  • Patent number: 10246275
    Abstract: The disclosure describes, in part, a system and method for improving the stacking of containers on or in a transportation unit. In some implementations, a stacking configuration may be planned that identifies containers and a position for those containers in the stacking configuration. The stacking configuration may be planned based on dimension values of the containers such that when stacked the stacking configuration remains stable. In addition, to improve the efficiency at which containers may be stacked, the disclosure describes that containers and/or the picking of items for those containers may be sequenced so that the containers, when packed and routed, arrive in a manner that allows efficient stacking.

  • Patent number: 9956784
    Abstract: A liquid ejecting apparatus includes an ejecting head through which liquid is ejected. A supply passage connects the ejecting head to a plurality of liquid storage bodies that include a first liquid storage body to be used first and a second liquid storage body to be used following the use of the first liquid storage body. A supply mechanism discharges the liquid contained in the liquid storage bodies to the supply passage. When the supply mechanism discharges the liquid contained in the first liquid storage body to the supply passage on the basis of first energy, if the amount of liquid left in the first liquid storage body is smaller than a threshold amount, the supply mechanism discharges the liquid contained in the second liquid storage body to the supply passage on the basis of second energy, which is lower than the first energy.
