According to typical inventive practice, a first metallic material is poured into a mold including a bottom inside surface having regularly arrayed rises (truncated spherical convexities). The molten first metallic material cools and solidifies to include a surface correspondingly having regularly arrayed dents (truncated spherical concavities). The resultant “inner casting” is removed from and repositioned in the mold so that the inner casting's dent-laden surface faces upward. Ceramic spheres are placed in the dents. A second metallic material (having a higher melting point than the first metallic material) is poured into the mold with the inner casting and spheres in place. The molten second metallic material cools and solidifies as an “outer casting” surrounding the inner casting and the spheres. The resultant integral armor structure includes the inner casting, the outer casting, and the spheres, each sphere embedded partially in the inner casting and partially in the outer casting.

A preparation for the transdermal delivery of a biologically active substance into the body of a patient comprises particles of a formulation comprising the active substance. The particles are irregular in size and shape and may be produced by a low cost manufacturing method such as grinding from a thin film. The particles are angular, i.e. they have sharp edges and corners that allow them to penetrate the outer layer of the skin when subjected to pressure from a roller or an array of blunt-tipped microstructures. Sucrose may be used as an excipient with the active substance to form suitably rigid and angular particles.

A personal hygiene cleansing device is disclosed which attaches to the wall of a shower or bath stall and to the water supply at a shower head in the stall. The device is adjustable to meet the height and other personal requirements of the user. Two generally vertically oriented, rubber coated bars are adjusted to a proper height and spacing for a user. When the height and the spacing between the two vertical bars is correct, pushing a users' buttocks against the vertical bars causes the cheeks of the buttocks to be spread exposing the area to a vertical fan shape water spray from a spray head that is part of the device. The rubber piping on the generally vertical bars prevent the bars from slipping along the skin of the buttocks to maintain maximum spreading of the cheeks of the buttocks. Spray water with or without soap exits the elongated spray head to cleanse or rinse the rectal or genital area.
