  • Method and apparatus for testing the quality of fruit
    Patent number: 5811680
    Abstract: A method of testing the quality of a fruit including applying a dynamic impact force to the fruit, detecting the mechanical response of the fruit to the dynamic force via a piezoelectric film transducer supported on a displaceable resilient base member such that the film transducer is bent by the dynamic impact force, to induce a strain in the film transducer, and the film transducer outputs an electrical signal corresponding to the change of the induced strain in the film transducer caused by the dynamic force and analyzing the electrical signal to indicate the quality of the fruit. Apparatus for carrying out the method is also described and claimed.
