Abstract: The present invention provides a method of producing a set of mechanically connected cells (200), especially for use in a vehicle traction battery (704). The method comprises placing successive layers of cells into a fixture, and joining each new layer to the existing layers using a layer of adhesive.

Abstract: The present invention provides a method of producing a set of mechanically connected cells (200), especially for use in a vehicle traction battery (704). The method comprises producing a plurality of rows of mechanically connected cells in a first jig, and subsequently connecting the cells together in a second jig. Advantageously, the method may substantially reduce the problem of tolerance stack associated with mechanically connected cells.

Abstract: Systems, apparatus, and methods for conducting amplification-based analyses, including PCR testing. In one illustrative embodiment, a system may include a testing container assembly and a testing unit. The testing container assembly may include a sample collection port, a sample preparation chamber, and a reaction chamber. The sample collection port may include a bottom opening sealed by a plug member. In use, the testing container assembly may be placed in a seat of the testing unit with a sample in the sample collection port, closed by a lid. A plunger may dislodge the plug member and the sample drawn into the sample preparation chamber. Once sample preparation is complete, a channel may be opened, and the prepared sample flows into the reaction chamber which is then sealed. Testing including amplification reactions, may then be performed, followed by detection, as by detecting fluorescent emissions in the reaction chamber.
