Latest Patents
One of Pisau's latest patents is a "Load detection method and apparatus." This invention focuses on the safe detection of an external load attached to an AC power outlet of a power supply. The design emphasizes simplicity, offering an economical and robust mechanism for detecting external loads. The mechanism operates by applying a DC voltage to one electrical phase of the AC power outlet and coupling that voltage to the other phase through an interconnecting resistor. The differing voltages measured from the respective phases depend on the size of the interconnecting resistor and the resistive value of any load attached.
Another significant patent is the "Method and apparatus for controlling current slew rate of a switching current through an external resistive load." This invention involves a switching circuit designed to control the slew rate of the switched load current, yielding substantial independence from the load voltage. The control circuit, such as a microcontroller, utilizes bidirectional input/output ports to drive the transistor base or gate through a combination of parallel resistors. This innovative approach allows for the effective control of the slew rate of the load current.
