摘要:
Described herein are diffraction gratings and methods for the manufacture thereof. One method comprises applying a force to a substrate to strain the substrate, disposing a thin film on at least a portion of the substrate, and reducing the force applied to the substrate, thereby causing the thin film to buckle.

By exposing dielectrics to a strong electric field, anisotropic characteristics may be introduced into the dielectric. This may result in the dielectric having different dielectric constants in different directions. As integrated circuits scale, importance of line to line capacitance in one plane increases. Thus, in some embodiments, the dielectric constant of the oriented dielectric may be lower in the plane that controls line to line capacitance.

A method and apparatus for estimating a lever arm correction between the wide beam antenna and the spot beam antenna in a navigational satellite system is disclosed. A prescribed satellite maneuver is used to increase the accuracy of the predicted satellite attitude in determining the lever arm, and lever arm corrections are provided from a ground segment to navigation receivers using curve fit coefficients to permit long range estimates and to minimize data transmission requirements.

A saddle tee assembly for use with an irrigation line. The saddle tee assembly generally includes a collar portion having a bore therethrough; a strap portion for securing the collar to an irrigation line; and a tool having a passage therethrough with an opening in fluid communication with the passage. The tool may be receivable in the bore for puncturing the irrigation line. In a preferred form, the saddle tee assembly also includes an anti-rotation interface between the collar portion and the tool. The anti-rotation interface includes a first stop on the collar portion and corresponding second stops on the tool. The first and second stops being engageable to align a received tool in a predetermined orientation and restrict unintentional rotation of the tool.

Moisture sensor devices and methods associated with operation of the moisture sensor devices are disclosed herein. One embodiment includes a moisture sensor device comprising a probe forming a capacitor and adapted to be positioned within soil; a controller coupled to the probe, the controller comprising a variable frequency oscillator, the frequency of the variable frequency oscillator varies as a function of a capacitance of a capacitor, the capacitance varies as a function of a moisture content of the soil; a reference oscillator; and a circuit for comparing the frequency of the variable frequency oscillator to a frequency of the reference oscillator; and a switch coupled to the circuit and adapted to be coupled to a power output line of an irrigation controller and a power actuation line coupled to a valve.
摘要:
A decorative laminate assembly having, in descending superimposed relationship, a decorative layer, an impregnated tie sheet and a substrate. Preferably, the laminate assembly also includes an overlay layer on top of the decorative layer, and the substrate preferably contains FRP. The tie sheet is preferably impregnated with a bridging agent having a mixture of MEK, an acrylic ester, a polyester and an organic peroxide. Surprisingly, it has been discovered that impregnated tie sheet of the present invention not only bonds remarkably well to the melamine resin treated (or untreated) decorative layer, but also simultaneously bonds extremely well to an FRP substrate. The decorative laminate assemblies of the present invention can be used for a variety of purposes, including wall panels and flooring applications. When the present invention is used for flooring applications, it is preferred that the overlay layer has enhanced wear resistant qualities. The chemical mixture of the bridging agent used in the tie sheet can also be used without any sheet and can be instead deposited directly between two incompatible layers of a laminate.
