Abstract: A display unit is controlled so that a plurality of parameter setting screens respectively corresponding to a plurality of steps sequentially executed in a predetermined order in quantitation is sequentially displayed and a plurality of step indexes respectively corresponding to the plurality of steps is displayed. In a plurality of parameter setting screens, inputting of a plurality of parameters respectively corresponding to the plurality of steps is received. Each time inputting of parameters in each parameter setting screen is completed, the received parameters are set in an unchangeable manner. The display unit is controlled so that each time parameters are set in one parameter setting screen, the next parameter setting screen is displayed, and the step index corresponding to the displayed parameter setting screen which is being displayed among the plurality of step indexes is displayed in such a manner as to be distinguishable from the other step indexes. A spectrophotometer is controlled based on the set parameters. The sample is quantified by a quantitative execution unit based on the set plurality of parameters.

Abstract: Provided is a reliable or accurate optical detection method or such an optical imaging method. Also provided is an application technique using such a method. At least a part of an optical path starting from a light-emitting source or reaching a photodetector includes a plurality of optical paths. At a predetermined position of the optical path, beams of light after passing through the plurality of optical paths are mixed. This mixed light is used for optical detection or optical imaging. An optical-length difference among beams of light passing through the plurality of optical paths may be longer than the coherence length. Means for feed-backing predetermined characteristics of a target to the optical characteristics to be used for optical detection or optical imaging may be included. Such means may be used separately from the above. Such means may be applied to another technique, an application material or an application program.

Abstract: Systems and methods for color selection are provided. A web server stores a lookup table that associates room types and types of feelings with paint colors such that each possible combination of room type and type of feeling is associated with a subset of paint colors. A user device displays the room types, receives a room type selection indicating a particular room type, displays the types of feelings, receives a type of feeling selection indicating a particular type of feeling, accesses the lookup table and determines the associated subset of paint colors in the lookup table for the combination of the particular room type and the particular type of feeling, and displays the associated subset of paint colors as recommended paint colors for the combination of the particular room type and the particular type of feeling on the display of the user device.

Abstract: A small scale and low cost spectral sensing system designed primarily for multi-component fluids that provides a compact, low cost platform for analyzers or chemical sensors with limited number of optical and mechanical components featuring a light source, an optical interface with the sample, and a custom detector (multi-element). A single detector element has a specific wavelength, defined by a filter that can be used to select and measure specific chemical compounds. Multiple detector elements are combined to create a multi-channel detector capable of measuring a broad range of wavelengths from ultraviolet (UV) to near and mid-infrared wavelengths. The fabricated sensor can be configured for almost any class of material including gases, vapors, and liquids, with extension to solids. This is linked to the use of the custom detectors featuring filters tailored to specific substances in a broad spectral range from the UV to infrared.

Abstract: A receiver receives a wide band signal in a range comprising a front end to the receiver including a complementary metal-oxide-semiconductor (CMOS). The CMOS includes a dipole antenna that receives a received signal; a hybrid-based broadband isolation structure that receives the received signal and a local oscillator LO signal and passes through the LO signal to a sub-harmonic mixer. The sub-harmonic mixer mixes the received signal with the local oscillator signal to generate an intermediate frequency (IF) signal to the hybrid-based broadband isolation structure.

Abstract: A method for colorimetric detection of cholesterol in a sample is disclosed. The method includes adding beta-cyclodextrin and cholesterol to a phenolphthalein indicator solution in the presence of a phosphate buffer solution to create a solution medium and quantifying the cholesterol as a function of a complexed beta-cyclodextrin in the solution medium.

Abstract: There is provided a detector, and a method of calibrating or correcting a detection value in a wavelength range within an evaluable range by using a detection value in a wavelength range other than the evaluable range by using the detector. The detector includes an active layer containing a quantum well or quantum dots, and that is capable of sweeping a detection peak wavelength of a detection spectrum in a wavelength range within an evaluable range and a wavelength range other than the evaluable range, and is configured to correct or calibrate a detection value in the wavelength range within the evaluable range using a detection value in the wavelength range other than the evaluable range.

Abstract: The present inventors have developed a ground station that, when installed in a field, can collect upwelling and downwelling radiation, and GPS location coordinates, Data from remotely sensed imagery (RSI) can be used to monitor crop health. Use of the ground station can obviate the need for personnel to be deployed into the field during drone overflights for management of agriculture.
