In iOS 8, Apple is adding some new Core Location features that let app developers get precise indoor positioning data from an iOS device’s sensors and it’s even letting venues contribute by signing-up to get help enabling indoor positioning. We first exclusively detailed the new feature last year, which taps into the iPhone’s M7 processor and uses WiFi technologies to provide extremely accurate indoor mapping and navigation features to developers. expand full story

According to an Apple patent application published by the U.S. Patent and Trademark Office and detailed by PatentlyApple, Apple is at the very least conceptualizing a device that sports a removable back panel for easily replaceable components such as lenses or optical solutions.
While it is unclear whether the invention would be used in a standalone camera, next-generation iPod or iPhone, or a different device entirely, the patent detailed several methods of upgrading a device with supplementary optics:
The digital imaging subsystem is typically enclosed within the case of the device to protect the digital imaging subsystem. The enclosure generally prevents direct access to the lens of the digital imaging subsystem for the purpose of providing any sort of supplementary optics, especially if the supplementary optics must be precisely aligned with the image sensor… It would be desirable to provide a structure for a compact device that allows the end user to reconfigure the optical arrangement of the device while retaining the benefits of assembling the device using a pre-assembled digital imaging subsystem.
Apple detailed several features that could be added through the easily swappable supplementary optics, including: improved zoom capabilities, better shutter control, removable close-up lenses, and the addition of motion sensors, flashes, or a lens baffle. As an example, the report explained a removable IR cut-off filter that would allow “capturing black and white images at very low light levels. Without the IR-cut filter the camera’s light sensitivity may extend to 0.001 lux or lower.” The report also broke down how the removable back panels could be implemented:
