Abstract: A process and system for self-calibration of a density profiler is disclosed. The process may include measuring a density profile of a fluid in a vessel using a plurality of sensors or a single sensor, and measuring a density profile of the fluid in the vessel using a plurality of sample ports. A density of the fluid proximate a location of at least one of the plurality of sample ports based on the sensor measured density profile may then be interpolated. A density of the fluid proximate a location of at least one of the plurality of sensors based on the sample port measured density profile may also be interpolated. Adjustment of a calibration of at least one of the plurality of sensors may then be made based on both the interpolated sample port density and the interpolated sensor density.

Abstract: Methods and systems for restocking inventory. Machine readable code associated with a product that is part of a stockroom inventory is scanned with a mobile device. Based on data in the machine readable code, the mobile device obtains data relating to the product via a wireless network and displays the data to the user. The data may include product images, details, prices, marketing promotions, regulatory or safety media, inventory rules, and other data that is retrieved from an updated database. The mobile device may also populate an order amount window with a desired amount of the product to be ordered based on known and desired inventory levels. Products may be added to an order and the order placed or saved for later submission though the mobile device based on the displayed data.
