Abstract: System and methods for dynamic replenishment in a facility are disclosed. A mobile inventory processing device reads a machine readable tag affixed to a perishable item and transmits an indication of the perishable item to a stock inventory processing device. The stock inventory processing device retrieves a stock inventory value corresponding to the perishable item and a historic daily sales value for the perishable item from a database. The stock inventory processing device determines a restocking value based on whether the historic daily sales value exceeds the stock inventory value. The stock inventory processing device transmits a second indication to the mobile inventory processing device, The second indication correspond to insufficient shelf stock of the perishable item. The mobile inventory processing device receives the second indication and outputs an auditory alert in response to the second indication.

Abstract: A molten plastic delivery system is disclosed having a nozzle defining a nozzle channel with a downstream nozzle channel opening. A valve pin is reciprocable within the nozzle channel between a closed position and an open position. The system includes a bell crank having first and second arms that are connected at and rotatable about a pivot. The first arm is coupled to the valve pin and the second arm is coupled to a push-pull cable such that angularly pushing the second arm about the pivot via the push-pull cable moves the valve pin to the open position and angularly pulling the second arm about the pivot via the push-pull cable moves the valve pin to the closed position.

Abstract: The present invention comprises a novel propulsion method and apparatus for personal air vehicles generally consisting of gyroscopic movable assembly containing a gyroscope flywheel that produces thrust. In a preferred embodiment the gyroscope is hubless. The gyroscope flywheel integrates permanent magnets along its perimeter ring while spokes with an airfoil cross-section and positive incidence angle create airflow when rotated. The spokes couple the gyroscope's perimeter ring with a smaller central hubless ring. Proximate to the gyroscope's flywheel is an electromagnet fixed assembly that produces phasing electromagnetic fields that rotate the gyroscopic movable assembly. The invention comprises a self-contained apparatus with no external motor because the assembly is a motor with a self-stabilizing gyroscope that produces directional airflow that can be used to propel air, land and sea vehicles.

Abstract: The present disclosure relates to a thin coated optical fiber that enables connector assembly without stripping the optical fiber. In particular, the thin coating comprises a hard coating, a dye concentrate, and an adhesion promoter. The formulation of the coating promotes adhesion to a glass cladding of the optical fiber and to a ferrule bore (into which the optical fiber is inserted) by not causing silane decomposition of the coating. Moreover, the coating is colored to enable, among other things, fiber identification within a connector. The thin coated optical fibers exhibit good mechanical and optical performance properties as discussed herein.
