Characterization and/or detection of structural characteristics associated with syringes and/or automatic injection devices based on acoustics

A system for characterizing a syringe based on structural characteristics of the syringe comprising:

• a transducer configured to vibrate at one or more frequencies;
• a receiver to detect a syringe response to vibrations of the transducer, the syringe pre-filled with a fluid and incorporated in a housing substantially surrounding the syringe;
• and
• a syringe characterization unit configured to characterize the response detected by the receiver;
• wherein at least one of the transducer and the receiver are configured to physically contact the syringe.

A non-transitory computer readable medium storing processor executable instructions, wherein execution of the instructions by a processing device causes the processing device to:

• control a transducer to vibrate at one or more frequencies;
• receive a response of a syringe pre-filled with a fluid to vibrations of the transducer, the syringe incorporated in a housing surrounding the syringe, and at least one of the transducer and the receiver are configured to physically contact the syringe;
• and
• process the response to determine a structural characteristic of the syringe based on the response received the receiver.

A method of detecting a structural characteristic of a syringe comprising:

• inducing vibrations in one or more syringes;
• measuring a response of a syringe pre-filled with a syringe to the vibrations, the syringe is incorporated in a housing substantially surrounding the syringe;
• positioning the transducer proximate to the syringe to induce vibrations in the syringe;
• and
• positioning the receiver proximate to the syringe to receive the response of the syringe to the vibrations;
• wherein at least one the transducer and the receiver are configured to physically contact the syringe.
