Specific Application Of Weight Responsive Control System Patents (Class 700/305)
  • Publication number: 20020040260
    Abstract: In a method for the control of a fast dynamic scale a first operating mode controls the transport device for transport of postal matter to a further processing station, a measurement with a weighing cell during the transport is made and an evaluation of the measured values with the letter format microprocessor for the weight determination given dynamic weighing, and weighed values are supplied to the further processing station. An automatic switching into a second operating mode for the semi-dynamic operation of the scale with static weighing ensues dependent on the result of a determination of the dimensions of the following piece of mail in a first processing station arranged upstream in the mail stream.

  • Patent number: 6246967
    Abstract: The present invention is a Weight Verification Device (WVD) that stamps a weight transaction record with a digital signature so that transaction data may be verified at a later time. The WVD is an Application Specific Integrated Circuit (ASIC) device that is installed in a sealed digital weight indicator. When a vehicle is weighed using this digital weight indicator, a weight transaction record is stamped with a digital signature and stored in a computer. The WVD may be used to confirm that the inbound and outbound weights and the date and time are accurate, that the transaction data have not been tampered with, and that the transaction as a whole has not been modified in any way since the time the transaction record was created. The digital signature stored with the transaction data is based on a secure hash of the transaction data and a “private” key belonging to an inspector from the Weights and Measures Department or a designated representative.
