    • A novel method is disclosed for detecting and controlling the flow rate of a perturbed, droplet-forming stream in an electrostatic particle sorting apparatus. Detection apparatus is located at two points along the stream, at a first particle sensing point for sensing the presence of particles within a core portion of the stream, and at a second downstream point, preferably the stream breakpoint, for sensing light scatter and extinction characteristics which are proportional to the surface characteristics of the sheath portion of the stream. Changes in phase shift, pulse width, duty cycle, pulse area, or breakpoint location are detected by analyzing these sheath surface-related characteristics. An error signal is produced in response to such changes which drives an electromechanical fluid flow regulator to increase or decrease the fluid flow rate in a direction which tends to minimize the error signal. The flow rate is thus maintained at a reference flow rate setting.

    • In order to initiate the charging of droplets at a specific point in time with respect to the formation of those droplets in an electrostatic flow sorting system, the charge phase of the system of the present invention is continuously and automatically adjusted by droplet break point monitoring. The charge phase is therefore flow rate and fluid velocity independent. The break point is monitored by a light source which is focused onto the jet stream at the droplet formation break point, or close to it, and the modulation of light caused by the scatter induced by the sheath stream portion as it passes the focused beam of light is detected via the use of a suitable electro-optical detector. From the output of the electro-optical detector, after appropriate signal conditioning, an electrical wave form is obtained which shape depends upon the shape of the fluid column passing the focus beam. Using this conditioned detector output, the charge pulse phase is automatically controlled to occur at a set point in time with respect to a transition point on the waveform thus obtained. Additionally, in order to compensate for large flow rate variations, the focused beam detector can be automatically repositioned to track with the breakpoint. The correct phase of the charge pulse will accordingly continue to be derived from the breakpoint electrical waveform. Alternatively, by monitoring the jet stream at points above or below the breakpoint, the phase adjustment is possible, however, somewhat fluid velocity dependent.
    • 为了在静电流分选系统中相对于形成这些液滴的特定时间点开始液滴的充电,本发明的系统的充电阶段通过液滴断点监控连续自动调节。 因此,充电阶段是流速和流体速度无关。 断点由在源于液滴形成断裂点或靠近喷射流的聚焦到射流上的光源监测,并且由鞘流部分引起的散射引起的光的调制,当它穿过聚焦束 通过使用合适的电光检测器检测光。 从电光检测器的输出,在适当的信号调节之后,获得电波形式,其形状取决于通过聚焦光束的流体柱的形状。 使用该调节的检测器输出,充电脉冲相位被自动控制在相对于如此获得的波形上的转变点的设定时间点发生。 另外,为了补偿大的流量变化,聚焦光束检测器可以被自动重新定位以跟踪断点。 因此,充电脉冲的正确相位将继续从断点电波形导出。 或者,通过在断点上方或下方的点监测喷射流,相位调整是可能的,然而,稍微流体速度依赖。

    • A novel method for positioning the point of droplet formation in the jetting fluid of an electrostatic sorting device is disclosed. The formation of the uniform droplets is carried out via the application of vibrational energy inparted by a transducer to a jetting laminar flow stream. Previously sensed particles contained within the core portion of the laminar stream are subsequently sorted from the stream as part of a subsequently formed droplet. The disclosed method uses the dependency of the droplet formation point on the amplitude of the wave form applied to the transducer and the modulation of this amplitude to control the droplet formation point distance. The position of the droplet formation point is detected via the use of a light source and photodetector focused on the jetting stream at the position at which the droplet formation point is to be located, and a method for automatically maintaining the breakpoint at that position is described.

    • A child/dependent care system provides a way for parents (or other responsible individuals) to remotely observe and communicate with their children (or dependents or other charges) at a care center. The system includes a video link between the care center, or "activity area," and one or more remote areas disposed remotely from the care center. Each video link includes a video camera and monitor, permitting the parent to see his or her charge at the care center, and vice versa. The system can also include a telephone link between the sites, permitting voice communication between the parent and the charge. Still further, the system can provide a paging link, whereby an adult supervisor at the center can page the parent and alert him or her to contact the center e.g., via phone. A lock-out can also be provided to insure that only authorized parents can view charges at the care center.
