Abstract: In an aircraft, bi-stable power drive units (PDUs) move and secure cargo within an aircraft cargo hold. Such a PDU includes a frame, by which the PDU is rigidly attached to the cargo hold floor; a body pivotably attached, via a hinge, at a first end of the frame at least one drive roller attached at a second end of the body; and an actuator attached to the body and which causes a pivoting angular movement of the body, relative to the frame, about the hinge.

Operation of the robot assembly is managed by a control system. The testing system may also include a computer program that operably connects the control system of the robot assembly to a point-of-sale (POS) system, thus further automating the testing protocol.

Abstract: A waveguide including a folded, coated reflector highly reflective of radiation having two different wavelengths over a wide range of incidence angles, including grazing incidence angles. The waveguide can be employed for guiding laser radiation useful for medical or other applications, such as a combined HeNe and CO.sub.2 laser beam. In some embodiments, the invention is a hollow waveguide formed by folding a flat, coated substrate into a polygonal shape. Because the coated substrate is folded, rather than rolled into a cylindrical tube, the bending stress on the coating is concentrated at the corners of the polygonal waveguide rather than distributed over the waveguide's entire surface. Although the coating may crack at the corners of the waveguide's polygonal cross-section, the flat surfaces between the waveguide edges will be intact, and the cracks in the corners will have an insignificant effect on waveguide performance.

Abstract: A dichroic optical filter including a substrate that is substantially transparent to visible radiation, and an oxide semiconductor layer on the substrate for reflecting an infrared wavelength (such as an infrared treatment beam wavelength). An example of a suitable oxide semiconductor for reflecting a treatment beam from a CO.sub.2 layer is indium tin oxide. Preferably, the filter includes a specially designed multilayer coating on the oxide semiconductor layer to enhance the reflection of infrared and longer wavelength radiation. This multilayer coating includes alternating quarter-wave layers of high and low refractive index materials, each having an optical thickness substantially equal to a quarter-wavelength of infrared radiation to be reflected.

Abstract: A wedge mirror is disclosed for suppressing the high gain wavelengths in a laser. The mirror is provided with a pair of opposed surfaces lying in nonparallel planes. Each of the surfaces is provided with a wavelength selective coating. The coating on the surface of the mirror facing the gain medium is highly reflective of the high gain wavelength and highly transmissive of the low gain wavelength. This surface is oriented so that the light from the high gain wavelength is reflected out of the cavity. The outer surface of the mirror is highly transmissive of the high gain wavelength and highly reflective of the low gain wavelength. The combination of the wavelength selective coatings and the wedge configuration allows the high gain wavelength to be suppressed while the low gain wavelength oscillates. The subject mirror is particularly suited for suppressing the 1.06 and 1.33 micron wavelengths in Nd:YAG while allowing the 1.44 micron wavelength to lase.
