Abstract

Provided herein are medical testing devices, systems, and methods that integrate multiplex, multi-technology, multi-configuration, multisample, or multi-threading capabilities. These capabilities are achieved using one or more of a level operations and communications architecture, a protocol execution engine, and a machine vision and processing system, method, or device in order to make testing of biologic or other samples more efficient in terms of cost, time, energy, or by prioritizing at least one other objective.

2. The system of claim 1 further comprising a collection station configured to collect information from at least one station, and wherein the controller maintains or modifies said schedule based on the efficiency of said schedule, anticipated availability of said plurality of stations, and said information collected by said collection station.

3. The system of claim 1 wherein said station is selected from the group consisting of:

sample preparation station, assay station, detection station, incubation station, and sample handling station.

4. The system of claim 1 wherein at least one station is a centrifuge or a thermal block.

5. The system of claim 1 wherein said schedule is based on a plurality of said subtasks being performed in a predetermined sequence or relative timing of said subtasks.

6. The system of claim 1 wherein said schedule generated by said controller provides reduces the total time required to perform the plurality of subtasks as compared to the total time required by alternative schedules.

7. The system of claim 1 wherein said cartridge receives a sample collection unit configured to accept a sample that has a volume of 250 μ

L or less.

8. The system of claim 1, further comprising a detection station, wherein said detection station is configured to collect information regarding the status of an individual biological or chemical assay and utilizing said information effective to maintain or modify the schedule of subtasks.

9. The system of claim 1, wherein said controller generates a schedule for said plurality of subtasks performed by said plurality of stations using a flexible scheduling algorithm to generate an ordered schedule of subtasks for the plurality of stations of the one or more devices such that when the subtasks are performed by the one or more devices, the input processes are completed in a manner more efficiently than if the input processes were performed sequentially by the plurality of stations.

10. The system of claim 8, wherein said controller generates a schedule for said plurality of subtasks performed by said plurality of stations using a flexible scheduling algorithm to generate an ordered schedule of subtasks for the plurality of stations of the one or more devices such that when the subtasks are performed by the one or more devices, the input processes are completed in a manner more efficiently than if the input processes were performed sequentially by the plurality of stations.

11. The system of claim 1, comprising a first station and a second station, wherein said first station is configured to perform a subtask that cannot be performed by said second station.

12. The system of claim 8, comprising a first station and a second station, wherein said first station is configured to perform a subtask that cannot be performed by said second station.
