Abstract: An example operation may include one or more of executing, by an endorser node, a smart contract to generate a blockchain transaction data, generating, by the endorser node, metadata specific to the endorser node, concatenating, by the endorser node, the metadata with the blockchain transaction data, signing, by the endorser node, a concatenation result data with a key of the endorser node, and providing, by the endorser node, the signed concatenation result data to a committer node for verification.

Abstract: A wetness or saturation and temperature, and motion, and posture or orientation detecting distributed system that can include a wireless module, a wireless hub and a local or cloud server. A distributed algorithm that is stored and executed in the wireless module and the wireless hub or cloud or local server can detect wetness or saturation of the undergarment and temperature, and motion, and posture or orientation of the wearer and can also automatically count the number of undergarment changes performed daily by the caregivers.

Abstract: A wetness or saturation and temperature, and motion, posture or orientation detecting system in an undergarment. A wireless module can comprise a housing, a cover, and a controller. The controller can comprise environmental sensors, a motion analyzer, and a memory medium. The environmental sensors can be a temperature sensor, a humidity sensor, a pressure sensor that can monitor and detect environmental conditions surrounding it within the undergarment or other article of clothing. The wireless module can further comprise a microcontroller unit (“MCU”) and a communications module. The cover can have a thru hole substantially positioned over the environmental sensor wherein the thru hole allows the environmental sensor access to the outside elements. The wireless module can further comprise a filter element, and a locking ring wherein the filter element can be affixed to the cover. The cover can be attached to the housing encapsulating the controller, battery, and bushing.

Abstract: Design of a photon detection and counting device based on a unidimensional waveguide (1) coupled to a number of bistable absorbent elements (2) that carry out the detection, said device being applied to the detection and characterisation of microwave radiation (3). Said detection is carried out using qubits, the states of which are irreversibly changed during the passage of the absorbed photons stemming from the induced radiation.
