  • Patent number: 12093060
    Abstract: A vehicle and method of control comprising generating a geometric control envelope in a geometric space of operation points defined by a number of control aspects, the envelope having vertices representing maximum values of the control aspects, and determining a desired operation point in the geometric space representing a control input. Further, the method includes if the desired operation point is outside the envelope, scaling up a first one of the control aspects by a first factor, determining an effective operation point in the envelope geometrically closest to the desired operation point, scaling down all of the control aspects by a second factor inverse of the first factor, and instructing the propulsion mechanisms to propel the vehicle according to the effective operation point.

  • Patent number: 5224241
    Abstract: A gate hinge member is designed for attachment to a metal T-post fence post. The gate hinge comprises at least one pair of first and second L-shaped hinge members, which are secured by means of a U-shaped fastener to the T-post in a tight wedged relationship. The spacing between the hinge members is selected to accommodate a hinge pin, which is passed through a pair of spaced holes in hinge-pin holding plates of the first and second hinge members. The hinge-pin holding plates extend outwardly perpendicular to the T-post. The hinge pin is adapted to be passed through a mating cylindrical hinge member on the gate to pivotally secure the gate in place between the hinge members. After assembly, the hinge pin is releaseably secured in place by means of cotter pins passed through holes adjacent each of the ends of the hinge pin. The gate hinge may be placed in any vertical position on the face of a T-post, and cannot accidently be dismantled.

  • Patent number: 5046705
    Abstract: A hollow T-shaped wedge member is used for attaching a rectangular collar to a T-post fence post for utilization in conjunction with a bracing system for fences made from such T-posts. The wedge member is shaped to straddle the rear leg of the T-post to produce a wedging engagement between the rear of the front face of the post and the inside of a collar placed over the post. The wedge tightly holds the collar wedged onto the T-post, and aligned with it, and includes a provision for inhibiting withdrawal of the wedge once it is in place.

  • Patent number: 4979724
    Abstract: A double action expansion wedge is disclosed for attaching a collar to a T-post fence for utilization in conjunction with a bracing system for fences made from such T-posts. A hollow collar member has internal dimensions selected to slide over the posts, so that the collar can be positioned vertically between the lugs of the post at a desired location. The double action expansion cam wedge secures the collar between adjacent lugs on the post by tightly wedging the collar and post together. The double action expansion causes the top edge of the collar and the bottom edge of the collar both to be wedged against the post to hold the collar in alignment with the post.
