Abstract: Interfaces are provided which integrate mistake-proofing concepts in a way easily understandable by the operator and easily configured by a manufacturing engineer. As mistake-proofing concepts are developed tables are populated and associated with specific assembly processes. Sensors are employed to monitor parts selection and tool usage. Sensors used for tool use and parts selection, error messages and actions to be performed or monitored are all defined and related in the tables and in turn to specific assembly orders. The tables are also populated with logic pointers, which are referenced by a Process Logic Control (PLC) unit that has been programmed to recall and carry out infinitely variable monitoring or control of the assembly process. For example when a particular order has been identified to the PLC by way of a scanned barcode or other means, a bill of material and assembly sequence is provided to the operator by appropriate means such as a CRT monitor.

Abstract: Method and apparatus for providing a turbofan blade 40 adapted to initiate and control a boundary layer transition at a side surface of the blade 40 during operation as a component in a turbofan assembly 35. The turbofan blade 40 includes a leading edge 55, a trailing edge 58, and two side surfaces including a high-pressure side surface 49 and a low-pressure side surface 52. At least one of the two side surfaces has an essentially smooth surface portion 61 located between the leading and trailing edges, and the essentially smooth surface portion is interrupted by a surface deviation 64. The surface deviation is configured to fix a positionally unstable laminar to turbulent boundary layer transition 24 at a location toward the trailing edge from the surface deviation during operation of the turbofan blade in the turbofan assembly.

Abstract: The present invention relates to a hearing aid system comprising a hearing implant and a method of powering a hearing implant, the system comprising an external ear canal module and an implant, wherein the signalling and/or powering of the ear implant is by way of a light signal being provided to the implant through the ear drum from, for example, the ear canal module.

Abstract: A chair and desk combination has a base, a chair attached to the base and a work surface attached to the base. In one embodiment, the height of the seating surface is vertically adjustable. In another embodiment, the chair is capable of swiveling about a vertical axis. In yet another embodiment of the invention, the distance between the forward edge of the seating surface and the rearward edge of the work surface is laterally adjustable.

Abstract: A book rack and pencil tray combination has a book rack and a pencil case attached to the bottom wall of the book rack.

Abstract: A monotube suspension damper including a cylinder tube having a fluid chamber and a gas chamber, a piston dividing the fluid chamber into a compression chamber and a rebound chamber, a primary fluid flow path across the piston including flow control valves which throttle fluid flow, a secondary fluid flow path across the piston parallel to the primary flow path including flow control valves which throttle fluid flow, and a tubular connecting rod on the cylinder tube connected to the piston. A valve spool is supported on the piston for linear translation between closed and open positions blocking and unblocking the secondary flow path. A control rod inside of the connecting rod is disposed between the valve spool and a flexible diaphragm exposed to pneumatic pressure in an expansible load leveling chamber between sprung and unsprung masses of the motor vehicle.

Abstract: A damper provides tunable variable rates in both extension and compression operation. A piston is carried in a cylinder tube separating out extension and compression chambers. The piston carries a first valving assembly that is tuned to provide a first damping level when fluid flows through the piston from the extension chamber to the compression chamber and a second valving assembly that is tuned to provide a second damping level when fluid flows through the piston from the compression chamber to the extension chamber. A control valve assembly is mounted to move with the piston. When the control valve assembly is closed, fluid flow between the compression and extension chamber flows substantially only through the first and second valving assemblies and when the control valve is open at least some fluid flows between the compression and extension chambers through a secondary valve assembly without passing through the first and second valving assemblies.

Abstract: An electronic ballast control apparatus and method for fluorescent lamps includes applying a heating current through the filaments of the lamp, and delaying the application of arc current through the filaments and the gas for a predetermined time. This allows the filaments to heat up to a level capable of sustaining thermionic emission, thereby eliminating sputtering damage upon the application of the arc current.
