  • Potentiometer multiplier circuit, and an electrical energy meter including such a circuit
    Patent number: 5446374
    Abstract: A circuit has two multiplier modules. Each multiplier module has at least one controllable potentiometer for adjusting the amplitude ratio between an output signal and an input signal of the module. The potentiometers have substantially identical characteristics and they are controlled in the same manner such that the amplitude ratios of the multiplier modules are substantially equal. One of the modules receives as its input signal the first signal to be multiplied and delivers an output signal that is proportional to the product of the two operands, while the other module receives as its input signal a reference voltage and as its output signal it delivers a feedback signal which is servo-controlled to a value that is approximately equal to the value of the second signal to be multiplied. The circuit is applicable to meters for electrical energy.

  • Circuit for controlling the lines of a display screen and including test means with a single output
    Patent number: 5262720
    Abstract: A circuit for controlling the lines of a display screen and including a t means with a single output is disclosed. The test means includes a single test control line (LCT), a single test output line (LST) and a plurality of sample holders (CEBj) and associated gates (Pj) and switches (Ij). The output voltage of the sample holders is transmitted onto a test output block (ST).
