    • An implantable access port for use in transferring a fluid transdermally between an external fluid storage or dispensing device and a site within a patient's body is disclosed. The access port includes a base, a bowl-shaped reservoir defined within the base by a smooth surfaced wall, and a septum secured to the base and enclosing the reservoir within the base. The access port also includes a reservoir outlet defined centrally within the reservoir. The bowl-shaped reservoir is defined by a continuous smooth-surfaced curvilinear wall. The reservoir may thus be sized and shaped as a parabola, or may be hemispherical or semi-hemispherical in cross-section. The reservoir outlet is defined at a center point on the bottom of the reservoir wall, may be partially or fully recessed within the bottom of the reservoir wall, and is also defined in the base tangentially with respect to the bottom of the reservoir wall. The access port also has an outlet passageway defined within the base and extending in communication with the reservoir outlet and an external opening defined in the exterior of the base.

    • A serializer and a deserializer are disclosed and shown operating singly or as a pair. The invention operates independently from any outside system reference clock. The inventive system provides an internal bit clock that serializes the data when sending and de-serializes the data when receiving. A bit clock or pulse travels with the data word bits to define when a bit is stable. The system uses word boundary bits operating with a bit clock to distinguish different data words, as described in the parent application. The system operates either synchronously or asynchronously with the base computer or other such digital system, including I/O devices. The invention finds use where new data to be sent is strobed into the serializer, but also where a change in the data bit content itself will cause the changed data to be loaded into the serializer and sent bit by bit. The system operates where new data is strobed or loaded by the serializer (not the base computer system) when the last data word has been sent. In this case a signal is generated when the last word has been sent in the serializer that causes new data to be loaded for sending. Half duplex and full duplex configurations as disclosed. Similar, corresponding operations occur at the deserializer.
    • 串行器和解串器被公开并示出为单独操作或一对操作。 本发明独立于任何外部系统参考时钟工作。 本发明的系统提供内部位时钟,其在接收时发送和解串行化数据时串行化数据。 一个位时钟或脉冲随着数据字位移动,以定义位何时稳定。 系统使用以位时钟操作的字边界位来区分不同的数据字,如父应用程序所述。 该系统与基本计算机或其他此类数字系统(包括I / O设备)同步或异步运行。 本发明用于将要发送的新数据选通到串行器中,而且数据位内容本身的变化将导致改变的数据被加载到串行器中并逐位发送的地方。 当最后一个数据字被发送时,该系统在串行器(而不是基本计算机系统)选通或加载新数据的情况下运行。 在这种情况下,当序列化程序中发送最后一个单词时会产生一个信号,从而导致新的数据被加载发送。 所公开的半双工和全双工配置。 类似的,相应的操作发生在解串器。

    • The invention discloses a height adjusting apparatus for a vacuum cleaner nozzle, comprising: a barrel with a vertical passage, a groove module is formed on the inner surface of the barrel, said groove module comprises an upper groove, a lower groove, which has at least a first positioning point, a second positioning point differing from first positioning point in height and a intermediate point between the two positioning points; a resilient member, a lifting member, a driven member and a driving member are arranged in the passage of barrel from down to up. The height adjusting apparatus could be adjusted by applying a pressure force downwardly in vertical direction (for example, press by foot) and that takes less labor and time.
