Abstract: Apparatus is provided for measuring and displaying impact received by fruit and vegetables during processing. An impact measuring module, having the approximate configuration of an individual fruit or vegetable article, incorporates impact measuring means and data transmitting means. The module is adapted for emplacement within a batch of fruit or vegetables, and as it experiences impact or movement, electrical impulses are transmitted to a remote receiving unit. The receiving unit incorporates data display means to visually display the impact data stream. The receiving unit may also incorporate data recording means and event marker means to permit a user to correlate visually observed events within the processing operation with the data stream recorded by the receiving unit. The data stream may be recorded within the receiving unit, for downloading into a computer.
