Latest Patents

One of Xi Fang's latest patents is a "Bidirectional transmission circuit for universal signal." This invention comprises an intrinsically safe energy limiting module, a first signal coupling module, an isolation transformer module, a second signal coupling module, and a control module. The first signal coupling module adjusts a first direct current signal of a universal signal to a first alternating current signal. The isolation transformer module transmits the first alternating current signal to the second signal coupling module in an isolated manner. The second signal coupling module then adjusts the first alternating current signal to a second direct current signal for a universal signal receiving terminal. Additionally, the second signal coupling module further adjusts a third direct current signal of a control signal to a second alternating current signal, while the first signal coupling module adjusts the second alternating current signal to a fourth direct current signal for a control signal receiving terminal.

Another significant patent is the "Digital-to-analog conversion device and method." This invention provides a control module that splits the input digital signal into n intermediate digital portions. It divides these portions by corresponding conversion coefficients to obtain n intermediate digital signals, which are then transmitted to n conversion modules. The conversion module performs digital-to-analog conversion on an intermediate digital signal to produce a result that includes the conversion coefficient of the conversion module. An adder is used to combine the output signals of the n conversion modules to generate an analog signal. The feedback module obtains a feedback signal based on the analog signal, allowing the control module to adjust the allocation of the n intermediate digital portions according to a target digital signal and the feedback signal.
