| 20080250776 | Mixing Apparatus for an Exhaust After-Treatment System - A mixing apparatus mountable within a generally cylindrical passage defined by an exhaust gas conduit of an exhaust gas after-treatment system is provided. The passage includes an outer region and an inner region operable to convey an exhaust stream and a liquid stream, such as a urea stream. The mixing apparatus includes a retainer ring operable to retain the mixing apparatus within the passage. A first plurality of fins extends from the retainer ring and is operable to impart a rotational velocity component in a first direction to the exhaust stream and urea stream in the outer region of the passage. A second plurality of fins extends from the retainer ring and is operable to impart a rotational velocity component in a second direction, opposite the first direction, to the exhaust stream and urea stream in the inner region of the passage. | 10-16-2008 |
| 20090235653 | PARTICULATE MATTER FILTER ASSEMBLY WITH A FLOW DEVICE - A particulate matter (PM) filter assembly includes a PM filter that filters PM from an exhaust stream and that includes an entry face facing a first direction of flow of the exhaust stream, and a swirl element disposed in the exhaust stream and that includes a blade that directs a portion of the exhaust stream in a second direction of flow that is different than the first direction of flow. The blade directs the portion of the exhaust stream to distribute the exhaust stream over a frontal area of the entry face of the PM filter. A related method of filtering particulate matter from an exhaust stream is also provided. | 09-24-2009 |

| 20090143026 | System and Method for Adaptive Polarization Diversity Between Closely Spaced Antennas - An electronic device comprises a transceiver and a probe. The transceiver is connected to a first antenna and a second antenna. The first and second antennas are configured to one of transmit and receive radio frequency signals. The first and second antennas are configured to exhibit a polarized diversity. The probe re-establishes the polarized diversity when the polarized diversity has been disrupted. | 06-04-2009 |
| 20090146887 | Reduced Volume Antennas - A device includes (a) a first wireless communications arrangement which is capable of at least one of transmitting and receiving. In addition, the device includes (b) a first antenna coupled to the first wireless communications arrangement and (c) a second wireless communications arrangement which is capable of at least one of transmitting and receiving. Furthermore, the device includes (d) a second antenna coupled to the second wireless communications arrangement. The second antenna acts as a parasitic element for the first antenna. | 06-11-2009 |
| 20100123550 | Coaxial Antenna Connection - A device comprises an RFID transceiver disposed on a first side of a printed circuit board; an antenna disposed on a second side of the printed circuit board; and a cable passing through the printed circuit board, a first end of the cable being connected to the RFID transceiver, a second end of the cable being connected to the antenna. | 05-20-2010 |

| 20100134252 | Polarized RFID Antenna with Spatial Diversity - A system, apparatus, and techniques for interrogating a Radio Frequency Identification (RFID) tag are disclosed. The system includes an RFID reader that includes a pivotable polarized antenna for reading a reader/tag link. The antenna moves at a specific frequency over a specific distance resulting in reader/tag links being moved out of a null region of the reader. Advantageously, by pivoting the antenna, the antenna apparatus minimizes signal fading and improves signal quality from tags. | 06-03-2010 |

| 20100319051 | CONTROLLING ACCESS TO RESOURCES BY HOSTED ENTITIES - Controlling resource access by entities hosted by an execution extension environment via entity identifiers associated with the resources or with the execution extension environment. Policy sets define the access to the resources. Each policy set includes a principal identifier for execution extension environment, a resource identifier for one of the resources, and access rights. The principal identifier or the resource identifier includes one of the entity identifiers. Access requests from entities are evaluated by comparing the entity identifiers to the policy sets. In some embodiments, the policy sets implement access control for web browsers hosting executable code that attempts to access resources on a computing device. | 12-16-2010 |
| 20100323716 | CONTROLLING AD DELIVERY TO MOBILE CLIENTS - Systems and methods for controlling ad delivery to mobile clients while maintaining user privacy are herein provided. One exemplary method involves a location broker service. The method includes receiving, at an ad delivery service, a location use token from a mobile client, which may be a single use token. The method includes sending, from the ad delivery service, the location use token to the location broker service for verification at the location broker service. The method includes receiving, at the ad delivery service, the mobile client location from the location broker service based on the verification. The method includes delivering, from the ad delivery service, a location-targeted ad to the mobile client at the mobile client location, where the delivering is further based on a geographic density of a plurality of mobile clients. An advertiser using the ad delivery service may be billed based on location use token history. | 12-23-2010 |
