    • A self-destructing hypodermic device to allow one-time use only of the device. The device includes a syringe casing, a syringe tip, and a syringe plunger; all cooperating and functioning to allow solutions or medications to be drawn into the casing, and then intravenously injected into a user. At least some part or portion of the casing, plunger, and tip is comprised of a material which self destructs, at least partially, upon contact with the medication or solution intravenously injected, rendering the device unusable after one use. In one embodiment, the self-destructing portion of the casing, plunger, or tip is comprised of a material which is at least partially soluble in the medications or solutions intravenously injected by the device. Optionally, a tip cover can be used which can grip the syringe tip after use, to assist in disabilitating the device after one use.
    • 一种自毁式皮下注射装置,仅允许一次性使用该装置。 该装置包括注射器套管,注射器针头和注射器柱塞; 所有的合作和功能使溶液或药物被吸入套管,然后静脉注射到使用者中。 壳体,柱塞和尖端的至少一些部分或部分由至少部分地与静脉内注射的药物或溶液接触后自毁的材料组成,使得该装置在使用后不能使用。 在一个实施例中,套管,柱塞或尖端的自毁部分由至少部分可溶于由该装置静脉内注射的药物或溶液的材料组成。 可选地,可以使用尖端盖,其可以在使用后抓住注射器末端,以在一次使用之后帮助使装置失效。

    • A video timing display for multi-rate systems allows a user to quickly, easily and precisely measure the timing difference between video signals of different rates. A graphic display area within a raster display region provides a display of vertical and horizontal timing offsets of one video signal with respect to another video signal as a reference having a different frame rate. The graphic display area includes a reference indicator associated with the reference and timing indicators indicating the timing phases between the video signals, with one of the timing indicators being emphasized. A numeric display area may be provided adjacent the graphic display area to display the actual vertical and horizontal timing differences in appropriate units for the emphasized timing indicator relative to the reference indicator with a precision to one video clock cycle.
    • 用于多速率系统的视频定时显示允许用户快速,容易且精确地测量不同速率的视频信号之间的定时差。 光栅显示区域内的图形显示区域提供相对于作为具有不同帧速率的参考的另一视频信号的一个视频信号的垂直和水平定时偏移的显示。 图形显示区域包括与参考点相关联的参考指示符和指示视频信号之间的定时相位的定时指示器,其中一个定时指示器被强调。 可以在图形显示区域附近提供数字显示区域,以相对于参考指示器以适当的单位显示实际的垂直和水平时间差,以精确到一个视频时钟周期。

    • A curtain clip device (10) includes a top flange portion (14) with two inwardly directed channels (16) and (18) bounding of the upper surface (20) of the top flange portion (14). The inwardly directed channels (16) and (18) partially enclose the upper surface (20) of the top flange portion (14) to form a recess (24) sized to receive a support structure. A diagonally downward extending lever (26) protrudes from the outside lower corner of adjacent channel (18). Rotation of the lever (26) causes the top flange portion (14) to be flexed, allowing the clip device (10) to engage with a support structure. A curved lower jaw (30) depends downward from the lower surface (22) of the top flange portion (14) and has a free end (32) configured to form a jaw clasp (34). A stationary clasp (36) depends from the lower surface (22) of the top flange portion (14), which is designed to selectively mate in an interlocking configuration with the jaw clasp (34) of the curved lower jaw (30) thereby securing a protecting curtain. The curved lower jaw (30) further contains an outwardly directed channel (38) opposite the jaw clasp (34) for receiving a leverage tool to assist in unlatching the jaw clasp (34) from the stationary clasp (36).
    • 帘式夹具装置(10)包括具有两个向内指向的通道(16)的顶部凸缘部分(14)和与顶部凸缘部分(14)的上表面(20)相接合的顶部凸缘部分(14)。 向内定向的通道(16)和(18)部分地包围顶部凸缘部分(14)的上表面(20),以形成尺寸适于接收支撑结构的凹部(24)。 斜向下延伸的杆(26)从相邻通道(18)的外角突出。 杠杆(26)的旋转导致顶部凸缘部分(14)弯曲,允许夹子装置(10)与支撑结构接合。 弯曲的下颚(30)从顶部凸缘部分(14)的下表面(22)向下并且具有构造成形成颚夹(34)的自由端(32)。 固定的扣环(36)从顶部凸缘部分(14)的下表面(22)延伸,其被设计成选择性地与互锁构造配合地与弯曲的下颚(30)的夹爪(34)配合,从而固定 保护窗帘。 弯曲的下颌(30)还包含与钳爪(34)相对的向外指向的通道(38),用于接纳杠杆工具,以帮助将夹爪(34)从固定扣(36)上解锁。
