Abstract: Described herein are systems and methods for determining or quantifying tinnitus conditions within a patient, including determining if a patient has some form of tinnitus as well as categorizing or determining the severity of a tinnitus condition, if present. The described systems and methods are also useful in evaluating the efficacy a tinnitus treatment by measuring the degree of reduction of tinnitus symptoms in a patient. The described systems and methods also provide a personalized profile for each specific patient, allowing for more effective treatment options as various forms or causes of tinnitus become apparent.

Abstract: A coating system for coating a part (10), such as a turbine blade or vane, has a mask (14) positioned adjacent to a first portion (16) of the part (10) to be coated and a mechanism (30) for moving the mask (14) relative to the part (10).

Abstract: An airfoil for use in a gas turbine engine is provided, the airfoil having a hole therein. A ceramic plug is inserted in the hole so that the plug extends above a depth of a thermal barrier coating, such as a ceramic, to be placed on the airfoil. The airfoil is then coated by non-line of sight vapor deposition and the plugs are then removed.
