  • Publication number: 20220277236
    Abstract: The disclosed computer-implemented method may include matching transportation requests to transportation providers using a dynamic transportation matching system. Matching transportation requestors which have varying preferences for waiting times and transportation pricing with transportation providers having varying levels of available supply may involve matching methods that satisfy the transportation requestors while maintaining an appropriate level of supply. A method which provides immediate service for transportation requestors that may be willing to pay a premium fare while placing transportation requestors not willing to pay a premium fare and may be willing to wait may provide a balance of supply and demand of transportation providers. Accordingly, immediately matching transportation requestors not willing to wait while placing the transportation requestors willing to wait in a queue may provide the balanced approach to managing transportation provider availability.

  • Publication number: 20210306280
    Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for dynamically controlling requestor device queues by monitoring and utilizing the throughput rate of matched provider devices and requestor devices. In some embodiments, the disclosed systems determine throughput rate of matched provider devices and requestor devices in real-time and/or predicts throughput rate utilizing historical features of a particular location. The disclosed systems can generate and provide queue request notifications to requestor devices based on a throughput rate at the location. Specifically, the disclosed systems can monitor a current queue status over time, compare the queue status to a queue threshold, and dynamically generate queue request notifications that reflects throughput-based queue modifiers as the current queue status approaches the queue threshold.

  • Publication number: 20200281332
    Abstract: The present disclosure describes a wearable electronic device, having at least one pre-formed stress point that is readily broken when subjected to an excessive external force, thereby causing the wearable to separate, rather than transferring forces, and potential injury, to a user.

  • Publication number: 20060201120
    Abstract: An air treatment assembly for treating air passing through an air duct comprises a frame defining an interior space and having an inlet opening providing access to the interior space, an air treatment medium sized to be inserted into the interior space through the inlet opening, and a keyed connection between the frame and the air treatment medium to control the engagement of the air treatment medium with the frame. The air treatment assembly also comprises a frame defining an interior space, an air treatment medium sized to be received within the interior space, and an air quality module integrated with the frame.

  • Patent number: 4066107
    Abstract: A machine and method for filling containers with controlled volumes of chitterlings is supplied by a hopper that is loaded from its open top from a vessel filled at ground level and then elevated and dumped into the hopper. A volumetric dispenser at the bottom of the hopper employs a cut-off blade cooperating with spaced scissor end plates to separate a volume to be dispensed from the bulk quantity by scissoring off the chitterlings. Open top containers are carried beneath the dispensing end on a conveyor and then the filled containers are moved to a turn-table where they may be manually capped.
