Patent number: 8079422Abstract: 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.Type: GrantFiled: August 23, 2010Date of Patent: December 20, 2011Assignee: PlanetAir Turf Products, LLCInventors: David R. Maas, Scott W. Bjorge

Patent number: 8051353Abstract: A method is described for providing Hybrid Automatic Repeat Request (HARQ) transmission feedback to a higher layer protocol in a communication system. The method includes a step of detecting HARQ retransmissions in a first layer protocol. This can be used to determine a HARQ failure or an HARQ ACK after a delay of some retransmissions. A next step includes providing feedback information about the detecting step from the first layer protocol to a higher layer protocol. A next step includes instituting corrections at the higher layer protocol, in response to the information transferred from the first layer protocol. These corrections can include immediate retransmission of those bursts of a HARQ failure, or correcting timers to match the delay of eventually ACK'ed data.Type: GrantFiled: October 23, 2007Date of Patent: November 1, 2011Assignee: Motorola Mobility, Inc.Inventors: David R. Maas, Ravi M. Adatrao, Pramod Karnam, Mark J. Marsan

Patent number: 8028758Abstract: 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.Type: GrantFiled: January 12, 2010Date of Patent: October 4, 2011Assignee: PlanetAir Turf Products, LLCInventors: David R.

Publication number: 20100303022Abstract: 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.Type: ApplicationFiled: May 27, 2009Publication date: December 2, 2010Applicant: MOTOROLA, INC.Inventors: David R.

Publication number: 20100080176Abstract: 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.Type: ApplicationFiled: September 29, 2008Publication date: April 1, 2010Applicant: MOTOROLA, INC.Inventors: David R.
