Benefits of technology
The patent describes a carrier for holding test sample devices as they are moved through a sample testing instrument. The carrier has slots for holding the test sample devices, and optical interrupt positioning features that are in registry with the slots. The instrument also has fixed optical interrupt sensors to detect the position of the test sample devices as they move through the instrument. The technical effect of this invention is to provide a reliable and efficient way to hold and position test sample devices during sample testing.
Problems solved by technology
'280 patent) has several limitations, in that two machines, a filler / sealer and a reader, are required to process and analyze the cards.
Furthermore, additional time and labor are required to conduct the complete analysis of the card.

Embodiment Construction
[0052]This invention relates to a carrier for holding test sample devices as they are moved through an automatic sample testing machine or instrument 10. The carrier 200 is shown by itself in FIGS. 7-15. An overview of the instrument 10 will be provided first and then the various aspects and modules of the instrument will be described in further detail in the sections below in order to better illustrate how to make and user the carrier 200 in the preferred embodiment. It will be appreciated that this description of a preferred embodiment and associated sample testing machine is made by way of illustration and not limitation and that variations from the disclosed embodiment are certainly contemplated without departure from the scope of the invention.
[0053]System Overview
[0054]An overview of a presently preferred embodiment of a compact, high throughput instrument for processing test samples will now be described in conjunction with FIGS. 1-5. The details on the construction and opera...

Abstract
A carrier for holding up to N test sample devices as they are moved through a sample testing instrument. Each of the test sample devices are held in a receiving structure such as a slot in the carrier. The carrier also includes N optical interrupt positioning features, each placed in registry with one of the receiving structures (and thereby in registry with the test sample device). The instrument includes fixed optical interrupt sensors for detecting the position of the positioning feature as the carrier is moved through the instrument. In the illustrated embodiment, the position features comprise voids formed in a rib on the lower surface of the carrier. The optical interrupt sensors are positioned below the path the carrier travels over, whereby as the carrier moves past the sensor the voids, and hence position of the test sample devices, are detected.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation of U.S. application Ser. No. 10 / 695,038 filed Oct. 28, 2003, the contents of which are incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a carrier for holding and moving test sample devices through an automated sample testing instrument. The test sample devices are used for testing biological, microbiological, chemical or other types of samples.[0004]2. Description of Related Art[0005]Biological and other types of samples can be reacted and subjected to chemical or optical analysis using various techniques, including transmittance and / or fluorescence optical analysis. The purpose of the analysis may be to identify an unknown biological agent or target in the sample, to determine the concentration of a substance in the sample, or determine whether the biological agent is susceptible to certain antibiotics, as well as the concentration of antibio...
