Abstract: A method and apparatus for stabilizing glow plasma discharges by suppressing the transition from glow-to-arc includes a perforated or apertured dielectric plate having an upper surface and a lower surface and one or more holes extending therethrough. The perforated dielectric plate (130) is positioned over the cathode (120). Each of the holes acts as a separate active current limiting microchannel 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 and in a wide range of electric fields include DC and RF fields of varying strength. In another embodiment, the device comprises an AC glow plasma discharge device wherein an apertured dielectric is placed over an electrode. The apertured dielectric may have one or more apertures or capillaries extending therethrough.

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 mid-infrared (MIR) and/or far-infrared (FIR) to near-infrared (NIR) converter (10) for imaging applications is disclosed. The converter (10) makes use of the properties of Optical Readout Quantum Well Infrared Photodetectors (OR­QWIP) (20), an NIR source (16), and a conventional near infrared detector device (24). In combination, an MIR or FIR light source (12) to be imaged is focused by lenses or mirrors (17) into a beam combiner (18) along with an NIR probe wave generated by the NIR source (16). The lower conduction level electrons (50a-50g) of the OR-QWIP (20) absorb MIR/FIR photons (60) and are excited to an upper conduction level (48) or free electron band (166) of the OR-QWIP (20) corresponding to the MIR/FIR wavelength (60), while valence band electrons (54a-54g) of the OR­QWIP (20) absorb NIR photons (52) and are excited to the freed-up lower conduction level (46) corresponding to the NIR wavelength (52). The resulting change in transmittance of NIR radiation due to absorption is recorded by conventional near infrared detection equipment such as a standard digital camera (24). If multiple layers (202a-202d) of AlGaAs are alternated with multiple layers (200a-200c) of GaAs of the same thickness and composition, then identical quantum wells (203, 223) will result, all of which absorb a single MIR/FIR wavelength and a single NIR wavelength. If multiple layers (246a-246d) of AIGaAs are alternated with multiple layers (244a-244c) of GaAs of different thicknesses and/or composition, then quantum wells (249, 259) having different energy level differences will result, the multiple quantum wells (249, 259) absorbing multiple MIR/FIR wavelengths (256a-256c, 264a-264c) and multiple NIR wavelengths (258a-258c, 270a, 270c).

Abstract: A method is disclosed for modifying an iterated block cipher by controlling the operations and transformations that cause diffusion. In one embodiment which is applicable to any iterated block cipher (12), a diffusion function (10), during encryption, is selected based on a parameter which measures the order of permutation of the diffusion function (10) and applies the diffusion function (10) to the encryption routine (12). The user chooses the required amount of diffusion for a given block of plaintext (11). The plaintext (11) is then encrypted using the modified diffusion function (10) to produce a ciphertext (14) which is then sent over a communications channel (16) which may be noisy. At the receiving end (18) of the communications channel (16), the received ciphertext (20), which now may be corrupted by bit errors, is passed through an iterated block cipher decryption routine (22) using the same diffusion function (10) selected earlier during encryption. In a second embodiment, the SCOPE method is applied to the DES encryption and decryption standard. The expansion bits (82) of DES are replaced with a minicipher (98a-98n), and the DES standard permutation box (88) is replaced with a permutation box (104a-104n) modified according to a user-specified order of permutation. In a third embodiment, the SCOPE method is applied to the AES encryption and decryptionstandard. In the SCOPE-enhanced version of AES, diffusion is controlled by altering the diffusion of the "MixColumn" or "InvMixColumn" transformations based on its branch number and by changing the number of shifts in the "ShiftRow" or "InvShiftRow" transformations.

Abstract: An apparatus is disclosed for permitting a mobile terminal having multiple, heterogeneous network connections (e.g., multiple wired or wireless transceivers of various types) to set up and maintain virtual connections over multiple networks to either the same or to multiple destinations. The mobile terminal can "load-share" traffic, i.e., it can distribute segments of traffic over a full set of heterogeneous networks, significantly improving the reliability and availability of communications. In a first embodiment, a mobile terminal is configured with multiple radio frequency (RF) transceivers. Operating system software is provided for dynamically establishing and maintaining traffic flow for user applications over multiple communications paths, and for automatically adapting to variations in the networking environment, application traffic flow requirements, end user preferences, or mobility. In a second embodiment, a software-defined radio is used to implement the physical layer protocols for each desired network, eliminating the need for multiple transceivers.

Abstract: An inventive sensor is used in combination with spectroscopic techniques to detect, identify and quantify ultratrace (ppt to ppb) quantities of analytes in air or water samples. The sensor preferably comprises a photonic crystal fiber having an air hole cladding with functionalized air holes. Surface-enhanced Raman spectroscopy is a preferred spectroscopic technique. In such applications, the air holes of the fiber may be functionalized by adsorbing a self-assembled monolayer on their inner surfaces, and immobilizing metallic nanoparticles to the monolayer. The invention has chemical and biomedical applications, and utility in detecting chemical and biological agents used in warfare.
