摘要:
A preservation system for storage and logistic transport of nutritional substances. The preservation system obtains information about the nutritional substance to be preserved, senses and measures the external environment to the preservation system, senses and measures the internal environment to the preservation system, senses and measures the state of the nutritional substance, and stores such information throughout the period of preservation. Using this accumulated information, the preservation system can measure, or estimate, changes in nutritional content (usually degradation) during the period of preservation. Additionally, the preservation system can use this information to dynamically modify the preservation system to minimize detrimental changes to the nutritional content of the nutritional substance, and in some cases actually improve the nutritional substance attributes.
摘要:
Device for moving a solid phase into a plurality of chambers, comprising a stationary component comprising a first guide structure, a first body comprising a second guide structure, and a second body comprising a third guide structure, the stationary component, the first body, and the second body being arranged along an axis, a plurality of chambers, a solid phase, and actuation means configured to exert a force, directed along the axis, on the first and second bodies so as to move the first and second bodies in a reciprocating manner along the axis in relation to the stationary component. The first, second and third guide structures are configured to cooperate, given a reciprocating movement of the first and second bodies in relation to the stationary component, so as to exert on the second body an adjusting force perpendicularly to the axis so as to cause a movement of the second body in relation to the first body and to the stationary component in a direction perpendicular to the axis. The solid phase or the plurality of chambers are mounted on the second body, the solid phase and the plurality of chambers being arranged, in relation to one another, such that by actuating the actuation means, the solid phase may be successively introduced into the chambers of the plurality of chambers.

The present invention relates to a logic gate, comprising a metamaterial surface enhanced Raman scattering (MetaSERS) sensor, comprising (a) alphabetical metamaterials in the form of split ring resonators operating in the wavelength range of from 560 to 2200 nm; and (b) a guanine (G) and thymine (T)-rich oligonucleotide that can, upon presence of potassium cations (K + ), fold into a G-quadruplex structure, and in presence of Hg 2+ , form a T-Hg 2+ -T hairpin complex that inhibits or disrupts the G-quadruplex structure formed in presence of K + , as well as methods of operating and using such a logic gate.
摘要:
A system and method for using near-infrared or short-wave infrared (SWIR) light sources between approximately 1.4-1.8 microns, 2-2.5 microns, 1.4-2.4 microns, 1-1.8 microns for active remote sensing or hyper-spectral imaging for detection of natural gas leaks or exploration sense the presence of hydro-carbon gases such as methane and ethane. Most hydro-carbons (gases, liquids and solids) exhibit spectral features in the SWIR, which may also coincide with atmospheric transmission windows (e.g., approximately 1.4-1.8 microns or 2-2.5 microns). Active remote sensing or hyper-spectral imaging systems may include a fiber-based super-continuum laser and a detection system and may reside on an aircraft, vehicle, handheld, or stationary platform. Super-continuum sources may emit light in the near-infrared or SWIR s. An imaging spectrometer or a gas-filter correlation radiometer may be used to identify substances or materials such as oil spills, geology and mineralogy, vegetation, greenhouse gases, construction materials, plastics, explosives, fertilizers, paints, or drugs.
摘要:
A system and method for assisting a user in assembling a culinary combination according to a recipe. The system comprises a scale and a computing device configured to communicate with the scale. The system displays information regarding ingredients of the recipe and displays a progress of assembling the culinary combination based on the information from the scale. In some embodiments, a bar graph is displayed with a bar proportional to the measured amount of an ingredient of the recipe compared to a target amount for the ingredient. In some embodiments, the system displays a build column of one or more recipe blocks, representing actions or ingredients of the recipe. An active recipe block is displayed with a portion of the recipe block displayed in a different manner in proportion to the measured amount of an ingredient of the recipe compared to a target amount for the ingredient.

A heat treatment monitoring system comprises a sensor unit having at least one sensor to determine current sensor data of food being heated; a processing unit to determine current feature data from the current sensor data; and a monitoring unit adapted to determine a current heating process state in a current heating process of the monitored food by comparing the current feature data with reference feature data of a reference heating process.
摘要:
A computer-implemented method of determining particle size and a computer-readable medium storing instructions to execute such a method are presented. The method entails obtaining an image of at least one particle and a calibration mark, wherein the particle and the calibration mark were captured using the same lens, correcting the image for distortion effects to generate a corrected image, wherein the same correction factor is applied to both the particle and the calibration mark, and determining a size of the particle using the corrected image. The method may be useful for obtaining the target size of coffee grounds that will produce the desired flavor. Coffee grounds may be sprinkled on a surface with the calibration mark and imaged with the calibration mark such that the correction factor for the calibration mark can be used to determine the particle size range of the coffee grounds.
