    Abstract: A method and apparatus for stabilizing glow plasma discharges by suppressing the transition from glow-to-arc includes a perforated dielectric plate having an upper surface and a lower surface and a plurality of holes extending therethrough. The perforated dielectric plate is positioned over the cathode. Each of the holes acts as a separate active current limiting micro-channel that prevents the overall current density from increasing above the threshold for the glow-to-arc transition. This allows for a stable glow discharge to be maintained for a wide range of operating pressures (up to atmospheric pressures) and in a wide range of electric fields include DC and RF fields of varying strength.

    Abstract: A sterilization and decontamination system in which a non-thermal plasma discharge device is disposed upstream of a suspension media (e.g., a filter, electrostatic precipitator, carbon bed). The plasma discharge device generates a plasma that is emitted through apertures (e.g., capillaries or slits) in the primary dielectric. Plasma generated active sterilizing species when exposed to contaminants or undesirable particulate matter is able to deactivate or reduce such matter in contaminated fluid stream and/or on objects. Thus, the undesirable contaminants in the fluid to be treated are first reduced during their exposure to the plasma generated active sterilizing species in the plasma region of the discharge device. Furthermore, the plasma generated active sterilizing species are carried downstream to suspension media and upon contact therewith deactivate the contaminants collected on the suspension media itself. Advantageously, the suspension media may be cleansed in situ. To increase the sterilization efficicency an additive, free or carrier gas (e.g., alcohol, water, dry air) may be injected into the apertures defined in the primary dielectric. These additives increase the concentration of plasma generated active sterilizing agents while reducing the byproduct of generated undesirable ozone pollutants. Downstream of the filter the fluid stream may be further treated by being exposed to a catalyst media or additional suspension media to further reduce the amount of undesirable particulate matter.

    Abstract translation: 一种灭菌和去污系统，其中非热等离子体放电装置设置在悬浮介质（例如，过滤器，静电除尘器，碳床）的上游。 等离子体放电装置产生通过初级电介质中的孔（例如毛细管或狭缝）发射的等离子体。 当暴露于污染物或不期望的颗粒物质时，等离子体产生的活性灭菌物质能够使被污染的流体物流和/或物体上的物质失活或减少。 因此，待处理流体中的不期望的污染物在暴露于放电装置的等离子体区域中的等离子体产生的活性灭菌物质时首先被还原。 此外，等离子体产生的活性灭菌物质被运送到悬浮介质的下游，并且在与其接触时，使收集在悬浮介质本身上的污染物失活。 有利地，悬浮介质可以在原位清洁。 为了提高灭菌效率，可将添加剂，游离或载气（例如酒精，水，干燥空气）注入限定在初级电介质中的孔中。 这些添加剂增加等离子体生成的活性灭菌剂的浓度，同时减少产生的不期望的臭氧污染物的副产物。 在过滤器的下游，可以通过暴露于催化剂介质或另外的悬浮介质来进一步处理流体流，以进一步减少不期望的颗粒物质的量。

    Abstract: A large aperture, high spatial resolution vibration and acoustic sensing device is provided. The sensor is capable of directional resolution of acoustic sources in gaseous, liquid, and solid media, and can be employed as a directional microphone or a directional hydrophone. The sensor can also be used as a high-resolution vibration displacement sensor. The device is formed of thin films comprising two electret layers (25, 35) and a compliant intermediate layer (30) disposed therebetween. Conductive coatings (20, 37) disposed on the electret layers can be patterned and etched to provide a plurality of discrete sensing elements (40), forming a directional array. The sensor can be transparent, thereby allowing usage as a large area microphone disposed on top of a computer screen, video monitor, windows, or walls.

    Abstract: A device (10) which employs an acoustic signal having one or more frequencies for penetrating into ground, water, or sediments and vibrating a compliant buried object (8) is provided. When these acoustic signals encounter an acoustically compliant object (8) such as a mine, the acoustic signals vibrate the compliant object (8), leading to a vibration of the compliant object (8) against the boundaries of the surrounding medium such as ground sediment, creating a nonlinear distortion of the probing signal including the generation of harmonics and acoustic waves with combination frequencies (nonlinear signals). These nonlinear vibrating signals are received from the surface by a sensor (20). The amplitude of the measured nonlinear signals indicates the presence of an acoustically compliant object (8) such as a mine. The present invention also relates to a method and apparatus which emits an electromagnetic RF probing signal and acoustic or vibration signal (modulating signal), detects the reflected electromagnetic signal from the buried object (8), and processes the received signal, identifying the modulation caused by vibration.
