Abstract: Systems and methods are provided for implementing a multi-persona launcher for a computing device. After a user has authenticated himself or herself to the computing device, embodiments of the present disclosure provide the user with the ability to launch applications under a variety of personas. For example, a mobile handset can detect a “dwell” event for a particular icon and can then display an option to launch the application associated with the icon under a variety of personas. The user can select to launch the application under either persona without having to log in again.

Abstract: An apparatus for measuring the displacement of visco-elastoplastic media below a surface thereof comprises an upper plate mounted such that a displacement force exerted on the top surface thereof will move the upper plate a displacement distance downward toward a base. Guides maintain the upper plate and the base in alignment such that movement is along a displacement axis. A calibrated bias element exerts a calibrated bias force resisting movement of the upper plate toward the base. A displacement measuring device measures the displacement distance, and is operative to generate a movement signal corresponding to the displacement distance. A data acquisition system is operative to receive and record the movement signal, and calculate the displacement force exerted on the top surface of the upper plate required to move the upper plate the displacement distance against the calibrated bias force.

Abstract: The present invention provides a method of maintaining fan airflow at 100% for throttle transients from 100% military power to 30% thereof by increasing exhaust nozzle area as the fuel flow the engine decreases until the exhaust nozzle reaches its fully open position. Subsequent reductions in fuel flow produce a commensurate reduction fan airflow.

Abstract: An assembly is provided for sealingly anchoring a sheet-like base roofing material on a building structure. The assembly includes an anchoring flange or plate having a number of openings therethrough, and a marshal strip of sheet martial overlies the anchoring flange and is bonded directly to the base roofing material through the openings, and preferably at a location interior of the anchoring flange. The assembly an be used in roof edge installations, for example, and can also include a fascia or a gutter arrangement, or a wide variety of other conjurations to suit a given application.

Abstract: An roof edge assembly for anchoring foam-type roofing materials includes an anchoring flange having a longitudinal channel extending along the edge of the roof, into which a floating retainer member is received and allowed to move to accommodate thermal expansion of the roofing material. At least part of the free-floating retainer member becomes embedded into the foam-type roofing material during its application after the anchoring and retainer members have been installed on the roof. The retainer member is prevented from pulling away during application of the foam. The flange member can be separate or integral with a fascia portion.

Abstract: An assembly is provided for sealingly anchoring a sheet-like base roofing material on a building structure. The assembly includes an anchoring flange or plate having a number of openings therethrough, and a marginal strip of sheet material overlies the anchoring flange and is bonded directly to the base roofing material through the openings, and preferably at a location interior of the anchoring flange. The assembly can be used in roof edge installations, for example, and can also include a fascia or a gutter arrangement, or a wide variety of other configurations to suit a given application.

Abstract: An apparatus and method for retrofitting a paper towel dispenser by the insertion of a retrofit in the dispenser. The retrofit is mounted to the dispenser so as to reduce the dispensing orifice of the dispenser and thus prevents the user from extracting more than one towel at a time. The waste and expenditure associated with the dispenser is thereby significantly reduced.

Abstract: A secondary control for a gas turbine engine powering fighter class of aircraft serves to modify the primary control solely during transient engine operation primarily in the combat box of between approximately 0.4 to 1.2 Mach number at an altitude between 10,000 to 30,000 feet of the flight envelope and does maintain higher compressor rpm, turbine inlet temperature, and engine air flow at the idle or part power thrust settings by concomitantly adjusting fuel flow and engine exhaust nozzle area thereby enhancing thrust response, low cycle fatigue life, and engine stability.

Abstract: A simple, strong and fast acting tool retention subsystem is intended for both original equipment and retrofit applications in machining centers with automatic tool changer systems. A machining center incorporating the invention is described. The invention is compatible with ANSI standards for spindles, tapered tool shanks and knobs, and is configured to eliminate the tool chatter and tool shank taper unseating and release commonly occurring in conventional spring actuated tool retention subsystems when spiral fluted cutters are used. The tool shank is positively jam locked by a rotary bolt actuator means that generates a very high value of axial pre-load tension, comparable to that which was furnished by the very successful historic manual draw-in bolt retention subsystem used in milling machines. A bi-directional free wheeling impact motor drives the rotary bolt actuator means between open and closed positions of a maximally strong collet.

Abstract: The present invention pertains to an apparatus to improve the efficiency and performance of an aerodynamic lift structure for use on sailing devices. A two-sided, spaced apart sail structure is provided with resiliently deformable struts for each side, attached at one end to a beam, fixed to the mast of the sailing device, the mast being rotatable about its vertical axis in either direction relative to vertical planes along the longitudinal axes of the sailing device and the boom in a manner whereby a cam action is produced by the beam to deform or bend the struts in a manner so as to vary the camber of the wing sail, the amount of camber of one side of the wing sail being greater than the concave curvature of the opposed side thus producing an airfoil configuration.
