    • A chemiluminescent assay to determine the presence and/or amount of one or more labeled target molecules in a sample is described in which the surface layer of a solid support is contacted with a composition comprising first and second chemiluminescent substrates capable of being activated by first and second enzymes, respectively. A plurality of probes are disposed on the surface layer in discrete areas. At least some of the probes are bound to a first enzyme conjugate comprising the first enzyme and at least some of the probes are bound to a second enzyme conjugate comprising the second enzyme. The resulting chemiluminescent signals are then detected. The method can be used to compare two biological samples (e.g., mRNA populations from different cells) on the same support surface or to provide a chemiluminescent control signal for normalizing chemiluminescent assay data from a biological sample.
    • 描述了用于确定样品中一种或多种标记的靶分子的存在和/或量的化学发光测定法,其中固体支持物的表面层与包含能够被第一和第二化学发光底物活化的第一和第二化学发光底物的组合物接触, 第二种酶。 多个探针设置在离散区域的表面层上。 至少一些探针与包含第一酶的第一酶结合物结合,并且至少一些探针与包含第二酶的第二酶缀合物结合。 然后检测所得到的化学发光信号。 该方法可用于比较两个生物样品(例如,来自不同细胞的mRNA群体)在相同的支持物表面上,或提供化学发光控制信号,用于从生物样品中归一化化学发光测定数据。

    • An earphone has a body housing a transducer that is capable of generating an acoustic signal and directing the acoustic signal to an outlet in the body, the body being positionable in, on, or near an ear of user so that the acoustic signal can be directed into the ear canal of the user. The earphone also has an ear coupling mechanism comprising a sealing mechanism with a sealing member that is adapted to contact a portion of the ear of the user to at least partially create a seal between the ear canal and the external environment and a venting mechanism capable of venting air between the ear canal and the external environment, the venting mechanism comprising an air conduit that is adapted to communicate on one end with the ear canal and at another end with the external environment so that air can flow through the conduit to equalize a pressure differential across the sealing mechanism. The air conduit is sized and shaped so as to provide an improved audio performance over an earphone without the air conduit.

    • A flexible extension storage enclosure for folding travel trailers that is selectively secured to the underside of a folding trailer extension after it has been deployed from the main body of the travel trailer. The storage extension enclosure provides additional usable weather tight storage area beneath the extension by using a combination of track insertable support rails and a plurality of wall surface mounted snaps to define selectively accessible integrated storage compartment there beneath with a selective access closure.

    • A chain tension sensor for a chain conveyor, the conveyor including a frame and a chain having a plurality of flights. The tension sensor includes a reaction arm and a load sensing pin. The reaction arm includes a first end, a second end opposite the first end, and a load pad. The first end is pivotably coupled to the frame by a pivot pin defining a pivot axis. The load pad is adjacent the conveyor chain and positioned to contact flights passing the load pad. The flights contacting the load pad exert a force on the reaction in a direction that is perpendicular to the pivot axis. The load sensing pin is coupled to the reaction arm such that the load sensing pin senses the force that is exerted by the flights.
    • 用于链式输送机的链式张力传感器,该输送机包括具有多个飞行的框架和链条。 张力传感器包括反作用臂和负载传感销。 反作用臂包括第一端,与第一端相对的第二端和负载垫。 第一端通过限定枢转轴线的枢轴枢转地联接到框架。 负载垫与输送链相邻并且定位成与经过负载垫的接触点接触。 与负载垫接触的飞行器在垂直于枢转轴线的方向上对反作用力施加力。 负载感测销耦合到反作用臂,使得负载感测销感测到由翼片施加的力。
