Abstract: A rigid wheel (18) or roller for a compactor machine, comprising a drum for contacting material to be compacted. The drum has a profiled outer surface including a first cylindrical portion (27) and a second cylindrical portion (29). The first cylindrical portion has a larger rolling diameter than the second cylindrical portion. An inclined portion (24) extends between the first and second cylindrical portions. The area of contact between the outer surface of the drum and refuse, soil or other material to be compacted varies with the depth of penetration of the wheel into the material. The different rolling diameters within the scope of one wheel gives different ground pressures. This means that the pressure applied to the material for compaction varies depending upon the depth of penetration of the wheel. One benefit of this wheel/roller design is to allow improved go anywhere mobility—high floatation where needed changing to heavy ground pressure where conditions demand.

Abstract: The system contains a plurality of sensors outputting sensor data. A processor is in communication with the sensors to receive the sensor data. A logic system is in communication with the processor. The logic system evaluates a likelihood of a plurality of hypotheses, generates a representation of the likelihood of the plurality of hypotheses in a coordinate system, and connects trajectories between a plurality of discrete hypothesis aspects of the plurality of hypotheses. An output of the processor provides at least one likely outcome and a confidence level for each of the likely outcomes. At least one likely outcome is selected based on contours of the representation of the likelihood to of the plurality of hypotheses in the coordinate system.

Abstract: A dual air cavity roof has a continuous upper cavity which is cooled by fans, while the lower cavity is generally sealed. Preferably the cavities are separated by a radiant barrier. The fans are preferably powered by one or more photovoltaic cells that are also disposed on the roof. The roof can be pre-cooled with cooler night air and fans only activated when necessary to remove heat from the solar load on the upper cavity. When it is desirable to remove heat, the fan speed is optimized in each zone of the roof to enhance the natural convective flow to the optimum level. A radiant barrier can also cover the roof substrate, which is optionally an existing roof that is in need of repair. The roof structure is preferably assembled in parallel modules using insulating support brackets that support the outer surface and the barrier that separates the upper and lower cavity.

The fiber optic phased array also includes phase modulators and a gain adjustment mechanism for altering the phase and the amplitude of the optical signals propagating along the fiber optic amplifiers to compensate for modifications in the phase and amplitude that will be introduced by atmospheric turbulence. Among other things, the amplitude control of the optical signals is not adversely effected by intensity nulls in the reflected wavefront.

Abstract: An optical field sensing system and an associated method are provided that are tolerant of scintillation. The system includes a wavefront sensor that measures gradients across a wavefront at a first resolution defined by the subapertures of the wavefront sensor. The system also includes an intensity sensor that measures the intensity across the wavefront at a higher resolution. The system further includes a wavefront processor that determines respective phases across the wavefront. In addition to the gradients and the intensity measurements, the wavefront processor may determine the respective phases based also upon the noise affiliated with the measurements. In this regard, the wavefront processor may determine the respective phases across the wavefront at least partially based upon the gradients as adjusted by weights that are based upon the intensity measured by the intensity sensor and are influenced by evidence of scintillation.
