Sony Corporation recently filed a patent application seeking to protect a pillow that is designed wake the user up at an ideal time, or otherwise after an “awakening point” has been reached. In particular, the pillow includes a series of electrodes that contact the user’s head or scalp and are structured to read the user’s brain wave activity during sleep. The brain wave activity is analyzed by a computer processor, also embedded within the pillow, to determine whether the awakening point has been reached. If so, in one embodiment, an alarm will sound to wake up the user.
