Abstract: A recharging and medication storage hub for a re-usable drug-delivery device is provided. According to some embodiments, the hub comprises a housing defining a port sized to receive at least part of the re-usable drug-delivery device, a charging station disposed on the housing configured to charge a rechargeable power source mounted on the drug-delivery device, and a medication storage chamber disposed in alignment with the port, the storage chamber configured to store a single-use medication cartridge. When at least part of the drug-delivery device is inserted through the port and into the medication storage chamber, a coupling mechanism is configured to releasably couple with and withdraw the medication cartridge from the medication storage chamber. In some embodiments, the hub may further comprise a temperature-changing device configured to control an interior temperature of the medication storage chamber.

Abstract: Medication delivery devices are provided having a housing comprising a reservoir sized sufficiently to hold medication, a dose button being rotatable relative to the housing to select a dose size of the medication for an injection, a printed circuit board, a switch mounted to the printed circuit board, and a controller in communication with the switch. The controller is configured to generate a first count of a set of signals using a first counting technique, generate a second count of the set of signals using a second counting technique, and determine, based on the first and second count, reliability data of the first and/or second count. The controller can connect, using a wireless communication module, to a remote computing device to wirelessly communicate with the remote computing device over an unencrypted wireless communication channel, and transmit, using the wireless communication module, encrypted data to the remote computing device.
