Stabilizing unintentional muscle movements
First Claim
1. A human tremor compensation system, comprising:
- a stabilization unit including;
a base portion adapted to be held in a user'"'"'s hand and having a motion-generating mechanism in an interior of the base portion, wherein the motion-generating mechanism includes an actuator; and
an implement portion coupled by an attachment arm to the motion-generating mechanism, wherein the motion-generating mechanism is coupled to move the attachment arm and the implement portion relative to the base portion;
at least one remote non-contact position sensor external to and not in physical contact with the stabilization unit, wherein the non-contact position sensor can sense a position in a three-dimensional coordinate system of at least the base portion; and
a processing unit coupled to the at least one remote non-contact position sensor, wherein the processing unit is disposed external to the stabilization unit and wirelessly transmits motion commands to the motion-generating mechanism within the base portion of the stabilization unit to move the implement portion relative to the base portion to dynamically cancel the user'"'"'s unintentional muscle movements.

Abstract
A system and method for stabilizing unintentional muscle movements are disclosed. In a first aspect, a non-contact sensing system comprises a stabilization unit, at least one non-contact position sensor coupled to the stabilization unit, and a processing unit coupled to the at least one non-contact position sensor, wherein the processing unit transmits motion commands to the stabilization unit to cancel unintentional muscle movements. In a second aspect, the method comprises a processing unit of a non-contact sensing system receiving position data of a stabilization unit that is detected by at least one non-contact position sensor and filtering the position data to identify the unintentional muscle movements. The method includes modeling the position data to create a system model and determining motor commands based upon the system model to cancel the unintentional muscle movements.
