Abstract:
A system (10) and method for weighing of items such as mailpieces (MP) in the presence of external vibration such as ground noise. The system (10) includes a scale system (12) having a platform (22) connected to a load cell (20), which provides an output signal to an analog-to-digital converter (24). The resulting digital output signal is processed by a low pass filter (28) and analyzed by a microprocessor (30) to determine weights of items (MP) on the platform (22). The microprocessor (30) also determines postage amounts as functions of the weights and outputs these postage amounts to a postage meter (16). The system also includes an accelerometer (32) and a limit detector (34) for generating a no go signal if external vibrations exceed a predetermined limit. The microprocessor (30) accepts a weight as valid if the external vibrations do not exceed the limit at any time while the weight is being determined and otherwise initiates an alternative weight determining method.
Abstract:
An electronic balance having highly improved accuracy of the measurement obtained by reducing the errors due to the scatter of data, which is an inevitable problem of the prior art in which the measurements have been made by calculating the simple average value of the sampled data during a predetermined period of time to avoid the interfering influences due to vibrations of the object being measured as such or caused by installing locations or windiness. In the electronic balance of this invention, the values of data sampled during a predetermined period of time are stored and at the same time the latest sampled value is compared in order with the previously stored values. When the value of difference obtained by the comparison is within a predetermined acceptable allowance, calculations are made for all the stored values to derive an average value. If the difference is beyond the allowance, the stored data are erased and the operations of sampling and comparison are repeated until the scatter of all the sampled values may come within the limit allowed. Since the electronic balance of this invention is capable of measurement with high accuracy even under the vibrative circumstances, it may be effectively used for body-weight measurement of laboratory animals or various kinds of control system in factories, and further is applicable to measurement systems which are equipped on moving carrier means such as cars, ships and the like.
