A portable data collection device includes a FT-NIR spectrometer operable with a direct current (DC) power input, a hand-held probe having a large sampling area, a portable computer operable with a DC power input and configured for operation of the FT-NIR spectrometer; and a portable electric power source for providing a DC power output. The components of the portable data collection device are contained within a portable carrier. The portable data collection device is used onsite to obtain a spectra from a material sample. The spectra is sent by the portable computer of the portable data collection device to a remote computer/server. Application methods stored in a remote database analyze the spectra to obtain desired trait results for the material sample. The obtained results are stored on a remote database and can be displayed on a screen of an on-site mobile device.

In a method of measuring moisture in corn, an ear of corn is operatively coupled to a moisture meter and an amount of moisture is determined while the ear of corn is being grown on a corn plant. The moisture meter can use a spectrometry to determine the amount of moisture in the corn. A moisture meter includes a corn interface configured to conformingly engage the ear of corn when pressed against the ear of corn to form an optical seal about an opening through which the spectrometer determines the amount of moisture in the corn to inhibit ambient light from passing between the corn interface and the ear of corn into the at least one opening.

A characteristic of edible oil may be evaluated using a spectrometer. For example, optical reflectance data may be obtained from edible oil in situ in a frying apparatus housing the edible oil, the reflectance data corresponding to a specified range of infra-red wavelengths. A model profile corresponding to the characteristic being assessed may be obtained, such as from a repository housing a secured library of such profiles. The model profile may define a regression vector for use in transforming the reflectance data to generate a value corresponding to the characteristic being assessed. A criterion may be applied to the value to establish a simplified representation of the characteristic for presentation to a user for assessment of oil quality.

A portable culture test apparatus, comprising: a mounting portion on which a culture dish can be mounted; a vibrating portion that vibrates the mounting portion; a temperature adjusting mechanism that adjusts the temperature of the mounting portion; and an ultraviolet lamp that irradiates the culture dish mounted on the mounting portion with ultraviolet.

A Portable cannabidiol testing system which operates by selectively using specific visible wavelengths of light which are absorbed by the cannabidiol (CBD) chemical compound. The visible light spectrum source is tuned to wavelengths of light absorbed by the cannabidiol chemical compound. The testing system allows for verification of CBD content within a sample. The system utilizes a single use container with a premeasured reagent which allows for a reduction in the number of steps required for the testing process. An intrinsically safe light source and sensor are tuned to at least one specific wavelength of CBD light absorption and submerged in the CBD/Acetone reagent solution.

One aspect of the invention relates to a method for intraoperative assessment of parathyroid gland viability in a surgery. The method includes diffusing a beam of light onto a tissue surface of a parathyroid gland of a patient to illuminate the tissue surface; acquiring images of the illuminated tissue surface, where each of the acquired images includes a speckle pattern; and processing the acquired images to obtain speckle contrast images for the intraoperative assessment of parathyroid gland viability.

A system for measuring chlorophyll concentration in a leaf sample includes a leaf-holding illuminator device with a main body containing a power source, a plurality of switchable light sources emitting light at different spectra (e.g., red and white light from a broadband light source), and a cap detachably secured to the main body using one or more fastening means. The leaf sample is interposed between the main body and the cap and held in place during imaging. The system includes a mobile electronic device having a camera configured to capture an image of the leaf illuminated by the plurality of switchable light sources, the mobile electronic device having wireless connectivity to a network and an application contained therein configured to transfer the images to a remote sever or computer via the network for data processing. A final chlorophyll index value is calculated based on the transferred images.
