Abstract: A bumper protection device for an automobile including a parallel track mounted to an underside of an automobile, a bumper shield continuously disposed atop the parallel track, a pair of spring loaded hinges, a linear actuator, a central processing unit, and a power connector. The bumper shield has an extended position and an alternate retracted position. The central processing unit is configured to activate the linear actuator to transport the bumper shield along the parallel track to the extended position when a user selectively engages an automobile in a parking gear. The central processing unit is configured to activate the linear actuator to transport the bumper shield along the parallel track to the retracted position when the user selectively engages the automobile from the parking gear to an alternate gear.

Abstract: An essentially invisible lace weft hair extension comprising a first layer of lace, extension hair knotted into the first layer to define a weft base, a knot sealant/bonding agent applied to the weft base, and a second layer of lace bonded to the first layer over the weft base. The weft base is double-bleached (both lace and knots), preferably before the knot sealant/bonding agent is applied. Methods for constructing the weft, and for applying the weft to a wearer's scalp using adhesive, are also disclosed.

Abstract: A system comprising a first expandable tubular section and a first expansion bridge coupled to an inner surface of the first expandable tubular section. A base pipe is coupled to the first expandable tubular section and to a second expandable tubular section. A second expansion bridge is coupled to an inner surface of the second expandable tubular section. The system also comprises an expansion cone disposed within and translatable relative to the first expandable section. The expansion cone has an expansion diameter greater than an inner diameter of the first and second expansion bridges and less than an inner diameter of the base pipe.
