Apple patent filing may lead to iPhone that predicts your needs

Your iPhone could one day switch to vibrate mode, adjust its own volume, and wake from sleep mode without you lifting a finger.

A patent application published today by the U.S. Patent and Trademark Office suggests a phone or other device empowered with "situational awareness." Dubbed "Electronic device with automatic mode switching," the filing describes ways that the device can automatically perform certain tasks based on different conditions.

Filed in September 2011, the Apple patent application lays out the technology for a variety of devices, including mobile phones and media players. Using such embedded sensors, a device could detect external noises, temperatures, lighting conditions, and time of day, and then react accordingly.
