    • A polarization mode separator separates the optical signal into a first polarized signal and a second differently polarized signal traveling along respective first and second paths. A first variable delay generator located along the first path is adapted to selectively provide a first propagation delay to the first polarized signal. The first variable delay generator includes at least two rotating micro-mirrors and one or more fixed mirrors constructed on a surface of a substrate. A controller is coupled to the first variable delay generator. The controller is adapted to monitor the polarization mode dispersion in the optical signal and to position the rotating micro-mirrors to direct the first polarized signal along one of the plurality of optical paths. A beam combiner combines the first and second signals to form an optical output signal substantially compensated for polarization mode dispersion.

    • An electric power lockout apparatus is provided which includes an input terminal for electrically coupling the apparatus to an electric power source and an output terminal for electrically coupling the apparatus to a device requiring electric power. The electric power lockout apparatus also has a switch that is electrically coupled between the input terminal and the output terminal. The switch is capable of assuming: (1) an open state wherein the input terminal is electrically isolated from the output terminal and (2) a closed state wherein the input terminal is electrically coupled to the output terminal. The electric power lockout apparatus further has a first lock which controls operation of the switch so that the switch cannot assume the closed state unless the first lock is unlocked at least momentarily. The electric power lockout apparatus also has a locking structure to secure the electric power lockout apparatus to the power cord of an appliance.

    • A fiber optic ribbon cable has release elements manufactured in line with the ribbon cable so as to provide access points to the optical fibers contained therein to allow for easy application of a connector in the field. A pair of adhesive tape layers is provided about the optical fibers to create a fiber optic ribbon cable. At least one release element is provided between the adhesive tape layers and the optical fibers at one or more access points along the ribbon cable to allow for subsequent connectorization of the fibers therein. When the ribbon cable needs to be equipped with a connector, the cable is cut near the midpoint of one of the access point. After the cable is cut the adhesive tape layers and the at least one release element may be easily peeled back exposing the optical fibers. A connector is then installed onto the exposed fibers. The at least one release element is removed from the tape layers and the tape is then secured to the connector with any excess tape being trimmed off.

    • Light emitting systems are disclosed. The light emitting system emits an output light that has a first color. The light emitting system includes a first electroluminescent device that emits light at a first wavelength in response to a first signal. The first wavelength is substantially independent of the first signal. The intensity of the emitted first wavelength light is substantially proportional to the first signal. The light emitting system further includes a first luminescent element that includes a second electroluminescent device and a first light converting layer. The second electroluminescent device emits light at a second wavelength in response to a second signal. The first light converting layer includes a semiconductor potential well and converts at least a portion of light at the second wavelength to light at a third wavelength that is longer than the second wavelength. The light emitting system combines light at the first wavelength with light at the third wavelength to form the output light at the first color. When one of the first and second signals changes from about 50% of a maximum rating of the signal to about 100% of the maximum rating, but the ratio of the first signal to the second signal remains substantially unchanged, the first color of the output light remains substantially unchanged.
