Abstract: A dental model gripping system can include a dental model and a dental model gripper. The dental model can include a replica set of teeth and a flat bottom surface there beneath that can include first and second vertical openings spaced apart by an opening distance. The dental model gripper can have a flat top surface and first and second pins extending vertically therethrough that can slide toward and away from each other. The first and second pins can be slid to an engaging position where they are spaced apart by the opening distance and are insertable into the vertical openings of the dental model, can be slid away from each other to a gripping position while inserted into the vertical openings, and can press against internal surfaces within the vertical openings to grip firmly the bottom surface of the dental model against the top surface of the dental model gripper.

Abstract: An attachment is intended to be affixed to a vehicle's ladder rack to improve the air drag of both the ladder rack and load attached thereto. The location of the attachment allows it to perform the intended function of creating an adjusted wind flow which would otherwise hit both the ladder rack and the load directly causing a drag force. The drag force results in increased fuel consumption. The attachment therefore increases the safety of the attached load, vehicle, and driver, as the load and vehicle are not jostled around by drag force caused by the wind flow.

Abstract: An automatic carriage return for an exhaust removal system having a carriage that is configured to translate along a track tube. The automatic carriage return includes a drive cable spanning along the track tube, and an engagement assembly coupled to the carriage. A drive motor drives motion of the carriage along the drive cable when the engagement assembly is in the engaged configuration. In the disengaged configuration, the engagement assembly is configured to be disengaged from the drive cable to allow the carriage to freely follow the path of the vehicle. Upon release of the extraction hose from the vehicle, the engagement assembly is configured to automatically activate to the engaged configuration to engage the drive cable.

Abstract: An automatic carriage return for an exhaust removal system having a carriage that is configured to translate along a track tube, the carriage being coupled at a first end to an exhaust extraction hose, the second end of the exhaust extraction hose being coupled to a vehicle exhaust for directing exhaust from the vehicle out the track tube. The automatic carriage return includes a drive cable spanning along the track tube, and an engagement assembly coupled to the carriage. The engagement assembly has an engaged configuration and a non-engaged configuration with respect to the drive cable. A drive motor is coupled to the engagement assembly, and drives motion of the carriage along the drive cable when the engagement assembly is in the engaged configuration. In the disengaged configuration, the engagement assembly is configured to be disengaged from the drive cable while the exhaust extraction hose is attached to the exhaust of a vehicle to allow the carriage to freely follow the path of the vehicle.
