An attenuating filter provides a prescribed attenuation of the intensity of transmitted, short-wavelength, ultraviolet light, in particular, at wavelengths below 200 nm, that is governed by a predefinable spatial distribution of its spectral transmittance. The filter has a transparent substrate (3), e.g. fabricated from crystalline calcium fluoride. A filter coating (5) fabricated from a dielectric material that absorbs over a predefined wavelength range is applied to at least one surface (4) of the substrate. In the case of operating wavelengths of about 193 nm, the filter coating consists largely of tantalum pentoxide. Filters of the type, which may be inexpensively fabricated with high yields, are noted for their high abilities to withstand laser radiation and may be effectively antireflection coated employing simply designed antireflection coatings.

A method of assembling a gaming device including providing a cabinet including a first side wall and an opposing second side wall and removably connecting a first side panel including a decorative layer to the first side wall of the cabinet. The method includes removably connecting a second side panel including a decorative layer to the second side wall of the cabinet. The method includes securing the first side panel to the first side wall from inside of the cabinet and securing the second side panel to the second side wall from inside of said cabinet, where the first and second panels can only be unsecured from the first and second side walls, respectively, from inside of the cabinet. The method includes movably connecting a lockable door to the cabinet, where the lockable door is movable to allow access to the inside of said cabinet.

A spring loaded spacer for fastening components and control units together with touch control face plates or panels wherein the spacer has a shank portion nested in a barrel portion, one end of the barrel portion being connected to a chassis or the like and its shank portion being connected to one or more printed circuit boards and / or components, and wherein the shank portion is spring loaded within the barrel portion and is adapted to receive one or more printed circuit boards and / or components under tensioned engagement.

The present invention describes microbicidal hydrophilic polyurethane foams endowed with polyhexamethylenebiguanide (PHMB) and / or its hydrochloride and also a superabsorbent, wound contact materials obtainable therefrom and processes for producing the therapeutically endowed polyurethane foams and the wound contact materials obtainable therefrom.

A logging while drilling tool includes a directional resistivity antenna and an antenna shield having. The shield has at least one slot having at least one electrically open end formed therein. The antenna shield may include a base portion and a plurality of spaced apart fingers extending away from the base portion such that the finger ends are electrically isolated from the tool body and from one another. The antenna shield may alternatively include a plurality of spaced apart plates that are electrically isolated from the tool body and from one another. These antenna shields have been found to provide suitable physical protection for sensitive antenna components while at the same time being substantially transparent to both z-mode and x-mode electromagnetic waves.

A billing system for determining package transportation charges. The billing system includes a reader to read a package identifier associated with said package and the reader generates a package identifier signal and transmits the same to a microprocessor. The billing system also includes a package sizer having a plurality of non-contact optical sensors located along each of an x, y and z axis, where each optical sensor is in a known position. The sensors are oriented relative to the conveyor so that packages passing over the sensors are detected by the sensors and produce a signal correlated to said package size. Also provided is a microprocessor to receive and correlate said package size and identifier signals, and to determine an appropriate shipping charge based upon the same. A weigh scale may also be incorporated into the system. A method of determining a transportation charge is also comprehended, which includes a selfdiagnostic initialization procedure.
