Abstract: The present disclosure is directed to performing one or more validity checks on potential trajectories for a device, such as an autonomous vehicle, to navigate. In some examples, a potential trajectory may be validated based on whether it is consistent with a current trajectory the vehicle is navigating such that the potential and current trajectories are not too different, whether the vehicle can feasibly or kinematically navigate to the potential trajectory from a current state, whether the potential trajectory was punctual or received within a time period of a prior trajectory, and/or whether the potential trajectory passes a staleness check, such that it was created within a certain time period. In some examples, determining whether a potential trajectory is feasibly may include updating a set of feasibility limits based on one or more operational characteristics of statuses of subsystems of the vehicle.

Abstract: A kit for protecting a user's wounded limb from dirt or moisture comprises a tubular waterproof material, a fastener, and a strap. The fastener is fastened around a first end of the tubular waterproof material to form a waterproof sheath. The strap has portions that are adjustably coupled to one another to form a noose around a second end of the tubular waterproof material. The noose is tightened to secure the waterproof sheath to a user's limb. The components of the kit may alternately be provided to the user in partially assembled form, with some of the components being “sized to fit” prior to being given to the user.
