Described here are embodiments of processes and systems for the continuous manufacturing of implantable continuous analyte sensors. In some embodiments, a method is provided for sequentially advancing an elongated conductive body through a plurality of stations, each configured to treat the elongated conductive body. In some of these embodiments, one or more of the stations is configured to coat the elongated conductive body using a meniscus coating process, whereby a solution formed of a polymer and a solvent is prepared, the solution is continuously circulated to provide a meniscus on a top portion of a vessel holding the solution, and the elongated conductive body is advanced through the meniscus. The method may also comprise the step of removing excess coating material from the elongated conductive body by advancing the elongated conductive body through a die orifice. For example, a provided elongated conductive body 510 is advanced through a pre-coating treatment station 520, through a coating station 530, through a thickness control station 540, through a drying or curing station 550, through a thickness measurement station 560, and through a post-coating treatment station 570.

In an apparatus for continuously manufacturing microspheres, a dispersed phase (O) is supplied to a chamber 27 for the dispersed phase inside of a bulkhead member 26 via a supply port 23. Thereafter, the dispersed phase enters into a gap 31 between a plate 22 via a supply port 29 in a base 25. The dispersed phase which enters into the gap 31 grows microspheres (particles) having a certain diameter while passing through a microchannel 33 by pressure applied by, for example, a pump, and is mixed with a continuous phase (W), so that microspheres are produced. The thus-produced microspheres float or are suspended in the continuous phase without needing any particular external force in response to their specific gravity, allowing the microspheres to be generated and withdrawn from a withdrawal port 32 at a significantly reduced pressure in comparison to conventional methods and apparatus.

A bar code (10) has primary information (46, 48, 50, 51) encoded in one direction (e.g., horizontally) and secondary information (13, 21, 36) encoded in another direction (e.g., vertically) in single (11) or multiple tracks (35) in selected ones of the vertical bars (11) of a bar code (10). Using a non-linear, variable amplitude scanner, all of the bars are scanned in the one direction to obtain all of the primary information and all of those vertical bars having secondary information are scanned in the other direction to obtain all of the secondary information. The one direction which is perpendicular to the vertical bars (11), is determined by first rotating the scan path axis (86, 87) until both start (46) and end (48) code bars are read thereby placing the scan path entirely within the total bar code, and, then, further rotating the scan path (88, 89) to determine the direction of the minimum crossing width (Lsc 80) of the total bar code (10). Secondary information is scanned in planes orthogonal to the one direction after those vertical bars (11) having such information are first identified and selected. In a preferred embodiment, the decoded secondary information may be used to control selected station process operations for selected products in a continuous manufacturing assembly line.
