Abstract: A head unit device for controlling motion of an object includes a chamber filled with a shear thickening fluid (STF) and a piston. The piston is housed within the chamber and exerts pressure against the STF from a force applied to the piston from the object. The STF is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates. The piston includes at least one piston bypass between opposite sides of the piston that controls flow of the STF between the opposite sides of the piston to selectively react with a shear threshold effect of the first range of shear rates or the second range of shear rates.

Abstract: This disclosure relates to a disposable cutting board assembly. The assembly includes a homogenous sheet of cut-resistant paper material having an inner cutting area. A plurality of peripheral outer borders and a plurality of corners extend from said inner cutting area to an endless exterior edge. The inner cutting area, said outer borders and said corners each have a top surface and a bottom surface. A coating of plastic is disposed on said top surface of said inner cutting area, said outer borders and said corners of said homogeneous sheet of paper material. The coating of plastic provides a sterile durable surface to prevent liquid absorption into said sheet of paper material and reduces cross contamination. An embossed pattern is within said inner cutting area. The embossed pattern includes plurality of embossed lines that intersect to form a plurality of repeating geometric shapes. Each of the plurality of repeating geometric shapes include at least one acute angle.

Abstract: A device (10) administers a fluid (23) from a container (12) into a human cavity or animal cavity (66). The device includes a nozzle (20) configured to be placed in external contact with tissue surrounding an orifice (58) without penetrating the orifice. The nozzle includes a discharge opening (40), through which the fluid is ejected into the cavity, a base (24) disposed opposing the discharge opening, and a side wall (26) that extends from the discharge opening towards the base and configured so that the tissue surrounding the orifice conforms to the shape of the side wall to form a leaktight seal between the tissue and the orifice. An interior conduit (30) is disposed within the side wall and configured to deliver the fluid from the container to the discharge opening.
