  • Patent number: 11951052
    Abstract: A patient transfer apparatus configured to traverse stairs includes a seat assembly, a rear leg pivotably coupled to the seat assembly, a track integrated with the rear leg, and a wheel coupled to a distal end portion of the rear leg. The seat assembly includes a frame with a seat portion. The rear leg is pivotable relative to the seat portion between a transport position and a stair traversing position. In the transport position the wheel is configured to contact a floor, and in the stair traversing position the track is configured to contact the stairs.

  • Patent number: 10252401
    Abstract: A clamping and spreading device for separating layers of a substrate includes a C-clamp that is configured to fixedly couple to a substrate. A second rod is coupled to and extends from the C-clamp. The second rod is selectively extensible from the C-clamp. A first wedge is coupled to and extends bidirectionally from the second rod distal from the C-clamp. A second wedge is coupled to and extends from the C-clamp. An actuator is coupled to the C-clamp and is operationally coupled to the second rod. The first wedge and the second wedge are configured to insert into a first gap defined by two layers of the substrate. The actuator is positioned to compel the second rod to extend from the C-clamp. The first wedge is compelled distally from the second wedge to separate the two layers of the substrate.

  • Publication number: 20080201652
    Abstract: Various technologies and techniques are disclosed for viewing and managing work items. A work item management application is provided to allow a user to view and manage a plurality of work items from a single view. An interactive viewing feature is provided to allow the user to interactively view complex relationships between selected groups of work items. When the user selects all of the work items of a particular type in a work item group, the orphaned items are visually indicated. A many-to-many linker feature allows the user to create many-to-many relationships between a selected group of the work items in a single operation.
