Abstract: The invention includes a display positioning assembly comprising a support, a display supported by the support, and a balance mechanism carried by the display and operatively connected to the support. The invention also includes an article for selectively exposing a display comprising a generally planar support surface having a first side and a second side opposite the first side. A balance mechanism operatively connected to a display may be positionable between a storage position proximate the first side of the generally planar support surface and an exposed position proximate the second side of the generally planar support surface. The invention also includes an assembly for arresting the free fall of an object. The assembly may comprise an outer slide in sliding or rolling engagement with an inner slide, and a brake comprising at least one pivot member may be coupled to the inner slide.

Abstract: A mounting system is provided. The mounting system is adapted for mounting a device such as a video display on a surface such as a wall for example. Mounting system configurations include a tray to help align a mating feature with a keyhole opening. Other configurations include a retaining device to hold a mating feature within the mounting system for added security. Other configurations include a locking device to prohibit unwanted motion of the retaining device and theft protection.

Abstract: A system for providing support and position control of a monitor. In one embodiment, a method of supporting a monitor includes converting an ascending energy storage member force curve into a substantially constant supporting force against the monitor. In one aspect, a method, of supporting a monitor includes providing an energy storage member and a cam which are cooperatively positioned so as to move relative to each other along the path of motion. As the energy storage member moves along the path relative to the cam, the cam displaces the energy storage member and thereby changes a force applied by the energy storage member on the cam, and wherein the cam converts the force applied by the energy storage member into a supporting force on the monitor.

Abstract: Methods and apparatus for providing an adjustable balancing force are provided. This mechanism can be used as a lifting force, a counter balancing mechanism or as a horizontal or other force mechanism. The force can be designed to be constant or variable over the range of motion by properly calculating the shape of the cam member. A balancing mechanism in accordance with the present invention includes a wheel comprising a pulley member and a cam member. A first cable connects the cam member of the wheel to a energy source for biasing the wheel to rotate in a first direction. A second cable is connected to the pulley member of the wheel for communicating a balancing or load force to the wheel. In some useful embodiments of the present invention, the cam member is shaped and positioned so that a torque applied to the wheel by the first cable is substantially constant while a force applied to the wheel by the first cable varies.
