Abstract: A system and a method are disclosed for selectively activating access by an application to a camera. In an embodiment, a physical object provider receives a request, from an application installed on a mobile device of a user, for a physical object to be delivered to an address corresponding to the user, wherein access by the application to a camera of the mobile device is de-activated. Responsive to receiving the request, the physical object is caused to be delivered to the address. The physical object provider receives a notification that the physical object has been delivered to the address, and transmits an instruction to the application to activate access by the application to the camera. The physical object provider receives, from the application, an image captured by the camera, and publishes the image to an additional user.

Abstract: Provided are wearable lights or lights that can be attached to accessories when carrying out activities in low-light or no-light conditions. The wearable lights incorporate a portion of non-magnetic material with an internal chamber with a low friction internal surface that is surrounded by a copper coil. A magnet is passed through the internal chamber, allowing the copper coil to break the magnetic fields of the magnet, which creates a burst of electrical current. The current is used to emit light through LED's. Movement of the wearer/user generates the movement of the magnet in the internal chamber, and repelling magnets at the top and bottom of the internal chamber assist the magnet in moving back and forth through the chamber. The inventive device can be adapted for use in many sporting and other applications, such as in running shoes, running belts, rucksacks and as stand-alone wearable lights.
