Screen protector
InactiveUS7070837B2Prevents orMinimize formationLiquid crystal compositionsAdhesive processesRefractive indexEngineering
A plastic film screen protector that prevents interference patterns from arising when the film touches the screen is described. The advantages are accomplished by the film having a slightly roughened surface so that the majority of the film facing an electronic device screen does not substantially touch the screen. These physical aberrations prevent Newton ring interference patterns and spots caused by refractive index differences between air and the film material.

Systems and methods of blood-based therapies having a microfluidic membraneless exchange device
InactiveUS20060076295A1Reduces undesirable activationMinimizing bioincompatibilitiesComponent separationMedical devicesDiffusionThin layer
The present invention is directed to devices, systems and methods for removing undesirable materials from a sample fluid by contact with a second fluid. The sample fluid flows as a thin layer adjacent to, or between, concurrently flowing layers of the second fluid, without an intervening membrane. In various embodiments, a secondary separator is used to restrict the removal of desirable substances and effect the removal of undesirable substances from blood. The invention is useful in a variety of situations where a sample fluid is to be purified via a diffusion mechanism against an extractor fluid. Moreover, the invention may be used for the removal of components from a sample fluid that vary in size. When blood is the sample fluid, for example, this may include the removal of ‘small’ molecules, ‘middle’ molecules, macromolecules, macromolecular aggregates, and cells, from the blood sample to the extractor fluid.

A novel integrated circuit (IC) chip package structure and underfill process which reduces stress applied to corners of a flip chip in an IC package structure during the application of an adhesive material between the flip chip and a carrier substrate is disclosed. The process includes providing a dam structure on a carrier substrate; attaching solder bumps of an inverted flip chip to the carrier substrate; injecting an adhesive material between the flip chip and the carrier substrate at multiple injection points located along adjacent edges of the flip chip; and injecting a sealant material around the adhesive material. During application of the adhesive material and the sealant material to the IC package structure in the underfill process, the dam structure reduces stress applied to the corners of the flip chip. This prevents or at least reduces de-lamination of dielectric layers on the flip chip.

ActiveUS7140560B2Prevents orReduce thermal stressLiquid surface applicatorsContinuous combustion chamberEngineeringFuel line
A deflector at the downstream end of a fuel tube deflects incoming fuel into an annular fuel channel in a fuel swirler of an injector. The deflector prevents direct impact of the cooler fuel on the exposed walls of the swirler body. The deflector can be formed by a tab or other integral portion of the heatshield, or as a separate piece fixed to the heatshield or swirler body. The deflector minimizes disruption of flow through any flow slots that are covered by the deflector, and may have i) a relatively small circumferential extent, such that the deflector covers only a few flow slots, ii) flow openings or slots that allow a portion of the fuel to flow inwardly of the deflector into the otherwise covered flow slot(s), or iii) a space or gap between the side(s) of the deflector and the inner walls of the annular channel.
