A cover for an eating utensil having a head opposite a handle. The cover has a sleeve with a closed end and an open end for receiving the head of the eating utensil. A tab extends from the open end of the sleeve. The tab may have an adhesive on an inner side for adhering the tab to a portion of the handle when the head is positioned in the sleeve.

The present invention is directed to a low latency fiber optic local area network with a network and a plurality of nodes connected through optical fibers. Each node has a plurality of bi-directional input/output interfaces. Each bi-directional input/output interface has a demultiplexer, at least one optical power coupler, a plurality of wavelength converters, and a plurality of internal optical waveguides. The internal optical waveguides extend from each wavelength converter and are for communication with the demultiplexer, the input fiber optic interface, and the optical fiber. Each optical power coupler has a fiber optic output interface for communication with other nodes, and each demultiplexer has a input fiber optic interface for communication with other nodes.

The present invention provides a vibration dampening laminate that is lightweight and has superior sound insulation and vibration dampening properties. The vibration dampening laminate comprises a constraining layer, a viscoelastic adhesive layer, a foam spacing layer and a pressure sensitive adhesive layer including a release layer. The pressure sensitive adhesive layer and release layer are contoured to fit a profile of the article being soundproofed and vibration dampened.

The design and fabrication of dielectric grating structures with high diffraction efficiency used in reflection or transmission is described. By forming a multilayer structure of alternating index dielectric materials and placing a grating structure on top of the multilayer, a diffraction grating of adjustable efficiency, and variable optical bandwidth can be obtained. Diffraction efficiency into the first order in reflection varying between 1 and 98 percent has been achieved by controlling the design of the multilayer and the depth, shape, and material comprising the grooves of the grating structure. Methods for fabricating these gratings without the use of ion etching techniques are described.
