Abstract: Embodiments are directed toward a burn bucket. The burn bucket preferably includes a body, a door moveably coupled to the body, and a lifting machine interface coupled to the body. The body preferably defines an inner burn space. The lifting machine interface is preferably configured to receive a portion of a machine that tilts the burn bucket to transition the burn bucket between a closed configuration in which the door is closed and a dumping configuration in which the door is open to facilitate dumping burnt material out of the inner burn space.

Abstract: Embodiments are directed to an expandable shelter. The shelter may include a main box, a slide box, and a skirt. The main box may have a side opening. The slide box may be slidably coupled to the main box, with the slide box being slidable at least partially through the side opening of the main box. The skirt may be slidably coupled to the slide box, with the skirt being vertically slidable relative to the slide box.

Abstract: Techniques for improving safety at railroad track crossings are described. Example embodiments provide a train detection and collision avoidance system configured to detect potential collisions between vehicles (e.g., cars, trucks, motorcycles) and trains. The system detects potential collisions based on location information obtained by tracking modules installed in or carried by the trains and vehicles. When a potential collision between a vehicle and a train is detected, the train detection system alerts an operator of the vehicle and/or the train, so that the operator can take steps to avoid the collision. The operator may be alerted in various ways, including by audio, visual, or tactile output.

Abstract: A floatable boat ramp is disclosed including a plurality of hollow planks arranged parallel to one another such that the upper surfaces thereof define a drivable surface. A plurality of flexible channels couple cavities defined by adjacent planks of the plurality of hollow planks to one another a first end plank defines one or more openings to allow inlet and outlet of air and water in order to cause the boat ramp to sink or float. The interior cavity of the planks may be divided into right and left hand portions. Left and right hand channels coupled the right and left hand portions, respectively, of adjacent planks to one another. A second end plank includes a continuous cavity and allows fluid communication between left and right hand portions of the other planks. The planks may be coupled together by cables extending through sleeves rotatably mounted to the ends thereof.

Abstract: A snow flap for a snowmobile functions as a removable snow shovel blade. The handle may be used as a pivot attachment for the blade to the snowmobile and may be alternatively attached to the blade in a different orientation for use as a shovel. Quick release attachment of the blade to the rear of the snowmobile permits ease of use.

Abstract: A yaw control system capable of detecting a predetermined yaw angle of a towed vehicle and then automatically communicating with a braking system of the towed vehicle includes an actuator and a switch. The actuator and switch operate to detect when a towed vehicle, such as a trailer, has exceeded a predetermined yaw angle. In one embodiment, the yaw control system includes a switch arranged to contact a surface of a plate (i.e., actuator) when the towed vehicle exceeds the predetermined yaw angle. In another embodiment, the yaw control system includes a switch mechanism arranged to contact retractable rods (i.e., actuator) coupled to a hitch assembly when the towed vehicle exceeds the predetermined yaw angle.

Abstract: A fifth wheel hitch lube plate includes a support plate moldably coupled to a cover. By way of example, the support plate is a metallic plate with a number of openings and/or cavities. Some of the openings are configured to receive fasteners while other openings, referred to as cover locking cavities, are configured to cooperate with the cover during the molding operation to mechanically lock or couple the cover to the support plate. The cover locking cavities include an upper, narrow passage that is in communication with a lower, larger cavity. At least a portion of the cover is supported by a top surface of the support plate.
