Latest Patents

One of Hung-Ta Shih's latest patents is a load identification system. This system includes an AC-power input unit, a load, a zero-crossing detector, a microcontroller, and both first and second current phase detectors. The zero-crossing detector is designed to output a zero-voltage pulse signal when it detects a zero-crossing signal from the AC-power input unit. The first current phase detector monitors the current flowing through the load and outputs a first voltage signal, which is at a high level when the current flows in a first direction. Similarly, the second current phase detector outputs a second voltage signal at a high level when the current flows in a second direction. The microcontroller processes these signals to identify the type of load.

Another significant patent is the light-emitting diode driving system and its associated burning method. This system comprises an infrared ray burning device and a light-emitting diode driving device. The driving device includes an infrared ray receiving unit, a signal transforming unit, a storage unit, a pulse width modulating unit, and a diode driving unit. The infrared ray receiving unit captures a burning signal from the infrared ray burning device. The signal transforming unit converts this signal into a current control command, which is then stored and used to generate a pulse width modulation output current control signal. This signal ultimately drives the light-emitting diode.
