Abstract: A control system for controlling a powertrain of an electric or hybrid electric vehicle is disclosed. The powertrain comprises a battery and a traction motor and is operable in a regenerative braking mode. The control system is configured to generate a deceleration target for the vehicle in the regenerative braking mode, and to generate a torque command for the traction motor based on the deceleration target. By generating a deceleration target for the vehicle during regenerative braking and using the deceleration target to control the torque of the traction motor, more consistent regenerative braking may be provided, particularly when the vehicle is used to carry different loads.

Abstract: Robots might interact with planar objects (e.g., garments) for process automation, quality control, to perform sewing operations, or the like. It is recognized herein that robots interacting with such planar objects can pose particular problems, for instance problems related to detecting the planar object and estimating the pose of the detected planar object. A system can be configured to detect or segment planar objects, such as garments. The system can include a three-dimensional (3D) sensor positioned to detect a planar object along a transverse direction. The system can further include a first surface that supports the planar object. The first surface can be positioned such that the planar object is disposed between the first surface and the 3D sensor along the transverse direction. In various examples, the 3D sensor is configured to detect the planar object without detecting the first surface.

Abstract: The handling of external calls from one or more services to one or more subservices is described. Upon detecting that a service has made an external call to a subservice and prior to allowing the external call to be sent to the subservice, a system evaluates the external call against one or more pre-call thresholds to determine whether or not the one or more pre-call thresholds are met. If the determination is that a pre-call threshold of the one or more pre-call thresholds is not met, the external call is failed without sending the external call to the subservice. This failing might include communicating to the service that placed the external call that the external call has failed. Otherwise, the system sends the external call to the subservice. By applying these thresholds, the service is kept from using too many resources.

Abstract: A universal asynchronous receiver/transmitter includes a transmission register to include information to be transmitted, a receive register to include information received, a frame error checking circuit to evaluate contents of the receive register for a frame error, and control logic. The control logic is to route the contents of the transmission register to the receive register. The control logic is to, during transmission of the contents of the transmission register through the reprogrammable pin to the receive register, modify a bit inversion register to yield modified contents to be provided to the receive register. The modified contents are to cause a frame error. The control logic is to determine whether the frame error checking circuit detected the frame error.

Abstract: An architecture for training the weights of artificial neural networks provides a global constrainer modifying the neuron weights in each iteration not only by the back-propagated error but also by a global constraint constraining these weights based on the value of all weights at that iteration. The ability to accommodate a global constraint is made practical by using a constrained gradient descent which approximates the error gradient deduced in the training as a plane, offsetting the increased complexity of the global constraint.

Abstract: Optimizing performance of an autonomous vehicle (AV) includes acquiring information pertaining to a plurality of factors associated with the AV. The plurality of factors includes a route to be traversed by the AV for a ride, a type of a road included in the route, a real-time location of the AV, a time of travel, and a weather condition at the time of travel. An optimal configuration is selected based on the acquired information for operating components of the AV. The components are configured in real time to operate at the optimal configuration. When the components operate at the optimal configuration, a power consumed by the components is reduced and a durability of the components is increased relative to when the components operate at a first configuration that is different from the optimal configuration.

Abstract: Embodiments include simultaneous localization and mapping in an autonomous machine using unsynchronized data from a plurality of sensors by receiving navigation information from a first sensor and a second sensor of a plurality of sensors. The navigation information from the first sensor is not time synchronized with the localization information from the second sensor. A constraint equation can be applied to the navigation information from the first sensor, the constraint equation comprising a point-to-line constraint, wherein a line of the point-to-line constraint is based on a trajectory of the autonomous machine determined from the navigation information. Localization of the autonomous machine and mapping of physical surroundings of the autonomous machine can be performed using the point-to-line constrained navigation information and the localization information from the second sensor.

Abstract: Methods and systems herein can let an autonomous vehicle localize itself precisely and in near real-time in a digital map using visual place recognition. Commercial GPS solutions used in the production of autonomous vehicles generally have very low accuracy. For autonomous driving, the vehicle may need to be able to localize in the map very precisely, for example, within a few centimeters. The method and systems herein incorporate visual place recognition into the digital map and localization process. The roadways or routes within the map can be characterized as a set of nodes, which can be augmented with feature vectors that represent the visual scenes captured using camera sensors. These feature vectors can be constantly updated on the map server and then provided to the vehicles driving the roadways. This process can help create and maintain a diverse set of features for visual place recognition.
