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: Systems and methods for pre-tuning a main Nuclear Quadrupole Resonance (NQR) probe using a forward sensing probe include a determination of an amount of resonance detuning of the forward sensing probe caused by a moving object entering a field of view of the forward sensing probe. The amount of resonance detuning is used to pre-tune the main probe such that when the moving object enters a field of view of the main probe, the main probe will move back into tune while delivering optimal power to the object for measurement and identification of a material therein.

Abstract: A method and apparatus for automated valve spring assembly includes a head assembly with elongated passageways that movably support a pair of retainer keys. A pair of control members selectively close off the passageways. The head assembly further includes a moveable divider plate and a pair of jaws. A push member or rod closes off the passageways by shifting the control members upon movement of the pushrod. The pushrod also slides the retainer keys such that the retainer keys contact tapered inner surfaces of the jaws and rotate the jaws outwardly. The retainer keys are thereby axially positioned relative to the end of a valve stem. The retainer plate is then retracted, and the jaws shift inwardly and push or position the retainer keys on the valve stem.
