Abstract: A full-automatic microorganism detecting enrichment system and the enrichment method thereof are provided. A transmission apparatus is controlled by a industrial control computer to transmit a to-be-detected sample placed on a preset operating position, a culture medium comprising culture, a pipeline filter specially for collecting bacteria and a filter head sequentially into a sterilization cabin, an middle package removing cabin, an inner package removing cabin, an enrichment operating cabin, a buffer cabin and a positive bacteria filling cabin to perform corresponding operations and enrich the microorganism in the to-be-detected samples. Said system can achieve a fully automated enrichment of the microorganism in the to-be-detected samples, needs no manual operation, and saves time and labor force. Further, it can avoid false positive or false negative result caused by an effect of human factor, and achieve sterile and automatic operation with an accurate detection result.

Abstract: A luminescent solar concentrator comprises a primary waveguide and at least one photovoltaic cell. The primary waveguide has a curved surface which concentrates light on a perimeter. The photovoltaic cell is oriented at the perimeter so that it can both receive the concentrated light and receive direct light as well. A back sheet may be provided that provides structural support and protection. The perimeter may have the shape of a polygon where a photovoltaic cell is oriented along each edge. Modules and arrays of such units are also disclosed.
