摘要： A compact plasma accelerator having components including a cathode electron source, an anodic ionizing gas source, and a magnetic field that is cusped. The components are held by an electrically insulating body having a central axis, a top axial end, and a bottom axial end. The cusped magnetic field is formed by a cylindrical magnet having an axis of rotation that is the same as the axis of rotation of the insulating body, and magnetized with opposite poles at its two axial ends; and an annular magnet coaxially surrounding the cylindrical magnet, magnetized with opposite poles at its two axial ends such that a top axial end has a magnetic polarity that is opposite to the magnetic polarity of a top axial end of the cylindrical magnet. The ionizing gas source is a tubular plenum that has been curved into a substantially annular shape, positioned above the top axial end of the annular magnet such that the plenum is centered in a ring-shaped cusp of the magnetic field generated by the magnets. The plenum has one or more capillary-like orifices spaced around its top such that an ionizing gas supplied through the plenum is sprayed through the one or more orifices. The plenum is electrically conductive and is positively charged relative to the cathode electron source such that the plenum functions as the anode; and the cathode is positioned above and radially outward relative to the plenum.

摘要： Automatic control system for controlling the switching point of a device which operates in at least two modes of operation, provides for automatic modification of the error signal which controls the switching action of the device by processing in real time the error signal to generate a resultant signal representative of the variation of the error signal over a time period, and then employing the resultant signal to modify the effect of the reference signal from which the error signal is derived. The control system can be employed in a chemical analysis instrument to control the on-off operation of a heater which supplies heated air to incubate samples.

摘要： A method and apparatus for testing a balanced diode mixer and local oscillator combination in a microwave receiver. The diodes comprising a balanced mixer are unbalanced in a selective, controlled manner to generate an offset signal. The unbalancing of the mixer is accomplished by heating one of a pair of mixer diodes. By measuring an offset voltage output of the balanced diode mixer after one of the diodes has been heated, it is possible to measure an artificially created diode mismatch offset voltage and thereby verify that the balanced mixer/oscillator combination is working properly. The heating step is performed by either forward biasing the mixer diode or by placing a resistive heating element adjacent to the diode.

摘要： The present invention relates to a method identifying relationships between professionals and other industry entities by assigning codes in categories and combining the codes to indicate a unique entity with discernable relationships. The method can be used to store information that describes different entities separately, while tracking relationships by applying alpha-numeric codes that identify a relationship when combined. The method creates and assigns codes to identify specific categories. The assigned codes from each category are combined in order to identify a specific entity by the relationship an individual has with other entities in other categories. Ultimately, a code can be identified for every unique relationship an individual professional has with other entities, including working relationships with other individuals.

摘要： A scabbard for holding a knife having a folding blade, the scabbard having means therein for engaging thumb slits in the blade of the knife while the knife is being removed from the scabbard to enable the user of the knife to pivot the blade to the open position as the knife is being withdrawn from the scabbard. The means for engaging the thumb slits in the blade can be two pins mounted in the side of the scabbard or two longitudinal ridges or springs extending from the inner walls of the scabbard to engage a substantial length of the thumb slit in the blade of the knife. In one embodiment of the invention, the conventional thumb slits of a folding knife are extended to the end of the portion of the knife blade which first contacts the means for engaging the knife blade to enable the thumb slits to be engaged by the ridges, springs, or pins in the scabbard.

摘要： The present invention is an apparatus and method for producing very large area and large volume plasmas. The invention utilizes electron cylcotron resonances in conjunction with permanent magnets to produce dense, uniform plasmas for long life ion thruster applications or for plasma processing applications such as etching, deposition, ion milling and ion implantation. The large area source is at least five times larger than the 12-inch wafers being processed to date. Its rectangular shape makes it easier to accommodate to materials processing than sources that are circular in shape. The source itself represents the largest ECR ion source built to date. It is electrodeless and does not utilize electromagnets to generate the ECR magnetic circuit, nor does it make use of windows.

摘要： A method and a device for detecting the breakage of glass. A glass breakage detector that uses an acoustic transducer, an analog-to-digital converter, and a processing means which uses software algorithms to determine if a signal received by the acoustic transducer is a result of glass breaking. The glass breakage detector also uses amplifiers which have a greater gain response for higher frequency components in the received signal. The glass breakage detector is also able to correct the offset error generated by the amplifiers. The processing means or digital signal processor (DSP) uses a feature extraction software algorithm that extracts characteristics of the received sound using a plurality of filters centered at different frequencies and a rules analysis software algorithm to compare the extracted features to features from glass breakage and false alarms. The DSP is also capable of transmitting the extracted features to an external computing device for further analysis. The DSP may use different software routines which may be selected by a user to process the signal from the acoustic transducer. The software algorithms used by the DSP may be modified or customized for optimally detecting a glass breakage event.
