Abstract: An aspect of the disclosure relates to a data processing system, including: an input medium configured to include a first set of blocks of data including a first set of block of compressed data and a first set of metadata, respectively; an output medium configured to include a first set of blocks of decompressed data each having a predetermined number of decompressed elements; and a set of single instruction multiple data (SIMD) processors configured to: access the first set of blocks of data from the input medium, respectively; decompress the first set of blocks of compressed data to generate the first set of blocks of decompressed data based on the first set of metadata, respectively; and provide the first set of blocks of decompressed data to the output medium, respectively.

Abstract: There is provided a telescoping boom system for an excavating apparatus which includes a linkage member having a pivot segment and lever segment pivoted about a rotating fixed boom. A first hydraulic cylinder is coupled from the fixed boom to the pivot segment. A second hydraulic cylinder is coupled from the lever segment to a retractable outer boom. The first hydraulic cylinder extends to rotate the pivot segment away from a proximate end of the fixed boom, thus forcing the lever segment to rotate towards the proximate end of the fixed boom. The second hydraulic cylinder retracts and combines with the extension force of the first hydraulic cylinder across the linkage member to provide a retraction force to the outer boom.

Abstract: Apparatus, for the remote control of a carrier vehicle from the cab of an excavator which is rotatably mounted upon the back bed of the carrier vehicle through a center pin assembly, is accomplished with a hydrostatic pump operably connected to the crankshaft of the carrier engine. Electric controls in the excavator cab connect to the pump which selectively directs fluid to a motor which rotates a first gear which meshes with a second gear fixed to the carrier vehicle drive shaft. In alternate embodiments, the motor connects to a power take-off on the transmission. Carrier steering, braking, and throttle functions are also remotely controlled at the excavator cab through a combination of electric and hydraulic controls with the electric wires extending from the electric controls in the excavator cab, through a slip ring on the center pin assembly and to the respective function controls at various sites on the carrier vehicle.
