After several patents filed in this regard, it is clear that Apple is investigating ways to protect your iPhone from falls. The last patent, filed last Thursday with the name “housing for electrical devices“, Describes a security system that deploys some cushioned retractable protectors that leave the corners of the iPhone when the integrated sensors detect a possible impact. This patent works in a similar way to another patent they filed to protect the front panel. The patent protects against falls on hard surfaces (which soft ones are dangerous?). The iPhone would use the accelerometer, gyroscope, cameras and microphones (one specifically for echolocation), among others, and that are configured to control the movement of the device to detect changes in speed, acceleration and other movements characteristic of a fall.
