  • Publication number: 20250043327
    Abstract: The invention features devices and kits for capturing and culturing microorganisms (e.g., bacteria, fungi, or protists) and methods of using the devices and kits to detect microorganisms in environmental and other samples. The device includes a nutrient media having a flat growth area on which microorganisms can grow. Samples are collected by contacting the device with any environmental sample, e.g., rolling device on a work surface or exposing device to air, or by filtering a sample through a membrane. Microorganisms deposited on the membrane derive nutrients from the underlying media and grow into colonies that can then be detected using methods known in the art. The detected colonies can be imaged digitally or with film.

  • Patent number: 12169971
    Abstract: A system detects a transaction outcome by obtaining video data associated with a transaction area and analyzing the video data to obtain at least one video transaction parameter concerning transactions associated with the transaction area. The transaction area can be a video count of items indicated in the video data as detected by an automated item detection algorithm applied to the video data. The system obtains at least one expected transaction parameter concerning an expected transaction that occurs in the transaction area, such as a scan count of items scanned at a point of sale terminal. The system automatically compares the video transaction parameter(s) to the expected transaction parameter(s) to identify a transaction outcome that may indicate fraudulent activity such as sweethearting in a retail environment.
