    • A VCSEL (vertical cavity surface emitting laser) is formed on the top surface of the substrate having an opposed bottom surface. In one exemplary embodiment, the opposed bottom surface is polished and coated with an anti-reflective coating. A photodetector is disposed beneath the bottom surface and is capable of detecting light emitted by the VCSEL. In another embodiment, an angle selective filter is disposed between the photodetector and the unpolished and uncoated bottom surface. The apparatus urges light emitted by the VCSEL to be detected by the photodetector and limits light from other sources from reaching the photodetector. A method for monitoring the optical output of a VCSEL includes providing one of the exemplary apparatuses, causing the VCSEL to emit light that is detected by the photodetector, and adjusting the optical output of the VCSEL based on the amount of light detected by the photodetector.
    • 在具有相对的底面的基板的顶表面上形成VCSEL(垂直腔表面发射激光器)。 在一个示例性实施例中,相对的底表面被抛光并涂覆有抗反射涂层。 光电检测器设置在底表面下方并且能够检测由VCSEL发射的光。 在另一个实施例中,角度选择滤光器设置在光电检测器和未抛光和未涂覆的底表面之间。 该装置促使由VCSEL发射的光被光检测器检测,并限制来自其它光源的光到达光电检测器。 用于监视VCSEL的光输出的方法包括提供示例性装置中的一个,使VCSEL发射由光电检测器检测的光,以及基于由光电检测器检测到的光的量来调整VCSEL的光输出。

    • An ambulatory pump (10) for dispensing a liquid under pressure at a predetermined flow rate includes a housing (12) having first and second end caps (14, 16) positioned on the housing (12) and enclosing the housing (12). Each end cap (14,16) has a port (18,20) formed therein. A pressurizable bladder (22) is carried by the housing (12) for receiving and dispensing the liquid. The bladder (22) is expandable between an unexpanded condition and an expanded condition. The bladder (22) has a free end (30) defining an opening in flow communication with the second end cap port (20) and a fixed end defining an opening in flow communication with the first end cap port (18). A section of flexible tubing (40) is carried by the housing (12) and extends between and is in flow communication with the bladder free end (30) opening and the second end cap port (20). The pump (10) includes a connecting member (32) positioned between the flexible tubing (40) and the bladder (22) that is configured to provide indication of the volume of the pump (10). The connecting member (32) moves longitudinally within the housing (12) to indicate the volume of liquid in the pump (10) as the bladder (22) moves between the expanded and unexpanded conditions. The pump (10) includes an inlet port (20) at the second end cap (16) and a tubing set (50) extending from the first end cap port (18) to dispense the liquid to a patient.
    • 用于以预定流量在压力下分配液体的移动泵(10)包括具有定位在壳体(12)上并封闭壳体(12)的第一和第二端盖(14,16)的壳体(12)。 每个端盖(14,16)具有形成在其中的端口(18,20)。 可加压的囊(22)由壳体(12)承载以接收和分配液体。 膀胱(22)可在未膨胀状态和膨胀状态之间膨胀。 气囊(22)具有限定与第二端盖端口(20)流动连通的开口的自由端(30)和限定与第一端盖端口(18)流动连通的开口的固定端。 柔性管道(40)的一部分由壳体(12)承载并且在气囊自由端(30)开口和第二端盖端口(20)之间延伸并与之流动连通。 泵(10)包括定位在柔性管(40)和囊(22)之间的连接构件(32),其构造成提供泵(10)的体积的指示。 连接构件(32)在壳体(12)内纵向移动,以在囊(22)在膨胀和未膨胀状态之间移动时指示泵(10)中的液体体积。 泵(10)包括在第二端盖(16)处的入口端口(20)和从第一端盖端口(18)延伸以将液体分配给患者的管道组件(50)。

    • A horned interferometer antenna apparatus has parallel plates spaced apart and rigidly connected together by a separator. In the space between the parallel plates is a plurality of antenna elements. The parallel plates each have a free edge which diverge from the other free edge defining an aperture for receiving electromagnetic waves. The horned interferometer antenna apparatus has enhanced directivity and is used for passive radio direction finding. An interferometer system comprises a horned interferometer antenna apparatus, a multi channel receiver and a phase comparator. The interferometer system measures the angle of arrival of an incident electromagnetic wave or signal based on the phase difference between the signal as received by the antenna elements of the horned interferometer antenna apparatus.
