An elongate electrode carrier member for implantation in a location external to the cochlear canals to position at least one, and likely many, electrodes sufficiently proximate to the organ of Corti to effectively deliver stimulation signals to the auditory nerve fibers of the cochlear. Generally, the carrier member is dimensioned to be implanted in a crevice, channel or pocket formed between the spiral ligament and bony capsule of the cochlear. Embodiments of the carrier member preferably have a minimized volume to accommodate insertion into such a crevice. In addition, embodiments of the carrier member comprise an elongate bulbous central region having electrodes disposed on the medial surface thereof, and elongate tapered side regions laterally extending from the central region. The side regions have rounded edges and are preferably flexible, while the carrier is configured to coil or turn toward the medial surface. This construction facilitates implantation of the carrier member: the carrier member has sufficient longitudinal strength to maintain its form and direction while being pushed into the surgically-formed crevice, and coils in a longitudinal plane to follow the contour of the cochlear, while the side regions serve to guide the direction of travel, flexing out of the lateral plane as necessary to avoid damaging anatomical structures. Once implanted, embodiments of the carrier member are urged to remain in its implanted position due to one or more of either the side regions extending into the corners of the crevice, and/or due to the curved lateral surface of the carrier member which approximates the curvature of the endosteum along the basal turn of the cochlea.

The invention provides a sight line based finite time convergence active defense guidance control method, relates to a guidance control method, in particular to an active defense guidance control method, and aims at solving the problem that a defensive missile is limited in overload capacity. The sight line based finite time convergence active defense guidance control method comprises the steps of firstly modeling relative motions of a target, the defensive missile and an intercept missile, adopting a sight line guidance mode to design a guidance rule for the defensive missile, then adopting a nonsingular terminal sliding mode to control the designed guidance rule, respectively defining sliding mode variables (shown in the description) of a longitudinal plane and a lateral plane, performing derivation on the sliding mode variables, substituting relative motion equations of the target, the defensive missile and the intercept missile into the variables and obtaining the guidance rule (shown in the description) of the longitudinal plane and the guidance rule (shown in the description) of the lateral plane through compilation, and controlling the missiles according to the guidance rules. By means of the sight line based finite time convergence active defense guidance control method, overload needed by the defensive missile can be effectively reduced. The sight line based finite time convergence active defense guidance control method is suitable for active defense guidance control.

The fluidtight zip fastener comprises a pair of fluidtight zip fastener carrying tapes carrying the zip fastener coupling member rows and which are in each case formed by a base tape with a soft, synthetic rubber or similar covering layer. They engage on one another by their edge portions. The pair of continuous coupling member rows is sewn to the zip fastener carrying tapes in a spaced offset position transversely to the longitudinal edges of said carrying tapes in such a way that the press-contact edge portions of the soft covering layers are in contact with one another along a longitudinal plane, which intersects the zip fastener at a central axis thereof and runs at right angles to the zip fastener principal plane. The press-contact edge portions project over said longitudinal plane, when the coupling member rows are disengaged. The edge portions, when the coupling member rows are engaged, are bent away from the side carrying the coupling member rows so as to extend roughly at right angles to the zip fastener principal plane. The soft covering layers of the press-contact edge portions engage on one another under pressure action when the zip fastener is closed and thus ensure the fluidtightness condition.

The invention discloses a guidance and control integrated design method considering all-strapdown seeker view field constraint, and aims at solving the technical problem that an existing guidance and control integrated design method is poor in practicability. According to the technical scheme, the guidance and control integrated design method comprises the steps that a missile longitudinal channel attitude control system model, a longitudinal plane missile-target relative motion model and an all-strapdown seeker longitudinal channel sight decoupling model are built; the state variable and the system output variable are selected, and a guidance and control integrated state space mathematical model considering view field angle constraint is built; a control method combining an obstacle Lyapunov function, an expansion state observer and dynamic surface control is adopted. The control method combining the obstacle Lyapunov function, the expansion state observer and dynamic surface control is adopted, and meanwhile the guidance precision and the all-strapdown seeker view field angle constraint conditions are met, so that it is guaranteed that the body sight angle detected by an all-strapdown seeker in the missile guidance and control process meets the seeker view field constraint.

An internal arrangement of aircraft fuselage walls supports two longitudinal auxiliary passage ducts at the upper part of the fuselage and on each side of its longitudinal plane of symmetry. The arrangement includes a longitudinal central element forming a dome connecting the structural ducts, an interior ceiling panel situated under the dome and facing toward the cabin, and two lateral cover panels. A lower edge of each lateral panel is articulated with respect to the fuselage so that it may occupy a raised position in which it is connected to a respective one of the structural ducts near an upper edge of the structural duct and a lowered position in which it is distant from the structural duct. Also, the upper edge of each lateral panel is extended, in the raised position, beyond the structural duct to cover the corresponding longitudinal edges of the dome and the ceiling panel.

A toy flying aircraft has a fuselage defining a central vertical longitudinal plane, with an upper front portion and a lower rear portion. The upper front and lower rear portions are coupled by a vertical support angling forward and upward from a front upper side of the rear portion to a lower rear side of the front portion. The aircraft has an at least generally circular and horizontally planar wing intersecting the front portion of the fuselage. A forward half of the wing defines an upper horizontal plane generally perpendicular to the central vertical longitudinal plane, and a rear half of the wing is downwardly offset from the upper horizontal plane to define a lift surface. A generally V-shaped planar rear stabilizer is bisected and supported by the rear portion of the fuselage so as to be located vertically entirely below the wing.

A method and apparatus for the conditioning and homogenization of glass melts that are transported in flow channels with a vertical central longitudinal plane and side walls, by using the effect of alternating cross-section changes in the flow direction and stirrers with vertical stirrer shafts installed in the flow direction. The glass melt is transported through at least one flow channel, in which cross-section changes on both sides are created by several consecutive protrusions installed in the flow direction. The protrusions are directed towards the central longitudinal plane and on their upstream sides and downstream sides have wall areas that are arranged at such an angle to the central longitudinal plane, that no right-angled or acute-angled corners are created in the flow channel. The stirrers are installed between consecutive downstream sides and the upstream sides of the protrusions.
