摘要： A filter cartridge end-of-life mechanism and a filter cartridge assembly for a water treatment device. The end-of-life mechanism comprises a float which is moved along an escapement path each time the device is filled. A counting mechanism connected to the float provides a continuous visual indication of the amount of useful life remaining in the filter cartridge. The cartridge assembly includes a tray detachably connected to a filter cartridge. The tray is positioned beneath the outlet end of the cartridge to remove water treatment particles from the treated water.

摘要： An optical switch and attenuator in which any waveguide in an input waveguide bundle may be selectively optically aligned or misaligned with any waveguide in an output waveguide bundle. The waveguide bundles are attached to beams that translate the bundles through non-parallel arcs. The device provides high-performance switching and attenuation of any number of input and output waveguides.

摘要： A fiber optic module which includes a framework receiving circuit card cartridges. The cartridges have a plate which extends along the sides of the housing with the first edge extending a differing length than the second edge. The module includes a housing having a framework with spaces for receiving the cartridges. The framework has slots formed therein for receiving the edges of the cartridges. The slots and spaces align the cartridges in the housing so that the cartridges are properly aligned in the housing.

摘要： A patch cord includes a cable having a primary transmission member contained within a protective sheathing. An energy transmission member is carried on the cable and extends from a first end to a second end. First and second couplings are connected to the first and second ends of the energy transmission member. The first coupling receives energy from an external source and transmits the energy along the energy transmission member toward the second coupling. The second coupling receives energy from the energy transmission member and generates a visible signal in response to the received energy.

摘要： A method of construction is disclosed for an optical switch having a first and second array of optical fibers held in axial alignment and relatively rotatable about an axis of rotation to effect optical coupling and decoupling of fibers of the opposing arrays. The method provides for polishing terminal ends of fibers of the arrays. The method includes holding the array against a complimentarily shaped reference surface while polishing with a polishing medium disposed between the surface and the array.
