2. Title: Method and apparatus for determining position and orientation of a moveable object using accelerometers File date: March 20, 1997 Claims: A method for generating computer simulation signals in response to orientation of a moveable object from a plurality of accelerometers mounted on the moveable object. Generating orientation signals associated with the movement of the object in three degrees of freedom as a function of the linear acceleration signals. #1 - US Patent 5615132

3. Similarities Using accelerometers to measure a variety of calculations. Determines orientation in three degrees of freedom Differences We are only using one 3-axis accelerometer. They use 3 single axis accelerometers spaced 120°apart Solution : No literal infringement #1 - US Patent 5615132

4. Title: Finger mounted computer input device File date: December 3, 1996 Claims: Providing pressure sensing means proximate to the tip of a finger of a hand for generating a pressure signal corresponding to the pressure of the tip of the finger against a surface. Transmitter is attachable proximate to the back of the hand. #2 - US Patent 5581484

5. Similarities : Using pressure sensors for creating pressure data. Transmitting data wirelessly Differences : Input is not being sent to a computer Solution : Move position of XBee to anywhere not on the back of the hand. Licensing for finger pressure sensing capabilities. #2 - US Patent 5581484

6. Title: Music jukebox File date: October 30, 2007 Claims: Time remaining displayed Display master song list The player is configured such that the memory stores a library of songs. Configured to amplify audio output signals produced during playing which are transmitted to the headphone jack. #3 - US Patent 7289393

7. Similarities : Audio is output to headphone jack. Stores audio samples Differences : No time displayed Cannot display master song list Solution : By doctrine of equivalents, we may need a license for storage and output to headphone methods. #3 - US Patent 7289393
