Latest Patents
Hsin Fu Tseng holds a patent for a "Dynamic thresholding module with IR LED light source for a contact image sensor." This invention features a dynamic threshold two-level A/D converter, also known as a tracking digitizer circuit. The module's circuitry includes a comparator circuit and a tracking low-pass filter circuit. The dynamic thresholding module processes output signals from a contact image sensor (CIS) module to develop a tracking background signal. This signal is then compared to the CIS output signals in a comparator, resulting in a two-level binary output digital signal. The design is particularly suited for use in scanning devices, especially CIS systems, and can be applied in various applications requiring pre-processed digitized video signals. The module is designed to be low-cost and low-density, allowing for easy integration with existing CIS modules without significantly increasing size or manufacturing costs. Notably, it occupies roughly half the space of existing digital circuits that achieve similar results.
