Abstract: A method of detecting an inaccurate flow rate measurement by a vibratory meter is provided. The method includes flowing fluid through the vibratory meter and measuring a flow rate and a density of the fluid with the vibratory meter, and calculating a density change rate of the fluid. The method also includes determining if the measured flow rate is inaccurate based on a comparison between the measured density and a density reference, and a comparison between the density change rate and a density change rate reference.

Abstract: Systems, methods, and computer-readable storage media for a store shelving system which can use a scale, a laser tracking system, or other mechanisms for determining how much product remains on the shelf. When the amount of product remaining on the shelf is below a threshold amount, or when the shelf inventory is exhausted, the store shelving system can deploy (1) a hologram of the product, such that customers or store associates in the aisle next to the shelf see the hologram of the product in the location where the product would be if it were available; (2) a user interface which can provide information about the product; or (3) both the hologram of the product and the user interface.

Abstract: Systems for inventory monitoring are provided. An example system can include: a light source emitting a light beam; an array of semi-reflective surfaces configured to receive the emitted light beam; and a plurality of light sensors corresponding to the array of semi-reflective surfaces, the light sensors configured to receive light beams reflected from the semi-reflective surfaces. The light sensors are positioned with respect to a plurality of corresponding products of the inventory such that the reflected light beams are blocked from receiving by the light sensors when the corresponding products are located in the inventory, and the reflected light beams are received by the light sensors upon removal of the corresponding products.
