Publication number: 20150120453Abstract: One embodiment of the present invention provides a system for delivering an offer to a mobile device associated with a potential customer. During operation, the system receives data indicating that a potential customer is at or entering a targeted area or is on a vehicle associated with one or more businesses providing offers. The system then determines, with the received data, whether the potential customer has a moment of receptivity, wherein the moment of receptivity is a period of time during which the potential customer is likely to be receptive to receiving an offer. Responsive to determining that the potential customer has a moment of receptivity for receiving an offer, the system selects an offer from one or more available offers, and sends the selected offer to the potential customer.Type: ApplicationFiled: October 25, 2013Publication date: April 30, 2015Inventors: Lawrence C. Lee, Oliver Brdiczka, Francisco E. Torres, Chris Holmes, James D. Glasnapp, Michael C. Nash, Andrew J. Perelson

Publication number: 20150104800Abstract: A method for authenticating a textile material that is initiated by selecting a unique nucleic acid marker having a specific length and a specific sequence. A media that causes the unique nucleic acid marker to adhere to a fibrous material is then selected. The method then proceeds to generate a nucleic acid marker mixture by mixing the media with the nucleic acid marker. The nucleic acid marker mixture is then applied to the fibrous material. A marked fibrous material is produced by marking the fibrous material with the nucleic acid marker. The textile material is manufactured with the marked fibrous material. The textile material is then authenticated by detecting the unique nucleic acid marker with primers that are specific to the unique nucleic acid. In an alternative embodiment, the media is used as a topical treatment for the fibrous material.Type: ApplicationFiled: October 17, 2014Publication date: April 16, 2015Applicant: APDN (B.V.I.)

Patent number: 6070661Abstract: A production pump for lifting subterranean fluids to the surface of the earth. The production pump is formed from a housing having a pumping unit disposed within the housing. The housing further has a first end defining a first chamber that provides a fluid intake for the pump unit. The housing further has a second end defining a second chamber that provides a fluid outlet for the pump unit. Additionally, the pump includes a conduit that extends from the second end of the housing into the first chamber to provide fluid to the first chamber.Type: GrantFiled: November 12, 1998Date of Patent: June 6, 2000Assignee: Camco International, Inc.Inventors: Steven C.

Patent number: 6017456Abstract: A fluid separation system is disclosed for installation within a wellbore that penetrates a production formation and a discharge formation. The system comprises a first pump and a second pump each operatively connected to a means for operation, such as a downhole electric motor, and a fluid separator for separating wellbore fluids from the production formation into a first stream and a lighter second stream. Wellbore fluids are introduced into the first pump, and are then conveyed to an inlet of the fluid separator. The second stream exiting the fluid separator is conveyed to an inlet of the second pump, and from the second pump to the earth's surface. Devices are included, such as wellbore packers, to isolate the discharge formation from the production formation, so that the second stream exiting the fluid separator directly enters the discharge formation.Type: GrantFiled: October 30, 1997Date of Patent: January 25, 2000Assignee: Camco International, Inc.Inventors: Steven C.

Patent number: 4727223Abstract: An electrical penetrator employs metal-sheathed insulated conductors that extend completely through and are sealed within a tubular housing. A filler block is disposed centrally within the housing and is surrounded by elastomeric material of a sealing member. Plugs are inserted into opposite ends of the housing so as to compress the elastomeric material and are sealed within the housing. Hollow end caps threaded into the opposite ends of the housing urge the plugs toward the elastomeric material. The metal-sheathed conductors extend through the hollow end caps and through longitudinal passages in the plugs and the sealing member. The conductors are sealed in the sealing member by the elastomeric material, are sealed in the plugs by tube fitting assemblies threaded into the plugs about the conductors, and are sealed in the hollow end caps by potting material.Type: GrantFiled: June 16, 1987Date of Patent: February 23, 1988Assignee: TRW Inc.Inventors: Lawrence C.

Patent number: 4481020Abstract: A centrifugal liquid-gas separator apparatus which is particularly adapted for use downhole with a submergible pump comprises an elongated hub having disposed on its periphery helical blades defining a screw-type inducer for pressurizing a liquid-gas fluid mixture entering the apparatus, axially extending vanes defining a centrifugal separator for separating the liquid and gas components of the fluid mixture, and smoothly curved blade segments disposed intermediate the blades and the vanes for providing a smooth transition for the fluid mixture flowing from the inducer to the centrifugal separator. The apparatus is capable of maintaining a substantially constant flow rate over a large range of volumetric ratios of gas to liquid.Type: GrantFiled: June 10, 1982Date of Patent: November 6, 1984Assignee: TRW Inc.Inventors: Lawrence C.
