    • A current is injected in the vicinity of a liquid-containment facility of interest to create a measurable electrical potential field in the ground underlying the site. Voltage is measured at each of a plurality of electrodes and plotted as a function of time. The rate of change of the voltages measured at each electrode was found to be proportional to the flow rate of any leak from the facility. Accordingly, the monitoring system is calibrated with artificially imposed leaks flowing at various rates and the resulting information is used to estimate the flow rate of actual leaks on the basis of the slope of the potential plot recorded by any given electrode over time. In the preferred embodiment of the invention, the flow rates so calculated are averaged to produce an estimate of the rate of leakage.
    • 将电流注入感兴趣的液体容纳设施附近,以在场地下方的地面上产生可测量的电势场。 在多个电极中的每一个处测量电压并作为时间的函数绘制。 发现在每个电极处测量的电压的变化率与设备的任何泄漏的流量成比例。 因此,监测系统被以人为地施加的以不同速率流动的泄漏进行校准,并且所得到的信息用于基于任何给定电极随时间记录的电位图的斜率来估计实际泄漏的流量。 在本发明的优选实施例中,如此计算的流量被平均以产生泄漏速率的估计。

    • Methods and devices are provided for aerosolizing medicament to be inhaled by a user. A housing is provided with an aerosol generator contained within the housing. A medicament feed system supplies medicament to the aerosol generator. A mouthpiece has separate medicament and air flow passages. The medicament flow passage provides aerosolized medicament from the aerosol generator to an outlet of the medicament flow passage, and the air flow passage has an inlet in fluid communication with an ambient atmosphere. The outlets of the medicament and air flow passages are provided at an end of the mouthpiece to provide simultaneous flows of medicament and air that mix in the user's mouth upon inhalation by the user at the end of the mouthpiece.
