  • Patent number: 11974474
    Abstract: An organic light-emitting display apparatus includes an organic light-emitting diode, a driving transistor configured to control an amount of electric current flowing to the organic light-emitting diode from a power line, a compensation transistor configured to diode-connect the driving transistor in response to a voltage applied to first and second compensation gate electrodes of the compensation transistor, and a gate insulating layer between the compensation gate electrodes and a compensation active region of a compensation transistor. A layer structure of the gate insulating layer between the first compensation gate electrode and the compensation active region is different from a layer structure of the gate insulating layer between the second compensation gate electrode and the compensation active region.

  • Publication number: 20210158467
    Abstract: A computerized system for automatic delivery worker assignment. The computerized system may include at least one non-transitory storage medium comprising instructions that, when executed by the at least one processor, cause the at least one processor to perform steps. The steps may include receiving an actual number of units sold during a first time period; receiving an indication of a number of parcels received during a first period of time at a first camp; receive a unit per parcel rate associated with the first camp; generating, based on the received actual number of units, the number of parcels received, and the unit per parcel rate, a forecast calculation for the first camp; determining, based on the forecast calculation, a number of routes; receiving an indication of an available number of delivery workers; and assigning a plurality of the delivery workers to the determined routes.

  • Publication number: 20200302385
    Abstract: Methods and systems for automatic package tracking and prioritized reordering include receiving, through a network interface, information relating to an order, a first package identifier associated with a first package, and event data associated with a plurality of package identifiers that include the first package identifier, the order comprising a first group of items, where the first package is configured to hold the first group of items and is to be delivered to a first recipient within a first predetermined period of time through one or more existing routes; parsing the event data based on the first package identifier; determining whether the first package exists based on the information; and transmitting a signal to a computer system to deliver the first package or to reorder the first package based on the determinations.
