Abstract: An energy absorber according to various embodiments can include a structure having a predetermined cross-sectional profile. A hollow profile is formed within the structure. The pre-determined cross-sectional profile of the structure is configured based on a deceleration-time profile that includes a first period and a second period. The first period is defined by a substantially sharp and linear increase in magnitude of the deceleration of an impact until a maximum deceleration value is achieved. The second period is defined by a rapid decrease in the magnitude of the deceleration.

Abstract: A method for communicating parking space availability for a parking facility. A vehicle-based communication link is established between a remote infrastructure and a user interface device. A parking facility is selected utilizing the user interface device. The selected parking facility is communicated to the remote infrastructure from the user interface device via the vehicle-based communication link. Parking space availability within the selected parking facility is determined by the remote infrastructure. The parking space availability of the selected parking facility is communicated from the remote infrastructure to the user interface device. The parking space availability is determined by the remote infrastructure as a function of crowd sourcing data obtained for the selected parking facility, historical parking data of the selected parking facility, parking availability data of parking facilities proximate to the selected parking facility, and direct parking space sensing by a respective parking facility.

Abstract: A method of laser welding a workpiece stack-up includes directing a laser beam at a top surface of a first metal workpiece to form a key-hole that entirely penetrates the workpiece stack-up, including an underlying second metal workpiece, so that the keyhole reaches a bottom surface of the second metal workpiece. A zone of negative pressure established under the bottom surface of the second metal workpiece extracts vapors that are produced by the laser beam. The vapors, in particular, are extracted from the bottom surface of the second metal workpiece through the keyhole. A bottom workpiece holder that supports the bottom metal workpiece during laser welding may be constructed to establish the zone of negative pressure.

Abstract: A system and method for stabilizing the molten pool in a laser welding operation by suppressing a laser-induced plume which occurs when zinc coated steels are laser welded. The plume is a result of vaporization of zinc, and the zinc vapor in the plume disturbs the molten pool and causes blowholes, spattering and porosity. The stabilization is achieved by applying a gas such as air through a nozzle to the weld area, where the gas has sufficient velocity and flow rate to blow the zinc vapor away from the molten pool. Dramatically improved weld quality results have been demonstrated. Configuration parameters which yield optimum results—including gas flow rate and velocity, and nozzle position and orientation relative to the laser impingement location on the steel—are disclosed.

Abstract: A method for treating a cast iron workpiece to increase a useful life thereof includes machining the workpiece to provide a finish surface thereon and deforming the finish surface of the workpiece by rubbing the finish surface against a blunt tool (80,80′), thereby forming a nanocrystallized surface layer (70). The workpiece is nitrocarburized, the nanocrystallized surface layer accelerating diffusion of nitrogen atoms and carbon atoms therethrough. The nitrocarburizing taking place: i) if the workpiece is stress relived prior to machining, for about 1 hour to about 2 hours at a temperature ranging from about 550° C. to about 570° C., or ii) if the workpiece is not stress relieved prior to machining, for about 5 hours to about 10 hours at a temperature ranging from about 370° C. to about 450° C. The nitrocarburizing renders the nanocrystallized surface layer into i) a friction surface, or ii) a corrosion-resistant surface.

Abstract: A method for manufacturing an inner door panel for a vehicle side door that employs a die casting process. The method includes providing a die cast mold having opposing mold halves that combine to define a die cavity configured to provide the inner door panel having an integrated impact beam. The mold cavity also includes channels that form a runner and gating system that causes the molten material to form an outer frame defining a central opening that allows the mold halves to be separated when the door panel has hardened within the mold.
