Abstract: An agricultural input supplier can provide seed products by tying the compensation received for the seed products to an evaluation of the land base on which the seed products are to be planted and/or the performance of the seed products on the land base. The evaluation of the land base may be based on environmental classification and/or genotype-by-environment data. In addition to tying the compensation to the land quality and the seed performance, this approach to providing seed allows for recommendations to be made to the producer regarding which seed products should be used on the land base. The performance of the seed product on the land base may also be verified.

Abstract: Managing risks of crop production can be performed by understanding the relative performance of different agricultural inputs under the same or similar environmental conditions. In addition, managing of crop production risks can be performed by understanding variations in the performance of the same agricultural inputs over a range of environmental conditions. By being able to describe and understand these variations in performance, decisions can be made which are consistent with overall business and/or production objectives and limit risk associated with variations in environmental conditions. In addition to producers there are other stakeholders in the crop production process, such as financial institutions, insurance providers, users of crops produced, and input suppliers. These and other stakeholders can provide financial incentives to producers for managing crop production risks through use of environmental classification and/or genotype-by-environment information.

Abstract: Methods and software for selecting seed products or other agricultural inputs for planting within an associated land base include classifying the land base with an environmental classification, determining at least one seed product to plant within the land base based on the environmental classification, and providing an output comprising identification of the at least one seed product to plant within the land base.

Abstract: Methods and software for selecting seed products or other agricultural inputs for planting within an associated land base include dividing the field into regions, providing an environmental profile for each of regions, determining a recommendation of a seed product to plant within each of the regions based on the environmental profile and performance of the genotype of each of the seed products in the environmental profile of the regions, and providing an output identifying the seed product to plant within each of the regions.

Abstract: A low noise electronic three phase bridge controlled brushless DC motor suitable for whiteware appliance pumps and other appliance applications. Back EMF zero crossing sensing is used to determine rotor position and thus stator winding commutation times. Motor torque and speed are controlled by pulse width modulating the operation of that bridge switching device which has just been switched from an OFF state to an ON state on each new commutation. All three stator windings have current flowing in each winding commutation to improve motor current waveform and thereby reduce motor noise, but the current in one winding is always terminated before the end of the commutation period to allow the back EMF in that winding to be sensed to zero crossing.

Abstract: A spin tub of a washing machine is driven by an electronically commutated DC motor. The commutation devices are connected to a DC power supply and have free-wheeling diodes connected in parallel therewith. The washing machine includes other components having inductive windings. A controller terminates commutation of power to the motor windings. A voltage threshold detector monitors the voltage of the power supply. Switching structure connects the inductive winding of an unused component in the machine across the power supply when the detector detects that the voltage has exceeded a predetermined value and subsequently disconnects the inductive winding of the unused component from the power supply when the detector detects that the voltage has reduced below the pre-determined value.

Abstract: A washing appliance having a thermally actuated diverter valve to allow for the diversion of water through the water holding receptacle of the washing appliance, where control means controls the turning on and off of an inlet valve and energizing of the thermally actuated diverter valve. A method of controlling a thermally activated valve in the cycle of the washing appliance is also disclosed. This method provides for the operation of a thermally actuated diverter valve during a recirculation wash phase in a washing appliance. The present invention allows for the thermally actuated diverter valve's “on time” life to be conserved, particularly in situations where the flow of water into the appliance is low, for example when the appliance is used in areas where water pressure is low, or when valves or pipes are blocked or obscured.

Abstract: A disk drive has a base containing disks that are mounted on a central drive hub. A cover is mounted and sealed to the base. The cover has an aperture that is sealed with a flexible membrane. The membrane is selectively deflected into contact with the hub or one of the disks by a displacement device. The displacement device is completely external to the sealed drive to avoid contaminating the drive. In one version, a disposable plastic snap clamp is secured to the drive to lock the disks from rotation. A pusher finger on the clamp automatically engages and deflects the membrane into frictional engagement with the disk to immobilize it. The locked position is used during periods of non-operation of the drive. When the drive is operational, the clamp is removed to release the disks for rotation.

Abstract: A laundry washing machine in which a suitable level of water is automatically determined for any particular load size. The machine is operated to first determine an initial estimation of the clothes load and to then fill to a water level suitable to the initial load estimation. The machine is then operated in such a way to check if the estimated water level is actually sufficient for the clothes load, essentially by determining the resulting load on the laundry machine motor. If the water level is found to be insufficient, then more water is added before the checking routine is carried out once again. When the water level is determined to be suitable for the clothes load, washing is commenced.

Abstract: A radially and axially preloaded bearing that has a very low mass and axial profile and which can be used in a actuator pivot of a direct access storage device without the need for a second bearing to counter the preload. An outer race of the bearing is split in order to form an open ring. Three balls are placed between the outer race and an inner race. Both the inner surface of the outer race and the outer surface of the inner race are formed such that two contact points exist between each ball and each race. Alternatively, the outer race is a closed toroid. The inner race is radially split to form a lower and an upper race, each being a closed toroid. In yet another alternative, the outer race is radially split into an upper outer race and a lower outer race. The inner race is a single closed toroid. A limiter is used to limit the movement of each of the balls. Alternatively, a conventional ball cage is used.

Abstract: A laundry washing machine in which the period of each agitation stroke (comprising "ramp", "plateau" and "coast" phases) is controlled by adjusting the "coast" phase of each stroke in order to maintain consistent washing performance. The "coast" phase is initiated (after a predetermined period has elapsed in the "plateau" phase) by starting a timer and allow the motor to coast until the motor velocity drops to a predetermined reversal velocity at which point the motor is reversed to begin the next agitation stroke. The value of the timer when the velocity reaches the reversal velocity is compared to a desired value or range of values. The predetermined value of the reversal velocity is increased if the timer value is greater than the desired value or range of values. Alternately, the value of the reversal velocity is decreased if the timer value is less than the desired value or range of values. The period of the coast phase of the next agitation stroke should then be closer to the desired period.

Abstract: A laundry machine which includes a method for adaptively controlling the flow of water into the laundry machine during the rinse phases of a wash cycle. Water is admitted into the machine through a proportional valve and the flow rate with the valve set at a predetermined degree of opening is calculated. This is compared with a desired flow rate and the degree of opening of the valve is incremented, decremented or left unaltered, depending on whether the calculated flow rate is less than, greater than or substantially the same as the desired flow rate.
