Abstract: A sample preparation blister pack can include a plurality of reservoirs formed as blisters. The reservoirs can have an actuatable barrier layer and a seal barrier layer with contents of the reservoirs between the actuatable barrier layer and the seal barrier layer. The contents can be to facilitate isolating a biological component from a biological sample. The individual reservoirs can be adapted to release the contents through the seal barrier layer upon actuation of the actuatable barrier layer. The blister pack can have a width and a length and the reservoirs can be lined up along the length. In this example, a first reservoir contains an inert mechanical fluid and a second reservoir contains a reagent, a buffer, or a combination thereof.

Abstract: A refrigerant hose has an innermost tube defining a lumen therein, and the innermost tube is based on one of a hydrogenated nitrile butadiene rubber (HNBR), an HNBR containing polymer blend, or a copolymer thereof, which is cured with a phenol-formaldehyde resin. The refrigerant hose may further include an optional permeation inhibiting layer which surrounds the innermost tube when incorporated, a reinforcing layer disposed outwardly from the innermost tube and the optional permeation inhibiting layer when this layer is used, and a cover layer disposed outwardly from the reinforcing layer. The innermost tube has a volume swell percentage of 10% or less when exposed to polyolester oil or polyalkylene glycol oil for 168 hrs @ 125° C. Additionally, the innermost tube is devoid of peroxide and may further be devoid added elemental sulfur, sulfur donors and/or additives containing sulfur within their molecular structures.

Abstract: Embodiments described herein are directed to an adaptive AI model for 3D object detection using synthetic training data. For example, an ML model is trained to detect certain items of interest based on a training set that is synthetically generated in real time during the training process. The training set comprises a plurality of images depicting containers that are virtually packed with items of interest. Each image of the training set is a composite of an image comprising a container that is packed with items of non-interest and an image comprising an item of interest scanned in isolation. A plurality of such images is generated during any given training iteration of the ML model. Once trained, the ML model is configured to detect items of interest in actual containers and output a classification indicative of a likelihood that a container comprises an item of interest.
