Patent ID: 8628086

Claim:
A shuffling device for randomizing playing cards, the device comprising: components for contacting at least one playing card within the shuffling device to initiate or suspend movement of the at least one playing card; a processor in informational connection with the shuffling device; and at least one sensor configured and positioned to detect, without reference to playing card movement or position, values of an operational parameter of one or more of the components consisting of at least one of speed of movement of, distance of movement of, time of movement of, power supplied for movement of, force applied to, and torque applied to the one or more components and to provide a signal to the processor representative of one or more values of at least one of speed of movement of, distance of movement of, time of movement of, power supplied for movement of, force applied to and torque applied to the one or more components by sensing a magnetic field characteristic of the one or more components; the processor programmed to interpret the signal to recognize a departure in the operational parameter of the one or more components from one of an acceptable value and range of acceptable values.
