Abstract: A hairpin conductor includes two wire segments each having respective first and second ends and a respective middle region. The segments are disposed in a side-by-side orientation such that their first ends are proximate each other and their second ends are proximate each other. The first ends are welded to each other and the second ends are welded to each other, or the middle regions are welded to each other, thereby providing a welded wire assembly, which is bent such that the two wire segments are bent equally to form the hairpin conductor. The hairpin conductor has a primary bend in the middle regions to form an apex thereat and first and second secondary bends in the two wire segments nearer to the apex than to the first and second ends to form respective first and second shoulders thereat. A method of forming the hairpin conductor is also presented.

Abstract: A circuit comprises a receive processing window formation subsystem, a matched filter subsystem, a keystone interpolation subsystem, a phase modulation subsystem, and an image forming subsystem. The receive processing window formation subsystem forms, for each radar return from a scene, a receive processing window containing the radar return as an unbroken radar return. The matched filter subsystem creates a motion model for a reference point target disposed at a predetermined location within the scene, based on a set of motion compensation parameters for range and range rate, to compensate for at least some effects of fast time Doppler on the reference point target. The keystone interpolation subsystem rescales slow time information from the matched filter subsystem. A phase modulation subsystem applies phase modulations to a keystone-interpolated 2-D output array of information associated with the scene, to ensure proper registration in a range-Doppler map output of the scene.

Abstract: Provided are methods, systems, and computer-storage media for developing machine learning technology that is less susceptible to bias problems. A machine learning model may be developed with reduced error attributed to one or more sensitive features by utilizing a loss adjustment weight to determine an adjusted loss function used to train the model. The loss adjustment weight may be determined based on a count of a feature-label combination of a sensitive feature. The adjusted loss function is determined and configured to use the loss adjustment weight when determining loss during model training, and the output of the adjusted loss function is an adjusted loss. The machine learning model may be trained until the adjusted loss satisfies a loss threshold, indicative of an acceptable level of model inaccuracy. Accordingly, present embodiments can provide use case specific tailoring to improve machine learning systems by removing biases associated with certain data features.
