20130218504 | ESTIMATION OF CONVENTIONAL INERTIAL SENSOR ERRORS WITH ATOMIC INERTIAL SENSOR - Embodiments described herein provide for a method for obtaining an inertial measurement. The method includes obtaining multiple contiguous high sample rate readings during a time period from a conventional inertial sensor. Non-contiguous low sample rate reading of accumulated motion are also obtained over the time period from an atomic inertial sensor. One or more observable errors are estimated for the conventional inertial sensor based on comparing the low sample rate reading to the multiple high sample rate readings. A compensated hybrid reading is determined by compensating the high sample rate readings for the one or more observable errors based on the estimating of the one or more observable errors. | 08-22-2013 |

20120210486 | FINGERTIP PROTECTOR FOR A PERSON PLAYING A STRINGED INSTRUMENT - A fingertip covering device for allowing a player of a stringed musical instrument to manipulate the stings with high dexterity while minimizing fingertip damage. The device extends from the fingertip region of the finger to about the distal interphlangeal joint region of the player's finger. The covering is made from a variable-thickness deformable polymer with a maximum thickness at the fingertip, and a minimum thickness at the sides of the finger. The maximum thickness of the covering device is chosen to substantially protect the user's fingertip region from damage caused by string-to-fingertip contact (about 1 mm), while at the same time allowing the user's fingertips to continue to sense the presence of said string. The minimum thickness of the covering device (about 0.3 mm) minimizes contact or interference with neighboring fingers and/or any similar coverings being worn by the neighboring fingers. | 08-23-2012 |
