A data collection apparatus comprises a camera configured to obtain first and second recordings of at least a portion of a medicament delivery device, said portion including a first component and a second component, the first component being configured to move relative to the second component as medicament is expelled from the medicament delivery device. The data collection apparatus also comprises a processing arrangement configured to determine, from said first and second recordings, positions in the first and second recordings of the first component relative to the second component, and determine an amount of medicament that has been expelled by the medicament delivery device by comparing the position, in the first recording, of the first component relative to the second component with a position, in the second recording, of the first component relative to the second component.

The present invention provides a sensor module (50) adapted to be arranged in a cartridge based drug delivery device between a rotatable piston rod and a cartridge piston. The sensor module (50) comprises a first sensor structure (52, 152, 252, 352) adapted to be at least substantially rotationally locked with respect to the cartridge piston and comprising a transversal sensor surface (52.2, 152.2, 252.2, 352.2), and a second sensor structure (53, 153, 253, 353) adapted to be rotationally locked with respect to the piston rod and comprising one or more flexibly supported and axially deflectable contact members (53.1, 53.2, 153.2, 253.2, 353.1, 353.2), which are positioned distally of the transversal sensor surface (52.2, 152.2, 252.2, 352.2) and are adapted to apply a proximally directed force thereto. The first sensor structure (52, 152, 252, 352) and the second sensor structure (53, 153, 253, 353) are adapted to undergo relative rotational motion, whereby the one or more contact members (53.1, 53.2, 153.2, 253.2, 353.1, 353.2) sweep the transversal sensor surface (52.2, 152.2, 252.2, 352.2). A processor (52.5, 152.5, 252.5) determines a relative angular displacement between the first sensor structure (52, 152, 252, 352) and the second sensor structure (53, 153, 253, 353) from signals generated as the one or more contact members (53.1, 53.2, 153.2, 253.2, 353.1, 353.2) sweep the transversal sensor surface (52.2, 152.2, 252.2, 352.2).

Disclosed are systems and methods of detecting an impulse of energy given off by an injection device and determining a dosage of medicine based on the impulse. In one example, a module detects the vibrations given off by dialing a click-wheel on an autoinjector and determining the selected dosage of medicine based on the dialed dosage.

A therapeutic substance delivery apparatus includes a housing, a reservoir for holding a therapeutic substance disposed at least partially within the housing, a position sensor having at least three states, a plunger which is slidable within the reservoir, and a plunger-sensor engagement interface coupled to the plunger within the reservoir and extending from within the reservoir to outside of the reservoir. The plunger and the position sensor are arranged such that the plunger-sensor engagement interface causes the position sensor to change states as the plunger slides within the reservoir. Control circuitry identifies a new state indication of the apparatus based on (a) a change in state of the position sensor, or (b) a previous or current state of the apparatus in combination with a threshold amount of time having elapsed without the position sensor changing state. Other applications are also described.

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a system includes an injection pen device in communication with a mobile communication device having a software application to determine a recommended dose based on prior dose data, analyte data, and nutrient data and to generate a report illustrative of a relationship between the medicine data, the health data, and the contextual data.

An example position determining apparatus, includes a power source, position sensors, and a controller. The position sensors are each selectively powered by the power source and configured to provide a respective sensor reading indicating a proximity of a tracked object. The controller is configured to receive respective sensor readings from the position sensors and identify a position sensor that provided an extremum sensor reading. Based on the sensor readings, the controller selectively cause powering of certain position sensors and prevents powering of other position sensors. The position sensor that provided the extremum sensor reading is one of the powered position sensors. A position output based on the sensor readings is also provided.
