Patent ID: 8489213

Claim:
A portable digital media device, including: a storage device; a controller coupled to the storage device; a buffer memory; and a force sensor coupled to the controller, the force sensor being configurable to determine whether force has been exerted on the portable digital media device, the force sensor being one of: connectable externally to the storage device; and incorporable into the storage device in a manner such that when incorporated into the storage device, the force sensor is configurable for determining force experienced by the storage device when force is exerted on the portable digital media device, wherein when the force sensor determines that force has been exerted on the portable digital media device, the controller is configured to at least one of cut power to the portable digital media device and cut power to only the storage device, and the buffer memory is configurable to reduce activity of the storage device such that when power is to be cut, power can be more quickly cut; wherein the force sensor is further configurable to continuously log data in a manner so as to count a number of steps a moving user takes using the portable digital media device; wherein the controller is configurable for monitoring for a pre-determined time, where spikes are regularly detected in an axis selected from the group consisting of: x, y, and z; wherein the controller is further configurable for tagging that axis as the designated axis and increasing a step count by one whenever a spike in the designated axis is obtained from the force sensor; and wherein the controller is yet further configurable for selecting a song from the storage device in the media device with a beat frequency that matches the detected spike frequency for the user.
