Abstract: An inventory sensor is positioned and configured to identify playing cards stored in compartments of one or more playing card receivers. The inventory sensor allows the identity of a playing card stored in the playing card receiving compartment to be checked or otherwise verified with respect to an identity of a playing card expected to be stored in the playing card receiving compartment. Anomalies may be identified and appropriate messages provides and/or actions taken, for example removing the anomalous playing card from use.

Abstract: An inventory sensor is positioned and configured to identify playing cards stored in compartments of one or more intermediary playing card receivers. The intermediary playing card receivers may be positioned in a card transport path between an input and an output receiver. The inventory sensor allows an inventory of playing cards to be performed, for example, in response to a possibly anomalous condition or in response to a user request. Playing cards may be transferred back to the intermediary playing card receiver from the output receiver before inventorying. A new randomized set of playing cards can be created at the output receiver after inventorying.

Abstract: A playing card handling system includes a pivoting pair of jaws to retrieve playing cards from a playing card receiver, for example a carousel. The rotational or angular velocity of a picker may be approximately equal to a rotational or angular velocity of a pickup roller, as the picker approaches the pickup roller.

Abstract: A playing card output receiver that is mounted for movement includes a floor that slopes downward toward a back wall, which may, for example, assist in retaining playing cards in the playing card output receiver during movement of the playing card output receiver.

Abstract: A wheeled trolley having a resilient engaging wall for retaining a standard wheeled trolley having a resilient engaging wall for retaining a standard sized bucket containing a load. The trolley includes a set of wheels to permit easy movement over a surface. The bottom of the bucket is disposed between the wheels to provide a low center of gravity to ensure stability. The bucket is retained by a resilient engaging wall such that the trolley is lifted along with the bucket for moving up and down stairs. An adapter is located on the trolley for interchangeably receiving a handle. The handle may alternatively serve as a handle, or an extension of a handle for a tool associated with the use of the trolley.
