Abstract: An apparatus to hold and position dumbbells with adjustment through three dimensions (vertical, horizontal and forward and backward) so as to provide an elevated and precisely positioned starting and ending position for the dumbbells used in a dumbbell exercise. The apparatus may be configured as a stand-alone device, an attachment to another piece of equipment (such as a power rack or bench press) or integrated into another piece of exercise equipment such as a lying/incline/seated press apparatus. It enables adjustment of the dumbbell position by the user while the user is positioned for the exercise, as well as prior to assuming the positon for the exercise, to provide precise positioning as desired by each individual user. It features a channeling device which guides a user's hands, wrists and arms when returning the dumbbell to the holder.

Abstract: A versatile ergonomic exercise grip structure with a detachable strap which is applicable to cable attachments, machine attachments, barbells and dumbbells. The ergonomic exercise grip structure is comprised of parallel bars which may be used interchangeably as a grip or support as they evenly share the resistance between them and may engage the body at several points to enable the performance of multiple exercises in a manner that reduces joint strain and improves muscle isolation while being capable providing multiple forms of resistance. The detachable strap enables the performance of multiple exercises with the ergonomic exercise grip structure while serving as a cable attachment by itself. The various embodiments of the ergonomic exercise grip structure enable a trainee to perform multiple exercise in a safe effective manner while using a minimal amount of space.

Abstract: A rotatable handle for a dumbbell bar that allows hand rotation to reduce the risk of shoulder injury. The rotatable handle includes a grip handle part that can be grasped by the user. The rotatable handle also includes an upper side and a lower side that are rotatable with respect to each other. A hard stop mechanism stops the rotation of the upper side so that the grip handle part stops rotating 5-15 degrees from parallel with the dumbbell bar clamped to the lower side. A clamping mechanism is attached to the lower side to secure the bar in place.

Abstract: An exercise device (200) which a user (220) communicates with a base unit (260) whose shape comprises of a first arm projection (340) that ends with a first end (380) located along a radiating line from the base unit (260), and comprises of a second arm projection (440) that ends with a second end (420) ending somewhat away from the base unit (260) in a shape that contacts the user's head, whereby upon the urging of the user of the first end (380) produces at the second end (420) a force onto the user when the second end (420) is at least in contact with the user's head.

Abstract: This device may be used for attaching accommodating resistance devices to a barbell, such as resistance bands or chains. The device is designed to attach to a barbell by sliding it onto the sleeve of a barbell, in the same way that weight plates slide onto the sleeves of the barbell. Once the device is installed on a barbell, the user is able to easily change resistance bands or add/subtract other weights by hanging them from a peg and/or holes in the device. The device may be used for any lift or lifts, but is especially suited to powerlifting movements such as squat, bench press, and deadlift.

Abstract: The present invention recites a scissor arm for an unmanned robotic system such as a UAV, also known as a drone. This arm would typically be installed on the underside of a UAV with hover capability. The arm is designed to simultaneously vertically lower and horizontally extend a payload, permitting a person to interact with the payload without risk of injury by the UAV's propellers. This arm is practical for applications such as a routine police traffic stop, wherein an officer can safely remain in their vehicle and interact with the driver via a drone equipped with communication equipment and such an arm. The drone's arm can present the driver with a box for gathering documents from the driver without risk of injuring the driver or damaging the driver's vehicle. This is accomplished by two inventive “L”-shaped trusses that offset the arm's payload horizontally as the arm is extended downward.

Horizontal bar with apertures will have a resistance element housed within, preferably but not limited to springs; also housed within bar will be spring caps with an protuberance attached that will make contact with Handgrips appendage to engage springs. Handgrips may have indentations to support lower back bar for lower back extension/sit-up assistance exercise. Device may have adjustable resistance.

Abstract: A coupler assembly for selective connection of a surgical instrument to a robotic arm is provided. The coupler assembly includes a stationary hub and a rotation hub. The stationary hub has a first mating feature and is secured to a first one of the surgical instrument and the robotic arm. The rotation hub includes a support member and rotation member mounted on the support member. The support member is secured to a second one of the surgical instrument and the robotic arm. The rotation member is rotatable relative to the support member between a first state and a second state. The rotation member has a second mating feature that releasably couples to the first mating feature of the stationary hub as the rotation member rotates relative to the stationary hub.

Abstract: A tethered ring game and kit is disclosed comprising a tethered ring, means of attaching the tether to an overhead surface, and a novel bottle support apparatus configured and designed to hold and constrain an ordinary bottle in a substantially upright position. The bottle holder apparatus is fixated on a wall, post, or structure such that when a bottle is inserted and constrained, it is used in an eye-hand coordination game of chance involving a tethered ring and a bottle as the target. In practice, a ring, which is tethered and hanging from above in a position equidistant between the player and a bottle, is swung in a pendulum movement toward the bottle, which is constrained by the apparatus, in an endeavor to capture the ring over the top or neck of the bottle.

Abstract: A stationary circular exercise device for exercising via hand and foot platforms, which are removably encompassed in a track and are slideable along the circumference of a circular frame. Resistance to movement can be added with the use of cable or bands that are fixed at one or more locations along the track. Weights can also be attached by the use of pins or pegs, to the cables or bands to increase resistance.

Abstract: A training apparatus and method of use for guiding and improving the forehand, backhand and other strokes of a table tennis player by forcing the hand travel in the correct trajectory to strike the ball. The apparatus includes a waist and a chest belt, or a wide belt, to position a vertical rigid rod support to which the training guide is mounted. The training guide includes a plate that can be adjusted in 6 degrees of freedom via a universal joint. There are two universal joints between the plate and the vertical rod support strapped to the player's torso. The position, orientation and the angle of the plate can be adjusted by the player via the two universal joints as required. The training apparatus improves the paddle stroke trajectory by guiding the hand such that the ball is returned to the opposing player bouncing off the table.

The system includes a head and a jaw assembly, the jaw assembly movably mounted to the head, the head configured for selective engagement with a shoring post, and the jaw assembly configured for engagement with a beam that provides lateral support to the shoring post. The head comprises first and second arms that extend in the same general direction and when engaging the shoring post the first and second arms are disposed upon opposite sides of the shoring post. The jaw assembly includes a fixed jaw and a movable jaw, the moving member pivotably connected to the fixed jaw, wherein the fixed jaw and movable jaws are configured to receive an end of the beam therebetween.

Abstract: A wind-diverting panel centrally located under the body of a vehicle inhibits air from otherwise being displaced laterally inward by the passing wheels of the moving vehicle. Maintaining air to remain generally static while passing under the vehicle through the central open-space between the wheels increases the effective air pressure developed immediately behind the vehicle to reduce overall drag between the front and rear of the vehicle.
