Latest Patents

Varun Kelkar holds a patent titled "System and method of extracting motor fault signature using sparsity-driven joint blind deconvolution and demodulation." This patent presents a fault detection system designed to extract fault signatures from the time-domain stator current signal of a motor under varying load operations. The system addresses the challenges of detecting faults by solving a joint blind deconvolution-demodulation problem. The stator current is modeled as influenced by both the system response vector and a load modulation vector. A proximal alternating linearized minimization-type method is employed to solve this problem, assuming that the spectrum of the sought-after signal is sparse. The recovered stator current of a steady operating condition is then used for effective motor fault detection.
