Abstract: The present technology generally provides swing gate actuator assemblies. In particular, some embodiments of the present technology provide a fastener configured to secure an arm of the actuator assembly to a swing gate panel. The fastener can be configured to permit a longitudinal axis of the arm to pivot about a pivot portion on the fastener, thereby reducing the likelihood of gate malfunction in response to a misalignment event.

Abstract: A dual arm barrier assembly comprising spaced-apart stanchions and a pair of barrier arms pivotally connected to a first stanchion for movement between closed and open positions. The barrier arms have distal end portions immediately adjacent to and out of engagement with the second stanchion when in the closed position during normal operation and when the vehicle is out of engagement with the barrier arms. The first barrier arm in the closed position is at a height corresponding to vehicle's windshield, and the second barrier arm in the closed position is below the first barrier arm and is at a height corresponding approximately to the vehicle's body or frame. The second stanchion engages the barrier arms only when the vehicle presses against barrier arms, thereby securely retaining the barrier arms in the closed position.

Abstract: A linear gate drive assembly with a drive rail connectable to a gate panel. The drive rail has a first drive surface. A linear drive portion is coupled to the first drive surface and has teeth thereon with a first rolling tooth profile. The linear drive portion defines a toothed second drive surface. Dive motors are pivotally coupled to a support structure. A first drive wheel is attached to one drive motor and engages the first drive surface to impart an axial drive force on the drive rail. A second drive wheel is attached to another drive motor and engages the second drive surface. The second drive wheel has second teeth that mate with the first teeth and that define a second rolling tooth profile that substantially corresponds to the first rolling tooth profile. Rotation of the second drive wheel imparts axial and normal forces via a rolling teeth interface the mating teeth for moving the drive rail and the gate panel.

Abstract: The present disclosure relates generally to barrier assemblies, and more particularly, to the coupling of a barrier operator to the barrier that the operator is to move. In one embodiment, a barrier operator coupling includes a wedge member that is fixedly attached to an output shaft of the barrier operator. A housing is brought to bear against a wedge member, and an adjustment device is used to maintain the force between the wedge member and the housing.

Abstract: An exercise apparatus having a pair of support pedals that, when a user steps upon both pedals, can be moved by the user in a closed path that is designed to be complimentary in motion to that of the user's natural stride. The pedals are operably connected by a linkage that facilitates this natural motion. Moreover, this linkage can be adjusted thereby altering the shape of the closed path traveled by the pedals. The closed path can thus be altered to conform to the optimal biomechanics of each individual user or, it can be altered to form a closed path designed for more of a striding type of exercise or for more of a climbing exercise, thereby allowing different muscle groups to be exercised on the same machine.
