Apple Patents Technology To Disable iPhone Cameras At Concerts

In the description of one of Apple’s new patents:

For example, an infrared emitter can be located in areas where picture or video capture is prohibited, and the emitter can generate infrared signals with encoded data that includes commands to disable the recording functions of devices. An electronic device can then receive the infrared signals, decode the data and temporarily disable the device’s recording function based on the command.

I really hope this is a patent Apple never, ever brings to life.
