Latest Patents

Douglas H Smith holds a patent for a printer-plotter system. This system integrates a central processor (CPU) with a printer-plotter, allowing it to print characters and plot data using a single 1 by 7 array of thermal resistors. The design ensures that both printing and plotting operations occur in real time, providing continuous and uniform traces despite variations in the plotting rate. The CPU temporarily stores data from the chromatograph and forwards it to the printer-plotter upon programmed command. As peaks in the data are detected, the system suspends plotting temporarily without losing any data, allowing characters to be printed adjacent to the peaks for effective annotation.
