| 20090008108 | AERATION DEVICE - A soil aeration device may include a plurality of arcuate blades mounted to an assembly adapted to rotate and translate the blades proximate a ground surface, thereby forming aeration pockets in the soil. In certain embodiments, the arcuate tines penetrate and fracture the soil while minimizing the amount of soil lifted from the pocket deposited on the top of the soil. In various embodiments, a planetary gear assembly imparts to the tine a translational and rotational movement which creates a fractured pocket in the soil while minimizing the amount of soil lifted from the pocket and deposited on the surface of the soil. In still other embodiments, the arcuate tine may have mounted thereon a coring tube that cuts and removes a plug from the pocket formed in the soil. | 01-08-2009 |
| 20090038814 | Soil Aerator - A soil aeration apparatus may include aeration tines that are actuated by a relatively compact gear system that reduces the size and weight of the apparatus. In addition, a soil aeration apparatus may operate without a centrally disposed support shaft, thus enabling the tine-holder shafts to be positioned closer to one another and reducing the size of the apparatus. | 02-12-2009 |

| 20110011602 | Soil Aerator Assembly - In certain embodiments a soil aerator may include a hinged frame assembly that cooperates with one or more weight transferring systems adapted to permit an aeration subassembly to lift off the ground when an aeration tine impacts a hard obstacle such as a rock in the soil. The weight transferring systems may in the preferred embodiments be calibrated so that only minimal upward force, such as that caused by impact of an aeration tine with a rock, may cause the aeration subassembly to lift thereby significantly reducing or preventing damage to the aeration tines and drive assemblies and substantially prolonging the life of the aerator. | 01-20-2011 |

| 20090141677 | TECHNIQUES FOR HANDLING SERVICE FLOWS IN WIRELESS COMMUNICATION SYSTEMS - A technique for handling service flows in a wireless communication system includes receiving a first packet over a first service flow. In this case, the first service flow has a first quality of service. Next, a packet classifier associated with the first packet is determined. A second service flow with a selected quality of service is then created when the packet classifier for the first packet corresponds to a selected classifier. | 06-04-2009 |
| 20100080176 | METHOD AND APPARATUS FOR SCHEDULING DOWNLINK TRANSMISSIONS IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING COMMUNICATION SYSTEM - A communication system performs adaptive scheduling by considering present and past reported CQI values and other indications of channel conditions in scheduling a Modulation and Coding Scheme (MCS) and then executing a ‘dithering’ function in order to effectuate an MCS that is intermediate between adjacent discrete MCSs. In one embodiment, the communication system determines a first MCS based on a channel quality metric received from a mobile station (MS) and then transmits data utilizing the first MCS. The communication system assigns weights to each of the first MCS and a second MCS based on whether the transmitted data is acknowledged and, based on the assigned weights, selects one of the first and second MCSs for a subsequent transmission of data to the MS. The communication system also may assign weights to each of a first and second MCS based on a transition between a MIMO-A and a MIMO-B transmission scheme. | 04-01-2010 |
| 20100214995 | COMMUNICATING SYSTEM INFORMATION IN A WIRELESS COMMUNICATION NETWORK - An apparatus and method for communicating system information in a wireless communication network. A first step | 08-26-2010 |
| 20100303022 | METHOD AND APPARATUS FOR UPLINK SCHEDULING IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING COMMUNICATION SYSTEM - A method and scheduler are provided that optimize utilization of an uplink (UL) data packet field of an UL sub-frame. In one embodiment, a request for an allocation of bandwidth is received from each of multiple mobile stations. The requests include requests for a bandwidth allocation of a first size range and requests for a bandwidth allocation of a second size range, wherein each request of the second size range requests more bandwidth than any request of the first size range. Bandwidth is allocated in a UL data packet field to the requests in order of priority, and when the allocated bandwidth does not fill the UL data packet field and a request of the second size range remains unallocated, an allocation of bandwidth to an unallocated request of the second size range is substituted for an allocation of bandwidth to a request of the first size range. | 12-02-2010 |
