Abstract: A method for inspecting a rail of a conveyor system includes illuminating the rail with a light beam in the form of a line of light directed obliquely to a surface of the rail. The method further includes translating the light beam along the rail in a direction of translation, the direction of translation generally perpendicular to the line of light and sensing reflection of the light beam from the surface as the light beam is translated. The method additionally includes using the reflection to create a three-dimensional topography of the surface, applying thresholds to the three-dimensional topography to detect features of potential interest in the topography, and determining physical characteristics of the features of potential interest. In addition, the method includes using the physical characteristics to identify faults in the rail associated with the features of potential interest and mapping locations of the faults.

Abstract: A tissue culture chamber is disclosed. The chamber is a casing that provides for growth of three-dimensional tissue, and more specifically for the growth of skin tissue, that can be grown, preserved in frozen form, and shipped to the end user in the same aseptic container. The tissue culture chamber includes a casing comprising a substrate within the casing designed to facilitate three-dimensional tissue growth on the surface of the substrate. The casing includes an inlet and an outlet port which assist the inflow and outflow of media. The casing also includes at least one flow distributor. In one embodiment, the flow distributor is a baffle, which is used to distribute the flow of the media within the chamber to create a continuous, uniform piece of three-dimensional tissue. In a second embodiment, the flow distributor is a combination of deflector plates, distribution channels, and a flow channel.
