摘要:
The antiwear performance of turbine oils containing polymerized amine antioxidants and antiwear additives is maintained at or enhanced beyond the level as that of turbine oils containing monomeric amine antioxidants by employing as the antiwear additive a resorcinol bis(diphenylphosphate) (RDP). The deposit formation resistance performance of turbine oils containing monomeric and/or polymeric amine antioxidant is improved by employing RDP.

The deposit formation resistance performance of turbine oils containing amine antioxidants and antiwear additives is enhanced beyond the level of that of turbine oils containing tricresyl phosphate antiwear additive by employing as the antiwear additive a 4,4′-(Isopropylidenediphenyl)bis(diphenyl phosphate).
摘要:
System and method for reducing failures due to hinge memory in a microdisplay display system. A preferred embodiment includes setting the state of each micromirror in a digital micromirror device based on an image being displayed, recording a usage history for the micromirrors, and providing a sequence of states to each micromirror when the display system is in an inactive mode. The sequence of states provided to a micromirror is based on the micromirror's usage history. The operation of the micromirrors while a display system containing the digital micromirror device is not in active use can help to reverse or eliminate hinge memory, thereby extending the lifetime of the digital micromirror device.
摘要:
A process for protecting a MEMS device used in a UV illuminated application from damage due to a photochemical activation between the UV flux and package gas constituents, formed from the out-gassing of various lubricants and passivants put in the device package to prevent sticking of the MEMS device's moving parts. This process coats the exposed surfaces of the MEMS device and package's optical window surfaces with a metal-halide film to eliminate this photochemical activation and therefore significantly extend the reliability and lifetime of the MEMS device.

摘要:
A method and system of reducing the permanent accumulated deformation of a deflectable member of a micromechanical device through thermal stabilization. The accumulated deformation is due to the repeated bending or twisting of a flexible component of the micromechanical deice typically the repetitive deformation of a flexible hinge connecting a rigid member to substrate. After the device is fabricated, passivated (316), and packaged (322), the packaged device is baked (326) at a temperature of at least 120° C. A 150° C. bake for 12 to 16 hours is preferred. Lower temperatures required longer baking periods.
