A method of unambiguous identification and authentication of products for the purpose of better recognition of product forgeries and controlling product piracy, including applying to/into the product an identification substance admixture which contains paramagnetic phases or identifying a product which contains an identification substance admixture containing paramagnetic phases and has an ESR fingerprint spectrum that permits unambiguous identification of the product. Such an ESR fingerprint spectrum is easily measurable, but can be copied or forged only with difficulty. The method relates to an individualizable 'femto tag' for femto ledgers and forms an important interface for what are known as “Internet of Things” (IOT).

Unique identification and authentication of products

A process prepares a polymer powder, with a D50 particle size from 40 to 200 &#x3bc;m and a Hausner factor of 1.25 or less, by freeze drying and subsequent loosening up of an aqueous polymer dispersion containing 15 to 50% by weight of a polymer. The polymer is polymerized from 10 to 30% by weight of methyl methacrylate, 50 to 70% by weight of methyl acrylate, and 5 to 15% by weight of methacrylic acid.

Process for preparing a polymer powder

The invention relates to a device with a sensor arrangement, which is able to detect magnetic or magnetized oral administration forms after oral take-up, moreover tracks the dissolution thereof via the reduction or disappearance of the magnetic field of the oral administration form, and with a log function, which records a subjective evaluation on the part of the human wearer of the sensor arrangement during or after the oral take-up.

Personalized detection system for detecting magnetic objects in the human organism

The subject matter of the invention is a detector system for detecting magnetic bodies in the human organism, which comprises at least two sensor assemblies, wherein each sensor assembly has one, two or three anisotropic magnetic resistance sensors, of which the axes of weak magnetization point in different directions in pairs, and each sensor assembly has a spacing of 0.5 to 50 cm from the sensor assembly or the other sensor assemblies, and at least two sensor assemblies are tilted at an angle of 0 to 45&#xb0; with respect to one another, and in addition a method for detecting the magnetic flux produced by a magnetic body in the human organism, and the use of the detector system according to the invention for detecting swallowed magnetic bodies and the disintegration of the same in the digestive system.
