  • Patent number: 7137603
    Abstract: A desktop electronic device translates on a desktop from a first position to a second position through use of at least one mobility assembly. The mobility assembly(s) may be integral with the desktop electronic device, connected to the desktop electronic device, or integral with a platform that supports the desktop electronic device. The mobility assembly(s) include at least one primary revolving element and optionally includes at least one secondary revolving element in contact therewith. The primary and secondary revolving elements may be spherically or cylindrically shaped in any combination. A spherical primary revolving element allows the desktop electronic device to translate linearly or non-linearly. Brakes or disengaging mechanisms may be combined with the desktop electronic device, mobility assembly(s), or platform to resist or prevent movement of the desktop electronic device.

  • Patent number: 7092251
    Abstract: A chassis for receiving a plurality of disk drives includes a plurality of disk drive receiving stations. Each station is configured to carry out testing and/or servo writing operations on a received disk drive. Each station includes a base, a nest assembly and a plurality of elastomeric mounts that elastically couple the nest assembly to the base to enable movement of the nest assembly relative to the base. The nest assembly includes a nest configured to receive and mate with the disk drive and a printed circuit board. Each station includes a separate vibration isolating mass that is coupled to the nest. The vibration isolating mass at least partially isolates vibrations originating within the nest from being transmitted through the elastomeric mounts to other nests in the chassis and at least partially isolates vibrations originating outside the nest from being transmitted through the elastomeric mounts to the nest assembly.

  • Patent number: 6719258
    Abstract: A seat assembly for a motor vehicle includes an air spring suspension system for effectively isolating the occupant of the vehicle's seat from shock, vibration and inertial forces directed along both a vertical axis and a horizontal axis. A stationary base plate member is attached to the floor of the vehicle and it supports a pivot linkage assembly joining the stationary base member to a movable base member. An air spring is disposed between the stationary base member and the movable base member to displace the movable base member in a generally vertical direction to an extent allowed by the linkage assembly. Supported atop the movable base member is a seat slide assembly that permits fore and aft adjustment of seat position within the vehicle. A vehicle seat mount is affixed to the pair of slide members and includes shock absorbing springs that are disposed between the slide members and the vehicle seat mount for cushioning inertial forces due to acceleration and braking.

One of the four-bar linkages is secured to a stationary "ground" structure, and the other linkage is attached to the object to be supported, such as a mirror. In one embodiment, two links of each of the two four-bar linkages are constructed from spring steel flexure elements which are rigid in all directions except about the rotational axis. The flexure elements thus comprise "revolute joints". Because the flexure elements function as spring hinges, no friction is encountered when the suspension is displaced or "pivoted".

  • Patent number: 5429338
    Abstract: An equipment mount for isolating equipment from shock loads and acoustic vibrations has a ring-shaped base mounted to a foundation. A generally cylindrical retainer has an X-shaped cross section and a pair of contact surfaces forming the X-shaped cross section and disposed at an angle relative to the axis of the retainer. The retainer is movable relative to the base. A generally cylindrical resilient member is disposed between the base and the retainer. The resilient member includes a kick segment at either end thereof projecting outwardly at an angle relative to the axis of the resilient member and having an end contacting one of the retainer contact surfaces when free standing. The resilient member is deformable under load so that a greater portion of at least one of the kick segments contacts at least one of the retainer contact surfaces to isolate the equipment from the load.

  • Patent number: 5275371
    Abstract: A springy, low dielectric retainer device in the form of a rod, a triangle, an ellipse or whatever, is used in a compressed condition to hold RF energy absorber blocks in position juxtaposed "energy leaky" RF circuitry. The absorber blocks are held in position due to frictional forces provided by the compressed retainer. In this manner, the absorber blocks can be re-positioned to obtain optimum amplitude/frequency response characteristics from the affected RF circuit.

  • Patent number: 5249417
    Abstract: A method and apparatus to install and remove heavy components mounted on a base structure is disclosed. Various construction details are developed which provide means for coupling the component and base structure in a manner permitting relative rotation and translation about an axis of rotation. In one embodiment, an aircraft engine component (18) has a pair of hooks (32) and an aircraft engine (10) has a pair of pins (46) which engage the hooks to couple the component and engine to permit rotational and translational motion of the component relative to the engine. For this embodiment, a method for relative motion between an installed and uninstalled condition is comprised of maneuvering the component and engine between a coupled and uncoupled position, moving the coupled component relative to the engine about the axis of rotation, and manipulating a fastener means between a secured and unsecured position.

  • Patent number: 5042396
    Abstract: A plastic pallet in which an insert assembly is positioned within the hollow of the plastic pallet to discourage warpage and failure especially in racked, storage situations. The insert assembly comprises a pair of beams arranged in an X-configuration, tower members secured at their upper ends to respective ends of the beams and positioned respectively in the four corners of the pallet, and tensioning straps extending between the tower members around the perimeter of the pallet proximate the upper surface of the bottom wall of the pallet. The X-configured beams are positioned in the space between the spaced upper and lower sheets of the platform structure of the pallet and are maintained in a convexly bowed configuration by the tensioning straps so as to resist downward bowing of the platform structure, even when the pallet is racked for extended periods of time in a loaded condition.

  • Patent number: 5037060
    Abstract: The present invention relates to a load distribution composite. This comprises a plurality of lower wedges with their broader bases disposed in a slideable spaced-apart relation along a resting plane.
