  • Patent number: 8309912
    Abstract: An ion trap instrument working at atmospheric pressure, which alleviates requirements of bulky, power consuming vacuum pumps. Traps can accumulate selected ion species, effectively concentrating the analyte of interest and allowing laser spectroscopy to be performed. This lowers the detection threshold of this instrument compared to others and increases the selectivity.

  • Patent number: 8297460
    Abstract: The vapor barrier for flammable liquid storage tanks provides a gas impermeable layer for covering the surface of a flammable liquid stored within a conventional flammable liquid storage tank, a tanker, a vessel or the like. The vapor barrier is formed from a plurality of spherical buoyant members. Each spherical buoyant member has a heat-resistant core or shell, a heat-reactive intumescent or flame retardant layer formed on an outer surface of the heat-resistant core, and an antistatic and oil-phobic layer formed on an outer surface of the heat-reactive intumescent layer. The vapor barrier may further be used with liquid storage tanks in which separation between the liquid and vapor phases is beneficial to prevent oxidation or other undesirable reactions.

  • Patent number: 8294116
    Abstract: Optical beam modulation is accomplished with the aid of a semiconductive nanomembrane, such as a silicon nanomembrane. A photocathode modulates a beam of charged particles that flow between the carbon nanotube emitter and the anode. A light source, or other source of electromagnetic radiation, supplies electromagnetic radiation that modulates the beam of charged particles. The beam of charged particles may be electrons, ions, or other charged particles. The electromagnetic radiation penetrates a silicon dioxide layer to reach the nanomembrane and varies the amount of available charge carriers within the nanomembrane, thereby changing the resistance of the nanomembrane. As the resistance of the nanomembrane changes, the amount of current flowing through the beam may also change.

  • Patent number: 8286440
    Abstract: According to one form of the invention, an auxiliary system is provided for supplying air conditioning to the cabin of a truck. The system includes an air conditioning compressor having a jackshaft mounted on a hub of the compressor. The system further includes an electric motor connected to the jackshaft by a belt for the motor, wherein the electric motor has a drive shaft and a pulley rigidly secured thereon, i.e., with no clutch and with no provision for slippage of the pulley relative to the drive shaft. The jackshaft has a pulley thereon for the electric motor drive. An end of the jackshaft that is not proximate to the compressor is rotatably held by a bearing and a bearing bracket in order to increase capability of the jackshaft to withstand side loading.

  • Patent number: 8283403
    Abstract: Carbon nanotubes (CNTs) are so long that they cannot be penetrated inbetween carbon fibers during a prepreg preparation process, and are shortened in order for them not to be filtered out by the carbon fibers. This results in a huge improvement of the mechanical properties (flexural strength and flexural modulus) compared with neat epoxy.

  • Patent number: 8245951
    Abstract: Use of carbon nanotubes (CNTs) in a charge injector to assist in atomizing fuel for engine applications. A CNT charging unit is positioned in front of a fuel injector. A voltage is applied on a CNT coated mesh to charge the fuel stream when it passes. Then the charged stream goes through a grounded metal cage. The fuel is thereby electrostatically charged causing repulsive forces on surfaces of liquid in the fuel resulting in the liquid splitting into droplets.

  • Patent number: 8242062
    Abstract: A method and composition for identifying chemically tagged petroleum products can be achieved by adding one or more chemicals to a selected petroleum product wherein the chemical is immune to extraction from the petroleum product by conventional inexpensive absorbents, cannot be removed by extraction with acids, bases, or immiscible solvents, cannot be easily oxidized, reduced or reacted with common agents, is difficult to disguise by masking with other agents, has a low polarity, and has a boiling point in the range of the petroleum products the chemical is being added to. The presence of the chemical is determined by using ion mobility spectroscopy.

  • Patent number: 8194845
    Abstract: A telephone and voice mail (voice processing) system is implemented using only a single processing means for controlling operations of both the telephone system and the voice mail system. The single processing means communicates with a hard disk, which stores programs for running the various operations of the system, voice prompts and all voice mail messages. The single processing means is coupled to signal processing circuitry, which emulates analog electronics that would be used for filters, tone decoder, generators, etc. The single processing means and signal processing circuitry are coupled to central office lines and station lines by a digital cross-point matrix, which can connect any voice path to another voice path. The system integrates call processing and voice processing into one system controlled by one set of software and a single processing means.

  • Patent number: 8129463
    Abstract: A combination of MWNTs (herein, MWNTs have more than 2 walls) and DWNTs significantly improves the mechanical properties of polymer nanocomposites. A small amount of DWNTs reinforcement (<1 wt. %) significantly improves the flexural strength of epoxy matrix nanocomposites. A same or similar amount of MWNTs reinforcement significantly improves the flexural modulus (stiffness) of epoxy matrix nanocomposites. Both flexural strength and flexural modulus of the MWNTs and DWNTs-coreinforced epoxy nanocomposites are further improved compared with same amount of either DWNTs or MWNTs-reinforced epoxy nanocomposites. In this epoxy/DWNTs/MWNTs nanocomposite system, SWNTs may also work instead of DWNTs. Besides epoxy, other thermoset polymers may also work.

  • Patent number: 8117894
    Abstract: A sensor system issues measurement commands at a predetermined regular rate. If a measurement indicates that a gas of interest is present, then the sensor system is signaled to wake-up thereby pulsing a heater for the sensor element that improves the accuracy of measurements. Measurements of humidity, temperature and gas concentration are made. If the gas of interest is detected then the data is used to indicate a compensated gas measurement. The gas level is classified as to its hazard and an adaptive detection algorithm is used to set an activity mode. If the gas of interest is not detected, the adaptive detection algorithm is used to set a sleep mode that saves power. Measurement rates are kept constant while heater power is controlled to reduce power consumption. Measurement rates are changed to increase concentration sensitivity.

  • Patent number: 8117897
    Abstract: An elliptical photo-acoustic spectrometer chamber design will result in a larger intensity signal at the pick-up microphone and allow high frequency light modulation. This makes the spectrometer have a lower limit of detection threshold, and will increase the signal to noise ratio in general for the instrument, resulting in a more sensitive instrument allowing more precise measurements.

  • Patent number: 7972859
    Abstract: A method of determining authenticity of an ingestible product purportedly from a batch of saccharide-marked ingestible product is provided. The ingestible product is a food, beverage, or pharmaceutical, for example. The method includes identifying a sample of the ingestible product to be tested; and testing the sample for a marked presence of the saccharide using a saccharide-specific binding protein. The ingestible product is not authentic when the testing demonstrates an unexpected change in the marked presence of the saccharide, and the ingestible product is authentic when the testing demonstrates no unexpected change in the marked presence of the saccharide.
