Reconfigurable hardware structures for functional pipelining of on-chip special purpose functions
A method and apparatus for reconfiguring hardware structures to pipeline the execution of multiple special purpose hardware implemented functions, without saving intermediate results to memory, is provided. Pipelining functions in a program is typically performed by a first function saving its results (the “intermediate results”) to memory, and a second function subsequently accessing the memory to use the intermediate results as input. Saving and accessing intermediate results stored in memory incurs a heavy performance penalty, requires more power, consumes more memory bandwidth, and increases the memory footprint. Due to the ability to redirect the input and output of the hardware structures, intermediate results are passed directly from one special purpose hardware implemented function to another without storing the intermediate results in memory. Consequently, a program that utilizes the method or apparatus, reduces power consumption, consumes less memory bandwidth, and reduces the program's memory footprint. |

Maximum and minimum horizontal stresses, and horizontal to overburden stress ratio, are estimated using radial profiles of shear moduli. Inversion enables estimation of maximum and minimum horizontal stresses using radial profiles of three shear moduli associated with an orthogonal set of axes defined by the three principal stress directions. Differences in the far-field shear moduli are inverted together with two difference equations obtained from the radial profiles of the dipole shear moduli C44 and C55, and borehole stresses in the near-wellbore region. The horizontal to overburden stress ratio is estimated using differences in the compressional, dipole shear, and Stoneley shear slownesses at two depths in the same lithology interval where the formation exhibits azimuthal isotropy in cross-dipole dispersions, implying that horizontal stresses are nearly the same at all azimuths. The overburden to horizontal stress ratio in a formation with axial heterogeneity may also be estimated using the far-field Stoneley shear modulus C66 and dipole shear modulus C55 together with the radial variation of the dipole shear modulus C55 caused by near-wellbore stress concentrations. |

Method of determining when tool string parameters should be altered to avoid undesirable effects that would likely occur if the tool string were employed to drill a borehole and method of designing a tool string
A method of determining when tool string parameters should be altered to avoid undesirable effects that would likely occur if the tool string were employed to drill a borehole includes, modeling portions or an entirety of the tool string in the borehole under steady state loading conditions, identifying deflections of the tool string with the modeling when buckling would occur for specific tool string parameters, and calculating whether whirl exhibiting similar deflections of the tool string to those identified during buckling would be undesirable. |

Extendable / retractable ladder
An extendable/retractable ladder assembly includes a first stile and a second stile and a plurality of rungs extending therebetween. Each stile may comprise a plurality of columns disposed in a nested arrangement for relative axial movement in a telescopic fashion. A connector assembly connects the rungs to respective columns in the first and second stiles. The ladder has improved manufacturability since connector assemblies may be assembled before connecting the rungs to respective columns. The standing surface of the rungs may be angled such that it is rotated towards horizontal when the ladder assembly is leaned against a wall. A latch assembly may be used to selectively lock relative axial movement between adjacent columns. The latch assembly includes a locking pin assembly comprised of a central post and an outer metal sleeve. An air damper may also be used to control airflow through the columns. |

Barrier with region of increased thickness
A barrier includes a main body, a first edge region, and a second edge region. The first edge region can include a first bulging element, and the second edge region can include a second bulging element. The first and second edge regions can be on opposite sides of the barrier and can extend substantially parallel to each other. The main body of the barrier can include one or more regions of increased thickness. The region(s) of increased thickness can be in an intermediate location between the first bulging element and the second bulging element. The region(s) of increased thickness can be spaced from the first edge region and the second edge region such that the region(s) of increased thickness do not contact the first bulging element or the second bulging element. The main body, the first bulging element, and the second bulging element can be configured to be rolled. |

Soft close hinge assembly
A hinge assembly includes a lever arm and a channel connected to the lever arm. The channel is adapted to be connected to an associated appliance door. A control link is pivotally connected to the lever arm. A slide body includes an inner end connected to the control link. The slide body is adapted for sliding movement in response to pivoting movement of the channel relative to the lever arm between a first (door-closed) position and a second (door-opened) position. A spring resiliently biases the channel toward the first position. A snubber system includes at least one snubber with a piston that is biased to an extended position and moveable to a retracted position against a fluid or other damping resistance during movement of the slide body away when the channel moves from the first position to the second position. |

Bi-fold door latch assembly
A latch assembly connected to the drive unit of a bi-fold door for retaining the bi-fold door secure to a building has elongated straps attached to rotatable latch drums mounted on the outer ends of the drive shaft of the drive unit. Lift drums powered by a motor driven gearbox raise and lower the bi-fold door. Latch assemblies having springs attached to the straps maintain tension on the straps during the opening and closing of the bi-fold door. |
