Abstract: An obstacle detection system includes a first component and a second component. The motor is configured to move the second component toward the first component. Radio frequency identification tags (RFIDs) are connected to one of the first component and the second component. A controller is operatively connected to the motor and has a transmitter operatively connected to the other of the first component and the second component. The transmitter is operable to create a magnetic field between the first component and the second component. Each of the RFIDs is operable to provide a respective signal in response to the field. The controller is configured to modify power delivery from a power source to the motor when the respective signals received by a receiver change due to at least a portion of the magnetic field being at least partially blocked or attenuated. A method of detecting an obstacle is also provided.

Abstract: An impact beam assembly includes a beam of high-strength steel, and a pair of end brackets constructed of a dissimilar material than the high-strength steel. The brackets are locally deformed onto the beam to thereby surround a portion of the beam. Once deformed, the brackets define a flat section suitable for welding to a vehicle door panel, as well as a section for retaining the beam. The beam can include a surface feature suitable for retaining the beam to the end brackets. A method of reinforcing a vehicle door assembly includes positioning the beam with respect to the end brackets such that the brackets surround a portion of the beam, and then activating a magnetic pulse coil (MPC) to deform an overlapping portion of the brackets onto the beam. The brackets are then attached to a surface of the door assembly to reinforce the door assembly.

Abstract: An assembly includes a first member and a second member spaced from and the first member, with the first member and the second member moveable relative to each other. A shape memory alloy actuator couples the second member to the first member. The shape memory alloy actuator includes a first end and a second end, both attached to the first member, with the shape memory alloy wrapped around a guide device to redirect the path of the shape memory alloy actuator. Having both the first end and the second end attached to the second member doubles the tensile force applied to the second member when the shape memory alloy actuator contracts.

Abstract: A door assembly for a vehicle includes an outer panel configured for defining an exterior surface of the vehicle, and an inner panel matable to the outer panel to define a cavity therebetween. The inner panel includes a lower portion having a first longitudinal axis and a B-pillar assembly extending from the lower portion. The B-pillar assembly includes a casting having an external surface configured for defining the exterior surface of the vehicle, an internal surface spaced apart from the external surface, a length, and a second longitudinal axis. The casting extends from the portion along the second longitudinal axis, and the second longitudinal axis is substantially perpendicular to the first longitudinal axis.

Abstract: The present application is directed at providing a new lasing device having increased production yields over other single mode laser devices. In particular, a semiconductor lasing device is provided having at least two lasing devices formed on a common substrate. The lasing device is arranged so that in use a preferred lasing device is operational and remaining lasing devices are redundant. This redundancy improves the production yield since only one of the lasing devices needs to function correctly as the others are unused.
