It is herein presented a novel transfer apparatus for a snowmobile, the transfer apparatus comprising a joint part and a support for a wheel. The joint part comprises an attachment hole for a ski bolt between a ski and a ski suspension of the snowmobile and a first coupling member for the detachable attachment of the support for the wheel and the support for the wheel comprises a second coupling member which is configured to connect to the first coupling member such that a detachable coupling is formed for the wheel.

A utility sled is formed from a lightweight material and includes a handle flexibly attached to the front end thereof. The handle includes a hook that is seated within a small opening of the utility sled when not in use. A pair of retractable wheels is attached to an exterior of each sidewall of the utility sled. The sidewalls are biased outward when no load is present. When loaded, the sidewalls advantageously tend to straighten vertically. The formed bottom of the sled includes a plurality of ribs which both add strength to the sled as well as function as sled runners when the wheels are retracted. The ribs operate to reduce friction between the sled bottom and the underlying surface.

The present invention relates to a traction device using a drone and, more specifically, to a traction device using a drone, the device being capable of towing, along the progressing direction of a drone and by the thrust of the drone, an operator operating a drone and a carrier on which the operator rides. The traction device using a drone, of the present invention, can be applied to a moving means and leisure activities by allowing a user operating a drone to move in a flying direction of the drone, thereby enabling utilization of the drone to increase. In addition, the traction device using a drone of the present invention has an ascending and descending operation unit and a forward and backward operation unit, which are respectively formed as a rotational type, such as that of a knob dial, so as to facilitate maintenance of a constant altitude and a constant speed of the drone.

An apparatus and a method for controlling a rear wheel steering (RWS) system, may include determining, by a controller, whether an abnormality occurs in a rear wheel alignment based on information collected from the vehicle; determining, by the controller, a correction amount of the rear wheel alignment for correcting the abnormality occurring in the rear wheel alignment using predetermined data based on one or more of the information collected from the vehicle when the abnormality is determined to occur in the rear wheel alignment; correcting, by the controller, a rear wheel control position determined based on variable information related to an RWS control using the determined correction amount of the rear wheel alignment; and controlling, by the controller, an RWS actuator of the vehicle based on the corrected rear wheel control position, and an apparatus for controlling an RWS system.

Insulated building products, methods and structure using those products are disclosed. The embodiments described include building materials having a core of encapsulated polystyrene (EPS) which is completely coated with a polymer. The polymer coating provides protection and structural integrity to the foam such that structures made of EPS foam can support multiple human beings without incurring damage. Moreover, additional embodiments are provided in which additional structural integrity is provided by affixing one or more rigid materials to the EPS foam prior to coating. The results, as disclosed, are light-weight, portable building structures that provide protection from the weather and that can be easily heated or cooled.

A trailer system for transporting multiple adult passengers and/or supplies over harsh terrain (e.g., snow, ice, wetland, etc.) when towed behind a vehicle. The trailer system includes a cabin, first and second skis, and first and second suspension assemblies. The suspension assemblies connect the skis, respectively, with the cabin. The suspension assemblies incorporate multiple pivot points that effectively isolate the skis from cabin, and promote true tracking of the trailer system relative to the towing vehicle. In some embodiments, the cabin has a highly buoyant construction, allowing the trailer system to float in water.

Sleds and other recreational vehicles rideable or otherwise usable by one or more users with a built-in holder for a smartphone or other camera-equipped device to facilitate taking selfie and/or ahead-looking pictures or video while the one or more users are using the recreational vehicle.

A wheeled device for increasing the mobility of a snowmobile or ski-bound vehicle, wherein the wheeled device, having a cylindrical axle, is attached to the bolt on the interior of a sled ski underneath the snowmobile sled, which raises the skis off the ground and does not increase the snowmobile sled width. The wheeled device surrounds the interior sled ski bolts and nuts thereon and is tightened onto said bolts and nuts by way of a tightening wheel. The snowmobile is thus able to drive on the wheeled devices so that it can conveniently move from one location to another without damaging the bottom of the skis if on rough or unstable terrain.

A microsurgical handle and instrument may include an actuation structure having an actuation structure distal end and an actuation structure proximal end, a plurality of actuation arms of the actuation structure, and an actuation structure base. A compression of the actuation structure may be configured to extend the actuation structure distal end relative to the actuation structure proximal end. A compression of the actuation structure may be configured to expand an extension joint of an actuation arm of the plurality of the actuation arms. A decompression of the actuation structure may be configured to retract the actuation structure distal end relative to the actuation structure proximal end. A decompression of the actuation structure may be configured to collapse an extension joint of an actuation arm of the plurality of actuation arms.

A material handling device is provided. The material handling device includes a bottom, a frame, a wall, an a plurality of wheels. The bottom includes an upper surface and a lower surface. The frame includes an upper surface and a lower surface. The wall surrounds the bottom and the frame, and includes an inner surface, an outer surface and an inner shelf attached to a lower portion of the inner surface. The inner surface includes an upper surface attached to a portion of the lower surface of the bottom, and a lower surface attached to a portion of the upper surface of the frame. Each wheel is attached to the lower surface of the frame.
