    Abstract: A cold-formed, raised-center axle for a heavy-duty vehicle includes a central tube having a pair of ends, a pair of spindles attached to the central tube ends, and a wall thickness of from about 0.500 to about 0.625 inches. A hump is formed in the center portion of the tube and includes compressive residual stresses in its bottom portion when the axle is in an in-service position. A method for forming the raised-center axle includes the steps of providing a substantially straight axle, inserting the axle into a press, over-forming a hump in the axle in the direction such that camber is induced in the axle, and forming the axle in a second direction, thereby substantially removing the camber and replacing a detrimental residual stress state in the humped portion of the axle with a beneficial residual stress state.

    Abstract: Systems and methods for performing processing of communications signals on multi-processor architectures. The system consists of a digital interface that translate numbers that represent a waveform in some format to analog signals for use in transmission and translating analog signals to numbers representing those waveforms in some format that can be processed by the commodity digital hardware and software combination. The digital hardware and software incorporates parallel hardware and software that can process single or multiple streams and multiple processing steps as required for the communications system in any combination. In the examples, the use of general purpose graphics processing units (GPGPUs) is illustrated, but the system is not necessarily limited to such an implementation. The system is highly scalable and modular for addressing a wide range of radio requirements, preferably using commodity components.

    Abstract: A movable subframe for a tractor-trailer includes a pair of elongated spaced-apart main members extending longitudinally relative to the tractor-trailer, at least one cross member extending between and being attached to the main members, and a retractable pin mechanism for selectively securing the position of the subframe relative to a body of the tractor-trailer. At least one of the main members includes at least one opening for receiving a pin of the retractable pin mechanism. The main member opening is formed in a shape, such as a D-shape, which reduces or minimizes distortion of the main member adjacent the top of the opening that is associated with forming of the main member.
