  • Publication number: 20210094720
    Abstract: A disposable cup includes a sidewall and a plurality of first, second, and third flaps arranged along a top end of the sidewall. The flaps are bendable along respective creases in the sidewall to a stacking configuration, an open configuration, and a closed configuration. In the stacking configuration, the first, second, and third flaps extend upward from and are aligned with the sidewall, which allows for multiple cups to be nested and stacked. In the open configuration, the first, second, and third flaps are downwardly bendable to respective positions along an exterior surface of the sidewall, which allows for full access to a liquid in the cup and drawing on the surface of the liquid contained within the cup in the form of latte art. In the closed configuration, the first, second and third flaps together define a concave cover to the cup and an elevated spout for drinking the liquid.

  • Publication number: 20190077536
    Abstract: A spill resistant disposable cup is comprised of a sheet of flexible material rolled into a cylindrical or frustoconical shape sealed at its edges and with a sealed bottom. The cup has at least three tabs that can be folded down in an overlapping manner to close the top of the cup. The tabs contain an interlocking mechanism to lock folded tabs in place. Two of the tabs are spaced apart to define a gap and a drinking opening when the tabs are folded down. The tabs can be shaped to form an internal sealing edge that provides resistance from leakage and spills if the cup is tipped when full.

  • Publication number: 20170010343
    Abstract: This invention provides a system and methods for tracking the positions and behaviors of moving objects such as animals. In one embodiment, the system comprises one or more tracking unit, one or more base nodes, one or more remote data hubs, and one or more remote processor with display. Each tracking unit (e.g. attached or inserted into the tracked animals) could transmit acoustic signal with a unique signature. The base nodes, after time stamping the received signals, relate the signals to the remote processors where the signals will be processed and the 3-dimensional spatial coordinates of the tracking units, and hence the animals, can be identified. Further processing of the positional information would reflect the activities and behaviors of each animal. Additional sensors included in the tracking unit provide further information about the states of the animals such as temperature, heart rate or blood pressure etc.

  • Patent number: 8781851
    Abstract: A dynamic claims adjudication system is provided that implements a dynamic claims adjudication process to provide flexible determination of the adjudication rule set to be used to adjudicate a claim for a particular prescription drug regardless of the mandates of the formulary and the rigidity of the tier into which the drug is placed on the formulary. The claims adjudication system and corresponding methods dynamically determine the adjudication rule set to be used to adjudicate a claim based on an analysis of criteria and identification of a tier changing criteria. Accordingly, the rigidity of conventional formulary based claims adjudication is eliminated in favor of dynamic and flexible real time claims adjudication.
