Abstract: The determination of a unique user is discussed in response to receiving a dataset comprising multiple user identifiers (IDs). In some cases the user IDs may be of a different type. User IDs may be compared directly to determine whether they correspond to a unique user. Network transactions and attributes associated with those network transactions may be compared to determine a probability of whether two user IDs correspond to a unique user. Network transactions and attributes associated with those network transactions may also be compared to determine that two user IDs do not correspond to a unique user.

Abstract: Systems and methods for managing electronic content from multiple content providers in a dynamic environment are provided. In operation, an advertiser can plan and book an electronic advertisement campaign by providing a campaign request specifying a requested inventory slot of atoms in an inventory space and other associated data. Thereafter, a proposed campaign can be generated based on an estimated availability of the atoms and any performance criteria specified by the advertiser. Once the proposed campaign is accepted and booked, the proposed campaign can be managed along with other active campaigns. These active campaigns can be managed based on a relative priority of the campaigns and an estimated availability for the atoms in the inventory space.

Abstract: Relationships between a plurality of mobile devices are automatically determined. For each mobile device in the plurality of mobile devices, characteristics of a user of the mobile device are determined. Based on the characteristics of the users of the mobile devices, a first role of a first user of a first mobile device is determined. Based on the characteristics of the users of the mobile devices, a second role of a second user of a second mobile device is determined. Based on the first role and the second role, a relationship between the first user and the second user is determined. A determination is made that a relationship between the first mobile device and the second mobile device is equal to the relationship between the first user and the second user.

Abstract: Systems and methods are provided for automating booking and pricing of inventory atoms are provided, where each atom defines a granular traffic target in a k-dimensional booking space. In operation, a content delivery system receives a request for an inventory slot, consisting of at least some segment characteristics and a cost objective. In response to this request, the content delivery system retrieves availability for each atom in the target inventory slot from an inventory atom database. Additionally, a pricing for each atom in the request inventory slot is also obtained. Thereafter, the content delivery system will assemble a proposed inventory slot for the advertiser that includes the atoms that meet the advertiser's cost objective and the total cost for the proposed inventory slot. If accepted, the atom inventory database can be updated to reflect the new unavailability of the atoms in the proposed database.

Abstract: A cleaning composite comprising a foam layer, such as melamine foam, and an element adapted to engage a user's hand, is disclosed. The hand-engaging element may be adjustable. A second layer, attached to at least a portion of the foam layer, may also be present. When a second layer is present, the hand-engaging element, in some embodiments, may be positioned in facing relation to a surface of the second layer or a surface of the foam layer.
