Abstract: A method, computer program, and computer system is provided for an all-deep-learning based AEC system by recurrent neural networks. The model consists of two stages, echo estimation stage and echo suppression stage, respectively. Two different schemes for echo estimation are presented herein: linear echo estimation by multi-tap filtering on far-end reference signal and non-linear echo estimation by single-tap masking on microphone signal. A microphone signal waveform and a far-end reference signal waveform are received. An echo signal waveform is estimated based on the microphone signal waveform and a far-end reference signal waveform. A near-end speech signal waveform is output based on subtracting the estimated echo signal waveform from the microphone signal waveform, and echoes are suppressed within the near-end speech signal waveform.

Abstract: An electromechanical joint provides rotational movement in at least two dimensions while conducting electrical power between orthogonal hubs. The joint, shaped as a cross, has four conical shafts positioned orthogonally and apart from each other within an interior of a housing. Apexes of the conical shafts face each other proximate a centroid of the housing. A conductive fluid, such as Galinstan, fills recesses between the conical shafts. Separate yokes attached to pairs of the hubs may impart forces on the shafts, causing the shafts to rotate within the conductive fluid around orthogonal axes. The conductive fluid provides simultaneous conduction of electrical power between the hubs. The yokes may be affixed respectively to a current collector and conductive arms of a work machine for improved movement and power conduction without the need for additional components.
