A device for extracting an implanted elongated structure from biological tissue comprises a sheath having a plurality of lumens therein opening to the sheath distal end. First and second lumens are disposed along a wall of the sheath, and a third lumen is dimensioned to receive the elongated structure. The sheath wall having the first and second lumens disposed therein is alternately compressible and expandable responsive to a bend along a bending zone of the sheath. A first wire segment is positioned in the first lumen, and a second wire segment is positioned in the second lumen, wherein the respective proximal ends of the segments are affixed proximal to the bending zone. The respective wire segments extend distally in the respective first or second lumen a first distance beyond the distal end of the sheath when the bend compresses the wall surface generally adjacent the first and second lumens, and extend distally a second distance, less than the first distance, when the bend expands the wall surface.

An electronic lock incorporating one or more shape memory metal wire segment as its electromechanical transducer. An electronic control circuit injects electrical current into the shape memory metal wire, causing it to heat up and contract. A gate is positioned by the action of the shape memory metal wire(s) to either allow or block the movement of a locking bolt that affect locking or unlocking. Millions of operational cycles are achieved by limiting the stretching of the shape memory metal wire at low temperature to small percentages of its total length. The design lends itself to miniaturization, with commensurate reduction in power consumption, that is useful to the evolution of future electronic locks.

A mascara brush head includes bristles made from shape memory polymer (SMP) filaments or fibers. The shape memory polymer filaments are selected to exhibit a first shape during assembly of the brush, and a second shape after exposure to an external stimulus in the form of heat or other energy. The brush head is initially assembled, i.e., lengths of SMP filaments are placed between wire segments and the wire segments are then twisted about each other to form a twisted wire core. The core grips the filament lengths medially of their outer ends, usually substantially at their midpoints, so as to clamp them. The first shape can be straight to facilitate assembly of the fibers in the wire core. The second shape, after assembly in the core and after being subjected to the external stimulus, can be any bristle shape suitable for enhancing the function of the brush, e.g., kinked, wavy or coiled. The brush head may be comprised solely of SMP filaments, or may be a blend of SMP filaments and any other suitable filament (e.g., nylon, natural plant or animal fibers, etc.).

A method of launching space vehicles by towing them aloft, then twirling them around a large transport aircraft (40) at the center of a formation (AA) of other tow aircraft (28, 34) and other devices of the invention. A lengthy, semi-rigid tow pipeline (14) serves as a conduit for the transfer of fuels and oxidizers, as the tow cable, and as an energy storage device that reflexes efficiently when it is flexed. The flexing of tow pipeline (14) is caused by a parachute (22) acting in conjunction with all the aircraft making the tighest turn they are capable of doing. Tow aircraft in certain arrays (28) are joined to tow pipeline (14) by sliding trollies (26) that also host canard rotor wings for the aerodynamic support of the main tube (12). The tow trollies (26) aid the sliding tow aircraft arrays (28) in gaining mechanical advantage to accelerate the space vehicle. The space vehicle may also burn its own motors for a longer-than-usual time as it gains in angular velocity because its fuels are replenished by a pipeline that automatically increases the pressure and volume of fuel flow as the angular acceleration increases. The tow pipeline (14) features a micro-hole laminar lift foil (50) on the top surface of the wing and on the bottom. By balancing the vacuum level in the plurality of chamber underneath the plurality of lift foil 50, the pilot or autopilot has an effective way to control the flight characteristics of the tow pipeline (14). In some embodiments the micro-hole laminar lift foil (50) on the top and bottom will made of transparent hollow wire segments or other material so arranged as to pass ambient light through to photo-voltaic cells below that convert sunlight to electrical energy.

A helmet has shell with a front opening covered by a faceguard of elongated wire segments. Loopstraps engage around wire segments at sides and a crown of the shell and fasteners connect the loopstraps to the shell. The fasteners each have a nut extending from an inside of the helmet shell out into a hole of the shell and an aperture of the loopstrap, and a stud removably connected to the nut by pushing and turning the stud by about a quarter turn to lock the stud to the nut. A tension spring between a head of the stud and the loopstrap urges the stud away from the nut when the stud is rotated to unlock the stud for facilitating a quick removal of the stud from the nut and a quick disconnection of the loopstrap and faceguard from the helmet shell.
