Abstract: An adjustable ramp apparatus installed as part of a flat surface, such as a deck, adapted for angular elevation to an inclined position for providing a ramp between the platform level and the entryway door sill level of a trailer-type home. The apparatus is elevated by means of an actuator-driven mechanical linkage located under the surface of the primary ramp platform adjacent to the trailer type home or structure. When the actuator is disengaged, the ramp returns to a lowered position so that the door to the home is not blocked. An alternative embodiment includes a secondary threshold ramp located beneath the surface of the primary ramp platform that moves into place as the apparatus is actuated to fill the gap between the door sill and the elevated primary ramp platform.

Abstract: An olfactory patch comprises a well formed by a reservoir layer, the well is sandwiched between a barrier layer and a permeable layer. The permeable layer defines a pathway for olfactory fluid flow from the well. The flow of the olfactory fluid may be commenced by an initiator mechanism. The olfactory patch may utilize any olfactory fluid or combination of fluids within the same patch. The patch may utilize olfactory fluid which provides aromas or masks odors or has deodorizing capability or the olfactory fluid may contain therapeutic or pest control agents which are released from the patch by aromatization or by direct skin absorption or by inhalation.
