Abstract: A method for liquefying gas involving pre-treating the gas stream in a pre-treater to remove impurities, and then passing the gas stream through a first flow path of a first heat exchanger to lower a temperature of the gas stream. The gas stream is then passed through the gas expansion turbine to lower a pressure of the gas stream and further decrease the temperature of the gas stream. The gas stream is then passed into a primary separator to separate the gas stream into a liquid stream and a cold gas stream. The liquid stream is collected. Selected quantities of the cold gas stream are passed through a second flow path of the first heat exchanger whereby a heat exchange takes place to cool the gas stream flowing through the first flow path to maintain the temperature of the gas stream entering the gas expansion turbine at a temperature which promotes the production of liquids.

Abstract: A dissipation-based sensor includes a single resonator with a nano-structured surface. The sensor exhibits improved sensitivity, up to about 2 orders of magnitude higher than a single resonator without a nano-structured surface. The sensor operates by measuring and estimating the fluid friction per oscillation cycle, operating in normal conditions without vacuum (e.g., in air or other ambient gas) at room temperature. The sensor can provide measurement data at a speed that is orders of magnitude faster than pre-existing resonance-based methods, as it is based on measurements from a few cycles only. The dissipation-based sensor may be utilized in a broad range of fast, inexpensive, hand-held measuring devices. Additionally, the sensor is capable of operating at standard temperature and pressure.

Abstract: A method and system for separating a suspension into solid and fluid components. The suspension is centrifuged about a substantially vertical axis of rotation to concentrate solid components in a first lower flow stream and fluid components in a first upper flow stream. The first upper flow stream may be centrifuged about a substantially vertical axis of rotation to concentrate solid components in a second lower flow stream and fluid components in a second upper flow stream. The first lower flow stream, the second lower flow stream, or both, may be centrifuged about a substantially horizontal axis of rotation to separate water from stackable dry tailings. The method and system may be applied to separation of tailings or other suspensions.

Abstract: An anti-distracted driving system comprises a plurality of transceivers at different locations within a vehicle. Each of the transceivers is operable to receive a signal from a mobile communication device and to output a detection signal indicative of the strength of the received signal. A controller in communication with the transceivers is operable to calculate a corresponding distance of the mobile communication device for each of the detection signals and to determine a location of the mobile communication device within the vehicle based on the distances. The controller can send a signal from a transceiver to a mobile communication device in response to determining that the mobile communication device is near a driver's seat, the signal causing at least one function of the mobile communication device to be inhibited.
