1. A syringe structural characterization system comprising:
- a transducer to output a first signal proximate to a syringe pre-filled with a fluid and incorporated in a housing substantially surrounding the syringe;
a receiver to receive a response of the syringe to the first signal; and
a processing device configured to control the transducer and the receiver to determine a structural characteristic of the syringe based on the response received by the receiver;
wherein at least one of the transducer and the receiver are configured to physically contact the syringe.

Abstract
System and methods for characterizing and/or detecting structural characteristics of syringes (e.g., bare syringes or syringes included in automatic injection devices) using acoustic vibrations. A transducer is positioned proximate to a syringe so that the transducer vibrates at one or more frequencies and a response of the syringe to the vibrations can be received via the receiver. The response of syringe can be processed to determine a structural characteristic of the syringe.

15. 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. - View Dependent Claims (16, 17, 18)
