Abstract: In accordance with the present invention, there is provided a workstation or other heavy object which is easily moved, yet steady and stable when parked. Underneath this object is attached a multiple air-bearing device having a backplate, a membrane which is selectively bonded to the backplate, and a stencil and dimple which further prevent separation of the membrane from the backplate and which also provide a bearing surface for the workstation to rest with stability against the floor. Pressurized air is introduced through the base and behind the unbonded portions of the membrane, inflating the membrane and creating lift, and additionally forming a pneumatic seal against the floor. Air passages through the membrane and within the sealed footprint allow air to flow into and through the region between the membrane and the floor, creating an air-lubricated bearing that allows nearly frictionless motion of the heavy object.

Abstract: An improved probe includes a conductive tubular housing or body containing a coil spring and a conductive plunger movable in the housing and having a contact tip outwardly extending from one end of the housing. The plunger and tip are urged to a normally outward position by the bias force of the spring. The opposite end of the housing has an opening for mating with a conductive pin of a connector. The connector is retained in a mounting plate of an associated fixture and has terminal ends of desired configuration. The terminal end may include a wire-wrap pin, a crimp type terminal or wire jack for attachment to a wire, or the terminal may include a spring loaded pin for engagement with an associated electrical contact. An air tight seal may be provided between the probe and the connector and the connector may be mounted in a mounting such that when vacuum is applied to an associated test fixture, air cannot be drawn through the fixture or through the body of the probe.
