Abstract: Disclosed herein are systems, methods, and computer program products for selectively using vehicle trajectories. The methods comprise: receiving a vehicle trajectory (VT) prior to being used to generate motion commands (MCs) for a vehicle; identifying software and/or hardware components of the vehicle that produced data used to generate VT; determining whether a fault condition exists that is associated with VT based on (i) a detection that the software/hardware component(s) did or did not experience a fault or operational condition of a type while producing the data used to generate VT and/or (ii) a detection that VT would or would not cause violation of limit(s) for an operational parameter of the vehicle; selecting VT when the fault condition does not exist or another VT when the fault condition does exist; and causing the motion commands to be generated using VT or the another VT which was selected.

Abstract: A cartridge can comprise a first elastomeric membrane and a second elastomeric membrane, and portions of the elastomeric membranes which are sealed to each other can circumscribe unsealed portions of the membranes. In a resting state, the unsealed portion of the first elastomeric membrane abuts or is proximate to the unsealed portion of the second elastomeric membrane. One or more reagents can be injected between the unsealed portions of the first and second elastomeric membranes to push the unsealed portions apart from each other in this region of the membranes. The unsealed portions can be sequentially pushed apart in downstream regions to form a channel between the elastomeric membranes. Positively displaced fluid pushes the unsealed membrane portions apart to a volume that conforms to the volume of the fluid to minimize or prevent dead volume in the channel and thus minimize or prevent air bubbles in the fluid.
