  • Patent number: 11651276
    Abstract: A computer-implemented method for generating a group of representative model cases for a trained machine learning model may be provided. The method comprising determining an input space, determining an initial plurality of model cases, and expanding the initial plurality of model cases by stepwise modifying field values of the records representing the initial plurality of model cases resulting in an exploration set of model cases. Additionally, the method comprises obtaining a model score value for each record of the exploration set of model cases, continuing the expansion of the exploration set of model cases thereby generating a refined model case set, and selecting the records in the refined model case set based on relative record distance values and related model score values between pairs of records, thereby generating the group of representative model cases.

  • Publication number: 20230095554
    Abstract: A patient transport apparatus including a base, an intermediate frame, a support deck with a fowler section, and a deck extension assembly with a head deck section, a brace extending between a mount end and a coupling end, and a pivot coupling attached to the coupling end and supporting the head deck section. A mount operatively attached to the fowler section defines a receiver slidably supporting the brace adjacent to the mount end for movement along a brace axis. A retainer interposed between the mount and the brace selectively retains the brace in one of a plurality of extension positions and is operable between: a retained configuration to prevent movement, and a released configuration to permit movement of the brace between the extension positions. Operation changes from the retained configuration to the released configuration in response to force applied to the head deck section along the brace axis.

  • Publication number: 20230046297
    Abstract: A patient transport apparatus for transporting a patient. A seat section is pivotably coupled to a support structure about a seat axis. A front wheel is operatively attached to a front strut of the support structure, and a carrier is arranged for movement relative to the support. The carrier includes a shaft defining a wheel axis, a rear wheel supported for rotation about the wheel axis, a track having a belt, and a hub supporting the shaft and the track for concurrent pivoting movement about a hub axis defined by a upright of the support structure. The hub axis extends through a plane intersecting the seat axis, fixed relative to the upright, and defining opposing first and second sides. Movement of the carrier from a chair configuration to a stair configuration simultaneously deploys the track and moves the wheel axis from the first side to the second side.

  • Publication number: 20220275725
    Abstract: This disclosure relates to a separating a fluid having multiple phases during formation testing. For example, certain embodiments of the present disclosure relate to receiving contaminated formation fluid on a first flow line and separating a contamination (e.g., mud filtrate) from the formation fluid by diverting the relatively heavier and/or denser fluid (e.g., the mud filtrate) downward through a second flow line and diverting the relatively lighter and/or less dense fluid upward through a third flow line. In some embodiments, the third flow line is generally oriented upwards at a height that may facilitate the separation of the heavier fluid from the relatively lighter fluid based on gravity and/or pumps.

  • Publication number: 20220045750
    Abstract: A PON system comprising multiple PONs, each having a respective intelligent splitter monitor (ISM). In addition to having a passive optical splitter therein, an ISM also has several remotely powered active components configured to monitor the presence of uplink light signals on the ports of the splitter and communicate with the central office using out-of-band optical signals. These ISM functionalities enable the network operator, e.g., to automatically map PON connectivity, pairing each port on the splitter with a distinct optical network unit. The PON system further comprises an optical module connected to the multiple PONs through an optical switch in a manner that supports shared access to said module by the corresponding multiple ISMs. In an example embodiment, the optical module comprises an optical transceiver capable of communicating with the ISM transceivers and one or more lasers configured to provide high-intensity light for remotely charging the ISM batteries.
