Abstract: The animal-repelling device may include a base, a pop-up figure, a linear actuator, a tension spring, and an electronics unit. The animal-repelling device may be adapted to discourage deer from eating vegetation or used as a holiday decoration. The base may be placed on the ground with the pop-up figure initially in a horizontal orientation. Upon detecting motion, the electronics unit may energize the linear actuator to move the pop-up figure to a vertical orientation, light a plurality of LED lights, and play an audible sound through a sound transducer located in the pop-up figure. The tension spring may cause the pop-up figure to shake. The electronics unit may energize the linear actuator to return the pop-up figure to the horizontal orientation. As non-limiting examples, the vegetation may comprise landscape foliage, garden plants, crops, or any combination thereof.

Abstract: A method and assembly for utilizing open-cell cellular solid material in a component separation unit to separate one or more process streams into component process streams having desired compositions. A method and assembly for using said open-cell cellular solid material to separate process streams into desired component process streams in a component separation unit, wherein the open-cell cellular solid material can include oxides, carbides, nitrides, borides, ceramics, metals, polymers, and chemical vapor deposition materials.
