US Classification:

705 10, 705 28, 705 1449

Abstract:

A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating several inventory pools, where each inventory pool represents a number of impressions deliverable to different groups of users characterized by attributes. Impressions deliverable to users represented by each inventory pool may be allocated to each inventory pool. Impressions that correspond to multiple pools may be distributed between the multiple pools. The inventory pools may be stored to a database. Afterwards, and order may be received. The order may include parameters that define an audience and a number of impressions. The number of impressions in the order may be allocated from pools in the database.

US Classification:

705 10, 705 1449

Abstract:

A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating samples of representatives that represent impression inventory, where each sample represents a number of users to which impressions are deliverable. An order may be received. The order may include a number of impressions to book and target audience information. A cushion of impressions needed to guarantee delivery of the number of impressions ordered may be determined. The number of impressions ordered plus the cushion may be allocated from the samples. A contract including the target audience information, the number of impressions, and the cushion may be stored to a database.

Abstract:

A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating an inventory pool that represents a number of impressions deliverable to all users, then determining, from multiple past orders for booking impressions, a hierarchy of parameters utilized to target users and a number of impressions deliverable to users characterized by the parameters. The inventory pool may then be partitioned into multiple inventory pools according to the hierarchy, where each inventory pool represents a number of impressions deliverable to users characterized by parameters associated with the inventory pool. The hierarchy of pools may then be stored to a database.

International Classification:

G06Q 30/00

US Classification:

705 1445, 705 1452

Abstract:

An improved system and method for forecasting an inventory of online advertisement impressions by sampling in a map-reduce framework is provided. In a map-reduce framework, samples of visitor profiles may be collected and matched to targeting profiles for displaying advertisements by distributed sample mappers. Sets of samples of visitor profiles matched to the targeting profiles may be mapped and distributed to reducer servers for integrating the samples collected by sample mappers into a reduction sample set for each targeting profile. Each reducer server may aggregate a count of samples of visitor profiles matched to a targeting profile, and the sets of samples of visitor profiles matched to a targeting profile may be integrated into a reduction sample set for each targeting profile. The sample reducers may forecast a targeting profile inventory for each targeting profile and output the targeting profile inventory with a reduction sample set of visitor profiles.

International Classification:

US Classification:

75 05B

Abstract:

A method and apparatus for producing ultrafine metal powders in which a laser beam is focused on the surface of a workpiece or feedstock and moved thereacross so as to create a cavity within the workpiece through melting and vaporization that contains the metal melted to form the cavity. A subsonic pulsating blast of inert gas is directed at the cavity to atomize the molten metal, rapidly cool the resulting droplets, and transport the droplets to a collection area. The cavity formed by the laser beam is a "keyhole" of deep cavity having a depth approximately three to four times greater than its width. The focal point of the laser beam is moved across the workpiece at a rate from approximately 50 to 80 inches per minute to ensure that the molten metal remains in the cavity prior to the gas atomization. Alloy metal powders can be produced by this method of laser blast atomization providing an alloying metal at the base metal where the cavity is formed so that, upon melting of the base metal, the alloy metal will melt into solution with the molten base metal in the cavity prior to gas atomization. Additionally, nonmetallic impurities may be removed from the molten metal contained within the cavity formed by the laser beam by vaporization.
