A mechanical arm assembly which has two arm members connected by an elbow. The movable connectors at the end of each arm are connected by belts or the like to a locking mechanism at the elbow such that engaging the locking mechanism simultaneously locks both movable connectors as well as the elbow.

An assembly includes an attachment arm having an axle extending from a first end of the attachment arm. The attachment arm of the detachable wheel assembly further includes a securing portion forming a second end of the attachment arm, the securing portion of the attachment arm including a pin positioned to extend above a first frame member of a gantry truss and to secure the first frame member between the pin and a portion of the attachment arm. The attachment arm also includes a frame support corresponding to a second frame member of the gantry truss such that the frame support supports the second frame member when the assembly is secured to the gantry truss, and the assembly includes a wheel rotatably attached to the axle of the attachment arm.

Disclosed is a display device. The display device of the present disclosure includes: a rail which extends long; a moving wall which extends long in a direction intersecting the rail and has a display panel; and a rod which is positioned between the rail and the moving wall; wherein one end of the rod is coupled to the rail to be movable in a length direction of the rail, and the other end of the rod is fixed to the moving wall, wherein the moving wall is movable in the length direction of the rail.

A method controlling a vehicle moving along a guideway for magnetic flight is provided. The method includes receiving, at a controller, data generated by one or more sensors. The controller receives data relating to a projected flight path of the vehicle. The controller determines an altitude of the vehicle relative to the guideway for magnetic flight and determines a speed of the vehicle relative to the guideway for magnetic flight. The controller then calculates a deviation of the vehicle from the projected flight path. The controller adjusts the altitude of the vehicle relative to the guideway for magnetic flight by changing certain aspects of a magnetic flight suspension system causing the vehicle to more closely track the projected flight path.

A security apparatus for a launch monitor comprises a guide member extending from a first end to a second end. The guide member comprises a top surface defining one or more top surface features, and opposing side surfaces defining one or more side surface features. A mount is configured to moveably couple to the guide member. The mount comprises a mount body, and a plurality of securing members. Each of the securing members includes a retainer configured to retain and secure a portion of the launch monitor to the mount body and enable the launch monitor to be moved relative to the guide member.

A rail element (10, 33) for a camera slider system or, more generally, a tube joiner for a rail comprised of an expansion device (23, 30), located internally at an open end (12, 32) of a tubular body (11, 33). The expansion device is configured to fit within a male part or joiner element (16, 31) that may be inserted into the end of the tube (10, 33) and can be actuated to an expanded state where it exerts force radially outwards through the joiner (16, 31) to hold it against the open end (12, 32), thereby joining two tubular or rail element ends together.

A refrigerator including a display module that is movable upward and downward and rotatable. The refrigerator includes a main body forming a storage compartment, a door configured to open and close the storage compartment, a display module coupled to the door, and a sliding plate disposed between the door and display module and coupled to be slidable in upper side and lower side directions with respect to the door and configured to allow the display module to be rotatably coupled thereto. The display module is provided to, when the sliding plate slides in the upper side and lower side directions, slide in the upper side and lower side directions with respect to the door together with the sliding plate, and rotate with respect to the door as the display module rotates with respect to the sliding plate.

An aerial movement system and method for calibrating same includes, generally, registration points and wireless position transceivers proximate the registration points and the object that communicate with a computer and allow for the computer to determine the appropriate amount of support lines to draw in or release.

A kit of portable modular components for use in demountably configuring a variety of structural assemblies. The kit comprises three types of elongate structural support components wherein the first type has a pair of opposed male ends, the second type has a male end and an opposed female end, and the third type has a pair of opposed female ends, wherein the male ends are configured for demountable engagement with the female ends. Each of the male ends comprises a cylindrical body with at least one linear set of two spaced-apart prongs around the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels for receiving therein the cylindrical body and the at least one linear set of prongs. The female ends are provided with locking assemblies for releasable engagement the male ends.
