Abstract: A turbine engine for an aircraft is disclosed. The turbine includes a turbine generator which is not connected to the low or high pressure spools of the turbine engine. The generator is used to create power for use in electrical systems in the aircraft. In some embodiments, the free-turbine airfoils receive the core air through an array of variable-pitch vanes. The pitch of these vanes is alterable to control the core air so that the speed of the free turbine remains substantially constant even though engine speed fluctuates.

Abstract: A transfer device for adhering a transferable material to a target substrate is disclosed. The transfer device includes a supply of transfer substrate. The transfer substrate has a carrying surface and an adhesive-type transferable material provided on the carrying surface. A pressure applicator member has an engaging surface with a release characteristic and is positioned in pressure applying relation adjacent the carrying surface of the transfer substrate. The target substrate may be passed between the transfer substrate and the pressure applicator member so that the adhesive is transferred to the target substrate. The transfer device also includes a take-up roll for winding up spent portions of the transfer substrate from which the transferable material has been transferred to the target substrate.

Abstract: A vibrotactile transducer provides a point-like vibrational stimulus to the body of a user in response to an electrical input. The apparatus includes a housing held in contact with the skin and a moving mechanical contactor protruding through in an opening in said housing and preloaded into skin. The contactor is attached to a torroidal moving magnet assembly suspended by springs in a magnetic circuit assembly consisting of a housing containing a pair of electrical coils. The mass of the magnet/contactor assembly and the compliance of the spring are chosen so that the electromechanical resonance of the motional masses, when loaded by a typical skin site on the human body, are in a frequency band where the human body is most sensitive to vibrational stimuli.
