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 bar pin bushing assembly including a bar pin having at least one end with at least one bore to receive a fastener, the at least one bore extending through the at least one end, the bar pin having a central portion having a diameter that is greater than a width or diameter of the at least one end of the bar pin, a compressible rubber section positioned around the central portion of the bar pin, the compressible rubber section further extending around downwardly tapering surfaces adjacent the central portion of the bar pin, an outer metal shell mold bonded to the compressible rubber section, a first disc insert positioned over a first end of the outer metal shell, a second disc insert positioned over a second end of the outer metal shell, and a tubular outer metal wall positioned over the outer metal shell, the first disc insert, and the second disc insert.

Abstract: A bar pin bushing assembly for connecting components including a bar pin having at least one end with at least one bore to receive a fastener, the bar pin having a central portion having a diameter that is greater than a width or diameter of the at least one end of the bar pin, a compressible rubber section having a uniform thickness positioned around the central portion of the bar pin, the compressible rubber section further extending around downwardly tapering surfaces adjacent the central portion of the bar pin, a plurality of outer metal shells mold bonded to the compressible rubber section, wherein when the bushing assembly is inserted into a hub, the plurality of outer metal shells are configured to radially compress the compressible rubber section to provide a precompressed bushing assembly.

Abstract: Client and server transaction agent coupon database interfaces are disclosed. The server transaction agent operations include receiving a shopping list from the client transaction agent, the shopping list specifying one or more product or service items and representing a coupon query initiated by the client transaction agent, formulating a coupon database query requesting coupons associated with some or all of the items specified in the shopping list, querying a coupon database and receiving coupons in response, selecting some or all of the coupons, and sending the selected coupons to the client transaction agent as a coupon query response. The client transaction agent operations include creating the shopping list in electronic form, sending the shopping list as a coupon query to the server transaction agent acting as a coupon database interface, and receiving the selected coupons from the server transaction agent as a coupon query response.

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.
