Abstract: An asymmetrically shaped handheld controller and harness assembly for securing safety accessories to the handheld controller for electric personal mobility devices (EPMDs), and a kit thereof, generally includes an asymmetrically shaped handheld controller, an adjustable and a flexible strap that is perforated along its length, releasable connectors that secure the flexible strap about the controller, and headlight and taillight assemblies. The flexible strap conforms to at least three sides of the controller and has an oblong aperture sized to allow access through the strap to a thumb control on the controller. Stabilizing side members may connect accessories including horns, bells, and mirrors to the flexible strap. The controller is configured to wirelessly connect to EPMDs. The taillight operates as a brake light.

Abstract: This invention relates to hinged derail assemblies used in the railroad industry for derailing a wheel of an undesirably moving railed vehicle. The hinged derail assembly includes a base that is positioned adjacent one rail of a pair of railroad rails. A derail shoe is pivotally mounted on the derail base and is moveable between a derailing position and an inoperative position. In the present invention a biasing member, such as a torsion spring, is secured to both the base of the hinged derail assembly and the derail shoe. The spring provides upward lifting force whether the derail shoe is in the inoperative position or in the derailing position. This lifting force assists the worker in the manual lifting of the derail shoe. The invention also relates to a method of constructing the hinged derail wherein the torsion spring is installed when the derail shoe is generally upright.

Abstract: This invention relates to hinged derail assemblies used in the railroad industry as a safety device for derailing a wheel of an undesirably moving railed vehicle, such as a railroad freight car. The hinged derail assembly includes a base that is rigidly mounted on a pair of spaced railroad ties and is operatively positioned adjacent one rail of a pair of conventional railroad rails. A derail shoe is pivotally mounted on the derail base and is moveable between an operative or derailing position and an inoperative position when the derail shoe is moved away from the rail. When the derail shoe is on the rail, a deflecting member on the shoe is positioned to angularly deflect a wheel of the freight car or the like which is undesirably rolling along the rail. This causes the derailing of the wheeled vehicle and prevents harm to things or personnel in the area.

Abstract: Improved lightweight and ultra-lightweight portable derails are disclosed. A portable derail for installation on railway track to prevent a railcar or locomotive from passing beyond a fixed point, thereby protecting workmen and equipment against accidents, the derail being very lightweight and portable so a workman can easily carry it from one location to another, and yet being designed to function effectively under severe loading conditions and resist any tendency to slide along the rail when subjected to impact.
