An intercept device for flying objects made of a light-weight, packable structure made of a pliable, tear resistant material that can be expanded to a large web-like structure by means of a deployment device, into the path of a flying weapon. To capture, hold and reduce the velocity of intercepted flying objects, activatable resistance bodies are incorporated into uniformly distributed masses that are connected to the perimeter of the web like structure. Contractable sections of the web, made of cable-like structures, connected to perimeter masses, act as drawstrings upon collision with flying object. This causes closure of the web around the flying object as a result of the mass's inertia and added resistance from deployable resistance structures that place tension on drawstring structures of the web. The flying object is subsequently captured within the web, held secure and it's velocity rapidly reduced.

A fuel injector including a combustion air flow conduit, a fuel inlet and, swirlers to mix the air and fuel flowing therethrough, additionally comprising fluidic control diverters including at least one control port, such that flow of control air through said control port allows variation in the degree of flow resistance to which combustion air is subjected. For example, control air flowing through the control port may impart swirl to the combustion air flow from the inlet, thereby subjecting the combustion air flow to increased resistance. Alternatively a fluidic diverter may selectively divert the main flow to either the first or second sub-conduits, each sub-conduit subjecting combustion air to different degrees of flow resistance.

A method for controlling the movement of a marine vessel comprises steps that rotate two marine propulsion devices about their respective axes in order to increase the hydrodynamic resistance of the marine propulsion devices as they move through the water with the marine vessel. This increased resistance exerts a braking thrust on the marine vessel. Various techniques and procedures can be used to determine the absolute magnitudes of the angular magnitudes by which the marine propulsion devices are rotated.

A glazing panel system is provided with improved glazing panels, retention clips and / or U-shaped connectors. The retention clip may engage the glazing panels at locations lower than top ends of the upstanding seam flanges. In one embodiment, an internal U-shaped connector is positioned to engage the seam flanges while an external U-shaped connector covers the internal connector and the seam between adjacent glazing panels. The retention clips may be formed with an upper transverse portion that is movable relative to the base portion of the clip to accommodate panel expansion and contraction. Also, a thicker plate or portion may be provided at a top flange for the retention clip to provide increased resistance to uplift loads trying to bend the flange.

A method and apparatus for tactile cueing of aircraft controls (21) is disclosed. The apparatus of the present invention warns pilots of approaching limits on certain aircraft performance parameters. The most common warnings are for rotor speed exceeding a moving limit. The present invention uses tactile cueing through the collective stick (21). Tactile cueing means that the pilot does not need to scan the intruments to ascertain proximity to the aforementioned limits. Instead, the pilot can operate the aircraft within proper limits by touch, while maintaining situational awareness outside of the cockpit (20). The method and apparatus of the present invention provides customary friction resistance up to a limit position that is continuously updated. According to the present invention, continued motion of the collective (21) in a direction beyond that limit position results in a breakout force and an increasing resistive force.

The resistance packs are interconnected by teeth on their rims which allow the packs to be arranged in a stack. An adjustable bench and seat are provided. One alternative is a direct drive system having angularly adjustable levers. Another alternative has a fixed number of resistance packs that can be selectively activated to add resistance.

A rigid-flex PCB includes an array of rigid PCB “islands” interconnected by a flexible PCB formed into flexible connectors. The conductive and insulating layers of the flexible PCB extend into the rigid PCBs, giving the electrical connections to the rigid PCBs added resistance to breakage as the rigid-flex PCB is repeatedly stressed by bending and twisting forces. In addition, the durability of the rigid-flex PCB is enhanced by making the power and signal lines driving the rigid PCBs redundant so that a breakage of a line will not necessarily affect the operation of the rigid PCB to which it is attached. The rigid-flex PCB is particularly applicable to light pads used in phototherapy, wherein LEDs mounted on the rigid-PCBs are powered and controlled through the redundant lines in the flexible PCB.

A method for controlling fluid flow at junctions in microchannel systems. Control of fluid flow is accomplished generally by providing increased resistance to electric-field and pressure-driven flow in the form of regions of reduced effective cross-sectional area within the microchannels and proximate a channel junction. By controlling these flows in the region of a microchannel junction it is possible to eliminate sample dispersion and cross contamination and inject well-defined volumes of fluid from one channel to another.

The magnets on the back tire may also be attached to the spokes. The trainer includes magnets as well, usually of opposite polarity, and adds resistance to pedaling when the magnetic fields of the magnets interact to resist back tire revolution.

A locking fastener assembly comprising a nut and a washer. The nut and washer each have opposed load bearing surfaces which include a series of annularly extending, slightly inclined faces forming shallow undulations around each surface. The load bearing surface on the nut is generally spherically convex and the load bearing surface on the washer is generally spherically concave. The nut rotates as it is installed while the washer is prevented from rotating so that the undulating bearing surface on the nut slides over the undulating bearing surface on the washer against ever increasing resistance until the assembly is properly seated and the nut is effectively prevented from counter-rotating by interference between opposed, inclined faces. A concave clamping surface is formed on the outer end of the washer on a radially extending flange. The flange flexes when the assembly is installed and resiliently urges the washer against the nut.

An exercise machine that provides a generally consistent resistive force against a user who walks, steps, or runs away from the machine as part of a strength training exercise program. The machine is built upon a movable frame having transport wheel assemblies that allow the exercise machine to be placed on an indoor floor surface or on the ground outdoors. The frame of the device further supports three parallel spinning assemblies that together allow a length of linear strap attached to the user to run out from the machine and thereafter be retracted or rewound back into the machine. The spinning assemblies include a flywheel assembly, a spool assembly, and a spring assembly, each co-axially arranged on a spin axle extending across the frame. The spring assembly is fixed against the frame and incorporates a coil spring that tightens with the rotation of the spin axle in a first direction (allowing the linear run-out strap to extend out from the spool assembly). The coil spring in the spring assembly thereafter tends to direct the rewinding of the strap back onto the spool assembly. The coaxial flywheel assembly provides both an initial stationary inertia and a subsequent rotational inertia. The flywheel acts as a governor to balance the changing forces associated with the resistive force increasing in the spring assembly. Positioned on the spin axle between the flywheel assembly and the spring assembly is a spool assembly that allows the strap to unwind and subsequently to be wound back onto the spool. A guide strap may be provided around the spool to maintain the linear run-out strap within the spool assembly. A resistance adjustment assembly presses a brake pad against the perimeter surface of the flywheel to adjust the force required to direct rotation of the system. A weight horn bracket is provided to add additional disc weights if necessary.
