Abstract: A positioning system moves an object in two generally orthogonal directions using a rotationally adjustable bearing system that connects the object to two pairs of non-parallel rails, the bearing system permitting the object to be smoothly translated in one or two directions to a desired position in planar space. This translation is performed smoothly notwithstanding a lack of parallelism between the linear rails.

Abstract: A method for tracking product in an installation in which powdered product is processed into manufactured items is provided. The method comprises introducing the powdered product into the installation through at least one inlet, obtaining measurement data for the powdered product from at least one mass sensor positioned in the at least one inlet, and dividing the measurement data into mass units of equal size. The progression of the mass units is then tracked through the installation using measurement data from at least one other mass sensor in the installation.

Abstract: A database management engine provides a user interface that allows users to access and modify employee information in a database. The database includes entries for employees, and each database entry includes identifying information about the associated employee. A user can request to modify data within database entries, for instance in order to update information associated with an employee. Responsive to the request, the database management engine identifies liabilities associated with the database modification stemming from associated tax laws. Based on the identified tax liabilities, the engine computes the aggregate tax liability owed by the employer and/or employee. Before modifying a database entry, the engine modifies the user interface to include interface elements detailing the computed aggregate tax liability. The user explicitly can be required to confirm the database modification in view of the aggregate tax liability.
