Abstract: The present invention relates to a three-dimensional system, and compositions obtained therefrom, wherein individual layers of the system comprise channels divided longitudinally into two compartments by a centrally positioned membrane, and wherein each compartment can comprise a different cell type.

Abstract: The present invention relates to methods for the design and fabrication of biological constructs, such as organ simulants or organ replacements, which contain complex microfluidic architecture. Designs of the present invention provide increased space in the lateral dimension, enabling a large number of small channels for small vessels.

Abstract: The foldable automobile window shade generally includes a first plurality of substantially rigid, planar elements joined together by hinges such that they form a first accordion fold portion of the shade. The shade also includes a second plurality of rigid, planar elements forming a second accordion fold portion of the shade. The shade also includes a hinge that links the first and second accordion fold portions. The hinge may be a pop-out tab in one of the elements forming the first accordion fold portion which cooperates with a through passage in one of the elements forming the second accordion fold portion. In another embodiment, the hinge may be a clip having depending and upstanding U-shaped legs that grip the elements in either the horizontal expansion mode or the vertical expansion mode.

Abstract: The foldable automobile window shade generally includes a first plurality of substantially rigid, planar elements, joined together by hinges such that they form a first accordion fold portion of the shade, a second plurality of rigid, planar elements forming a second accordion fold portion of the shade. The shade also includes a hinge that links the first and second accordion fold portions. The single hinge links end elements of the first and second accordion fold portions. In a horizontal expansion mode, the first and second end elements have planar surfaces that are adjacent to each other and the first and second accordion fold portions extend outboard from either side of the adjacent end elements. In a vertically expandable mode, the end elements are co-planar with respect to each other. The first and second accordion fold portions are disposed above the respective first and second end elements and therefore the shade can be vertically expandable as desired to cover the interior of the automobile window.
