Abstract:

A method for determining the state-of-charge for zinc mercuric oxide type primary cells. I-V curves of the cells are plotted and the nearly constant slopes of these I-V curves above 75mA are measured graphically. These slopes are used to define effective differential DC resistance values (. DELTA. V/. DELTA. I). sub. 75mA which have a linear relationship to charge expended, Q(A-h), which is graphically produced by plotting (. DELTA. V/. DELTA. I). sub. 75mA versus Q(A-h). This relationship is used as a basis for a state-of-charge indicator to determine the remaining charge to about 12%. One can also subtract the internal resistance of the cell (measured with an a-c bridge technique) from (. DELTA. V/. DELTA. I). sub. 75mA and obtain a new parameter, R. sub. p, which is related to the polarization resistance of the cell.

Abstract:

A microwave mixer suitable for millimeter wave radar applications. A semi-insulating gallium arsenide dielectric waveguide structure contains an embedded planar doped barrier (PDB) structure as a non-linear mixing element. The local oscillator (LO) signal is guided to the PDB structure via a coplanar type waveguide. The radio frequency (RF) signal is guided to the PDB structure via an image guide and a microstrip circuit serves to transmit the intermediate frequency (IF).
