Abstract: An exemplary embodiment of the present disclosure provides a device for securing a load, the device comprising a sled, a snubber, and a wedge. The sled can be configured to be coupled to the load. The snubber can be coupled to the sled and configured to be inserted into a chamber. The snubber can comprise a slot. The snubber can be configured to move between a contracted position and one or more expanded positions. The wedge can be configured to be inserted into the slot in a distal direction to cause the snubber to transition from the contracted position to the one or more expanded positions. The snubber can form an interference fit with an internal wall of the chamber when in a first expanded position of the one or more expanded positions to fix the location of the load relative to the chamber.

Abstract: A system and method for parallel-beam scanning a surface. An energetic beam source emits an energetic collimated beam which is received by an optical device, comprising: one or more optical media, operable to receive the emitted beam, such as two pairs of coordinated mirrors or a right prism, and at least one actuator coupled to the one or more optical media, and operable to rotate each of the one or more optical media around a respective axis to perform a parallel displacement of the beam in a respective direction, wherein the respective direction, the beam, and the respective axis are mutually orthogonal. The optical device is operable to direct the beam to illuminate a sequence of specified regions of a surface.

Abstract: An article of headwear comprising a substantially circular body securably attached and integral with an annular elasticized absorbent sweatband. The body is sized such that, when the sweatband is fitted over the wearer's forehead, the body forms a cap snugly fitting over the wearer's head. The article of headwear may include a tail piece securably attached to and integral with the rear of the sweatband. Alternatively, the tail piece may be continuous with the body. When the tail piece is included and the headwear is worn, the tail piece drapes down the back of the wearer's head to the shoulders, and extends substantially from the rear of one earlobe to the rear of the other earlobe.
