System and method for determining exact location results using hash encoding of multi-dimensioned data
Aspects of the present invention are directed to system and methods for optimizing identification of locations within a search area using hash values. A hash value represents location information in a single dimension format. Computing points around some location includes calculating an identification boundary that surrounds the location of interest based on the location's hash value. The identification boundary is expanded until it exceeds a search area defined by the location and a distance. Points around the location can be identified based on having associated hash values that fall within the identification boundary. Hashing operations let a system reduce the geometric work (i.e. searching inside boundaries) and processing required, by computing straightforward operations on hash quantities (e.g. searching a linear range of geohashes), instead of, for example, point to point comparisons. |

Dual/multi-mode processor pipelines sampling
Embodiments are directed to methodologies for efficiently sampling data for analysis by a pipeline analysis algorithm. The amount of sampled data is maximized without increasing sampling overhead by sampling “non-pipeline activity” data if the subject pipeline is inactive during the sampling time. The non-pipeline activity data is selected to include overall system information that is relevant to the subject pipeline's performance but is not necessarily dependent on whether the subject pipeline is active. In some embodiments, the non-pipeline activity data allows for confirmation of a pipeline performance characteristic that must otherwise be inferred by the subsequent pipeline analysis algorithm from data sampled while the pipeline was active. In some embodiments, the non-pipeline activity data allows the pipeline analysis algorithm to analyze additional performance characteristics that cannot otherwise be inferred from the data sampled while the pipeline was active. |

Lodged projectile removal charge
A process that uses a lodged projectile removal charge (LPRC) apparatus to remove a projectile jammed in a cannon's gun tube. The LPRC is positioned coaxially and offset from the projectile, and the gun tube is filled with water. The charge is detonated producing a shock wave that disintegrates the LPRC apparatus and pressurizes the water. The pressurized water produces a radial hydraulic force against an interior wall of the gun tube, an axial hydraulic force against the projectile pushing the projectile toward the chamber, and produces an opposing expansion of explosive gases that blasts out most of the water in the gun tube. The process is less likely to damage the gun tube. The LPRC may be made using a 3D printer. |

Clamp having a clamp band and a pre-positioner
The invention relates to a clamp, comprising a clamp band and a pre-positioner, wherein the pre-positioner is designed as a supporting band, which has a partial-circle-shaped region, which extends over more than 180°. In order to enable simple production and to prevent loss of the pre-positioner, the supporting band has, at each end thereof, a fastening region bent in relation to the partial-circle-shaped region, wherein the fastening regions are fastened on the same side of the clamp band. |

Three piece pipe coupling
A preassembled pipe coupling and method for joining pipe segments in an end-to-end relationship. The coupling (100) includes three identical housing segments (110) joined end to end. Each housing segment (110) includes a pipe engagement surface defining a radius of curvature. The radii of curvature of the three housing segments (110) are identical. The third housing segment is connected to the first and second housing segments to define a first configuration and a second configuration of the coupling, in which the radii of curvatures are the same in the first and second configurations. In the first configuration, the three housing segments (110) are radially located about an annular gasket (400) to permit insertion of the pipe segment into the gasket (400). In the second configuration, the three housing segments are radially located about the annular gasket such that the gasket is compressed to form a fluid tight seal and the pipe engagement surfaces engage the outer surface of the pipe segment. |

Band tightening assembly
A band tightening assembly includes a guide that is positionable against HVAC ducting. The guide slidably engages a band extending around the HVAC ducting. The guide has a first arm extending along a longitudinal axis that is oriented perpendicular to a second arm such that the first and second arms form a plus. A collar is coupled to the guide and the collar is positioned on the first arm. The collar is oriented to extend along an axis that is offset 4.0 degrees from the longitudinal axis of the first arm. A shaft is rotatably positioned in the collar and the shaft has a rotational axis that is aligned with the axis of the collar. The shaft has a slot therein for insertably receiving the band. The shaft has an engaging well for receiving a socket drive on a power tool. Thus, the shaft is rotated about the rotational axis when the power tool is turned on to tighten the band around the HVAC ducting. |
