An implantable connector electrically connects multi-conductor leads to an implantable medical device such as a neurostimulator. The connector is assembled directly into a hermetic feedthrough of the implantable device and utilizes the feedthrough housing as a sustaining structure for connector clamping. The receptacle contacts detachably connect proximal lead contacts to corresponding feedthrough pins, which provide pass-through connections to electronic circuitry contained in a hermetically sealed case. The receptacle contact has resilient contact tines designed to engage a corresponding lead contact in a sliding manner. The receptacle contact is integrated with a contact guard which protects the receptacle contact from inadvertent handling damage. The contact guard is substantially more rigid than the resilient contact to resist deformation. The contact guard protectively shields the receptacle contact tines and prevents unintended contact tine excursion. In one embodiment, the contact guard is pre-attached to the receptacle contact prior to joining to the feedthrough pin. In another embodiment, the contact guard is an integral part of the feedthrough pin. Numerous embodiments with contact preload are provided.

A vehicle seating arrangement can comprise a fore-facing lower seating assembly, an aft-facing lower assembly, and an upper seating assembly positioned between the fore-facing and aft-facing lower assemblies. The lower and upper assemblies can be configured to form a 3-seat unit in which a portion of a seat of said fore-facing and aft-facing lower seat assemblies underlaps a portion of an upper seating assembly. At least one of the fore-facing and aft-facing lower assemblies can be angled with respect to the upper seating assembly to shorten the overall linear dimension of the 3-seat unit and provide egress areas for lower passengers to aisle access. A vertical member can be configured to attach to the upper seating assembly and to a ceiling structure to reduce the load on the floor.

The present invention provides a system and method for actively manipulating and controlling aerodynamic or hydrodynamic flow field vortices within a fluid flow over a surface using micro-jet arrays. The system and method for actively manipulating and controlling the inception point, size and trajectory of flow field vortices within the fluid flow places micro-jet arrays on surfaces bounding the fluid flow. These micro-jet arrays are then actively manipulated to control the flow behavior of the ducted fluid flow, influence the inception point and trajectory of flow field vortices within the fluid flow, and reduce flow separation within the primary fluid flow.

The present invention provides flow field control techniques that adapt the aft body region flow field to eliminate or mitigate the development of massive separated flow field zones and associated unsteady vortical flow field structures. Embodiments of the present invention use one or more distributed arrays of flow control devices (submerged in the boundary layer) to create disturbances in the flow field that inhibit the growth of larger vortical structures and/or to energize the aft body shear layer to keep the shear layer attached the aft body surface. These undesirable aerodynamic phenomena produce increased vehicle drag which harms vehicle range, persistence, and loiter capabilities. Additionally, the unsteady nature of the turbulent vortical structures shed in the aft body wake region may produce increased dynamic buffeting and aft body heating by entraining nozzle jet exhaust (a.k.a. jet wash)—requiring additional structural support, shielding, and vehicle weight.

The preset fraction is preferably approximately 50% of the maximum possible braking effort, and may be tuneable. The preset period of time is preferably approximately one second, and also may be tuneable.
