Latest Patents
Mark Alan Stuart holds a patent for an "Optical sensor system with a dynamic threshold for monitoring toner transfer in an image forming device." This invention describes a method and device for monitoring toner transfer within an image forming device. A reflectivity sensor is utilized to sense the movement of a toner transfer gear that is operatively connected to a toner transfer system. The threshold unit generates a dynamic threshold based on the output of the reflectivity sensor. In one embodiment, the threshold unit generates the dynamic threshold based on a time-delayed average of the sensor output. An instantaneous sensor output is then compared to the dynamic threshold. Based on this comparison, the device determines how much the toner transfer gear has rotated, and consequently, how much toner has been transferred from the toner cartridge. Mark holds 1 patent.
