Abstract: A louver blade comprises an elongated body made of extruded plastic having first and second plastic strips disposed within and off-center from the longitudinal axis of the body. A method for making a louver blade comprises extruding plastic in a shape of a louver blade into a die; feeding first and second plastic strips through a cavity of the die; cooling the extruded louver blade; and cutting the extruded louver blade into desired length.

Abstract: A solar cell or solar module is measured during a short pulse of light in such a way that the resulting data for current and voltage at each light intensity is the same as would be measured under steady-state illumination conditions and therefore predictive of the actual performance of the solar cell or solar module in sunlight. A varying voltage is applied to the terminals of the solar cell during a light pulse so that the instantaneous current at a given voltage and light intensity during the light pulse is the same as would be measured under constant illumination at that same given intensity. A constant voltage is modified by a small signal correction that is proportional to the terminal current. Or, the small signal correction is proportional to the light intensity. An analog feedback circuit is constructed using the terminal current or light intensity for feedback in order to provide the requisite varying voltage. The varying voltage may also be supplied by digital synthesis.

Abstract: A memory module includes a plurality of memory components mounted on a printed circuit board, and a plurality of passive components embedded within the board directly underneath the memory components to minimize the space occupied by the passive components and the lengths of the required conductive traces. The passive components and the memory components are connected by conductor-filled vias between the contacts of the embedded components and the memory components mounted above them on the board surface. The passive components may be thick film resistors, either series damping resistors or differential damping resistors. By embedding the resistors directly beneath the memory components, there is enough space on the board to provide a set of termination resistors for each of the several memory components on the board, thereby eliminating the need for a single resistor to be shared by two or more memory components, resulting in more precise output signals.

Abstract: An extrusion product or profile is formed by extrusion of a cellular compound to form a base and then subsequent extrusion of a non-cellular compound to form an attached flexible strip. The final product or profile is used as a garage door weatherstrip in which the cellular base is mounted against the door jamb and the strip of flexible non-cellular material extends out from the cellular base to prevent the flow of air through openings between doors and adjacent jambs or frames.

The final product or profile is used as a garage door weatherstrip in which the cellular base is mounted against the door jamb and the strip of flexible non-cellular material extends out from the cellular base to prevent the flow of air through openings between doors and adjacent jambs or frames. The process for forming such a product involves sequential extrusion of the two portions of the product. First, a cellular base is extruded through a die and vacuum sizer and allowed to cool. Next, a saddle die is used to apply the flexible non-cellular strip to a portion of the cellular base.
