摘要： In a wireless sound monitoring system, ambient sounds are monitored by a microphone and transmitted over a phase or frequency modulated transmitter to a receiver. A sound actuated switch responsive to ambient sounds louder than a predetermined level turns the transmitter on and causes a hidden tone to be generated. A delay circuit caused the hidden tone to be terminated before the transmitter is turned off when the sound level decreases. In the receiver, a mute circuit responds to the hidden tone to control the output of a loudspeaker, and thus, the hidden tone prevents a squelch tail from being heard. The monitoring unit also includes a pulse generator to cause the hidden tones to be generated at regular intervals, but with short pulse widths. In the receiver, a mute delay circuit prevents the un-muting of the loudspeaker in response to these short pulses, but as long as the hidden tone pulses are detected within a predetermined period of time, a visual indicator, an LED, will light to show the proper operation of the system. Each hidden tone detected will cause the LED to blink momentarily; however, if the hidden tones are not detected, the LED will be extinguished and a distinctive audio tone will be generated to alert the user.
摘要翻译：在无线声音监测系统中，环境声音由麦克风监测并通过相位或频率调制的发射机传输到接收机。响应于比预定水平更大的环境声音的声音致动开关使发射机接通并且产生隐藏的音调。当声级降低时，延迟电路在发射机关闭之前导致隐藏音被终止。在接收机中，静音电路响应隐藏音调以控制扬声器的输出，因此，隐藏的音调防止了静音尾部被听到。监视单元还包括脉冲发生器，以使得隐藏的音调以规则的间隔产生，但具有短的脉冲宽度。在接收机中，静音延迟电路可以防止响应于这些短脉冲的扬声器的静音，但是只要在预定的时间段内检测到隐藏的音调脉冲，则视觉指示器LED将会点亮到显示系统的正常运行。检测到的每个隐藏音都会导致LED瞬间闪烁; 然而，如果未检测到隐藏音，则LED将熄灭，并且将产生独特的音频音来提醒用户。

摘要： A device for producing bubbles is disclosed including a housing having an entry port and an exit port, where a chamber is defined therein in flow communication with the entry and exit ports. A drive shaft is located within the housing chamber with a turbine wheel mounted to the drive shaft in a rotatable manner. The turbine wheel includes a plurality of pin members extending therefrom and a crank arm is provided for rotating the turbine wheel. Accordingly, water and bubble solution entering the housing chamber through the entry port is mixed with air to produce bubbles in the housing chamber which are encouraged to flow through the exit port. The entry port is oriented substantially perpendicular to the rotation of the turbine wheel and the exit port is oriented substantially in line with the rotation of the turbine wheel.
摘要翻译：公开了一种用于产生气泡的装置，包括具有入口和出口的壳体，其中限定了与入口和出口流体连通的腔室。驱动轴位于壳体室内，涡轮机轮以可旋转的方式安装到驱动轴上。涡轮机叶轮包括从其延伸的多个销构件，并且设置有用于旋转涡轮机叶轮的曲柄臂。因此，通过入口进入容纳室的水和泡沫溶液与空气混合以在壳体室中产生鼓泡流过出口的气泡。入口端口基本上垂直于涡轮机叶轮的旋转定向，并且出口端口基本上与涡轮机叶轮的旋转一致。

摘要： An infant seat having a seating surface positionable between upright and reclined orientations, the seating surface being supported by arms which are connected to torsion springs in a base, the torsion springs providing a bouncing motion to the seating surface in both the upright and reclined orientations. The base includes a rear support member which pivots between a support position, in which the member is substantially coplanar with the base, and a collapsed or folded position, in which the support member is pivoted adjacent to the seating surface. In a preferred embodiment, the connection between the seating surface and support arms includes a pivot plate pivotally connected to the seating surface and support arms and includes a slot engaged by a shoulder rivet attached to the support arms which defines limits of pivotal movement of the seating surface. The rear support member preferably includes nock fittings at its ends which engage the torsion springs and are held in engagement by extension springs captured within the rear support member ends. When the infant seat is adjusted to the collapsed or folded position, the nock fittings are disengaged from the torsion springs and pivoted toward the seating surface.
