Abstract: A refrigerator includes a cabinet defining an exterior configured for resting on a surface and an interior and a plurality of feet coupled with the cabinet along a bottom surface thereof. The refrigerator also includes a plurality of load transducers disposed between and in opposing contact with the cabinet and respective ones of the feet. The refrigerator further includes electronic circuitry including a non-transitory computer-readable medium configured to receive a signal corresponding with a gross weight of the cabinet from the plurality of load transducers and to determine the quantity of articles retained within the interior of the cabinet.

Abstract: A signal aspect enforcement method for a rail vehicle includes determining, by an on-board controller on the rail vehicle, a position of the rail vehicle; determining, by the on-board controller, whether a first signal aspect for a signal matches a second signal aspect for the signal; and determining, by the on-board controller, at least one of a route of the rail vehicle or a speed limit of the rail vehicle when the first signal aspect matches the second signal aspect. The first signal aspect is determined from first data from first system on the rail vehicle, and the second signal aspect is determined from second data from a second system on the rail vehicle, which system is different from the first system used to determine the first signal aspect.

Abstract: A dishwasher includes a tub at least partially defining a treating chamber, a rotatable spray arm comprising an outlet, and a liquid supply conduit fluidly coupled to the spray arm. A pump can be fluidly coupled to the liquid supply conduit and operated to flow liquid through an aperture in the liquid supply conduit and through the outlet in the rotatable spray arm.

Abstract: A dishwasher and method of operating a dishwasher according to a cycle of operation are described herein. The dishwasher includes a tub at least partially defining a treating chamber, a rotatable spray arm comprising a nozzle outlet, and a liquid supply conduit fluidly coupled to the spray arm. A pump can be fluidly coupled to the liquid supply conduit and operated to flow liquid through an aperture in the liquid supply conduit.

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: In some embodiments, a non-transitory computer-readable storage medium includes instructions to identify, based upon Doppler-speed determination from one or more radars, radar targets within a hitbox for determining a first stationary status of a vehicle based on tracking Doppler-speed radar targets in a hitbox region. The medium also includes instructions to identify, based upon the Doppler speed determination from the one or more radars, field-of-view (FOV) radar targets for determining a second stationary status based on a substantial number and a distribution of Doppler-speed determinations for the FOV radar targets. The medium also includes instructions to confirm, based on detecting a change in either of the first or the second stationary status of the vehicle, an acceleration sensed by an inertial measurement unit onboard the vehicle.

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.
