Mass or Weight Determination of Arbitrarily-Shaped Dielectric Objects by Microwave Resonator Measurements
Patent Number: 5554935
Docket Number: 1995
Serial Number: 8416405
Date Patented: 09/10/1996
Agency:
Agricultural Research Service
Issued:

Abstract:
A method for non-destructive determining the mass of arbitrarily shaped dielectric object is disclosed. The object is inserted into a microwave resonant cavity coupled to a microwave radiation source and a measuring circuit. Measurements of shift of resonant frequency and change in the transmission coefficient due to the presence of the object in the cavity are made. The mass is determined from using this information. The process is particularly useful for determining the mass of articles that are too hot or too cold or too fragile to handle and for articles that are irregular or variable in shape.
