Abstract: A PV array (10) comprising multiple PV modules (11, 12) that each have a first and second pairs of spaced apart terminals (28, 40), with the first pair of spaced apart terminals (28) being in electrical connection with the PV cells of the PV modules (11, 12). A by-pass conductor (30) connects the second pair of spaced apart terminals (40) and enables current to pass through the PV modules (11, 12) between the second pair of spaced apart terminals (40). The second pair of terminals (40) of a first PV module (11) are each connected electrically to a terminal (28) of the first pair of terminals (28) of two adjacent PV modules to which the first PV module is connected. The by-pass conductor (30) of the first PV module facilitates travel of electrical current from the first PV module to a second PV module, by connection of the first terminals (28) of the first PV module (11) to the second terminals (40) of the second PV module (12).

Abstract: Disclosed are non-linear transmission lines using ferromagnetic materials to generate ferromagnetic resonance oscillations. In one aspect, a non-linear transmission line apparatus is disclosed. The apparatus includes an outer conductor having a first side and a second internally facing side, and an inner conductor positioned internal to the non-linear transmission line apparatus. The apparatus further includes a ferromagnetic material surrounding the inner conductor, wherein the ferromagnetic material comprises nanoparticles of an ?-polymorph of iron oxide expressed as ?—Fe2O3. The apparatus also includes a first dielectric material positioned between the outer conductor and the inner conductor, the dielectric material in contact with both the ferromagnetic material and with the second internally facing side of the outer conductor, wherein the outer conductor, the inner conductor, the dielectric material and the ferromagnetic material form the nonlinear transmission line.

Abstract: A basketball practice device is for use with a basketball rim having a diameter. The practice device includes an annular body, the body having a diameter substantially lesser than the rim diameter, and at least one and preferably a plurality of supports. Each support is connected with the annular body and has a mount disposeable upon a portion of the rim. At least one and preferably a plurality of retainers each have a first end connected with the support, a second end releasably connected with the support, and a central section. Each central section is extendable at least partially about the rim portion such that the rim portion is retained between the support mount and the retainer to connect the practice device with the rim. Further, each retainer includes a generally elastic loop providing the ends and central portion and is extendable to engage with and disengage from the support.

Abstract: An anti-segregation device (10) for preventing segregation of paving material (P) that is applied to a road bed (7) by a paving vehicle (1). The anti-segregation device (10) includes a first end (14) that is connected with the frame (2of the paving vehicle (1) and an opposing end (16) proximal to the road bed (7). The anti-segregation device (10) is configured to substantially contain paving material (P) between the anti-segregation device (10) and a screed (3) on the paving vehicle (1). The anti-segregation device (10) substantially prevents larger material particles from falling, rolling or otherwise moving forwardly from the remainder of the paving material head (H) so as to generally prevent material segregation.

Abstract: A pavement temperature monitoring system (10) is used on paver vehicle (12) that is capable of forming a pavement material mat (11) upon abase surface (13), as paver vehicle (12) travels generally in a single direction. A temperature sensor (14) can be either a thermal imager, a thermal scanner, or a thermal imager operating in line “scan” mode. The temperature sensor (14) is mounted on a rear end (12a) of the paver vehicle (12) in such a way that the entire width of the formed mat can be scanned or imaged. A display device (16) is capable of receiving a plurality of electrical signals from the thermal scanner generating and displaying a graphical image (17) of the formed mat temperature profile.

Abstract: The screed assembly includes a screed plate and a screed frame. The screed plate includes a notch and the screed frame includes a tab that is inserted into the notch on the screed frame such that only screed plates and screed frames which include proper mating notches and tabs may be assembled together on road paving machines. In a preferred form of the invention, the width of the tab is approximately equal to the width of the notch to prevent lateral movement of the screed plate with respect to the screed frame when the screed plate is subjected to lateral impacts and forces during operation of the road paving machine.

Abstract: An apparatus that tamps paving material and distributes the paving material evenly across a screed plate before the paving material is leveled by the screed plate. The apparatus includes a tamper bar for compacting material, a drive connected to the tamper bar, and a biasing member. The drive intermittently forces the tamper bar downward into contact with the paving material at a desired speed and to a desired depth. The biasing member is connected to the tamper bar and biases the tamper bar upward against the drive such that the biasing member raises the tamper bar out of contact with the paving surface after the drive forces the tamper bar downward.

Abstract: A swing conveyor assembly for use with a base vehicle including a first material conveyor having a discharge location. The swing conveyor assembly comprises a platform supported by a wheel assembly, a linkage assembly adapted to be interconnected between the platform and the base vehicle and a second material conveyor. The linkage assembly is configured to permit free vertical movement over a given range of the platform and wheel assembly relative to the base vehicle. The second material conveyor has a receiving location and is rotatably connected to the platform about a vertical rotation axis. The rotation axis extends through the receiving location and the discharge location when the platform is connected to the base vehicle such that receiving location remains aligned with the discharge location as the second material conveyor is rotated relative to the first material conveyor.
