Abstract:
A display including an image-generating panel and at least one contrast-enhancing panel, a cross BEF collimator between a backlight and one of the panels, and a polarization-preserving diffuser (e.g., holographic diffuser) between the panels. Typically, the contrast panel is upstream of the image panel, and a reflective polarizer is positioned between the cross BEF or and contrast panel, with the reflective polarizer oriented relative to an initial polarizer of the contrast panel. Polarization of light transmitted by the reflective polarizer matches that transmitted by the initial polarizer. Collimated light propagating from the cross BEF collimator toward the contrast-enhancing panel is given a polarization bias by the reflective polarizer, which reflects incorrectly polarized light back toward the cross BEF collimator. Alternatively, the reflective polarizer may be positioned between the cross BEF collimator and the image-generating panel when the image-generating panel is upstream of the contrast-enhancing panel.
Abstract:
A high contrast high resolution display is produced using an image chain comprising a plurality of downstream high resolution modulators. The modulators may be illuminated by a locally dimmed backlight. Polarization control is maintained throughout the image chain via reference and analyzing polarizers combined with non-depolarizing layers. The modulators are grayscale and modulate at the sub-pixel level. A color panel may be maintained for embodiments that require color. Diffusion in the chain is matched to a resolution of the image content carried in the light such that the effects of local dimming and sub-pixel resolution are preserved. Brightness enhancement films may be utilized to enhance brightness and maintain polarization control.

Methods for Implementation of a Switching Function in a Microscale Device and for Fabrication of a Microscale Switch. According to one embodiment, a method is provided for implementing a switching function in a microscale device. The method can include providing a stationary electrode and a stationary contact formed on a substrate. Further, a movable microcomponent suspended above the substrate can be provided. A voltage can be applied between the between a movable electrode of the microcomponent and the stationary electrode to electrostatically couple the movable electrode with the stationary electrode, whereby the movable component is deflected toward the substrate and a movable contact moves into contact with the stationary contact to permit an electrical signal to pass through the movable and stationary contacts. A current can be applied through the first electrothermal component to produce heating for generating force for moving the microcomponent.
Abstract:
Edge lit displays are lit via a set (or individual) lighting elements. Each element projects light onto, for example, a zone which is then utilized directed as a backlight toward an LCD panel. An amount of light incident on any area (e.g., pixel) of the LCD panel (or SLM/series of SLMs) is calculated based on a sum of contributions from each zone. A similar process may be utilized for other lighting configurations. An amount of modulation performed by the LCD panel is then calculated based at least in part on lighting from the zones which may include brightness and varying levels of color content.
Abstract:
A semiconductor device package comprises a container having a base and side walls of an electrically insulating material. A semiconductor device chip is disposed on the base, and a lead frame extends through the side walls. At least one electrical conductor couples the lead frame to the chip. A first layer of an electrically insulating cured gel covers the chip and the lead frame, and a second layer of an electrically insulating cured gel covers at least the portion of the first layer that covers the chip, but does not extend to the side walls. In one embodiment, the second layer has the shape of a dome. In a preferred embodiment the gel comprises silicone. In another embodiment a third layer of conformal insulating material is disposed on the second layer and essentially fills the container. Also is described is a method of making the package for use with RFLDMOS chips.
Abstract:
A flexible heat pipe is disclosed for use with evaporator and condenser elements for removing heat from electronic components. The flexible heat pipe comprises a bellows member fixed at one end to a condenser member and at an opposite end to an evaporator member. A cable artery is disposed within the bellows and is fixed at one end to the evaporator, and slidingly engages the condenser at the opposite end. The bellows acts as a flexible vapor envelope, and the cable artery acts as a flexible wick for directing condensed working fluid from the condenser back to the evaporator. The sliding connection between the cable artery and the condenser allows relative axial movement, and the inherent flexibility of the cable artery allows relative lateral movement. Thus, the condenser and evaporator can move in all directions with respect to each other, which can provide desired vibration isolation of the two components.

Abstract:
A digital multimeter automatically records measurements of electrical or physical parameters. The multimeter may record the measurements based on events such as the passage of time, fluctuations or deviations in the measurements, or user inputs. In some examples, the digital multimeter operates at a reduced power setting during automatic recording operations.
