Abstract: A brushless counter-rotating electric apparatus, motor, wheel hub motor, and associated vehicle includes a brushless counter-rotating electric motor that has oppositely rotating armature and stator components, oppositely rotating armature and stator output drives and, when associated with a vehicle, a control assembly for speed-on/off control of the motor and a portable electric power supply.

Abstract: An enhanced counter-rotating electric motor and an associate propulsion system for use with a water-vehicle includes a motor housing, a stator within the housing that rotates about a central axis in one direction, an armature within the stator that rotates about the central axis in an opposite direction from the stator, a first axel that is secured to the stator and extends out from the housing, a second axel that is secured to the armature and extends out from the housing, water-tight rotational seals about each of the two axels, a centrifugal-force-balancing electrical connection mechanism that supplies functioning electrical communication between the motor and external electrical circuitry while operating the motor, and a propeller secured to each said axel.

Abstract: A system and method are disclosed for back up control of a towed-vehicle. The system may include a back up detector, at least one misalignment sensor, a controller, and a misalignment responder. The misalignment responder turns the steering wheel of a towed-vehicle. The system may further include a wireless transmitter to communicate signals between a towing-vehicle and the towed-vehicle. A misalignment signal may be produced by the misalignment sensor when a relative angle between the towing-vehicle and the towed-vehicle exceeds a relative angle threshold. The system may further include a monitoring device in the towing-vehicle to provide an indication of jackknifing and that a towed-vehicle's battery power is low.

Abstract: A vehicle, when equipped with the “Vehicle, collapsible room extensions” system, is provided with additional living or working space. The increased size now available allows the never before possible, addition of totally independent room(s). The room(s) panels, i.e., floor, walls and ceiling, are all substantially hinged to each other at the edges. When hinged opened, a standard looking ridged material room is created. When folded, collapsed in to each other, the panels are reduced to a very thin flat stack, facilitating compact storage for traveling. This stack is attached and transported on the exterior of the vehicle. No part of the “Vehicle, collapsible room extensions” unit is projected in to the vehicle, this allows unobstructed full use of the original vehicles inside space while traveling. Traditional slide outs, do obstruct, restrict and hamper the original vehicles usable interior space.

Abstract: A multi-level recreational vehicle having a body chassis, with side walls, wherein the body chassis is supported on frame rails, wherein the recreational vehicle comprises a lower level having a floor and a ceiling, wherein the lower level floor has a walking portion proximate the frame rails; an intermediate level having a floor and a ceiling, wherein the intermediate level floor staggers with the lower level ceiling; and an upper level having a floor, wherein the floor comprises a deck for recreational or leisure purposes, including hot tubing. Peripherally bordering the upper level is a collapsible railing, wherein the collapsed railing is received by sleeves on or in the side walls of the recreational vehicle.

Abstract: A prefabricated wall insert unit is disclosed for rapid installation in a wall having an outer surface, an internal space, a ceiling plate, and a floor support. When installed, an exterior assembly, with upper and side perimeter attachment areas, projects away from the outer wall surface. A header is fastened to the exterior assembly proximate the upper perimeter attachment area and is within the wall internal space immediately below the ceiling plate. At least two side support members are fastened to the upper support member and to the exterior assembly proximate the side perimeter attachment areas. When installed in the wall, the header and each said side support member are within the wall internal space and each side support member extends from the header to proximate the wall floor support.
