    • In a pre-filled Foley catheter for urine drainage, the conventional clip for releasing sterile water from a bulb (21) at the proximal end of the catheter, to fill the anchor bulb (20) at the distal end of the device, is replaced by a plug (25) which has an annular portion connected to a thin stem (27) by a circle of weakness. Snapping the stem (27) from the annulus provides a tactile signal through the opaque latex lumen that the catheter has been actuated. There is no separate clip to be disposed of. The interface between the latex and the plug remains undisturbed. Further improvement in the shelf-life and convenience of use of the catheter is delivered by the use of a sleeve, which can be of shrink-wrap material, around the bulb (21) and optionally also around the drain coupling (15) of the catheter. Apparatus for placing the plug and the sleeve is also described.
    • 在用于排尿的预填充的Foley导管中,用于从导管的近端处的灯泡(21)释放无菌水以填充设备远端处的锚定灯泡(20)的常规夹子被替换 通过具有环形部分的插头(25),所述环形部分通过一个弱点连接到细的杆(27)。 从环形空间中抓住杆(27)通过导管已被致动的不透明胶乳腔提供触觉信号。 没有单独的剪辑被丢弃。 胶乳和塞子之间的界面保持不受干扰。 导管的使用寿命和使用便利性的进一步改进是通过使用可以是包封材料的套筒(其可以是包封材料),并且可选地也围绕灯泡(21)的排水接头(15) 导管。 还描述了用于放置插头和套筒的装置。

    • A computer-readable medium comprises data structure for providing information about levels of similarity between pairs of N documents. The data structure comprises a plurality of entries of similarity values representing levels of similarity for a plurality of pairs of the documents. Each of the similarity values represents a level of similarity of one document of a given pair relative to the other document of the given pair. The similarity value of each entry is greater than a threshold similarity value that is greater than zero. The plurality of similarity-value entries are fewer than N2−N in number if the similarity values are asymmetric with regard to document pairing, and the plurality of similarity-value entries are fewer than N 2 - N 2 in number if the similarity values are symmetric with regard to document pairing. A method and apparatus for generating the data structure are described.

        • A method is provided for forming a metal/semiconductor/metal (MSM) back-to-back Schottky diode from a silicon (Si) semiconductor. The method deposits a Si semiconductor layer between a bottom electrode and a top electrode, and forms a MSM diode having a threshold voltage, breakdown voltage, and on/off current ratio. The method is able to modify the threshold voltage, breakdown voltage, and on/off current ratio of the MSM diode in response to controlling the Si semiconductor layer thickness. Generally, both the threshold and breakdown voltage are increased in response to increasing the Si thickness. With respect to the on/off current ratio, there is an optimal thickness. The method is able to form an amorphous Si (a-Si) and polycrystalline Si (polySi) semiconductor layer using either chemical vapor deposition (CVD) or DC sputtering. The Si semiconductor can be doped with a Group V donor material, which decreases the threshold voltage and increases the breakdown voltage.
        • 提供了用于从硅(Si)半导体形成金属/半导体/金属(MSM)背对背肖特基二极管的方法。 该方法在底电极和顶电极之间沉积Si半导体层,并形成具有阈值电压,击穿电压和开/关电流比的MSM二极管。 响应于控制Si半导体层厚度,该方法能够修改MSM二极管的阈值电压,击穿电压和导通/截止电流比。 通常,响应于Si厚度的增加,阈值和击穿电压都增加。 关于开/关电流比,存在最佳厚度。 该方法能够使用化学气相沉积(CVD)或DC溅射形成非晶Si(a-Si)和多晶硅(polySi)半导体层。 Si半导体可以掺杂有V族施主材料,其降低阈值电压并增加击穿电压。
