The device includes at least one information communication unit configured to communicate the information, and at least one power providing arrangement including at least one power source, at least one electrical switch and at least one switch lock member. The at least one switch lock member being configured to be movable in an axial direction from a first position to a second position by an axial movement of at least one triggering member of the medicament delivery device, to cause a change of state of the at least one electrical switch in the second position, thereby providing electrical power to the at least one information communication unit from the at least one power source, and to be locked in the second position, such that the change of state of the electrical switch is maintained.

A drug delivery device, comprising housing comprising one or more bridging contacts; a movable dial located at least partially within the housing and arranged to move relative to the one or more bridging contacts, the movable dial comprising a series of conductive strips on an exterior surface of the movable dial, wherein the one or more bridging contacts selectively connect and disconnect conductive strips of the series of conductive strips as the movable dial moves to provide alternating electrical signals; at least one electronic component configured to: detect the alternating electrical signals; determine whether the alternating electrical signals are indicative of contact between conductive strips of the series of conductive strips and the one or more bridging contacts; and based on the alternating electrical signals, determine a medicament dosage programmed into the drug delivery device.

Methods and apparatus provide controlled operations in an oxygen concentrator (100) such as by adjusting valve opening time to regulate amount of oxygen enriched air released to a user. The apparatus may generate, with a sensor configured to sense pressure at a location associated with accumulation of enriched air produced by the concentrator, a signal representing measured pressure of the accumulated enriched air. The apparatus may generate, with a sensor, a signal indicative of respiration of a user of the concentrator. The apparatus may include a controller configured to receive the measured pressure and respiration signals. The controller may control, responsive to the respiration indication and according to a target duration, actuation of a valve adapted to release a bolus of accumulated oxygen enriched air. The controller may dynamically determine the target duration during the release of the bolus according to a function of a value of the measured pressure.

An injector has a cartridge door movable between a fully closed position and a fully open position. A power supply is employed to power at least one power-operated component of the injector. A power supply circuit electrically connects the power supply with the at least one power-operated component. An electrically insulated arm is movable from a first state, in which the electrically insulated arm electrically disconnects the power supply from the circuit, to a second state, in which the electrically insulated arm connects the power supply with the circuit to provide power to the at least one power-operated component. The insulated arm is coupled to the cartridge door and initially positioned in the first state thereof in the fully closed position of the cartridge door, whereby movement of the cartridge door out of the fully closed position toward the fully open position moves the arm to the second state thereof.

Devices, systems and methods are provided to implement key generation for secure pairing between first and second devices using embedded out-of-band (OOB) key generation and without requiring the devices to have input/output (IO) capability to enter authentication information. Bluetooth Smart or Low Energy (BLE) OOB pairing option can be used for pairing medical devices with added security of OOB key generation. The OOB key generation comprises providing first and second devices with the same predefined credential and secure hashing algorithm, and making input of the hashing algorithm of the first and second devices the same. The first device transmits unique data to second device (e.g., via BLE advertising) to share and compute a similar input. The first and second devices use the credential and shared data with the hashing function to generate a key that is the same at each of first and second devices.

An injection device including a stopper and an electromechanical switch. The stopper includes an electronics assembly. The electromechanical switch is operable to be activated to power the electronics assembly. The stopper is configured to transition between a first size and a second size to activate the electromechanical switch.

An aerosol generation device includes an internal clock, a communication interface, and a controller. The controller is configured to record one or more events and apply one or more internal timestamps respectively to the one or more events, the one or more initial timestamps relative to an initial internal time point; receive, by the communication interface, a present external time point; update the internal clock from a present internal time point, relative to the initial internal time point, to the present external time point; and adjust the one or more internal timestamps respectively to one or more external timestamps based upon the difference between the present internal time point and the present external time point.
