  • Publication number: 20190218081
    Abstract: System, method, and apparatus for providing transport are provided. A system for providing passenger transport, comprises a plurality of motorized transport units each comprising a coupler for mechanically coupling to a passenger carrier, and a central computer system communicatively coupled to the plurality of motorized transport units. The central computer system being configured to: receive a ride request from a user, select a motorized transport unit from the plurality of motorized transport units, instruct the motorized transport unit to travel to couple to a passenger carrier associated from the user, determine a route based on user route preference, and instruct the motorized transport unit coupled to the passenger carrier to transport the user based on the route.

  • Patent number: 4446915
    Abstract: Tube circuits for heat exchangers which provide same-end inlet and outlet connections are disclosed, in which each circuit includes conduits of two types. In a preferred embodiment, the first type conduit has two tubes and is generally U-shaped, and the second type conduit has four tubes. The inlets for each conduit are disposed adjacent each other in the assembled heat exchanger, as are the outlets for the conduits. To equalize flow and pressure drop a turbulence promoting device can be disposed in the U-shaped conduit. The circuits can be used for providing same-end connections on coils previously available only in opposite end connection configurations, such as for example, three-row full-circuited and six-row double circuited coils.
