Abstract: Radio frequency identification discontinuity correction is provided by calculating a phase-time slope for a Radio Frequency Identifier (RFID) signal received from an RFID tag; estimating, based on the phase-time slope, a predicted phase reading for the RFID signal at a given time; and in response to detecting a phase discontinuity based on a difference between the predicted phase reading and an actual phase reading for the given time, adjusting a calculated distance to the RFID tag. The calculated distance may indicate that the RFID tag is inside of or outside of a designated zone, and that a motion of the RFID tag indicates travel towards or away from the designated zone, which may be used to add or remove an item associated with the RFID tag to an ongoing item list.

Abstract: A method includes scanning, by a checkout station, a plurality of items and determining, by the checkout station, a total price for the plurality of items. Each item of the plurality of items is coupled to a radio frequency identification (RFID) tag that identifies that item. The method also includes detecting, by an RFID scanner of a centralized payment station, one or more of the RFID tags of the plurality of items moving within a threshold distance of the centralized payment station and retrieving, by a hardware processor of the centralized payment station and based on the detected one or more RFID tags, the total price. The method further includes processing, by the hardware processor, a payment in satisfaction of the total price.

Abstract: A method to perform server provisioning on a plurality of computer systems to generate a plurality of target virtual machines includes: obtaining configurations from a pool comprising at least one existing candidate virtual server or server image through a discovery process; performing a clustering analysis on the configurations to group the configurations into at least two groups; and for each group, selecting a configuration from among the configurations of the group as a candidate virtual machine image; determining a cost of actions required to be performed on the candidate virtual image to result in target virtual machines with a same configuration as the configurations of the group; and selecting the candidate virtual image with the lowest cost.
