The predefined relationship information comprises a plurality of predefined actions.

Abstract: A method, computer program product, and system to perform a sale transaction are provided. The method includes identifying each item of a plurality of items, based on at least one image of the plurality of items, determining a cost for each item, optionally identifying a person based on an image of the person, adding each of the items and each of the costs to a sale transaction, and charging the person for the sale transaction.

Abstract: Described techniques enable the tracking and reporting of resource utilization at multiple levels of granularity, the highest of which involves tracking resource usage by a particular object in aggregate. When aggregate usage for the particular object is within certain parameters, actual resource usage is not reported at the lower level of granularity, but is replaced by placeholder values. When aggregate usage for the particular object exceeds a threshold, the particular object is considered to be a “hot spot.” Resource usage for the particular object can then be reported (and tracked, if not already) at the lower level of granularity until the particular object is no longer a “hot spot.” The efficiency of the tracking may be further enhanced by leveraging a bifurcated counting mechanism in which a full count is updated only at selected sample times, with intermediate counters used to store changes in between sample times.

Abstract: Method, computer program product, and system to facilitate an audit of a checkout transaction, where the checkout transaction is associated with a virtual transaction record reflecting interactions of a person with a first set of one or more items of a plurality of items within an environment. The method includes acquiring image information including a shopping receptacle associated with the checkout transaction, and identifying a second set of one or more items of the plurality of items that are included in the shopping receptacle using the acquired image information. The method further includes comparing the first and second sets of items, and determining, based on the comparison, whether to perform an audit of the checkout transaction.

Abstract: A method, computer program product, and system are disclosed for managing a return transaction within an environment having a plurality of purchasable item. The method acquires, using at least one visual sensor disposed within the environment, first image information including a first person and including a first item associated with the first person. The method identifies the first person using image analysis performed on the first image information. Further, the method determines, using image analysis performed on the first image information and based on one or more predetermined criteria, that the first item is eligible to be returned by the first person within the return transaction. Upon completion of one or more predefined return tasks specified for the first item within the return transaction, the method updates a first data structure representing an inventory of the environment to reflect the returned first item.

Abstract: Described techniques enable resource accounting and tracking in high access rate systems using low cost memories. A first set of counters is maintained in relatively lower cost memory. The first counters generally indicate the amount of resources used for each object in a set of objects, but on a potentially delayed basis. A second set of counters of smaller size is stored in a relatively higher cost memory that supports high arrival and departure rates for accurate accounting. Each second counter indicates the amount of resources assigned (or unassigned) to an object since the object's first counter was last updated, and is incremented or decremented whenever this amount changes. A background process is configured to update individual first counters from the corresponding second counters on a recurring basis. The exact times at which a given first counter is updated may vary in accordance with a variety of approaches.

Abstract: Aspects of oversubscription monitoring are described. In one embodiment, oversubscription monitoring includes accumulating an amount of data that arrives at a network component over at least one epoch of time. Further, a core processing rate at which data can be processed by the network component is calculated. Based on the amount of data and the core processing rate, it is determined whether the network component is operating in an oversubscribed region of operation. In one embodiment, when the network component is operating in the oversubscribed region of operation, certain quality of service metrics are monitored. Using the monitored metrics, a network operation display object may be generated for identifying or troubleshooting network errors during an oversubscribed region of operation of the network component.

Abstract: To provide a user with descriptive images for each function performed by a button, the embodiments described herein use a transforming graphical expression that presents different images depending on the particular function the button is currently performing. For example, if the button is used to increase speaker volume, the graphical expression may display plus sign, but if the button is currently being used to navigate through a display menu, the graphical expression may be transformed into an arrow to indicate the direction a selection element in the menu moves if the button is activated. Thus, as the current function of the button changes, the graphical expression presented to the user also changes. In this manner, the same button may be used to perform multiple functions while presenting to a user a customized graphical expression indicating the current function of the button.

Abstract: A method, computer program product, and system for providing a security check of items being purchased by a consumer. A digital image of items for purchase arranged on a scale is captured. An estimated total weight and a cumulative center of mass of the items are estimated. An actual total weight and cumulative center of mass of the items are measured using the scale. If the estimated total weight of the items differs from the actual total weight by more than a first threshold amount and/or if the estimated cumulative center of mass of the items differs from the measured cumulative center of mass by more than a second threshold amount, an alert can be output. The alert can include an instruction for the customer or a store employee to rearrange the items on the scale to attempt to resolve the discrepancy.
