Abstract: An acoustic imaging system coupled to a sensing plate to define an imaging surface. The acoustic imaging system includes an array of piezoelectric acoustic transducers coupled to the sensing plate opposite the imaging surface and formed using a thin-film manufacturing process over an application-specific integrated circuit that, in turn, is configured to leverage the array of piezoelectric actuators to generate an image of an object at least partially wetting to the imaging surface.

Abstract: An outdoor hunting blind shelter which is completely portable, all weather, and compact is an inflatable single unit hunting blind and a camper's restroom facility combined, furnishing features consisting of walls and roof which are supported by hollow, tube-type ribs forming a framework all of which are made of vinyl plastic. The hollow, vinyl plastic ribs are inflated with air through an air valve located in the foundation rib. The walls and roof are of thin plastic vinyl material joined to the ribs, and they feature an opening for entry and departure in one wall of the shelter. Windows for viewing and firing firearms are provided in the other walls. Support tie-off loops are located at each corner top and bottom of the shelter for extra support if needed. Restroom facilities include both shower and tub combinations.
