Abstract: An adjustable structure is described herein according to various embodiments, including an inner tube member and an outer tube member. The inner tube member and the outer tube member are configured to move in at least one of a telescoping direction or a rotation direction with respect to one another. The adjustable structure further includes a first frictional element between the inner tube member and the outer tube member. The first frictional element provides friction in the telescoping direction. Furthermore, the adjustable structure includes a second frictional element between the inner tube member and the outer tube member. The second frictional element provides friction in the rotational direction.

Abstract: A roller skate device, including: at least one skate wheel. A cradle including a control wire. And a lever system coupled to the control wire, the lever system including at least one brake wheel that applies a braking force to the at least one skate wheel based on the motion of the cradle translated through the control wire.

Abstract: An independent friction joint structure including: at least one plug part having a connection to a device, the device comprising a lamp head; at least one joint part holding the at least one plug part in place, the at least one joint part having at least one holding structure; at least one side part having the ability to generate frictional rotational resistance to keep the at least one plug part in a predetermined position; at least one electrical contact between the at least one side part and the at least one holding structure of the at least one joint part; and at least one screw to fit all the components of the independent friction joint structure together.

Abstract: A mechanism for the conversion of a force applied in one direction to a rotational force. The rotational force may provide for movement in a second direction. The system utilizes mechanical parts and the movement of these parts to convert the directional force to a rotational force. The system can help to utilize unused forces to the benefit of a user reducing workload and/or increasing speed.

Abstract: A shutter assembly for a receptacle including a plate, a card disposed adjacent the plate, a shutter disposed between the plate and the card, a first biasing member for providing lateral movement of the shutter, the first biasing member abutting a first extension of the plate; a second biasing member for providing transverse movement of the shutter, the second biasing member for providing a first pivot point to the shutter; and one or more protrusions for providing a second and/or third pivot point to the shutter, the protrusions disposed between the plate and the shutter. In one example the receptacle may be an AC outlet.
