Abstract: A seating unit of a modular seating system, said seating unit comprising: a first lateral member comprising a first mounting arrangement; a second lateral member opposing said first lateral member and comprising a second mounting arrangement; a seat support member having a longitudinal support axis extending through said first lateral member and said second lateral member; and a seat articulated to said seat support member; wherein said first mounting arrangement is configured for coupling to said second mounting arrangement of a second lateral member of a neighboring identical seating unit, so as to attach said seating unit and said neighboring seating unit to each other; and wherein said seat support member has a first end associated with said first lateral member and an opposite second end associated with said second lateral member.

Abstract: A solar thermal energy system (20) includes a plurality of modules (22), which are connected end-to-end to define an extended solar trough. Each module includes a frame, having an outer edge of circular profile and an inner edge of parabolic profile, having a focus at a geometrical center of the circular profile. The frame includes first and second end segments (42) at respective first and second ends of the module, and a pair of rigid torque tubes (44) connected longitudinally between the first and second end segments. A motorized drive (46) engages and rotates the outer edge of the frame about the geometrical center. Multiple mirror segments (40) are fitted to the inner edge of the frame. At least one heat transfer tube segment (24) is held stationary at the geometrical center of the frame.

Abstract: A closure includes a panel closing against a frame. A set of abutment surfaces for supporting the panel against applied forces is completed by a displaceable abutment block which selectively assumes an engaged state disposed between an abutment surface of the panel and an abutment surface of a strike jamb. The geometry of engagement is such that forces acting on the abutment block opposing opening of the panel are primarily compressive forces. Certain implementations additionally, or alternatively, employ abutment blocks for locking along the lintel or the threshold of the opening.

Abstract: A seating system for supporting a user in a seated position employs a worn article (10), such as a tactical vest or a backpack, carried on the torso of the user (12). An anchoring system is deployed in defined spatial relation to a lower seat support (16). The anchoring system and the worn article have complementary connecting portions (20) selectively interconnectable to anchor the worn article (10) relative to the lower seat support (16) so that the lower seat support and the worn article together define a seat for supporting the user in a seated position with a region (14) of the worn article providing a back rest. The complementary connecting portions are disconnectable to allow the user to move freely with the worn article remaining on the torso of the user.
