    • Methods and apparatus for enhancing an inflatable device. In one example, a first component adapted to generate at least one of light and sound is coupled to a second component that is adapted to facilitate insertion into an inflatable device. The first component may be an LED-based light source configured to generate single or multi-colored light in an interior space of the inflatable device once inserted into the inflatable device. The second component may be particularly configured with one or more valves or seals to facilitate a transfer of a substance (e.g., an inflating substance) into the inflatable device once the first and second components are inserted into the inflatable device. The second component also may be configured to conveniently facilitate an effective seal between the second component and the inflatable device.
    • 用于增强充气装置的方法和装置。 在一个示例中,适于产生光和声音中的至少一个的第一部件耦合到适于便于插入到可充气装置中的第二部件。 第一部件可以是被配置为一旦插入到可充气装置中时在可充气装置的内部空间中产生单色或多色光的基于LED的光源。 一旦第一和第二部件被插入到可充气装置中,第二部件可以特别地配置有一个或多个阀或密封件,以促进物质(例如充气物质)转移到充气装置中。 第二部件还可以被配置为方便地促进第二部件和可充气装置之间的有效密封。

    • An improved SCUBA diving gauge. A pictograph display is provided which has a shape which conveys the type of information being displayed. The pictograph has the shape of a SCUBA tank for a tank pressure display and the shape of a person for a display of nitrogen absorbed. Pressure transducers coupled to the SCUBA tank and the external water provided the pressure readings required to produce the respective displays. The differential signal from the transducer is supplied to a processor through an auto-zeroing circuit. The auto-zeroing circuit uses a capacitor initially coupled to an amplifier reference input and single ended output to store an offset voltage. During a measurement, the capacitor is disconnected from the amplifier output and has its other lead coupled to a full scale value of the differential input to produce an output signal which is a ratio.
    • 改进的SCUBA潜水表。 提供了一种象形文字显示器,其具有传送正在显示的信息类型的形状。 象形图具有用于罐压显示器的SCUBA罐的形状和用于显示氮气吸收的人的形状。 耦合到SCUBA罐和外部水的压力传感器提供产生相应显示器所需的压力读数。 来自传感器的差分信号通过自动归零电路提供给处理器。 自动调零电路使用最初耦合到放大器参考输入和单端输出的电容器来存储偏移电压。 在测量期间,电容器与放大器输出端断开,并且其另一个引线与差分输入的满量程值相连,以产生一个比例的输出信号。
