  • Publication number: 20230261481
    Abstract: A cell balancing system for balancing a set of series-connected cells, the cell balancing system comprising first balancer circuitry and second balancer circuitry. The first balancer circuitry comprises a first set of capacitors and a first switch network. The first switch network is controllable such that in operation of the cell balancing system: during a first phase of operation of the first balancer circuitry, a capacitor of the first set of capacitors is coupled to a first cell of the set of series-connected cells; and during a second phase of operation of the first balancer circuitry, the capacitor of the first set of capacitors is coupled to a second cell of the set of series-connected cells. The second balancer circuitry comprises a second set of capacitors and a second switch network.

  • Patent number: 10832351
    Abstract: A sensing system bias is reduced across a first agricultural machine and a second agricultural machine. A collection of agronomic data is accessed, that is indicative of an estimated crop yield. The collection that is accessed, for example, includes at least a first set of data sensed by the first agricultural machine and a second set of data sensed by the second agricultural machine. In addition, the first and second sets of data can be scaled based on a yield correction factor. A bias between the scaled first set of data and the scaled second set of data is determined, and a smoothing operation is performed on the scaled first and second sets of data.

  • Patent number: 10691668
    Abstract: Machine-generated data is divided into its metadata (or contextual data) that is indicative of a data container, and the data values themselves that are indicative of sensed variables. The metadata is checked to obtain a container integrity indicator of whether the data is accurate based on characteristics of the data container. The actual data values are subjected to quality checking to determine whether they have been corrupted by inaccuracies. Data corresponding to inaccurate metadata or inaccurate data values themselves is quarantined, and correction logic attempts to correct any inaccurate data. Corrected data is output with the verified data.

  • Patent number: 9508234
    Abstract: A system and method for identifying tie down restraint locations in a cargo compartment or other storage area is disclosed. The system includes labeling or otherwise highlighting the tie down locations on a floor where the cargo is to be secured. The labeling is based on a reference coordinate system that is associated with a tie down plan. Additionally or alternatively, a tie down locator device is mounted above the floor that highlights or otherwise illuminates a tie down location. As a cargo handler completes a connection, the device highlights the next tie down location.

  • Publication number: 20040127876
    Abstract: A disposable absorbent garment of this invention comprises an absorbent chassis having a front waist region, a back waist region and a crotch region extending longitudinally therebetween. A support panel extends longitudinally from one of the waist regions of the absorbent chassis and may be positioned in a folded-down condition in which the support panel overlaps the one waist region on the outside of the absorbent chassis. The support panel is elastically stretchable in a direction generally transverse to a longitudinal axis of the absorbent chassis. A fastening system is provided for securing the support panel in a chassis supporting position in which it is in its folded-down condition and elastically stretched girthwise around opposite hips of a person wearing the garment to support the absorbent chassis on the person.

    Abstract: An absorbent article is provided having a chassis with a front waist region, a back waist region, and a crotch region extending longitudinally between the front and back waist regions. An absorbent body structure extends longitudinally generally from the front waist region to the back waist region. Longitudinally extending leak guards are provided having a free laterally inward side and a laterally outward side attached to the chassis laterally outward of the absorbent body structure so as to define respective containment pockets along opposite lateral sides of the absorbent body structure. The leak guards are substantially elastomeric in a transverse direction along their longitudinal length.

  • Patent number: 5509915
    Abstract: Generally stated, the present invention provides a distinctive absorbent article comprising a backsheet layer, and a topsheet layer which is disposed in facing relation with the backsheet layer. An absorbent body is interposed between the backsheet layer and topsheet layer. The absorbent body includes a retention portion which comprises a matrix of substantially hydrophilic fibers having a distribution of high-absorbency particulate material therein. The hydrophilic fibers and high-absorbency particles can be provided in a fiber-to-particle weight ratio within the range of about 70:30 to about 30:70. A surge management layer, comprising bicomponent fibers having a denier of not more than about 3 d, is located adjacent at least one major, facing surface of the topsheet layer, and can cooperate with the article components to provide for a liquid Penetration Rate index of not less than about 2.67 ml/sec.

  • Patent number: 5156902
    Abstract: An apparatus for forming a zoned distribution of particulate material within a fibrous web includes a conveying mechanism for providing a gas entrained supply of the particulate material and a segregating mechanism for centrifugally directing at least a portion of the particulate material into an accumulation region of the apparatus. A transferring mechanism selectively directs particulate material from the accumulation region into a delivery gas stream to provide an intermittent flow volume of a selected quantity of particulate material from the accumulation region through a delivery conduit and into a web forming chamber. A fiberizing mechanism provides a flow of a selected fibrous material into the web forming chamber, and a directing mechanism controls the intermittent flow of particulate material from the delivery conduit into the forming chamber.
