  • Patent number: 8363913
    Abstract: The present system and method provides a more precise way to record food and beverage intake than traditional methods. The present disclosure provides custom software for use in mobile computing devices that include a digital camera. Photos captured by mobile digital devices are analyzed with image processing and comparisons to certain databases to allow a user to discretely record foods eaten. Specifically, the user captures images of the meal or snack before and after eating. The foods pictured are identified. Image processing software may identify the food or provide choices for the user. Once a food is identified and volume of the food is estimated, nutrient databases are used for calculating final portion sizes and nutrient totals.

  • Patent number: 8349713
    Abstract: A system and method for enhancing the conversion efficiency of thin film photovoltaics. The thin film structure includes a photovoltaic absorbent layer covered by a confinement layer. A laser beam passes through the confinement layer and hits the photovoltaic absorbent layer. The laser can be pulsed to create localized rapid heating and cooling of the photovoltaic absorbent layer. The confinement layer confines the laser induced plasma plume creating a localized high-pressure condition for the photovoltaic absorbent layer. The laser beam can be scanned across specific regions of the thin film structure. The laser beam can be pulsed as a series of short pulses. The photovoltaic absorbent layer can be made of various materials including copper indium diselenide, gallium arsenide, and cadmium telluride. The photovoltaic absorbent layer can be sandwiched between a substrate and the confinement layer, and a molybdenum layer can be between the substrate and the photovoltaic absorbent layer.

  • Patent number: 8344319
    Abstract: The present disclosure provides a novel system and method for evaporating and ionizing compounds comprising an LIAD source and an ionization source that operates at atmospheric pressure. This system is readily adaptable for use with most commercially available mass spectrometers. Ionization sources include Atmospheric Pressure Chemical Ionization sources (APCI) and Atmospheric Pressure Photo Ionization (APPI) sources. The ionization sources are positioned such that the analyte desorbing from the surface of the LIAD is fed into the ion stream produced by the ionization source and ionized analyte and ionized fragments of the analyte are fed into the sample inlet of a mass spectrometer. These systems allow for the mass spectrometric analysis of non-polar compounds that lack readily ionizable functional groups, such as saturated and unsaturated hydrocarbons and compounds with medium to low polarity, as well as hydrocarbon mixtures, such as petroleum.

  • Patent number: 8334503
    Abstract: A method of controlling ion parking in an ion trap includes generating a trapping field for trapping cations and anions, and applying a tailored waveform during a period when ion/ion reactions occur to park first generation product ions with m/z values that differ from those of a cation and an anion in selected m/z regions.

  • Patent number: 8323364
    Abstract: A self-regulating on-demand gas generator. Generation of gas produced from a reaction is selectively, variably, and spontaneously controlled. A variable volume liquid chamber in communication with the pressure pot allows the volume of liquid reactant in the pressure pot to be varied. The amount of product gas generated in the pressure pot depends on the degree of contact between the solid-like reactant and the liquid reactant. The pressure of the product gas regulates the level of liquid in the pressure pot and thereby regulates the degree of contact between the solid-like reactant and the liquid reactant. A sealed gas chamber sharing a flexible diaphragm with the liquid chamber controls the expandability of the liquid chamber. Manipulating the pressure in the sealed gas chamber or the volume of the liquid reactant affects the pressure at which contact by the reactants will be initiated or terminated and thereby provides the ability to control the reaction.

  • Patent number: 8308926
    Abstract: This paper presents a microfluidic pumping approach using traveling-wave dielectrophoresis (tw-DEP) of microparticles. Flow is generated directly in the microfluidic devices by inducing electromechanical effects in the fluid using microelectrodes. The fluidic driving mechanisms due to the particle-fluid and particle-particle interactions under twDEP are analyzed, and the induced flow field is obtained from numerical simulations. Experimental measurements of the flow velocity in a prototype DEP micropumping device show satisfactory agreement with the numerical predications.
