    • A truck towing system is described. The truck towing system provides for a first truck to tow a second truck in a back to front relationship, i.e., the front portion of the second truck (the towed truck) is connected or attached to a rear portion of the first truck (the towing truck). The truck towing system includes an upper member to removably connect with a first truck. A middle member joins the upper member and a lower member in a fixed engagement. The lower member supports a front portion of a second truck. A beam member is removably engaged to the lower member, and the beam member extends and retracts from an interior of the lower member. The beam member connects to a rear portion of the second truck.
    • 描述了卡车牵引系统。 卡车牵引系统提供一辆第一辆卡车以一种前后关系牵引第二辆货车,即第二辆卡车(牵引车)的前部连接或连接到第一辆卡车的后部(牵引 卡车)。 卡车牵引系统包括可拆卸地与第一卡车连接的上部构件。 中间构件以固定的接合方式连接上部构件和下部构件。 下部构件支撑第二卡车的前部。 梁构件可移除地接合到下构件,并且梁构件从下构件的内部延伸和缩回。 梁构件连接到第二卡车的后部。

    • A medical blood pressure transducer that provides an identifier to a monitor that conveys characteristics of the transducer. The monitor can use the information to decide whether to function, or in calibration of the system. The transducer may be part of a disposable blood pressure monitoring system, and may include two transducers closely-spaced to provide two separate but identical outputs. In this way, the transducer may be connected to both a patient monitor and a cardiac output monitor at the same time measurements from a single line can be simultaneously supplied to two separate monitoring devices (for example a patient monitor and a cardiac output monitor). The identifier for the transducer may be circuitry, specifically a resistance/capacitance (RC) combination that possesses a characteristic time constant.
    • 一种医用血压传感器,其向传送换能器特征的监视器提供标识符。 监视器可以使用信息来决定是否运行,也可以在系统校准中使用。 换能器可以是一次性血压监测系统的一部分,并且可以包括紧密间隔开的两个换能器,以提供两个单独但相同的输出。 以这种方式,换能器可以同时连接到患者监护仪和心输出量监测器,同时来自单线的测量可以同时提供给两个分开的监测装置(例如患者监护仪和心输出量监测器)。 换能器的标识符可以是具有特征时间常数的电路,特别是电阻/电容(RC)组合。

    • A multiple lumen catheter having a soft, tapered multiple lumen distal tip for insertion into a body vessel. One of the lumens is sized to pass over a guidewire such that the catheter can be inserted into the body vessel using the Seldinger technique. At least one medical implement lumen is used for placement or positioning of a biomedical sensor or other medical implement. For example, at least one optical fiber passing through the medical implement lumen may transmit and receive light at the distal tip for measuring oxygen saturation of the blood. The catheter may have a cylindrical catheter body to which the soft distal tip attaches. The soft tip reduces the possibility of vessel or tissue puncture and abrasion. The tip is constructed of a soft plastic or pliable material that yields easily when force is applied. For example, the tip may be made of a softer material than the catheter body, or if made of the same material, the tip can be configured with thinner walls or a higher air-to-material ratio cross-section. Various geometrical configurations and combinations of materials can be used to decrease the flexible resistance of the tip to an applied load. One particular useful application for the catheter of the present invention is as a central venous catheter equipped with fibers for measuring oximetry. The fibers extend to the distal end of the tip and are preferably secured therein with minimal adhesive so as to limit the stiffness added to the tip. One particular useful construction is to secure the fibers within the medical implement lumen using adhesive only along a length of between about 0.5–3.5 mm.
