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.

Methods and apparatus for generating force and torque

A coordinate positioning machine comprises a fixed structure including a table and a supporting frame (314), rigidly connected together. A moveable arm (310) is suspended from the frame by means of three powered telescopic struts (316), each of which is universally pivotally connected to both the arm and the frame. As a consequence the moveable arm is able to move with three rotational degrees of freedom. Movement of the arm with each of these degrees of freedom is constrained by a passive device (340), connected to the arm and the fixed structure, and which eliminates all rotational movement of the arm, while simultaneously permitting translation thereof.

Coordinate positioning machine

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.

Lift mechanism systems and methods

A force adjustment assembly for use within a telescoping subassembly that includes a first elongated member and a second elongated member that is supported by the first elongated member for sliding motion along an extension axis, the subassembly further including a force equalizer assembly that includes a strand having first and second ends that are supported by the second and first elongated members, respectively, the adjustment assembly comprising a preloader supported by at least one of the first and second elongated members and supporting at least a portion of the strand, the preloader applying a preload force via the strand when the second elongated member is in a fully extended position and an adjuster for adjusting the preload force applied by the preloader.

Load compensator for height adjustable table

A projector that can project a picture up and down on a screen free
from the trapezium deformation, and allows the projection lens to be
exchanged with other projection lens by an easy operation from outside of the
front panel, without necessitating dismounting of any of the internal
structure of projection apparatus. Projection lens shifts its standing up and
down in accordance with revolving of a revolving knob disposed on the upper
part of the projection apparatus. For the exchange of projection lens, a
projection lens can be unscrewed and detached from the outer cylindrical
section 9-2 of lens holding member 9 by turning the inner barrel 8 from
outside the cabinet at the front.

A coordinate-measuring instrument has a purely mechanical device (14) to compensate for the weight of a vertically displaceable spindle (9). The compensation device consists of a helical-coil spring having a working range which is small as compared with its length in relaxed condition, and a belt transmission interposed between the spring and the spindle (9). The belt transmission is preferably developed in the manner of a block and tackle. A first or drive pulley engages and drives the belt for Z-axis positioning of the spindle, and a second or belt-tension pulley applies weight-compensating tension to the belt.

Interchangeable lens retaining means for photographic cameras, so designed that the interchangeable lens may be placed on or removed from the camera by a simple axial movement in the direction of the optical axis, without requiring the rotational or twisting movement required when a conventional bayonet type mount is used. Shoulders on the interchangeable lens are engaged by a plurality of pivoted latches on the camera, the parts being beveled so that the latches are automatically thrust aside as the interchangeable lens is brought toward its seated position on the camera, and then snap behind the retaining shoulders on the lens. The latches are coupled to each other so that all move in unison. A radially movable button on the lens operates a lever to disengage all of the latches on the camera, so that the lens may be removed axially from the camera.

Interchangeable lens retaining means for photographic cameras

A control device independent of and designed for use with professional cameras for operating an electromagnetically drivable shutter or magnetic shutter and for determining and setting exposure values, wherein the device includes a power source and means for determining and setting exposure values, both of which are exchangeably or detachably connectable operatively via the control device to the magnetic shutter and to a light measuring or metering probe, the means for determining and setting the exposure values being adjustable to operate in a plurality of selective functional modes.
