摘要： Alpha particle detecting devices are disclosed that have a chamber that can hold a fluid in a tensioned metastable state. The chamber is tuned with a suitable fluid and tension such that alpha emitting materials such as radon and one or more of its decay products can be detected. The devices can be portable and can be placed in areas, such as rooms in dwellings or laboratories and used to measure radon in these areas, in situ and in real time. The disclosed detectors can detect radon at and below 4 pCi/L in air; also, at and below 4,000 pCi/L or 300 pCi/L in water. When the fluid is tensioned the presence of radon can be determined by the formation of bubbles which give off detectable signals including a shock wave, light-beam cutoff, or a light burst, any of which can be measured to derive information on radon and progeny radioactivity levels in air or water.

摘要： An easier and cheaper way to obtain multilayer circuit board is by using a flexible circuit board and folding it in an organized pattern. Flexible circuit has the unique property of being a three-dimensional circuit that can be shaped in multiplanar configurations, rigidized in specific areas, and molded to backer boards for specific applications. The folded circuit is fabricated from a series of foldable circuit board strips and rigid circuit board strips which are interconnected, folded, and bonded into a composite structure. The foldable strips may have prefolds arranged so that a group of upper foldable strips and lower foldable strips are folded in opposite directions. A plurality of intermediate portions are stacked on each other by the folding the foldable strips in opposite directions. The folded circuit, can be bonded after a first fold, or folded further to achieve a greater reduction in area and subsequently be bonded as a composite multilayer structure.

摘要： In gas detectors, such as may be used in computerized tomographic (CT) apparatus, it is necessary to provide electrical connections into the pressure vessel. Conventionally, these are by ceramic lead-throughs or similar. As gas detectors require an increasing number of individual detector elements, and therefore internal electrodes, the number of connections required increases and they are more closely spaced. This large number of connections can affect the integrity of the pressure vessel. This invention places a circuit board as a gasket between two parts of the pressure vessel, such as between a chamber and lid, so that conducting tracks on or in the circuit board provide the required connections. The invention is suitable for lead through for pressure vessels other than gas detectors of radiation.

摘要： A multicell x-ray detector includes a chamber for confining a gas that produces electron-ion pairs incidental to absorbing radiation. A unitary multicell electrode assembly is mounted within the chamber. The assembly includes a plurality of electrode plates secured in first and second insulating members. A method is provided for bonding the electrode plates into the insulating members with a uniform distribution of adhesive which does not allow the adhesive to bridge between adjacent plates. The opposed ends of the plurality of electrode plates are inserted into grooves of the members. A relatively non-viscous liquid adhesive is brought into contact with one edge of each of the grooves of both members by a cellular applicator until the adhesive propagates by capillary action along the entire length of each groove. The cellular applicator and the adhesive are such that the adhesive has a greater adhesive attraction to the applicator than to the adjacent plates, and such that the adhesive has a lesser adhesive attraction to the applicator than to the grooves of the members. The adhesive will therefore flow from the applicator to the grooves of each member until each groove is filled and any excessive adhesive will be attracted back to the applicator, rather than to the adjacent plates of the assembly. The adhesive is then cured.

摘要： An active detector and methods for detecting molecules, including large molecules such as proteins and oligonucleotides, at or near room temperature based on the generation of electrons via field emission (FE) and/or secondary electron emission (SEE). The detector comprises a semiconductor membrane having an external surface that is contacted by one or more molecules, and an internal surface having a thin metallic layer or other type of electron emitting layer. The kinetic energy of molecules contacting the semiconductor membrane is transferred through the membrane and induces the emission of electrons from the emitting layer. An electron detector, which optionally includes means for electron amplification, is positioned to detect the emitted electrons.
