The robotic arm is connected to a rigid back brace that is strapped to the wearer to maintain posture, and is capable of boosting human weight-lifting capacity by 18kg.
In individuals with spinal cord injury, spinal deformities can result in the development of back contours that deviate from the shape of standard rigid back support shells.
The sudden loss of one foothold induces a sudden change in body attitude (Fig. 13) because the leg is not rigid (back-lash of joints, flexibility of joints induced by PD controller, etc).
In the regime dominated by misalignment, backing layer deformation can counteract misalignment giving rise to improved load sharing when compared to an identical fibrillar array with a rigid backing layer.
This paper investigates the possibility of incorporating rigid backing material into the transducer design to increase its stiffness and depth capability without adversely affecting its wide bandwidth and high transmitting levels.
The mirrors are made of a 1 mm thick aluminized plexiglass sheet, reinforced by a rigid backing consisting of a phenolic honeycomb sandwiched between two carbon fiber mats epoxy glued.
Towards the creation of an efficient sound-absorbing structure with MPPs alone, the acoustical properties of a structure composed of two parallel MPPs with an air-cavity between them and no rigid backing is studied numerically.
Errors in the bulk acoustic properties, infered from normal surface impedance data on two different thicknesses of an isotropic material against a rigid backing, are also examined in an illustrative numerical study.
The results are amenable to asymptotic analysis; in particular, solutions for stress-free or rigid back faces follow easily as limiting cases of the backing impedance, and the long-time asymptotes of stress and velocity in the target are seen to be independent of the target's elastic properties.
It reminds me that beneath their stern demeanor, their rigid backs and strict voices, they are also simply women.
The FCS Stash Premium Backpack has a top loading main compartment, a rear compartment with neoprene laptop suspension harness, easy access front organizer pocket, ergonomically designed, mega thick shoulder straps and rigid back support system, fleece lined mp3 and sunglass pocket with waterproof zipper, and a multiple accessory side stash pocket system.
