Abstract: In various example embodiments, a system and method for dynamically generating virtual marketplace platforms are presented. The system receives a set of facility data, a set of selections for a set of user interaction objects, and a set of object placement selections. The set of user interaction objects includes a first subset and a second subset. The system generates a virtual facility comprising the facility data and the set of user interaction objects distributed based on the object placement selections. The system receives user data for a user interacting with the virtual facility and one or more objects of the first and second subset of user interaction objects, dynamically arranges the second subset of user interaction objects into a second arrangement and causes presentation of the virtual facility and the set of user interaction objects to the user.

Abstract: This application relates to improvements in environments for microbial testing. Exemplary embodiments provide a uniquely configured tray containing an environment conditioning material, such as an oxygen scavenger material, for use with a cassette assembly. Furthermore, some embodiments provide a cutting mechanism that allows the tray to be reliably breached, thereby exposing the material inside to the environment. Some embodiments can cut open the material with specially-configured cutter teeth, which can easily be deployed by twisting or pushing two halves of the cassette assembly.

Abstract: Path extraction for a vehicle on a guideway, the vehicle having two or more sensors. Two or more sensor inputs are received from two or more sensors including at least one active 3D sensor input from at least one active 3D sensor and at least one passive 2D sensor input from at least one passive 2D sensor. At least one active 3D sensor path is extracted based on the at least one active 3D sensor input and at least one passive 2D sensor path based on the at least one passive 2D sensor input. At least one 3D sensor ground surface model is generated based on the at least one passive 2D sensor path. At least one passive 3D path is generated based on the at least one passive 2D sensor path and the at least one 3D sensor ground surface model. The at least one passive 3D path and the at least one active 3D sensor path are fused to produce a consolidated 3D path. In a path extraction pipeline, at least one supervision check is performed for providing integrity to the consolidated 3D path.

Abstract: A fluid recycling unit for use on board an aircraft or other passenger transportation vehicle. The fluid recycling unit captures various types of used fluids, filters or otherwise appropriately treats the fluids, and recycles the fluids for various uses onboard the vehicle.

Abstract: A system for determining a stationary state of a rail vehicle on a track includes a first radar mounted at an end of the rail vehicle and a second radar mounted at another end of the rail vehicle. A speed sensor is mounted on the rail vehicle. A series of fixed reflective track features are found along the track. A processing unit, communicably connected with the speed sensor, the first radar and the second radar receives data from the first radar and the second radar corresponding to the distance to the fixed reflective track features and determines the stationary state or low-speed condition of the rail vehicle and checks the state or condition by comparing it with an output of the speed sensor.

Abstract: A vehicle locator includes an on-board computer and a ground penetrating radar mounted on the vehicle that is communicably connected to the on-board computer. A reflective landmark is located at a known location along the path of the vehicle. The reflective landmark includes reflective elements arranged to encode data. The ground penetrating radar transmits signal energy and detects reflected signal energy reflected by the reflective landmark and communicates encoded data representative of the reflected signal energy to the on-board computer. The on-board computer decodes the encoded data and thereby determines the location of the vehicle.

Abstract: A method of improving robustness of a deep neural network (DNN), the method including: applying a coverage metric to a trained DNN based on a test set to determine test set adequacy; monitoring a performance of the trained DNN; based on the performance, applying new data to the trained DNN; applying a novelty metric to an output of the trained DNN based on the applied new data to identify a subset of the applied new data in response to determining whether new features are generated; and identifying the subset of the applied new data.

Abstract: A system described herein uses data obtained from a wearable device of a first user to identify a second user and/or to determine that the first user is within a threshold distance of the second user. The system can then access an account of the second user to identify one or more items and retrieve model data for the item(s). The system causes the wearable device of the first user to render, for display in an immersive 3D environment (e.g., an augmented reality environment), an item associated with the account of the second user. The item can be rendered for display at a location on a display that is proximate to the second user (e.g., within a threshold distance of the second user) such that the item graphically corresponds to the second user. The item rendered for display may be an item of interest to the first user.

Abstract: In various example embodiments, a system and method for facilitating display of virtual content are presented. A session that displays two-dimensional (2D) content of one or more items available for sale is presented on a first device of a user. A second device of the user is detected, the second device being able to display three-dimensional (3D) content of the one or more items available for sale. 3D content of the one or more items available for sale is retrieved. Display of the 3D content on the second device is caused, the 3D content selectable by the user to perform interactions with the 3D content. An indication of the user performed interactions is received and processed. A result that depicts the user performed interactions as being processed is displayed on the first device of the user.

Abstract: A rinse ring system for use on a toilet. The rinse ring is a dual channel rinse ring, which allows the toilet to be flushed with either potable water from a fresh water system or with grey water from a grey water source. Other flush fluids are possible for use. The dual channel rinse ring provides separation between entry points for potable water rinse and the grey water rinse, preventing the possibility of contamination of the potable water source with grey water.

Abstract: A method of detecting a way-side object includes receiving data frames from sensors mounted on a vehicle. Position data corresponding to the position of the vehicle is received. Object-of-interest data is retrieved from a database. The sensor data frames and the object-of-interest data are processed to determine a region-of-interest in the sensor data frame. A portion of the sensor data frames corresponding to the region of interest is processed using machine-learned object detection to identify a first object-of-interest. The portion of the sensor data frames corresponding to the region of interest is processed using computer vision methods to detect features of the expected object-of-interest and identifying the detected object-of-interest as explained when the features of the expected object-of-interest are detected. Explained object-of-interest data corresponding to the explained detected object-of-interest is output to a navigation system of the vehicle.
