    • A memory card connector includes an insulative housing having a rear terminal-mounting section and at least one side wall section extending forwardly from one end of the rear section defining a card-receiving space therebetween. A first conductive terminal is mounted on the housing and has a first contact portion with a first protrusion thereon. A second conductive terminal is mounted on the housing and has a second contact portion with a second protrusion thereon. The contact portions of the terminals are normally spaced from each other but are juxtaposed so that the contact portions and the protrusions are mutually engaged in response to a memory card inserted into the card-receiving space. The protrusions are offset from each other, whereby the first protrusion of the first terminal engages the second contact portion of the second terminal, and the second protrusion of the second terminal engages the first contact portion of the first terminal.

    • A new optical sensing device containing fiber Bragg gratings, a scanning bandpass filter, an interferometer and multiple photodetectors is disclosed. The present invention also describes a new system and method for fibre Bragg grating (FBG) sensor interrogation and multiplexing. The new system combines a scanning Fabry-Perot (SFP) bandpass filter used to wavelength-multiplex multiple gratings in a single fiber, and an unbalanced Mach-Zehnder fibre interferometer made with a 3×3 coupler to detect strain-induced wavelength shifts. A passive technique for interferometer drift compensation using non-sensing FBGs is included in the system. A complete prototype system interrogates four gratings in a single fiber at a Nyquist sampling rate up to 10 kHz, with a noise floor measured near 4 n&egr; Hz−1/2 above 0.1 Hz. The inclusion of the interferometer drift compensation technique is shown to make quasi-static measurements feasible.
    • 公开了一种包含光纤布拉格光栅,扫描带通滤波器,干涉仪和多个光电探测器的新型光学感测装置。 本发明还描述了用于光纤布拉格光栅(FBG)传感器询问和复用的新系统和方法。 新系统结合了用于在单个光纤中波长复用多个光栅的扫描法布里 - 珀罗(SFP)带通滤波器和用3x3耦合器制成的不平衡马赫 - 曾德尔光纤干涉仪,以检测应变诱发的波长漂移。 系统中包含使用非感应FBG的干涉仪漂移补偿的被动技术。 完整的原型系统以高达10 kHz的奈奎斯特采样率在单根光纤中询问四个光栅,噪声基底在0.1赫兹附近测得。 显示了包含干涉仪漂移补偿技术,使准静态测量成为可能。

    • The invention was originally developed to determine the strain-relief capability of a fusion splice protector as well as the compressive stress imparted to a fusion splice by the splice protector. The invention also permits performance and comparative analyses of splice protectors as well as any package in which the optical fiber is at least partially disposed. To those ends a fiber Bragg grating (FBG) is axially arranged relative to the package such that a free or reference section of the FBG protrudes from the package while a shielded section lies within the package. Broadband light is supplied to the FBG which reflects certain wavelengths that are measured by an optical spectrum analyzer. The FBG reflected spectra will be split into two peaks as the reference and shielded sections experience different amounts or types of stress thereby providing a powerful analysis tool. A wavelength shift in the reflected spectra reveals the amount of stress experienced by the reference and free sections and permits a qualitative and quantitative analysis of the stress applied by the package and the package's ability to protect fiber from stress (e.g. such as that imposed by a tension pull test). Measurements may be made after a variety of conditions are changed such as splice protector curing, axial tension application, axial tension release, time, and age accelerating environments. Comparative studies and various other calculations may also be performed to evaluate different packages.
    • 本发明最初被开发用于确定熔接保护器的应变消除能力以及由熔接保护器施加到熔接的压缩应力。 本发明还允许对接头保护器的性能和比较分析以及光纤至少部分地布置在其中的任何封装。 为此,光纤布拉格光栅(FBG)相对于封装件轴向地布置,使得FBG的自由或参考部分从封装突出,而屏蔽部分位于封装内。 宽带光被提供给反射由光谱分析仪测量的某些波长的FBG。 FBG反射光谱将被分为两个峰,因为参考和屏蔽部分经历不同的应力量或类型,从而提供了强大的分析工具。 反射光谱中的波长偏移显示了参考和自由部分所经历的应力量,并允许对包装施加的应力的定性和定量分析以及包装保护纤维免受应力的能力(例如,由 拉力试验)。 可以在各种条件改变之后进行测量,例如接头保护器固化,轴向张力施加,轴向张力释放,时间和年龄加速环境。 还可以进行比较研究和各种其他计算来评估不同的包装。
