  • Patent number: 8197775
    Abstract: The present invention provides a detection article including at least one fluid control film layer having at least one microstructured major surface with a plurality of microchannels therein. The microchannels are configured for uninterrupted fluid flow of a fluid sample throughout the article. The film layer includes an acquisition zone for drawing the fluid sample into the plurality of microchannels at least by spontaneous fluid transport. The film layer also includes a detection zone having at least one detection element that facilitates detection of a characteristic of the fluid sample within at least one microchannel of the detection zone. The detection article may be formed from a plurality of film layers that are stacked to form a three-dimensional article.

  • Patent number: 7957575
    Abstract: The invention is directed to counting techniques for counting biological agents on a biological growth plate or similar medium. In order to automate the counting of biological agents, a biological growth plate is inserted into a biological scanning unit. Upon insertion of the biological growth plate, the biological scanning unit generates an image of the plate. Then, the amount of biological agents that appear in the image, such as a number of bacteria colonies, can be counted or otherwise determined using image processing and analysis routines performed either by the scanning unit or an external computing device, such as a desktop computer, workstation or the like. A variety of counting rules are described herein that can be used to improve the accuracy of automated counts of biological agents on a biological growth plate.

  • Patent number: 7771986
    Abstract: A system and an apparatus for use in detecting a target microorganism or agent is disclosed which involves a solid support carrying a binding partner specific for the particular microorganism or agent and the solid support being characterised in that it defines means for protecting the binding partner from being dislodged or scraped off the solid support by physical means. The provision of protection against the binding partner being dislodged from or scraped off the solid support improves the reliability of tests such as immunoassays being conducted with the solid support and also enables such tests to be automated. Modules and machines for use with the solid support, and the automated conduct of tests are also disclosed.

  • Patent number: 7496225
    Abstract: The invention is directed to a biological scanner for scanning biological growth plates. The biological growth plate is loaded into the biological scanner via motorized rollers, and an actuator presses the growth plate against a platen once the growth plate is drawn to a scanning position within the scanner. The biological scanner then generates one or more images of the growth plate. Moreover, sensors can be arranged to facilitate sensing and positioning of the growth plate in a plurality of locations for imaging different parts of the plate. Additional embodiments are directed to features such as a hinged door that facilitates access to the scanner, and footings disposed on various sides of the scanner to facilitate flip-over of the scanner for simplified use by right-handed or left-handed users.
