Abstract: A stand chair is operated by a pair of screw shaft-type linear actuators which extend upwardly and forwardly from a pair of spaced-apart frame members. One embodiment has a solid seat and another has a split sweat with a drop-away front portion. One or more motors are provided to operate the screw shafts in such a way as to raise the rear seat portion without changing its angular orientation in space. Connector links interconnect the frame with the front seat portion so as to cause it to drop downwardly out from under the thighs of an occupant, while the back seat portion raises upward, thereby assisting the occupant to stand up and exit the chair. Various additional features such as armrests, wheels and a reclining backrest may also be provided.

Abstract: An undergarment and undergarment changing accessory system includes an undergarment, at least one changing accessory for cleaning or treating an undergarment wearer or caregiver, and a container comprising sheet portions that are partially sealed together with releasable seals along perimeter edge portions that may be readily pulled or peeled apart to expose the undergarment (such as a diaper) and changing accessory contained therein. A fixed or non-releasable seal or fold region may optionally connect the sheet portions after the releasable seals are opened so that the sheet portions form an enlarged sheet that can be used as a sanitary changing surface. A releasable seal established along a divider portion between the sheet portions and separating the undergarment from the changing accessory maintains the undergarment and changing accessory in isolation from one another and from the environment to prevent leaks or contamination prior to opening the releasable seals.
