Abstract: A system for qualifying and monitoring bearing performance and condition in a rotary servo system. A position error signal is analyzed for signal anomalies that can signify bearing damage. A DC offset ramp is applied to the position error signal to test whether the anomaly is angular position dependent. The anomaly is associated with the corresponding command signal value and range of values to calculate the angular position and range of the apparent bearing damage. The amplitude of the anomaly is measured and associated with a relative degree of bearing damage.

The cup can include a body member having an inside surface and an outside surface, and a bottom panel member having a upper surface and a bottom surface. The body member is coated (or in some instances partially coated) on its outside surface with a foamed low density polyethylene, and on its inside surface with an unfoamed modified low density polyethylene. The bottom panel member is coated on its upper surface with a foamed or an unfoamed low density polyethylene or foamed or unfoamed modified low density polyethylene. The body member and bottom panel member are oriented and joined to form a heat seal at an interface between a portion of the unfoamed modified low density polyethylene coated on the inside surface of the body member and a portion of unfoamed low density polyethylene or unfoamed modified low density polyethylene coated on the upper surface of the bottom panel member.

Abstract: A rotary bearing includes concentric radially spaced-apart inner, intermediate and outer rings whose opposing surfaces define inner and outer ball tracks. An inner array of balls roll along the inner track and an outer array of balls roll along the outer track and a viscous lubricant is present between the rings. When the inner and outer rings are angularly reciprocated relative to one another and that reciprocation is changed, the intermediate ring is moved intermittently in a selected direction about the rotation axis so that the balls recirculate about the axis and redistribute lubricant along the tracks.

Abstract: A method of manufacturing a two-section flag pole comprising a pointed lower section for planting into the ground and an upper section having a colored area and a numbered flag for establishing a target in a game of flying-disc golf. Each flag may be removed from or rolled over the pole and the pole can be disassembled for ease of storage. A threaded or snap-on quick-coupler is used to assemble the two sections of each pole, so that it may be easily and quickly installed at each selected target site.

Abstract: The present invention features a slab laser apparatus having a stable/unstable resonator. The slab laser comprises a slab-shaped medium for producing a beam of coherent light. The slab-shaped medium is physically defined by an entrance end face; a rear, exiting end face; and two oppositely disposed and substantially parallel side faces. The respective end faces of the medium are disposed along an axis defining a "p" plane; the side faces are disposed along an axis defining an plane. A light beam entering at the entrance end face of the slab-shaped medium along the "p" plane axis reflects back and forth within the slab-shaped medium via total internal reflection, exiting at the rear end face. A stable optical cavity is defined for the "p" plane, comprising a hemispherical, high reflector curvature having an finite radius of curvature, and a flat, partially reflecting, outcoupler. An unstable optical resonator is defined for the plane, which operates in a low order transverse mode. The resonator in the plane consists of a high reflector mirror, and a negative radius of curvature, partially reflective mirror. The partially-reflecting outcoupler is a substantially cylindrical optical component onto which has been coated a variable reflectivity mirror (VRM) profile. The transmission of this mirror surface varies in the transverse direction. The optical component is flat in the "p" plane and cylindrical in the "s" plane. The VRM coating is disposed on the cylindrical face. The outside surface may be coated with an anti-reflective coating.

Abstract: An interferometer bearing assembly including a fixed glass rail, a movable carriage that carries both the movable interferometer mirror and the drive coil for the linear motor, and a mechanism for biasing the carriage onto the rail. The glass rail has two optically flat faces defining a normally horizontal line of intersection. The carriage is a rigid structure with plastic surface portions that provide a bearing interface for contacting the flat faces of the glass rail. To improve stability and reduce the possibility of any transverse movement, the carriage is downward biased, preferably by providing an overlying glass plate with a downwardly-facing flat surface, and mounting a spring-loaded plastic element to the top of the carriage. The plastic element contacts (and slides along) the flat glass surface and transmits a downward force to the carriage.

Abstract: A system for determining range and orientation of distant objects such as a ship. By utilizing split imaging the observed height on a video monitor can be accurately determined despite movements of the image on the monitor. The observed ship can be visually identified and the true height determined from reference sources. A better comparison of data indicating the true height compared to observed height permits calculation of the range to the target ship. Split imaging can also be utilized to determine the observed length of the ship so that observed height and length data can be compared to the true height and length of the target ship to determine orientation of the target ship relative to the observer.
