  • Patent number: 11982567
    Abstract: A light field relay has an array of microlenses, an array of transducers, and an array of output optics. Microlenses focus one or more than one selected portions of an incident light field to separate corresponding transducers. Each corresponding transducer receives and transduces a single portion of focused light and emits the transduced light. Corresponding different output optics substantially collimate the transduced light and emit the substantially collimated light as an emitted light field. The light field relay may collect infrared light in one or more selected portions of an incident light field, transduce the infrared light to visible light, substantially collimate the transduced visible light, and emit a visible light field.

  • Patent number: 11828739
    Abstract: A method and system for sample analysis involve a temporally-resolving separation of sample components. In the method, solvent vapors are condensed prior to entering a temporally-resolving separator, a GC column, for example, and solvent-depleted vapors are directed to the separator where constituents are resolved in time. A system for analyzing a sample comprises an injection port, a temporally-resolving separator (e.g., a GC column) and a conduit connecting the two. The injection port is at a temperature sufficiently high to vaporize the solvent and analytes present in a sample. The conduit is configured and/or operated to condense the solvent, while maintaining the analytes in the vapor phase.

  • Patent number: 9983130
    Abstract: The invention described herein relates to a method of detecting malaria comprising the steps of: (i) delivering an evanescent IR beam through said ATR substrate in contact with a patient blood sample; (ii) detecting IR radiation transmitted from the ATR substrate to produce a signal characteristic for one or more lipids in the sample, and (iii) processing said signal and a set of reference library spectra of lipids associated with malaria parasites in order to detect matches and quantify said one or more lipids in the sample. In contrast to the prior art, the present invention relies on detecting lipids instead of hemozoin.

  • Patent number: 9962647
    Abstract: This invention provides a zero gas refiner for CO2 concentration measurement device that can continuously refine a zero gas that is preferable for CO2 concentration measurement. This invention adopts the zero gas refiner comprising a water adsorbent and a CO2 adsorbent that desorb an adsorbed component and restore an adsorption ability by being heated to a predetermined restoration temperature, a refiner body that adsorbs water and CO2 in an introduced sample gas or air in this order by the use of the water adsorbent and the CO2 adsorbent housed inside of the refiner body so as to refine a zero gas and that leads out the zero gas, and a heating mechanism that applies heat to the refiner body at a time when the adsorption ability of the water adsorbent or the CO2 adsorbent drops to an amount that is less than or equal to a predetermined amount.

  • Patent number: 9922407
    Abstract: The invention relates to a method for analyzing a multispectral image (10), which includes designing a detection image from signal-to-noise ratio values. The signal-to-noise ratio values relate to the content of the multispectral image inside a window which is determined around each pixel, when the contrast in the window is maximized by a Fischer projection. The signal-to-noise ratio values at calculated from integral images of order one and two, which in turn are calculated only once initially, so that the total amount of calculations is reduced. The analysis method is compatible with a real-time implementation during a capture of consecutive multispectral images which form a video stream, in particular for an environment-monitoring task.

  • Patent number: 9910014
    Abstract: A method for the detection of a gas flowing from a location in a structure is described. A hollow-core optical fiber is placed in a position adjacent the structure. The fiber includes a sound-conductive cladding layer; and further includes at least one aperture extending into its cross-sectional diameter. A beam of pulsed, optical is transmitted into the fiber with a tunable laser. The optical energy is characterized by a wavelength that can be absorbed by the gas that flows into the fiber through the aperture. This causes a temperature fluctuation in the region of gas absorption, which in turn generates an acoustic wave in the absorption region. The acoustic wave travels through the cladding layer, and can be detected with a microphone, so as to provide the location of gas flow, based on the recorded position and movement of the acoustic wave. A related system is also described.
