Publication number: 20220051778Abstract: The disclosure is concerned with privacy and integrity of personalized protected health information when transmitted to a cloud computing facility and subsequently distributed to a plurality of stakeholders. An electronic unit of a drug delivery device is configured to prepare payload data comprising data items according to an allocation scheme, and to encrypt, based on an encryption key, and transmit data including the payload data. The allocation scheme and the encryption key are defined for each of a plurality of data subscribers. Accordingly, personalized protected health information payload data is suitably protected with generator-to-subscriber or pass-through data security measures, and any intermediary node or data server in the communication network lacking a matching decryption key will not have access to unencrypted payload data.Type: ApplicationFiled: October 29, 2021Publication date: February 17, 2022Inventors: Florian Kühni, Dominik Reubi, Andreas Schneider, Simon Schüpbach

Publication number: 20210085880Abstract: Monitoring an injection process executed by a variable dose injection device with feedback means for generating a number of feedback events proportionate to the dose to be determined is disclosed. A dialed or injected dose is determined by measuring a first signal of the process comprising a first signal peak related to a feedback event; detecting the first signal peak in the first signal; selecting an evaluation interval comprising the detected peak and adapted to an expected peak duration; deriving, from the first signal limited to the evaluation interval, a feature or characterizing parameter of the feedback event; identifying, from the derived feature, the feedback event as one of a dial up, dial down, or expel feedback event, and counting identified feedback events to determine the dialed or the ejected dose. The two-stage approach with serially executed peak detection and peak identification allows to optimize data storage and processing power.Type: ApplicationFiled: November 17, 2020Publication date: March 25, 2021Inventors: Jürg STECK, Andreas SCHNEIDER, Simon DÄHLER, Jürg HIRSCHEL, Krista KAPPELER, Florian KÜHNI, Simon SCHÜPBACH, Amir FERIANI, Ludovic ZULLIGER
