Abstract: A computing device, such as a surgical hub, may obtain performance data associated with a device, such as a surgical device in an operation room. Based on the performance data, a computing device may identify a performance signature associated with the surgical device. A computing device may determine whether the surgical device is an original equipment manufacturer (OEM) device or a counterfeit device. A computing device may compare the operation data and/or the performance signature to data (e.g., data from a ML trained model) associated with OEM devices. Based on the comparison, a computing device may determine whether the operation data associated with the surgical device is within a normal operation parameter. If a computing device determines that the operation data outside of the normal operation parameter, the computing device may send a message to a health care professional.

Abstract: A concentrated slurry comprises a high molecular weight polymer, a carrier, a wetting agent, and dispersant. The slurry is characterized by its ability to reduce turbulent flow and skin friction thereby reducing drag of a vessel when the slurry is mixed with water and dispersed in a thin sheet along the surface of a vessel.
