Abstract: The present disclosure relates to a dose detection system for use in combination with a medication delivery device. In one aspect, the system includes a module keyed to the device and including a sensor operable to detect the relative angular position of a sensed element attached to the medication delivery device. The system determines the type of medication contained by the device, and/or the type of device, based on the detected angular position of the sensed element. In another aspect, the dose detection system is used in combination with a medication delivery device including a dose setting member which rotates relative to an actuator during dose delivery. The dose detection system includes a sensor and is operable to detect the relative angular positions of a sensed element attached to the dose setting member during dose delivery and to determine the amount of dose delivered. Related methods are also disclosed.

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.

Abstract: Medication delivery devices are provided having a dose delivery sensing capability. A dose button includes a support and a cover that at least partially encloses an electronics assembly including a sensor for detecting rotation of a component during dose delivery to determine a dosage of delivered medication. The electronics assembly includes a controller for receiving a signal from the sensor. The medication delivery device may be configured to communicate dosage delivery information to an external device.

Abstract: Medication delivery devices are provided having a sensor in the form of a switch having a conductive pad and a cantilevered arm that is moveable toward and away from the conductive pad. Contact between the cantilevered arm and the conductive pad changes the state of the switch, while lack of contact between the cantilevered arm and the conductive pad changes the state of the switch. The switch may be used to sense dosage of medication delivered during dose delivery. The switch may interact with a rotating component having a plurality of teeth that slide against the cantilevered arm during dose delivery.

Abstract: A heatsink for a printed circuit board (PCB) overlies most or all of the board. It is clamped tightly to the board with its board-facing surface in close proximity to the heat-generating components on the board. A pliant, thermally-conductive dielectric layer is sandwiched between the PCB and the facing surface of the heatsink. Lands at various heights are formed on the heatsink surface facing the PCB to be in good heat-conducting proximity to the surfaces of heat-generating circuit components of various heights on the PCB.
