  • Publication number: 20220291690
    Abstract: The technology relates to controlling a vehicle in an autonomous driving mode in accordance with behavior predictions for other road users in the vehicle's vicinity. In particular, the vehicle's onboard computing system may predict whether another road user will perform a “continuing” lane driving operation, such as going straight in a turn-only lane. Sensor data from detected/observed objects in the vehicle's nearby environment may be evaluated in view of one or more possible behaviors for different types of objects. In addition, roadway features, in particular whether lane segments are connected in a roadgraph, are also evaluated to determine probabilities of whether other road users may make an improper continuing lane driving operation. This is used to generate more accurate behavior predictions, which the vehicle can use to take alternative (e.g., corrective) driving actions.

  • Patent number: 11426230
    Abstract: A forceps includes a first portion and a second portion. The first portion includes a shaft, an end effector assembly disposed at a distal end of the shaft, and a drive assembly including a drive bar. The end effector assembly includes jaw members movable between spaced-apart and approximated positions. The drive bar is slidably disposed within the shaft and coupled to the end effector assembly such that translation of the drive bar relative to the shaft moves the jaw members between the spaced-apart and approximated positions. The second portion includes a housing (or portion thereof) and a handle assembly including a movable handle that is coupled to the housing and movable relative thereto between first and second positions. The first and second portions are releasably couplable with one another to operably couple the movable handle with the drive bar such that moving the movable handle actuates the jaw members.

  • Publication number: 20220254971
    Abstract: An inorganic ultraviolet LED device, includes a bracket, a curved lens, a press ring, a wire and an ultraviolet chip. A “T”-shaped recess is formed on the upper end of the bracket. The ultraviolet chip is fixed within the recess and connected to a welding layer at the lower end of the bracket through the wire. The curved lens is placed on a step of the recess. An inclined surface is formed on a contact surface of the step contacting with the curved lens. One end of the press ring is connected to the bracket, and the other end thereof presses against the curved lens. Deformation of the press ring is implemented under a pressure action of a pressure head, thereby implementing high-strength bonding of the device. Self-positioning is achieved through a curved surface of the lens and the contact with the inclined surface of the bracket.

  • Patent number: 11403546
    Abstract: The invention discloses a sewage treatment process fault monitoring method based on fuzzy width adaptive learning model. Including “offline modeling” and “online monitoring” two stages. “Offline modeling” first uses a batch of normal data and 4 batches of fault data as training samples to train the network offline and label the data. After the network training is completed, the weight parameters are obtained for online monitoring. “Online monitoring” includes: using newly collected data as test data, using the same steps as offline training networks for online monitoring. The output result of online monitoring adopts one-hot encoding to realize zero-one discrimination of the output result of online monitoring, so as to realize fault monitoring. The present invention only needs to increase the number of enhanced nodes, reconstruct in an incremental manner, and does not need to retrain the entire network from the beginning.

  • Publication number: 20220137623
    Abstract: To operate an autonomous vehicle, a rail agent is detected in a vicinity of the autonomous vehicle using a detection system. One or more tracks are determined on which the detected rail agent is possibly traveling, and possible paths for the rail agent are predicted based on the determined one or more tracks. One or more motion paths are determined for one or more probable paths from the possible paths, and a likelihood for each of the one or more probable paths is determined based on each motion plan. A path for the autonomous vehicle is then determined based on a most probable path associated with a highest likelihood for the rail agent, and the autonomous vehicle is operated using the determined path.

  • Publication number: 20210382489
    Abstract: Jaywalking behaviors of vulnerable road users (VRUs) such as cyclists or pedestrians can be predicted. Location data is obtained that identifies a location of a VRU within a vicinity of a vehicle. Environmental data is obtained that describes an environment of the VRU, where the environmental data identifies a set of environmental features in the environment of the VRU. The system can determine a nominal heading of the VRU, and generate a set of predictive inputs that indicate, for each of at least a subset of the set of environmental features, a physical relationship between the VRU and the environmental feature. The physical relationship can be determined with respect to the nominal heading of the VRU and the location of the VRU. The set of predictive inputs can be processed with a heading estimation model to generate a predicted heading offset (e.g., a target heading offset) for the VRU.
