    摘要： A valve device that is securable to a cylinder includes a housing with a central passage in fluid communication with a first connection port that connects with a cylinder, and a second connection port including a passage that is in fluid communication with the central passage. The second connection port is configured to connect with a fluid flow line. A valve member is disposed within the second connection port and includes a movable member that engages with a seat to provide a fluid tight seal for the valve member in a closed position. The movable member is configured to be moved away from the seat so as to open the valve member and permit fluid to flow from the central passage of the valve housing around the movable member and through the second connection port while substantially preventing a backflow of fluids from a location external to the valve housing into the central passage.

    摘要： A flexible optical marker is applied to an optical scale substrate to make an optical scale assembly for an optical position encoder. The marker may be a limit marker, index marker, or other type of marker. The marker substrate may be a plastic film such as polyester, singulated from a “recombine” roll created by a web process. The marker has a microstructured pattern on one surface that is covered with a reflective metal coating. The marker also has an adhesive layer and is affixed to the optical scale substrate by a process of aligning the marker to an edge of the scale and then applying pressure to the upper surface of the marker. The marker may be applied with a handle portion that is separated from the marker after the marker is affixed. The marker may be especially useful with a flexible scale substrate such as a metal tape substrate. By affixing the marker to the scale substrate as a separate step of making an encoder scale, various benefits such as reduced inventory, cost, and lead time may be achieved.

    摘要翻译： 将柔性光学标记应用于光学尺度基板以制造用于光学位置编码器的光学尺度组件。 标记可以是限制标记，指数标记或其他类型的标记。 标记基底可以是由通过网状过程产生的“重组”辊形成的塑料膜，例如聚酯。 标记在一个表面上具有被反射金属涂层覆盖的微结构图案。 标记还具有粘合剂层，并通过将标记物与标尺的边缘对准并且然后向标记物的上表面施加压力的方法固定到光学秤基底上。 标记物可以在标记物固定之后施加与标记物分离的手柄部分。 该标记可能对于诸如金属带基材之类的柔性标尺基底特别有用。 通过将标记附着到刻度尺基板上，作为制作编码器刻度的单独步骤，可以实现诸如库存减少，成本和提前期的各种益处。

    摘要： An optical encoder includes a source of a light beam, an optical grating that generates a spatial pattern of interference fringes, and an optical detector which includes generally elongated detector elements that sample the interference fringe pattern at spatially separated locations along the direction of motion of the grating. Each detector element has one or more segments slanted along the direction of motion of the grating by an integer multiple of the period of an undesirable harmonic component of the fringe pattern, thereby spatially integrating the harmonic component and suppressing its contribution to an output of the detector. One specific detector type includes parallel elongated rectangular elements in a rectangular array that is rotated slightly about a Z axis; another type includes detector elements arranged to form a non-rectangular parallelogram. Another type of detector includes detector elements that each have multiple elongated rectangular segments which may be arranged into two non-parallel sets. The two sets can be further arranged in an alternating fashion so as to impart a zig-zag or chevron shape to each detector element.

    摘要： The format of the Presence Information Data Format—Location Object (PIDF-LO) as defined by the Internet Engineering Task Force (IETF) is extended or modified to accommodate, within the standard PIDF-LO format, an association of geospacial location to virtual content on the Internet. A filename of virtual content is associated with geospacial location information (either a specific location, zone, or direction). The filename is inserted into a section of a Presence Information Data Format-Location Object (PIDF-LO) compliant document as defined by the Internet Engineering Task Force (IETF). In this way, geospacial location information is associated with Internet based virtual content using a standard PIDF-LO format.
