Abstract: Techniques for determining a vehicle trajectory that causes a vehicle to navigate in an environment relative to one or more objects are described herein. In some cases, the techniques described herein relate to selectively expanding a tree structure (e.g., a decision tree structure) to efficiently search for simulation data that can be used to evaluate vehicle control trajectories. The tree structure may include state nodes representing observed and/or predicted environment states, and action nodes representing candidate actions the vehicle may take. By selectively and incrementally expanding the tree using estimated state transition probabilities to focus on higher likelihood scenarios, more optimal trajectories can be determined without exhaustively evaluating every possible outcome.

Abstract: Systems and techniques for determining a sideslip vector for a vehicle that may have a direction that is different from that of a heading vector for the vehicle. The sideslip vector in a current vehicle state and sideslip vectors in predicted vehicles states may be used to determine paths for a vehicle through an environment and trajectories for controlling the vehicle through the environment. The sideslip vector may be based on a vehicle position that is the center point of the wheelbase of the vehicle and may include lateral velocity, facilitating the control of four-wheel steered vehicle while maintaining the ability to control two-wheel steered vehicles.

Abstract: Tracking perception and/or planning component decisions may comprise generating a data structure in association with an output determined by a component. This data structure, along with one or more data structures generated in association with other outputs generated by the same or different components of the vehicle, may be used to determine a trace that identifies component(s) that determined outputs that affected a particular component's generation of an output. This trace and/or factors identified by the data structure may be used to detect a problem with a component; identify a component or output therefrom that may be causing an error; determine a portion of a component that has been activated and a frequency associated therewith; and/or visualize operation of the vehicle associated with activation of particular components, among additional or alternate uses discussed herein.

Abstract: Techniques for aggregating costs associated with one or more heat maps to control a vehicle in an environment are discussed herein. A vehicle computing device can implement a model to determine heat maps and respective cost information for different features of the environment based on sensor data. The vehicle computing device can output a planned trajectory for the vehicle based on combining the heat maps. The techniques can also include determining a rationalization or root cause detailing reasons why the planned trajectory was determined.

Abstract: An unmanned aircraft system includes an aircraft control system that enables the safe operation of multiple unmanned aerial vehicles in the same airspace, through the use of a decentralized air traffic management system. The decentralized air traffic management system is robust against loss of communication between the unmanned aerial vehicle and does not require a centralized ground control system to coordinate the vehicles.

Abstract: The present invention provides systems and methods for data storage. A hierarchical storage management architecture is presented to facilitate data management. The disclosed system provides methods for evaluating the state of stored data relative to enterprise needs by using weighted parameters that may be user defined. Also disclosed are systems and methods evaluating costing and risk management associated with stored data.

Abstract: Systems and methods for performing hierarchical storage operations on electronic data in a computer network are provided. In one embodiment, the present invention may store electronic data from a network device to a network attached storage (NAS) device pursuant to certain storage criteria. The data stored on the NAS may be migrated to a secondary storage and a stub file having a pointer pointing to the secondary storage may be put at the location the data was previously stored on the NAS. The stub file may redirect the network device to the secondary storage if a read request for the data is received from the network device.

Abstract: The present invention relates to a medical device which can be used to resect and remove polyps, stones or foreign bodies. It accomplishes this goal by using a variable configuration basket which may act as a snare and a maneuverable basket. The various wires of the variable configuration basket are controllable by the operator.

Abstract: A video recording and playback network comprises a video source, a plurality of recorders, a local server, and a client device. The plurality of recorders records video from the video source. The local server generates a playlist comprising one or more ordered video segments which together cover a desired time range. The playlist associates one of the plurality of recorders with each video segment. The client device plays back video according to the playlist by streaming each video segment, in sequence, from the associated recorder.
