Abstract: A suspension system for a motorized or non-motorized roller board includes a truck center housing, a pair of truck wings disposed on opposing sides of the truck center housing, and a pair of wheels connected to the respective pair of truck wings. The truck center housing is configured to engage with a truck assembly coupled to a deck of the roller board. The truck center housing defines a pivot axle cavity that houses a pivot axle, a pivot axle shaft and a pair of torsional springs disposed on each side of the pivot axle coupled to the deck of the roller board. The pair of truck wings includes a front cavity that receives the corresponding torsional spring and a wheel shaft that couples with the pair of wheels. The pair of torsion springs dampen the load of the roller board when a force is exerted on the wheels.

Abstract: In one aspect a method of fabricating an n-doped strained germanium (Ge) film is disclosed, which includes depositing a strained Ge film on an underlying substrate, implanting at least one electron-donating dopant in the Ge film, and exposing the implanted Ge film to one or more laser pulses having a pulsewidth in a range of about 1 ns to about 100 ms so as to generate a substantially crystalline strained Ge film. In some embodiments, the pulses can cause melting followed by substantial recrystallization of at least a portion of the implanted Ge film. In some embodiments, the resultant Ge film can have a thickness in a range of about 10 nm to about 1 microns.

Abstract: In one aspect, a method of processing a semiconductor substrate is disclosed, which comprises incorporating at least one dopant in a semiconductor substrate so as to generate a doped polyphase surface layer on a light-trapping surface, and optically annealing the surface layer via exposure to a plurality of laser pulses having a pulsewidth in a range of about 1 nanosecond to about 50 nanoseconds so as to enhance crystallinity of said doped surface layer while maintaining high above-bandgap, and in many embodiments sub-bandgap optical absorptance.

Abstract: This invention includes an adjustable boat top, that can be lowered in order to permit the boat to travel under bridges and other obstructions that might otherwise preclude the passage or movement of the boat. The boat top is lowered as the boat top slides forward to the front to the boat. The top frame of the boat top is supported by a forward frame and a rearward frame, which may be connected to pivots on the deck surface. In lowering the boat top, the pivots are unlocked so that the forward frame and rearward frame can pivot forward. In a preferred embodiment of the invention, the raising and lowering of the boat top uses a piston assist, but the raising and lowering of the boat top can also be done manually. Preferably, the area of the boat from the pivots out to the side of the boat are not impeded by the boat top in either raised or lowered positions.
