摘要： A method and apparatus for sensing a liquid-solid phase transition event is provided which comprises an acoustic plate mode detecting element placed in contact with a liquid or solid material which generates a high-frequency acoustic wave that is attenuated to an extent based on the physical state of the material is contact with the detecting element. The attenuation caused by the material in contact with the acoustic plate mode detecting element is used to determine the physical state of the material being detected. The method and device are particularly suited for detecting conditions such as the icing and deicing of wings of an aircraft. In another aspect of the present invention, a method is provided wherein the adhesion of a solid material to the detecting element can be measured using the apparatus of the invention.

摘要： A combustible gas sensor that uses a resistively heated, noble metal-coated, micromachined polycrystalline Si filament to calorimetrically detect the presence and concentration of combustible gases. The filaments tested to date are 2 .mu.m thick.times.10 .mu.m wide.times.100, 250, 500, or 1000 .mu.m-long polycrystalline Si; some are overcoated with a 0.25 .mu.m-thick protective CVD Si.sub.3 N.sub.4 layer. A thin catalytic Pt film was deposited by CVD from the precursor Pt(acac).sub.2 onto microfilaments resistively heated to approximately 500.degree. C.; Pt deposits only on the hot filament. Using a constant-resistance-mode feedback circuit, Pt-coated filaments operating at ca. 300.degree. C. (35 mW input power) respond linearly, in terms of the change in supply current required to maintain constant resistance (temperature), to H.sub.2 concentrations between 100 ppm and 1% in an 80/20 N.sub.2 /O.sub.2 mixture. Other catalytic materials can also be used.

摘要： The present invention discloses an electrochemical device for detecting single particles, and methods for using such a device to achieve high sensitivity for detecting particles such as bacteria, viruses, aggregates, immuno-complexes, molecules, or ionic species. The device provides for affinity-based electrochemical detection of particles with single-particle sensitivity. The disclosed device and methods are based on microelectrodes with surface-attached, affinity ligands (e.g., antibodies, combinatorial peptides, glycolipids) that bind selectively to some target particle species. The electrodes electrolyze chemical species present in the particle-containing solution, and particle interaction with a sensor element modulates its electrolytic activity. The devices may be used individually, employed as sensors, used in arrays for a single specific type of particle or for a range of particle types, or configured into arrays of sensors having both these attributes.

摘要： A method and system for automatically resolving a voice transmission problem in real time in a communication system. Service oriented architecture (SOA)-based reporter services report voice transmission characteristic measurements. An enterprise service bus aggregates the measurements into a combination of measurements. An analyzer that is a SOA service provider determines that the combination of measurements indicates a voice transmission problem. The voice transmission problem determination includes identifying a match between the combination of measurements and a pattern of predefined conditions stored in a database. The database associates the pattern with one or more corrective actions. Using the database, the analyzer identifies the one or more corrective actions that are associated with the pattern of predefined conditions. SOA-based fixer services execute the corrective action(s) to resolve the voice transmission problem. As new voice transmission problems become known, the system expands to add reporting services and fixer services.

摘要： A chemical-sensing apparatus is formed from the combination of a chemical preconcentrator which sorbs and concentrates particular volatile organic chemicals (VOCs) and one or more chemiresistors that sense the VOCs after the preconcentrator has been triggered to release them in concentrated form. Use of the preconcentrator and chemiresistor(s) in combination allows the VOCs to be detected at lower concentration than would be possible using the chemiresistor(s) alone and further allows measurements to be made in a variety of fluids, including liquids (e.g. groundwater). Additionally, the apparatus provides a new mode of operation for sensing VOCs based on the measurement of decay time constants, and a method for background correction to improve measurement precision.

摘要： A voltage booster device for increasing the voltage level of power received by a recreational vehicle (RV) from a separate 120-volt power source includes an electrical box, a power cord and female outlet on the box, and an encapsulated transformer within the box. The transformer (e.g., an autotransformer) is adapted to increase the actual voltage level of the separate 120-volt power source a predetermined amount. A relay is provided for switching the transformer, the power cord, and the female outlet between (i) a first circuit configuration that couples power from the power cord to the female outlet via the transformer so that the transformer increases the voltage level by the predetermined amount, and (ii) a second circuit configuration that bypasses the transformer so that the transformer does not increase the voltage level by the predetermined amount. A control circuit controls the relay so that (i) the relay switches to the first circuit configuration when the actual voltage of the separate 120-volt power source falls below a predetermined first threshold level, and (ii) the relay switches to the second circuit configuration when the actual voltage rises above a predetermined second threshold level. One embodiment includes a mounting plate with a rounded end that functions as a handle, and a case-hardened steel loop that receives a security chain.
