ABSTRACT:
An apparatus and method for cooling an electronic device and generating a vibrational signal to alert a user of a particular state of the electronic device. The apparatus includes a motor having a rotor that is rotatable in first and second opposite directions around a first axis, a cooling flow generator, and a vibrational signal generator. The cooling flow generator is operably connected to the rotor to produce a cooling flow in response to rotation of the rotor in at least one of the first and second directions. The vibrational signal generator is operably connected to the rotor to produce a vibrational output of a first magnitude in response to rotation of the rotor in the first direction, and a vibrational output of a second magnitude less than the first magnitude in response to rotation of the rotor in the second direction. The first magnitude is sufficient to generate a vibrational signal that can be sensed by a user to alert the user of a particular state of an electronic device containing the apparatus.
