Abstract: The present disclosure pertains to a system (10) configured to automatically set the positive end expiratory pressure (PEEP) during mechanical ventilation (800). The system uses a measured relationship between transpulmonary pressure and lung volume (804) to set PEEP (808) such that mechanically assisted breaths are delivered more effectively to open airways (e.g., tidal breaths will be delivered to airways that consist of alveoli that have not contracted or collapsed at the end of expiration) (810). Furthermore, the system is configured to sense (18, 804) when the lungs may be either hyperextended and/or undergoing cyclic atelectasis in order to prevent trauma or injury to the lung's fibrous tissue. The system is configured to perform recruitment and/or continuous monitoring and adjustment of the PEEP setting to maintain an open lung.

Abstract: Techniques described herein relate to lane handling, for instance to enable vehicles to perform turns without colliding into oncoming vehicles and/or bicycles in other lanes. System(s) associated with a vehicle can access sensor data and/or map data associated with an environment within which the vehicle is positioned in a first lane. The system(s) can determine that the vehicle is to perform a turn and a start of a second lane associated with the turn or a merging zone associated with the second lane. The system(s) can determine a location of the vehicle relative to the start of the second lane or the merging zone associated with the second lane and, based partly on the location, can cause the vehicle to merge into the second lane prior to performing the turn.

Also disclosed herein is a texturizing agent comprising an inhibited starch and a non-granular, enzymatically-debranched waxy potato starch.

Abstract: Junction queueing for vehicles is described, in which vehicles may be queued based on arrival time at a junction, position relative to a stopping location at the junction, and/or an amount of time waiting for other vehicles to proceed through the junction (timeout). In some examples, the queue may be first generated based on the arrival times of any other vehicle relative to a particular vehicle generating the queue. The queue may be updated based on arrival times of other vehicles (e.g., after the particular vehicle), whether another vehicle has proceeded out-of-turn (e.g., based on a position at the junction), and/or a timeout for vehicles that wait for others to yield at the junction. In some examples, hysteresis and alterations of the score for safety reasons may alter queue order. The queue may be used to control the particular vehicle to traverse the junction.

Abstract: Techniques are discussed for controlling a vehicle, such as an autonomous vehicle, based on occluded areas in an environment. An occluded area can represent areas where sensors of the vehicle are unable to sense portions of the environment due to obstruction by another object. An occlusion grid representing the occluded area can be stored as map data or can be dynamically generated. An occlusion grid can include occlusion fields, which represent discrete two- or three-dimensional areas of driveable environment. An occlusion field can indicate an occlusion state and an occupancy state, determined using LIDAR data and/or image data captured by the vehicle. An occupancy state of an occlusion field can be determined by ray casting LIDAR data or by projecting an occlusion field into segmented image data. The vehicle can be controlled to traverse the environment when a sufficient portion of the occlusion grid is visible and unoccupied.

Abstract: An electrode system for use in an AC-electrospinning process comprises an electrical charging component electrode and at least one of an AC field attenuating component and a precursor liquid attenuating component. The electrical charging component electrode is electrically coupled to an AC source that places a predetermined AC voltage on the electrical charging component electrode. In cases in which the electrode system includes the AC field attenuating component, it attenuates the AC field generated by the electrical charging component electrode to better shape and control the direction of the fibrous flow. In cases in which the electrode system includes the precursor liquid attenuating component, it serves to increase fiber generation, even if the top surface of the liquid precursor is not ideally shaped or is below a rim or lip of the reservoir that contains the liquid on the electrical charging component electrode.
