A fluidic assay system assembly comprising: a disposable fluidic cartridge comprising at least one reaction chamber connected to a network of fluidic channels with at least one inlet channel and one outlet channel. The first wrench includes a shaft and two sockets each formed at an end of the shaft. The hardware-implemented control circuit includes a control circuit for establishing an extended refresh period of the dynamic memory based at least in part on a monitored result that indicates an occurrence of a memory loss in the dynamic memory. The combustion bowl has a center point on the z-axis and has a two-dimensional partial cross-sectional configuration defined by a peripheral line connecting coordinate points in the x-y-z coordinate space. One can generate a useful non-specular or \u201canti-interference\u201d surface in a number of ways in accordance with this disclosure, including by adding a coating of optically diffuse material, such as UV cured acrylate, to the sensor substrate, etching or otherwise roughening the surface of the sensor substrate, or applying a grating structure to the surface. First word lines and second word lines are formed on a substrate, wherein the first word lines and the second word lines are arranged periodically and extend in a first direction.
