Latest Patents
One of Erin's latest patents is titled "Efficient implementation of revenue and power quality functions on a processing device." This invention provides methods, devices, and systems aimed at improving the efficiency of power quality and revenue-based computations. The process includes receiving an input signal and oversampling it to generate an oversampled data stream. In a first signal path, the oversampled data stream is filtered to create a filtered data stream, which is then decimated to produce a decimated data stream. Both the filtered and decimated data streams contain waveform data that can be utilized for generating power quality analysis information. In a second signal path, the oversampled data stream is downsampled to create a downsampled data stream, which generates revenue quality power consumption data based on metadata from the downsampled data stream. Additionally, power quality data is generated based on the decimated data stream and its associated metadata.
Another notable patent is focused on "Systems and methods for removing low frequency offset components from a digital data stream." This method involves receiving an analog input signal from one or more analog front-end components at the input of an analog-to-digital converter (ADC). The analog input signal has an associated low frequency offset due to the analog front-end components. The method generates a digital data stream representative of the analog input signal, which also has a low frequency offset. By applying one or more low pass infinite impulse response (IIR) filters to the digital data stream, the low frequency offset components are detected, resulting in a filtered output signal. A corrected digital data stream is then generated by taking the difference of the filtered output signal from the digital data stream.
