A tile assembly having a plurality of tiles adapted to join in an interlocking and repeating fashion. A plurality of tile assemblies are joined to each other, forming a roof with a streamlined look. Each tile assembly includes left and right center tiles laterally spaced along matching edges. The tile assembly includes upper and lower tiles of the same configuration as the center tiles, fitting over and under, respectively, the center tiles. Each tile has repeating patterns laterally spaced to each other and contiguous along matching lateral extents. Each pattern consists of a generally diamond shaped main surface with vertically spaced apices and laterally spaced apices. Two upper flanges extend upwardly and outwardly each pattern's main surface, along the upper edges, joining in an upper flange apex. Two lower flanges extend downwardly and outwardly from each pattern's main surface, along the lower edges, joining in a lower flange apex.

Tile and tile assembly for a roof

A tile assembly having a plurality of tiles adapted to join in an interlocking and repeating fashion. A plurality of tile assemblies can be joined to each other to form a roof. Each tile assembly includes left and right center tiles positioned side-by-side. Each tile has a generally diamond shaped main surface with vertically spaced upper and lower apices and laterally spaced lateral apices. Two upper flanges extend upwardly and outwardly from the main surface along upper edges and are joined in an upper flange apex. Each center tile includes two lower flanges that extend downwardly and outwardly from the main surface along the lower edges. The tile assembly includes upper and lower tiles of the same configuration. The upper tile fits over the adjacent upper flanges of the two center tiles, and the lower tile fits beneath the adjacent lower flange of the two center tiles.

A coplanar waveguide biosensor and methods of use include a coplanar waveguide transmission line and a sample containment structure. The coplanar waveguide transmission line is operable to support the propagation of an electromagnetic signal and includes a signal line and one or more spaced apart ground elements. The signal line is configured to conduct a time-varying voltage, and the one or more ground elements are configured to maintain a time-invariant voltage, a detection region being formed between a portion of the signal line and a portion of at least one of the one or more ground elements. Detection methods are improved through the enhancement of the electric field in the detection region via impedance discontinuities in the signal line and ground elements. The sample containment structure intersects the detection region of the coplanar waveguide transmission line and includes a cavity configured to hold 1 ml or less of sample solution within the detection region.
