Abstract: A method and apparatus for creating a phase shifting mask and a structure mask for shrinking integrated circuit designs. One embodiment of the invention includes using a two mask process. The first mask is a phase shift mask and the second mask is a single phase structure mask. The phase shift mask primarily defines regions requiring phase shifting. The single phase structure mask primarily defines regions not requiring phase shifting. The single phase structure mask also prevents the erasure of the phase shifting regions and prevents the creation of undesirable artifact regions that would otherwise be created by the phase shift mask. Both masks are derived from a set of masks used in a larger minimum dimension process technology.

Abstract: A gutter protector for preventing leaves and other debris from entering into a gutter that fits independently into standard gutter without fasteners such as nails or screws or any attachment to the roof, fascia or any other part of the building. The gutter protector consists of an inner wall which fits against the rear wall of standard gutter while seated upon the bottom wall of the gutter and a curved section that allows water to flow over the flat portion of the gutter protector through a uniform space between the gutter protector and the gutter created by a clip in the gutter protector which attaches to the gutter. The uniform space does not allow leaves or other debris larger than said uniform space to enter the gutter but maintains a space for a constant flow of water into the gutter.

Abstract: Por consiguiente, el elemento receptor 3 recibe la parte de luz emitida, que se retrodispersa en el medio dispersante, sugerido en la Figura 1 mediante un sombreado diagonal, en el intervalo de solapamiento 6. Como se señala en la Figura 1, el elemento emisor 1 irradia un corto impulso de luz 7 de aprox. 10 nanosegundos. El transcurso temporal 8 de la proporción retrodispersada del impulso emitido de luz 7 se representa asimismo en la Figura 1. La dependencia temporal de la amplitud de la luz retrodispersa recibida por el elemento receptor 3 se encuentra en relación directa con la separación de la zona espacial, de la que procede la luz retrodispersada. Es decir, cuanto más lejos se separe la zona espacial del elemento receptor 3, tanto menor será la proporción retrodispersada del impulso de luz emitida 7, y tanto menor será la separación de la zona espacial respecto al elemento receptor 7, tanto mayor será la proporción del impulso emitido de luz 7 retrodispersada en esta zona espacial. Envez de recibir, como se representa en la Figura 1, con un único elemento receptor óptico 3 un transcurso de luz retrodispersa 8 en función de la distancia de zonas espaciales separadas a diferente distancia, puede también recibirse, como se describe en la DE 196 29 712 A1, con varios elementos receptores, la luz retrodispersa de zonas espaciales diferentemente separadas. Los ejes ópticos de los elementos receptores presentan, además, diferentes ángulos respecto al eje óptico del elemento emisor. Al elemento receptor 3 se le conecta una unidad de evaluación 9, que determina el alcance visual en la zona delante del vehículo a partir de la señal de salida del elemento receptor 3 que recibe la luz retrodispersa. En las Figuras 2, 4 y 6 se representan los diagramas de flujo de tres métodos diferentes, acorde a los cuales la unidad de evaluación 9 puede determinar el alcance visual presente a partir de la señal de salida del elemento óptico receptor 3. Antes de la medida real (en línea) del alcance visual, se determinan (fuera de línea) en un primer paso procedimental 21 las clases individuales de alcance visual según el llamado método de patrones Fuzzy (difusos). Este método de patrones difusos se conoce gracias a U. Prieber: "Procesamiento de Informaciones Multisensoriales con Clasificación Fuzzy", 3º Simposio de Ingeniería de Microsistemas, Microsistemas para Ingeniería de Procesos y de Fabricación, Regensburg 1993, pág. 169-179.
