Abstract: A user information user interface for a networked software service is provided. The user information user interface corresponds to a request for information and is generated to overlap the software service user interface. The user information user interface includes a pointer to a display control on the software service user interface and data corresponding to the display control. The user information user interface can also include a set of selectable icons to facilitate selection of different display controls.

Abstract: A rotational vibration testing device, including a rotating table, for testing both rotary shock and rotary vibration when used in conjunction with a pivoting shaker. The rotating table is mounted on a hub rotationally supported between two compression rings via tapered annular roller bearings preloaded in opposition. A motion arm connects to a radial arm on the side of the hub. The other end of the motion arm mounts to a height adjuster, which bolts to an electrodynamic shaker or other force generator. When the motion arm moves fore and aft, the linear acceleration is converted to rotational acceleration based on the radius from the stinger to the center of rotation. A nylon or equivalent median between the motion arm and the hub allows for sufficient flex without fore and aft play. The large tapered roller bearings preloaded in opposition eliminate z-axis acceleration and allow for greater payload testing.

Abstract: A rotary shock testing system including a rotating table mounted to a bearing plate of a precision bearing assembly. The bearing plate to which the rotating table is attached preferably includes upper and lower surfaces supported against ported plates to thereby prevent vertical translation of the bearing plate along the axis of rotation. Oil is injected through ports in the ported plates to provide a substantially frictionless hydrostatic bearing between the upper and lower surfaces of the bearing plate and respective surfaces of the ported plates. The precision bearing further includes a pair of tapered bearings and a roller bearing, spaced along the axis of rotation, which bearings further support the bearing plate for substantially frictionless rotation while preventing translation in a direction perpendicular to the axis of rotation and precession of the axis of rotation. The tapered bearings further assist in preventing vertical translation of the bearing plate along the axis of rotation.
