US Classification:

707713, 707719, 707720, 707770

Abstract:

Various embodiments of a system and method for diminishing workload imbalance across multiple database systems are described. Embodiments may include a resource balancer configured to, for each of a multiple database systems hosting database resources assigned to different user entities, generate a system usage score for that database system based on database usage scores of respective database resources hosted by that database system. Each usage score of a given database resource may indicate a quantity of work performed by the respective database system to process one or more requests directed to that database resource. The resource balancer may also be configured to generate one or more instructions to move a database resource from a first database system having a first system usage score to a second database system having a smaller system usage score in order to diminish an imbalance of workload across the database systems.

Abstract:

Cable robots may be used to automatically load items onto one or more surfaces in any environment. An item may be received on a carrier that is connected to tensioning actuators of a cable robot by one or more cables in tension. The actuators of the robot may be manipulated in concert to move the carrier from a first position to a second position, which may be fixed or in motion, at which the item may be expelled from the carrier. The carrier may include induction wheels and/or conveyors for receiving the item thereon and for expelling the item therefrom. The cable robot may be provided in series with a conveyor and mounted to a frame, and used to load items onto a delivery vehicle, such that the frame may be withdrawn as items are loaded.
