Method and apparatus for container storage and container retrieval

Apparatus for use in a storage and retrieval system for product held in containers is provided. The apparatus includes multiple, parallel spaced-apart support members (41) defining a plurality of rows (20), each adapted to support a base of a plurality of containers thereby forming a container store. One or more conveying means (44) is engageable with containers in a row (20) to transport the containers longitudinally within that row, the conveying means (44) movable transverse and below the rows. One or more loading means (45) is movable transverse to the rows (20) along an end of the rows to enable loading of one or more containers into a selected row. A computer control system automatically controls operation of the loading means and conveying means. The loading means (45) may include a transfer conveyor (49) extending beneath at least a portion of said rows and moveable transverse to said rows below said rows. Product may be stored in a bulk storage zone (27) in which containers of product are stored in frames (50), an intermediate storage zone (40) and a low storage zone (65). A first automated retrieval system retrieves selected stacks of containers from the intermediate storage zone (40), and a second automated retrieval system retrieves individual containers, partial stacks or stacks of containers from the low storage zone (65). Product orders are collated at a collation zone (34) and a conveying means (19) is in communication with each zone for delivering product between zones. Methods of storage and retrieval are also claimed.

Methods and Algorithms For Cell Enumeration in a Low-Cost Cytometer

The enumeration of cells in fluids by flow cytometry is widely used across many disciplines such as assessment of leukocyte subsets in different bodily fluids or of bacterial contamination in environmental samples, food products and bodily fluids. For many applications the cost, size and complexity of the instruments prevents wider use, for example, CD4 analysis in HIV monitoring in resource-poor countries. The novel device, methods and algorithms disclosed herein largely overcome these limitations. Briefly, all cells in a biological sample are fluorescently labeled, but only the target cells are also magnetically labeled. In addition, non-magnetically labeled cells are imaged for viability in a modified slide configuration. The labeled sample, in a chamber or cuvet, is placed between two wedge-shaped magnets to selectively move the magnetically labeled cells to the observation surface of the cuvet. An LED illuminates the cells and a CCD camera captures the images of the fluorescent light emitted by the target cells. Image analysis performed with a novel algorithm provides a count of the cells on the surface that can be related to the target cell concentration of the original sample. The compact cytometer system provides a rugged, affordable and easy-to-use technique, which can be used in remote locations.
