Title: Innovations of Yueh-Mei Hou
Introduction
Yueh-Mei Hou is a notable inventor based in Taoyuan Hsien, Taiwan. She has made significant contributions to the field of electronics, holding a total of 3 patents. Her work primarily focuses on programmable devices and interface circuits, showcasing her expertise in innovative technology.
Latest Patents
One of her latest patents is a "Programmable precise frequency divider." This invention involves a programmable precise frequency divider that works in conjunction with a low-frequency crystal and an oscillating circuit. The divider comprises a low-frequency oscillating circuit, a preset code memory, a programmable preset code loader, an adder, and a register. The programmable preset code loader is designed to load and latch a preset code from either the preset code memory or an external data source. The adder sums the latched preset code and the current value from the register, supplying a resultant value to the register. This register accumulates the resultant value and the oscillating signal, ultimately providing an output clock signal with the desired divided frequency.
Another significant patent is a "Method and interface circuit for scanning keys and external resistors." This invention includes an I/O device with multiple output and input ports, allowing for the construction of key dispositions and external resistor dispositions. The interface circuit features a clock generator that facilitates the scanning of keys and external resistors in response to the clock. Additionally, it includes an external resistor detector and a key input detector, which latch scanning results and output detecting signals to identify keys and change system functions.
