  • Publication number: 20120188377
    Abstract: Methods and apparatus provide for a Cart Inspector to create a suspicion level for a transaction when a video image of the transaction portrays an item(s) left in a shopping cart. Specifically, the Cart Inspector obtains video data associated with a time(s) of interest. The video data originates from a video camera that monitors a transaction area. The Cart Inspector analyzes the video data with respect to target image(s) associated with a transaction in the transaction area during the time(s) of interest. The Cart Inspector creates an indication of a suspicion level for the transaction based on analysis of the target image(s). Creation of a high suspicion level for the transaction indicates that the transaction's corresponding video images most likely portray occurrences where the purchase price of an item transported through the transaction area was not included in the total amount paid by the customer.

  • Publication number: 20120173474
    Abstract: A method and system is provided for predicting at a current time “t”, a time that may be taken to travel between plurality of locations, at a future time-point “t+?”. The method includes determining deterministic component “?t+?” and predicting random fluctuation component “y1t+?”, of the time that may be taken to travel between the plurality of locations at the future time-point “t+?”. The deterministic component “?t+?” and the random fluctuation component “y1t+?” are added to predict the time that may be taken to travel between the plurality of locations, at the future time-point “t+?”.

  • Publication number: 20120147822
    Abstract: The present invention relates to a system and method for proportional-fair resource allocation for multi-rate random access. The method includes receiving, by a device, data packets to be transmitted to an access point on a shared uplink channel, and determining, by the device, whether or not to contend for access to the shared uplink channel based on a probability of access. The probability of access is based on a data transmission rate between the device and the access point.

  • Patent number: 8132725
    Abstract: A system detects a transaction outcome by obtaining video data associated with a transaction area and analyzing the video data to obtain at least one video transaction parameter concerning transactions associated with the transaction area. The transaction area can be a video count of items indicated in the video data as detected by an automated item detection algorithm applied to the video data. The system obtains at least one expected transaction parameter concerning an expected transaction that occurs in the transaction area, such as a scan count of items scanned at a point of sale terminal. The system automatically compares the video transaction parameter(s) to the expected transaction parameter(s) to identify a transaction outcome that may indicate fraudulent activity such as sweethearting in a retail environment.

  • Patent number: 8104680
    Abstract: A system detects a transaction outcome by obtaining video data associated with a transaction area and by obtaining transaction data concerning at least one transaction that occurs at the transaction area. The system correlates the video data associated with the transaction area to the transaction data to identify specific video data captured during occurrence of that at least one transaction at the transaction area. Based a transaction classification indicated by the transaction data, the system processes the video data to identify appropriate visual indicators within the video data that correspond to the transaction classification.

  • Publication number: 20110300891
    Abstract: Disclosed is a method and apparatus for allocating a set of frequency bands to a plurality of access points. The method includes generating an interference map associated with the set of frequency bands and associated with the plurality of access points. The method includes aggregating a plurality of demands to produce an aggregate demand. Each of the plurality of demands associated with one of the plurality of access points. The method includes dynamically allocating the set of frequency bands to each of the plurality of access points based on the interference map and the aggregate demand.

  • Publication number: 20110299479
    Abstract: Disclosed is a method and apparatus for allocating a whitespace spectrum associated with a plurality of access points. The method includes reporting a signal strength associated with each of a plurality of other access points to a central controller. The method includes aggregating a plurality of demands to produce an aggregate demand. Each of the plurality of demands is associated with one of a plurality of users. The method includes reporting the aggregated demand to the central controller. The method includes associating one of the plurality of users with the access point based on a user setting or associating one of the plurality of users based on an allocation by the central controller. The allocation from the central controller is based on the signal strength and the aggregated demand. The allocation indicates a frequency band from the set of frequency bands to be allocated by the access point to the user.
