System and methods for latency reduction for fuse reload post reset
A new approach is proposed that contemplates systems and methods to support post reset fuse reload for latency reduction.

When other components of the electronic device need to access these values, the other components will check the load registers first. If it is determined that the valid indicator of the load registers is set, the stored values are read from the load registers instead of from the fuses. If the valid indicator of the load registers is not set, the values are loaded again from the fuses into the load registers. |

Lead edge offset correction for intermediate transfer drum imaging
An apparatus and method for compensating for variation of the image placement for each color station in an intermediate transfer drum system. A sensor detects the image placed by the previous station and triggers the imaging on the drum such that it properly registered to the previous image. However, the variation of the drum's radius results in runout which creates an error in the image placement, since the surface drum travel will be larger or smaller than expected. The method to correct for a lead edge offset for radial runout involves dividing the drum into regions and calculating an offset center of each region. As the drum transitions from region to region the offset value is updated to determine when to start imaging for proper placement on the sheet. The offset can be derived from the image runout to find the distance traveled from the transfer point or can be measured directly from color-to-color registration variation. |

The pivot joint assembly includes a housing with an opening which extends along an axis. A bearing is received in the opening and which has a cylindrical outer surface that is in slidable contact with another surface so that the bearing can slide in an axial direction relative to the housing. The bearing has a curved inner bearing surface. The pivot joint assembly also includes an inner ring with a curved outer surface that is in slidable contact with the curved inner bearing surface of the bearing so that the inner ring can rotate and articulate relative to the housing. |

Locking mechanism for two telescoping poles of a power tool
A power tool is provided with a telescopic pole including a first pole configured to telescopingly move in an out of a second pole. A locking mechanism is provided including a first section configured to connect to the second pole and a second section configured to connect to the first pole. The first section includes a sheath mountable on and surrounding at least part of the second pole, a resilient tab connected to the sheath, and a catch formed on the tab. The catch is configured to locate within the recess of the second pole when the sheath is mounted on the second pole. |

Hybrid washer
A hybrid washer has an essentially disk-shaped body having an outer ring, an inner ring, and a bore extending through the inner ring. The outer ring has an engagement surface having a plurality of wedges with each wedge having a raised edge that extends radially and perpendicularly from a longitudinal axis projecting through the bore. The inner ring has a pair of spaced-apart essentially flat surfaces in overlying relation with one another. The wedges form a plurality of crests contoured to frictionally engage a mating surface from a locking washer to fix the locking washer against the hybrid washer. |

Fastener
A nut-and-bolt fastener is provided. The nut and bolt are configured with a plurality of interlocking teeth that provide unidirectional travel of the nut with respect to the bolt. In particular, the configuration of the teeth arrest separation of the nut from the bolt while permitting the nut to move toward the head of the bolt into a fastened engagement. The teeth are non-helical and arranged concentrically around the longitudinal axis in evenly-spaced steps or segments along the longitudinal axis and around the shaft of the bolt and bore of the nut. Integral winged washers are provided on the bolt head as well as on the nut. Variations with different rake angles of the teeth as well as an expandable nut are also provided. |

Temporary fastener for structures
The present invention concerns a fastener (110) for the temporary assembly of at least two previously drilled structures (112) comprising: a hollow body (122) comprising a bearing surface (40); elastic clips (24) which are movable relative to the body and which form a projection relative to the bearing surface; a spacer (26) around which the elastic clips are positioned; a connecting element (130), extending within the body and secured to the elastic clips (24); and an actuating element (132) linked to connecting element by a thread/tapping (67, 84). The connecting element is traversed by a lateral opening (70) axially extended between two closed ends (72, 74); and the fastener also comprises a transverse stop (28) secured to the spacer, the said stop being capable of sliding between the axial ends of the said lateral opening. |

Removable plugs for furniture, systems including such plugs, and methods of their use
A removable plug is disclosed for concealing a bore in a piece of furniture, the plug includes a body configured to fit within the bore. A retaining portion of the body is configured to be of adjustable diameter such that a user can cause an increase in the diameter of the portion to create an interference fit between an outer wall of the body and an inner wall of the bore, thereby retaining the plug removably within the bore. Systems and methods that utilize the removable plug are also disclosed. |

Gas core vortex ring generator
A method is provided for producing a vortex ring in a liquid medium. The method includes concatenating pairs of insulated anode and cathode rings into a stack; inserting the stack into a vertically oriented chamber; disposing a cylindrical cavity below the chamber; inserting a piston into the cavity; connecting the chamber to the medium; and raising the piston to displace the medium while the stack produces an annular bubble that induces the vortex ring. In particular, the medium is water and the stack separates the medium into hydrogen and oxygen gas. |
