    摘要： Embodiments described herein generally relate to devices, systems and methods for measuring a volume or number of doses remaining in a drug delivery device that is used for delivering a dose to a patient. In some embodiments, a dose measurement system for measuring the liquid volume in a container includes a light guide disposed and configured to reflect electromagnetic radiation toward the container. The dose measurement system also includes a light guide disposed and configured to emit electromagnetic radiation into the light guide. A plurality of sensors are located in the apparatus that are optically coupleable to the light guide and are disposed and configured to detect the electromagnetic radiation emitted by at least a portion of the light guide. The apparatus also includes a processing unit configured to receive data representing the portion of the detected electromagnetic radiation from each of the plurality of sensors. The processing unit is further operable to convert the received data into a signature representative of the electromagnetic radiation detected by the plurality of sensors.

    摘要： An apparatus for measuring liquid volume in a container includes a plurality of light sources for emitting electromagnetic radiation (EMR) toward the container, a plurality of sensors optically coupleable to the plurality of light sources, each sensor of the plurality of sensors for detecting the EMR emitted by at least a portion of the plurality of light sources, a temperature sensor for measuring at least one temperature associated with a liquid in the container, and at least one processor for receiving data representative of the portion of the detected EMR from each of the plurality of sensors, comparing the at least one measured temperature to a temperature guideline to identify any temperature events associated with the received data; normalizing the received data based on any temperature events associated with the received data; and converting the normalized data into a signature representative of the EMR detected by the plurality of sensors.
