Abstract: Electromagnetic Interference (EMI) shields for a direct-view display having a direct-view display panel and an outer panel that provides an outer surface for the direct-view display. These EMI shields include a conductive mesh having an array of gaps therein. The conductive mesh is configured to shield at least some of the EMI that is emitted by the direct-view display panel. An optical redirecting structure is also included, that is configured to redirect at least some optical radiation that is emitted from the direct-view display panel that would strike the conductive mesh, through the gaps in the conductive mesh. The EMI shield is configured to mount between the direct-view display panel and the outer panel such that the optical redirecting structure is adjacent the direct-view display panel and the conductive mesh is remote from the direct-view display panel.

Abstract: Methods of forming optoelectronic devices include forming an electrically conductive layer on a first surface of a substrate and forming a mirror backing layer from the electrically conductive layer by forming an endless groove that extends through the electrically conductive layer. A step is then performed to remove a portion of the substrate at a second surface thereof, which extends opposite the first surface. This step exposes a front surface of the mirror backing layer. An optically reflective mirror surface is then formed on the front surface of the mirror backing layer.

Abstract: A microelectromechanical structure capable of switching optical signals from an input fiber to one of two or more output fibers. In one embodiment, the MEMS optical cross-connect switch comprises a first microelectronic substrate having a pop-up mirror disposed on the surface of the substrate and a rotational magnetic field source, such as a variably controlled magnetic field source. The rotational magnetic field source allows for reliable actuation of the pop-up mirror from a non-reflective state to a reflective state. Additionally the invention is embodied in a MEMS optical cross-connect switch having a first microelectronic substrate having a pop-up mirror disposed on the surface of the substrate and a positioning structure disposed in a fixed positional relationship relative to the first substrate. The positioning structure may comprise a positioning structure extending from a second microelectronic substrate that is in a fixed positional relationship relative to the first microelectronic substrate. The positioning structure serves to restrict further movement of the pop-up mirror when the pop-up mirror has been actuated into a reflective state.

Abstract: A method and system for efficiently analyzing databases. In one embodiment, the invention is used to analyze data represented in the form of attribute-value (a-v) pairs. A primary step in building the ontology is to identify parent, child and related a-v pairs of each given a-v pair in the database. A parent is an a-v pair that is always present whenever a given a-v pair is present. A child is an a-v pair that is never present unless the given a-v pair is present. Related pairs of a given a-v pair are those a-v pairs present some of the time when a given a-v pair is present. The system calculates relationships between a-v pairs to produce tables of a-v pairs presented according to the relationships. The user performs additional analysis by investigating the a-v pair relationships through a graphical user interface. Additional visualizations of the data are possible such as through Venn diagrams and animations. Plain-text data documents collected, for example, from the Internet can be analyzed. In this case, the system pre-processes the text data to build a-v pairs based on sentence syntax.

Abstract translation: 一种有效分析数据库的方法和系统。 在一个实施例中，本发明用于分析以属性值（a-v）对的形式表示的数据。 构建本体的一个主要步骤是识别数据库中每个给定a-v对的父，子和相关a-v对。 父母是一个a-v对，每当一个给定的a-v对存在时总是存在的。 一个孩子是一个永远不存在的a-v对，除非给定的a-v对存在。 给定a-v对的相关对是当存在给定a-v对时的某些时间的那些a-v对。 系统计算a-v对之间的关​​系，以产生根据关系呈现的a-v对的表。 用户通过图形用户界面调查a-v对关系来执行额外的分析。 数据的其他可视化是可能的，例如通过维恩图和动画。 可以分析从互联网收集的纯文本数据文件。 在这种情况下，系统会根据句子语法对文本数据进行预处理，以构建a-v对。

Abstract: Microelectromechanical actuators include at least one arched beam which extends between spaced apart supports on a microelectronic substrate. The arched beams are arched in a predetermined direction and expand upon application of heat thereto. A coupler mechanically couples the plurality of arched beams between the spaced apart supports. Heat is applied to at least one of the arched beams to cause further arching as a result of thermal expansion thereof, and thereby cause displacement of the coupler along the predetermined direction. Internal heating of the arched beams by passing current through the arched beams may be used. External heating sources may also be used. The coupler may be attached to a capacitor plate to provide capacitive sensors such as flow sensors. The coupler may also be attached to a valve plate to provide microvalves. Compensating arched beams may be used to provide ambient temperature insensitivity.
