  • Publication number: 20200075134
    Abstract: The present invention provides a method and a device for estimating a value to be estimated associated with a specimen, by performing machine learning of a relationship between a value of an estimation object and an output corresponding thereto, based on an output from a chemical sensor with regard to a plurality of specimens for which specific values to be estimated are known, and using the result of the mechanical learning to estimate a specific value to be estimated on the basis of an output from the chemical sensor with regard to a given unknown specimen.

  • Patent number: 10564082
    Abstract: According to improvement of the receptor layer of various sensors of the type for detecting physical parameters (for example, a surface stress sensor, QCM, and SPR), all of high sensitivity, selectivity, and durability are achieved simultaneously. A porous material or a particulate material, e.g., nanoparticles, is used in place of a uniform membrane which has been conventionally used as a receptor layer. Accordingly, the sensitivity can be controlled by changing the membrane thickness of the receptor layer, the selectivity can be controlled by changing a surface modifying group to be fixed on the porous material or particulate material, and the durability can be controlled by changing the composition and surface properties of the porous material or particulate material.

  • Patent number: 10458939
    Abstract: As a receptor layer, a film of a composite material of a base material such as a polymer and particles that adsorb an analyte is used. When the present invention is applied to a surface stress sensor or the like, the Young's modulus of the receptor layer, which significantly affects detection sensitivity, can be preset with a high degree of freedom, by independently selecting particles that adsorb a desired analyte and a base material that disperses said particles therein.

  • Publication number: 20190323982
    Abstract: The invention provides: a gas sensor device that is capable of removing a component adsorbed on a gas sensor by relatively simple means and easily restoring a signal baseline of the gas sensor to a constant state; and a method for removing a gas component. The gas sensor device according to an embodiment of the invention includes a gas sensor and cleaning means that contains a liquid for cleaning the gas sensor. The gas sensor includes a sensor main body that is capable of detecting a characteristic parameter of a component present in a gas phase or a liquid phase, and a sensitive membrane that is coated on a surface of the sensor main body and is durable against the liquid.

  • Publication number: 20190320291
    Abstract: A system for privacy protection includes a processor and a terminal including a location detection device. The processor performs: identifying a presence possible ranges of the terminal at a first time and at a second time earlier than the first time from a combination of information on a first region including the location at the first time, and information on a second region including the location at the second time and having been already transmitted to an external apparatus; determining whether each of the identified presence possible ranges satisfies a preset condition for a presence possible range that may be known by a third party; when the condition is not satisfied, transmitting the information on a third region including the first region and a region other than the first region, as information on a region where the terminal is present at the first time, to the external apparatus.

  • Patent number: 10444133
    Abstract: A sample in a gas state to be measured is forced to impinge on a structure in which a change in a characteristic including a mechanical deformation, an optical change, an electric change and a magnetic change is exerted due to the impingement of a gaseous sample, a gasified liquid sample or solid sample to cause at least one of changes in characteristics including a mechanical deformation, an optical change, an electric change and a magnetic change; and the molecular weight of the sample in a gas state is obtained.

  • Publication number: 20180356388
    Abstract: Provided is a sensor which enables detection/identification of various types of fuels for automobiles by using simple devices. According to the present invention, high-octane gas, regular gas, diesel oil, heating oil, gasoline laced with heating oil, and the like can be clearly identified without using a large-scale analysis such as gas chromatography or mass spectroscopy by using a sensor having a structure in which a surface of a sensor body which detects a surface stress or the like is coated with particles modified with a hydrocarbon group such as an alkyl group.
