Abstract: An initial environment navigation model for a physical environment may be determined based on sensor data collected from a mobile enrollment device. The sensor data may include data collected from a first one or more cameras at the mobile enrollment device. The initial environment navigation model may be sent to a robot via a communication interface. The robot may be instructed to autonomously navigate the physical environment based on the initial environment navigation model and additional sensor data collected by the robot. An updated environment navigation model for the physical environment may be determined based on the initial environment navigation model and the additional sensor data.

Abstract: One or more simulated capture paths through a physical environment may be determined for a robot based on an environment navigation model of the physical environment. A plurality of simulated object parameter values may be determined for an object type. Simulated sensor data for a plurality of simulated instances of the object type may be determined based on the one or more simulated capture paths, the environment navigation model, and the simulated object parameter values. An object recognition model to recognize an object corresponding with the object type based on the simulated sensor data.

Abstract: A cleaning robot may determine a three-dimensional model of a physical environment based on data collected from one or more sensors. The cleaning robot may then identify a surface within the physical environment to clean. Having identified that surface, the robot may autonomously navigate to a location proximate to the surface, position an ultraviolet light source in proximity to the surface, and activate the ultraviolet light source for a period of time.

Abstract: An agricultural sprayer includes a purge tank and first and second nozzles. Furthermore, the system includes a first valve fluidly configured to selectively permit air to flow to the first nozzle and a second valve fluidly configured to selectively permit the air to flow to the second nozzle. A computing system is configured to receive an input indicative of initiation of a purging operation and, upon receipt of the input, control an operation of a main valve to allow the air to flow through a main fluid conduit. Furthermore, the computing system is configured to monitor the air pressure associated with the purge tank and control the operation of the first and second valves during the purging operation based on the monitored air pressure.

Abstract: A system and method are provided for controlling a plurality of fuel cells. The method includes coordinating a distribution of a power demand in response to a power request of a power system comprising a plurality of fuel cells, the power output of each of the fuel cells selected based on a respective efficiency of each of the fuel cells.

Abstract: This application describes systems, devices, computer readable media, and methods for the function and operation of robotic carts. A robotic cart may include a base component configured for the receipt of a payload, a battery unit, and a mobility apparatus. The robotic cart may include a handlebar component coupled with the base component. The handlebar unit may include a sensor unit configured to transmit a hand detection message when the handlebar unit is grasped by one or more hands and to transmit a force direction message indicating a two-dimensional direction associated with a directional force applied by one or more hands. The robotic cart may be configured to map the area around it and to autonomously move the robotic cart along a path to perform a task.

Abstract: An airplane jack to lift a light airplane nose wheel off the ground by the nose wheel fork to allow maintenance. The jack uses a lever to manually pivot on rollers to lift the nose wheel fork by non-marring cradling supports. A sliding lever provides unencumbered wheel access and extra safety against any possible pivoting of the jack by repositioning the lever. The jack's width can be adjusted to work with a plurality of nose wheel forks and varied in size and material to operate with a plurality of airplanes.

Abstract: A robot may identify a human located proximate to the robot in a physical environment based on sensor data captured from one or more sensors on the robot. A trajectory of the human through space may be predicted. When the predicted trajectory of the human intersects with a current path of the robot, an updated path to a destination location in the environment may be determined so as to avoid a collision between the robot and the human along the predicted trajectory. The robot may then move along the determined path.

Abstract: Certain aspects involve managing permissions in collaborative workspaces using visual representations of clients. For example, a graphical interface can be displayed that represents a collaborative workspace and that includes visual representations of different clients accessing the workspace. A workspace application executed by a processor can determine that visual representations for at least two clients are positioned in a common region of the graphical interface. The workspace application can authorize the clients to collaboratively modify electronic content that is accessible via the graphical interface based on the visual representations being positioned in the common region. Subsequently, the workspace application can determine that the visual representations are positioned outside the common region and restrict access to the collaboratively modified content accordingly.

Abstract: A roof assembly for a storage container, such as a truck trailer, includes a sheet having a plurality of laterally-extending corrugations formed therein. Illustratively, each corrugation is configured to progressively flatten outwardly from a longitudinal centerline of the roof assembly towards an outer end of the sheet. The longitudinal centerline of the roof assembly extends perpendicular to each corrugation. The outer end of the sheet is configured to be coupled to a sidewall of the truck trailer.

Abstract: The invention provides for an apparatus and process for vaporizing liquefied natural gas using groundwater. The invention provides for an apparatus including: a groundwater well; a vaporizer for vaporizing LNG; and an LNG tank. The invention also provides for a process including vaporizing LNG in a vaporizer using groundwater.

Abstract: A system and method to facilitate development, installation, support and maintenance of international versions of application programs and support tools. Language-specific user interface (UI) messages are placed into a message file which is compiled to produce a message source code file and a message definitions and symbols file. The application source code is modified or originally developed to utilize the functions provided by the message source code file, and a language-specific unified application executable program is created by compiling and linking. This language-specific executable program can then be installed on an end users computer without necessity of installing related resource or message catalog files, and without necessity of properly setting environment variables. Application programs for users in alternate languages are produced by translating the message file, and repeating the compiling and linking steps, without need to modify the application source code.
