David Chung - San Francisco CA, US
Rajas Moonka - San Ramon CA, US
Gokul Rajaram - Los Altos CA, US

Assignee:

Google Inc. - Mountain View CA

International Classification:

G06Q 30/00

US Classification:

705 261, 705 1423, 705 1451, 705 1473

Abstract:

Merchants create ecommerce-enabled ad units advertising items offered by the merchants. The ad units contain functionality enabling customers to purchase the items by interacting with the ad units. The ad units have associated bid prices that the merchants agree to pay for sales through the ad units. The merchants provide the ad units to a broker. The broker publishes the ad units on web pages provided by publishers. A customer receiving a web page interacts with the ad unit to purchase the item. During the interactions, the broker dynamically updates the ad unit to carry out the transaction. The broker collects the bid price from the merchant and shares it with the publisher that published the page on which the ad unit appeared.

Abstract:

Merchants create ecommerce-enabled ad units advertising items offered by the merchants. The ad units contain functionality enabling customers to purchase the items by interacting with the ad units. The ad units have associated bid prices that the merchants agree to pay for sales through the ad units. The merchants provide the ad units to a broker. The broker publishes the ad units on web pages provided by publishers as comparison shop ad units that contain multiple ad units and functionality for navigating among them. A customer receiving a web page interacts with an ad unit to purchase the item. During the interactions, the broker dynamically updates the ad unit to conduct the transaction.

US Patent:

Filed:

Jul 11, 1991

Appl. No.:

7/728489

Inventors:

David Y. Chung - Edison NJ
Mark J. Struglinski - Bridgewater NJ

Assignee:

Exxon Chemical Patents Inc. - Linden NJ

International Classification:

C10M14302
C08F 800
C08F 2006
C08F 600

US Classification:

252 43

Abstract:

Degraded molecular weight copolymers of ethylene alpha-olefin are provided. The ethylene alpha-olefin copolymers, before degradation, are characterized by having a narrow molecular weight distribution and are comprised of intramolecularly heterogeneous and intermolecularly homogeneous copolymer chains. The degraded copolymers are useful as viscosity index improvers for oils.

Appl. No.:

5/512753

Inventors:

David H. Chung - Palo Alto CA

Assignee:

Fairchild Camera and Instrument Corporation - Mountain View CA

International Classification:

G06F 1300

US Classification:

3401725

Abstract:

A microprocessor system having at least two separate large scale integration devices. A first of the two large scale integration devices is a central processing unit formed on a single semiconductor die, and the second large scale integration device is a memory circuit formed on a separate single semiconductor die. The term "die" as used herein is conventional and refers to a unitary semiconductor body or chip. The central processing unit requires an external program counter which contains memory addresses of instruction codes to be used by the central processing unit. The memory device is electrically coupled to the central processing unit and includes a memory for storing the instruction codes, and a program counter for addressing the memory. Provision is made to incorporate additional memory circuits to expand the size and capability of the microprocessor system. System interrupt circuitry is also provided for interrupting system operation to change to a new sequence of instruction codes.
