Abstract: Methods and apparatus are described that provide an alternative to dust protection shrouds that must be clamped or be otherwise affixed to the body of a tool. The shroud captures and facilitates the removal of dust from an area being worked upon by a tool bit while being attached to the bit (not the tool itself). The shroud housing includes an exhaust orifice; a shaft receptive orifice through which the bit shaft may be passed and be coupled to the tool; and means, such as a ball bearing located on the edge of the shaft receptive orifice, for attaching the shroud housing to the shaft upon which it rides as the bit rotates. The tool independent dust protection methods and apparatus taught by the invention provide a one size fits all dust shroud that does not sacrifice build quality or structural integrity in favor of flexibility.

Abstract: A patient positioning device used to position a patient during a navigated medical procedure includes a contoured patient support and a portion of a navigation system. The contoured patient support positions the patient in a desired manner. The portion of the navigation system is integrated within the patient support, such that the navigated medical procedure may be performed in a substantially unobstructed manner.
