Abstract: An interior space expansion system for use with a structure needing collapsible and/or expandable space, including: a base structure having an aperture therethrough; a movable structure disposed within a central region of the base structure when in a sunken position and substantially exterior the base structure when in an elevated position; and a lifting system coupled to the base structure and the movable structure. The base structure is a trailer or recreational vehicle. The movable structure includes a cab a carriage and a footing. The lifting system couples to the footing and transitions the movable structure between the sunken and elevated positions. The lifting system is not substantially disposed within the central region of the base structure when the movable structure is in the elevated position. There is a cap member for covering the aperture when the movable structure is in the sunken position.

Abstract: A device for performing target activated transfer that includes a mounting surface for mounting a tissue sample; and a light source positioned to substantially uniformly irradiate both stained and unstained regions of the tissue sample with light energy that activates the reagent to selectively adhere the stained regions to a transfer surface. Also described is an automated system for transferring tissue from a tissue sample to a transfer substrate. The system includes means for holding a tissue section that includes targets specifically stained with an absorptive stain thereby resulting in a stained tissue surface, and a flexible transfer film that includes a lower thermoplastic layer in sufficient thermal contact with the stained tissue surface; an irradiating assembly configured to provide a predetermined uniform light dose to the entire tissue section; and means for applying a constant pressure to the transfer film during irradiation.

Abstract: A method of removing a target from a biological sample which involves placing a transfer surface in contact with the biological sample, and then focally altering the transfer surface to allow selective separation of the target from the biological sample. In disclosed embodiments, the target is a cell or cellular component of a tissue section and the transfer surface is a film that can be focally altered to adhere the target to the transfer surface. Subsequent separation of the film from the tissue section selectively removes the adhered target from the tissue section. The transfer surface is activated from within the target to adhere the target to the transfer surface, for example by heating the target to adhere it to a thermoplastic transfer surface. Such in situ activation can be achieved by exposing the biological sample to an immunoreagent that specifically binds to the target (or a component of the target).
