Abstract: A modeling system determines a physical location of a device in a store and a virtual location in a virtual model of a store that corresponds to the physical location. The modeling system determines, from the virtual model, a subset of model data based on the virtual location. The model data comprises store location data applicable to the entire store, shelf data applicable to shelves in the store, and planogram data applicable to the shelves and products associated with the shelves. The subset of model data comprises the store location data, a subset of the shelf data applicable to at least a shelf within a predefined distance of the physical location of the device, and a subset of the planogram data applicable to at least the shelf and a product associated with the shelf. The modeling system generates a presentation of a scene based on the subset of model data.

Abstract: An acoustic analyzer system is provided that includes an acoustic analyzer having a reusable glass flow cell positioned within the acoustic analyzer. A disposable card body may be inserted into the acoustic analyzer and deliver sample fluid to the glass flow cell so that acoustic-wave assisted measurements may be performed on the sample fluid. The disposable card body may also deliver wash fluid to the glass flow cell, and receive waste sample fluid and waste wash fluid from the glass flow cell to prepare the glass flow cell for subsequent sample fluids. Numerous other embodiments are provided.
