Abstract: A drive system for a high torque mechanical load includes a power supply, a controller, and a high torque electric motor. The electric motor includes a rotor that is oriented eccentrically relative to a stator. In one form, the electric motor has a crankshaft that transmit the torque to the mechanical load. In other variations, the electric motor includes at least two electric motor lobes with opposite stroke positions to provide a smoother output at higher speeds. During operation, the rotor is magnetically attracted to the energized electromagnet. With the rotor attracted to the electromagnet in the stator, the rotor contacts or comes in close proximity to the stator at a contact area. The close proximity between the rotor and stator at the contact area allows very large magnetic forces to be utilized to produce torque without increasing the size or weight of the electric motor.

Abstract: A biocompatible textile and methods for its use and fabrication are disclosed. The textile may be fabricated from electrospun fibers forming windings on a mandrel, in which the windings form openings having a mesh size between adjacent windings.

Abstract: The present invention relates to the reduction of multi-sensor data when used as input to machine-learning (ML) models. Typically, ML models use sensor data to learn characteristics of a problem domain. This data is usually input to the ML model in an end-to-end fashion: the data from sensor 1 is appended with the data from sensor 2, etc., until the entire concatenated data set forms a single input example from which the model learns. The more sensors, the more data, the larger the size of the data input to the ML model, and the longer it is likely to take to train and run the model. Disclosed is a method to combine data from multiple sensors, reducing it into a smaller input data space. The data from 2 or more sensors of the same type can be combined in the same input data space, to simplify the input data size, enabling smaller, faster machine-learning models.
