  • Publication number: 20260180665
    Abstract: Methods and systems for controlling an antenna array of an automated medicament delivery device are disclosed. The method includes causing the antenna array to transition between multiple array configurations. The multiple array configurations are chosen from among configurations that vary at least one characteristic of a signal emitted or received by one or more antennas of the antenna array, configurations that vary an activation status of the plurality of antennas, and configurations that vary a combination of the at least one characteristic of a signal and an activation status of the plurality of antennas. The method also includes measuring a power of a received signal for each configuration of the multiple array configurations of the antenna array. The method further includes selecting an array configuration of the multiple array configurations based at least in part on results of the measuring and setting the antenna array to the array configuration selected.

  • Patent number: 12656151
    Abstract: In an aspect, a system for determining a liquid level in a drug delivery device is presented. The system includes a first spring and a second spring positioned adjacent the first spring. The system includes a rod configured to compress at least the first spring and contact the second spring. The system includes a sensing element in communication with the first spring and the second spring. The sensing element is configured to detect a difference in voltage of at least the first spring. A difference in voltage of at least the first spring corresponds to an amount of liquid drug of the drug delivery device.

  • Publication number: 20260106370
    Abstract: An automated medicament delivery device for automated administration of medicament to a user-body is disclosed. The automated medicament delivery device includes a delivery system, a housing, a printed circuit board (PCB), one or more antennas, an adhesive liner, and a reflective ground shield. The delivery system is configured to deliver medicament to the user-body. The housing is configured to enclose multiple components therein. The PCB is within the housing. The one or more antennas are connected to the PCB. The adhesive liner comprises a flexible substrate and an adhesive configured to secure the housing to a user-body. The reflective ground shield is between the PCB and the adhesive, the reflective ground shield being physically separated from the one or more antennas.
