Latest Patents

Jan Petr's latest patents include an "Analog-to-digital measurement and calibration system for electrical" and a "Temperature compensation circuit." The analog-to-digital measurement system is designed to measure the energy output from one or more electrical energy sources. It first makes an analog power measurement and converts the resultant output into digital form. The A/D converter features a sigma-delta modulator in series with a digital filter. The output from the A/D converter is then inputted to a digital quantizer via a serial interface. A programmable calibration value is also inputted into the digital quantizer from a computer through non-volatile memory, allowing the operating level of the digital quantizer to be controlled by the computer.

The temperature compensation circuit is designed for a power measurement device and includes an input sensor with a temperature-dependent transmission factor. This sensor is connected to a signal processor, which also has a temperature-dependent transmission factor. The transmission factor of the signal processor is inversely proportional to a temperature-dependent reference voltage, which is inputted to the signal processor to make the combined transmission factor temperature independent. The desired temperature coefficient value of the reference voltage can be programmed into the temperature compensation circuit to accommodate variations in temperature coefficient characteristics of the internal components.
