Latest Patents
Muellner's latest patents include a variable gain amplifier and a pen drive for recorders. The variable gain amplifier features a digital output and is designed to optimize input range selection in chart recorders and other measuring instruments. This innovative amplifier minimizes the need for expensive precision resistors by utilizing a switching mechanism for range selection. A software routine adjusts the gain after digitization to ensure accuracy for the selected range. The entire process is managed by a general-purpose microprocessor, which can also perform additional tasks within the instrument.
The pen drive for recorders employs a direct current servo motor that operates through a toothed belt linkage to drive the pen carriage of a chart recorder. The motor's position is monitored by a sectored encoder disc, with optical sensors providing transition signals as the disc rotates. A microprocessor, triggered by these signals, determines the direction of rotation and stores a count signal. This system allows the pen to accurately follow the input signal by adjusting motor speed and preventing overshoot.
