Abstract: Determining contexts of mobile devices. Particular embodiments described herein include machines that determine two estimated positions of a mobile device that respectively correspond to first and second locations at first and second times, acquire sets of terrain or structural information for first and second areas that respectively include the first and second estimated positions, use the acquired sets of information and the estimated positions to determine if the mobile device was within a structure at the first and second times, determine one or more values that are indicative of vertical movement by the mobile device during a period of time between the first time and the second time, compare the one or more values to one or more threshold conditions, and determine a context of the mobile device based on the comparison.

Abstract: A method is provided for introducing a submersible robot into a fluid-filled container without draining the container. An access chamber is placed in fluid communication with the side port, and the access chamber is filled with fluid before opening the side port. The side port is then opened and the submersible robot passes from the access chamber through the opened side port to access the interior of the container.

Abstract: Disclosed herein are systems and methods for distributed computing and/or networking for mixed reality systems. A method may include capturing an image via a camera of a head-wearable device. Inertial data may be captured via an inertial measurement unit of the head-wearable device. A position of the head-wearable device can be estimated based on the image and the inertial data via one or more processors of the head-wearable device. The image can be transmitted to a remote server. A neural network can be trained based on the image via the remote server. A trained neural network can be transmitted to the head-wearable device.

Abstract: Traversing, by an autonomous vehicle, a vehicle transportation network, may include identifying a policy for a scenario-specific operational control evaluation model of a distinct vehicle operational scenario, receiving a candidate vehicle control action from the policy, wherein, in response to a determination that an uncertainty value for the distinct vehicle operational scenario exceeds a defined uncertainty threshold, the candidate vehicle control action is an orientation-adjust vehicle control action, and traversing a portion of the vehicle transportation network in accordance with the candidate vehicle control action, wherein the portion of the vehicle transportation network includes the distinct vehicle operational scenario.

Abstract: A passive altimeter system comprising an angle between a point and a central boresight that is determined from distortion parameters of a lens in an infrared sensor in a countermeasure system on a mobile platform wherein the infrared sensor captures a first image for determining a distance between the platform and one of (i) a ground surface and (ii) a target, and the passive altimeter system further comprising a dimensional distance between two points in the first image that is determined from a secondary source external to the countermeasure system, and a processor to triangulate the distance between the platform and one of (i) the ground surface and (ii) the target based on the dimensional distance and the angle.

Abstract: Described in detail herein is an automated marking system. The autonomous robot device can locate and identify one or more cases stored in at least one of a plurality of bins in the first location of the facility, wherein each case containing a set of like physical objects. The autonomous robot device can transmit identifying information of the at least one of the one or more cases to the computing system. The computing system can determine a priority for a quantity of the first set of like physical objects to be moved from the at least one of the one or more cases to the second location of the facility. The computing system can instruct the at least one autonomous robot device to mark the at least one of the one or more cases with an identifying mark denoting the determined priority.

Abstract: A drone traffic management system is provided, the system comprising a mapping module, which is either installed or fitted on each drone or which is accessible by each drone before and/or during flight, the mapping module defining a flying level (or airway) in respect of which the drone is obliged to fly within during a particular flight. A controller is provided at each drop off zone to control the exit of the drone from its designated flying level to enable it to arrive at its destination. In an embodiment, the system includes a central control station to monitor the flying drones, and to detect when a drone is off course and/or not flying at its designated flying level for its particular flight. Regarding the latter, the control station is allowed to take over control of the drone, but typically only under certain conditions and in accordance with determined regulations.
