Abstract: Magnetically mountable tray device are presented including: a mounting plate having a front planar surface and a back planar surface; a number of mounting magnets positioned along the back planar surface; a base plate having a top planar surface and a bottom planar surface; a hinge mechanically coupled along a back edge of the base plate and along the front planar surface of the mounting plate; and a support element positioned along the bottom planar surface and mechanically coupled thereto, where the support element is positioned to contact the front surface of the mounting plate when the magnetically mountable tray device is in an open position. In some embodiments, magnetically mountable tray devices further include: a closure magnet positioned along the front planar surface; and a closure tab positioned along the top planar surface.

Abstract: Fluid activated retrieval devices for retrieving an object from a fluidic medium are presented including: a hollow base having a cavity formed therein, where the hollow base includes, a port disposed along an outer surface of the hollow base, the port configured to provide passage of the fluidic medium to the cavity, a diaphragm disposed along the cavity and proximate to the port, and an anchor disposed along the cavity for securing a line; a deployable float housing removably attached with the hollow base, the deployable float housing having another cavity formed therein, where the deployable float housing includes, a buoyant chamber disposed along a distal end of the other cavity, a spool for receiving the line, the spool disposed within the second cavity and attached with the deployable float housing; and a reactant disposed in the cavities.
