Abstract: Methods, apparatus, and computer-readable media for determining and utilizing human corrections to robot actions. In some implementations, in response to determining a human correction of a robot action, a correction instance is generated that includes sensor data, captured by one or more sensors of the robot, that is relevant to the corrected action. The correction instance can further include determined incorrect parameter(s) utilized in performing the robot action and/or correction information that is based on the human correction. The correction instance can be utilized to generate training example(s) for training one or model(s), such as neural network model(s), corresponding to those used in determining the incorrect parameter(s). In various implementations, the training is based on correction instances from multiple robots. After a revised version of a model is generated, the revised version can thereafter be utilized by one or more of the multiple robots.

Abstract: A method of fabricating a light emitting diode (LED) includes forming an active region structured to emit ultraviolet (UV) light and disposed between a first n-type semiconductor region and a first p-type semiconductor region. The method also includes forming a tunnel junction, where the first p-type semiconductor region is disposed between the active region and the tunnel junction, and where the tunnel junction is electrically coupled to inject charge carriers into the active region through the first p-type semiconductor region. A second n-type semiconductor region is also formed, where the tunnel junction is disposed between the second n-type semiconductor region and the first p-type semiconductor region.

Abstract: Described herein are methods and systems that help facilitate the summoning and loading of a pickup and delivery unmanned aerial vehicle (UAV). In particular, a computing system may display a graphical interface including an interface feature that indicates UAV assignments. That computing system may receive a message including a UAV identifier that identifies a particular UAV assigned to a particular item based on a UAV-assignment request for the particular item. And the computing system may use the received UAV identifier as a basis for displaying, on the graphical interface, (i) a graphical identifier of the particular UAV assigned to the particular item based on the UAV-assignment request for the particular item and (ii) a graphical identifier of the particular item.

Abstract: A light emitting diode (LED) to emit ultraviolet (UV) light includes a first n-type semiconductor region and a first p-type semiconductor region. The LED also includes an active region disposed between the first n-type semiconductor region and the first p-type semiconductor region, and in response to a bias applied across the light emitting diode, the active region emits UV light. A tunnel junction is disposed in the LED so the first p-type semiconductor region is disposed between the active region and the tunnel junction. The tunnel junction is electrically coupled to inject charge carriers into the active region through the first p-type semiconductor region. A second n-type semiconductor region is also disposed in the LED so the tunnel junction is disposed between the second n-type semiconductor region and the first p-type semiconductor region.

Abstract: Generating a robot control policy that regulates both motion control and interaction with an environment and/or includes a learned potential function and/or dissipative field. Some implementations relate to resampling temporally distributed data points to generate spatially distributed data points, and generating the control policy using the spatially distributed data points. Some implementations additionally or alternatively relate to automatically determining a potential gradient for data points, and generating the control policy using the automatically determined potential gradient. Some implementations additionally or alternatively relate to determining and assigning a prior weight to each of the data points of multiple groups, and generating the control policy using the weights. Some implementations additionally or alternatively relate to defining and using non-uniform smoothness parameters at each data point, defining and using d parameters for stiffness and/or damping at each data point, and/or obviating the need to utilize virtual data points in generating the control policy.

Abstract: Extra heat in a closed cycle power generation system, such as a reversible closed Brayton cycle system, may be dissipated between discharge and charge cycles. An extra cooling heat exchanger may be added on the discharge cycle and disposed between a cold side heat exchanger and a compressor inlet. Additionally or altematively, a cold thermal storage medium passing through the cold side heat exchanger may be allowed to heat up to a higher temperature during the discharge cycle than is needed on input to the charge cycle and the excess heat then dissipated to the atmosphere.
