Abstract: This disclosure describes techniques and systems for encoding instructions in audio data that, when output on a speaker of a first device in an environment, cause a second device to output content in the environment. In some instances, the audio data has a frequency that is inaudible to users in the environment. Thus, the first device is able to cause the second device to output the content without users in the environment hearing the instructions. In some instances, the first device also outputs content, and the content output by the second device is played at an offset relative to a position of the content output by the first device.

Abstract: In some implementations, a controller of a work machine may obtain a first operator input associated with a shuttle shift input component of the work machine. The controller may obtain a second operator input associated with changing a position of a rotatable operator seat of the work machine. The controller may cause, in response to obtaining both the first operator input and the second operator input, a direction of movement of the work machine to change from a first direction to a second direction.

Abstract: Machine learning model optimization systems and methods are disclosed. A system receives sensor data captured by one or more sensors of a vehicle during a first time period. The vehicle uses a first trained machine learning (ML) model for one or more decisions of a first decision type during the first time period.

Abstract: Computerized systems and methods are provided for managing changes being made on a geographically diverse mobile telecommunications network. An intelligent application for network change management collects change requests to be implemented in a geographically disperse mobile telecommunications network. The intelligent application determines whether the changes to be implemented are for devices that high risk from a network impacting event, such as a major event or weather. The application initiates actions to suspend the changes from being implemented to the network until the devices are no longer at high risk from a network impacting event.

Abstract: Described herein are, among other things, techniques for implementing a dual detail encoding scheme in a distributed display system. At the host computer, an application may render a frame for a scene at a first resolution. The host computer may generate a two-dimensional (2D) array of pixels for the frame, encode the 2D array of pixels, and transmit the encoded pixel data to the display device. The 2D array of pixels comprises, for each eye, a copy of the frame downscaled to a second resolution less than the first resolution, and a copy of a subregion of the scene. At the display device, the encoded pixel data is decoded to obtain the 2D array of pixels for the frame, which is modified by enlarging the copies of the frame so that images can be generated using the enlarged copies of the frame and the copies of the subregion with blending.

Abstract: Optical positional tracking systems that may be used in virtual reality (VR)/augmented reality (AR) applications are described. Exemplary implementations comprise one or more receivers and one or more transmitters. Exemplary transmitters contain two orthogonal rotors that each emit a fan-shaped laser beam. Each beam is swept as the rotors are spun at constant speed. Exemplary optical receivers can be relatively small, and mounted at convenient locations on the VR display. These receivers consist of small optical detectors that may be mounted on head-mounted VR displays. Exemplary systems determine position by measuring the time at which each swept beam crosses each receiver/detector.
