Abstract: A cellular modem may give notice of changes in modes. The modem will change modes as a result of the breaking of a trip wire or the closing of contacts that are normally open or the opening of contacts that are normally closed or sensing motion or light, or sensing variations in resistance. One contact is provided to wake the unit from “sleep” and the other is provided to detect intrusion, motion, etc. Light detectors can detect light, such as when a closed container is opened. Closed contacts can be used in parallel to change any mode or open/closed contacts in parallel/series. The modem can be used to apprehend people breaking into or stealing luggage, equipment, boxes, etc. The present invention informs the user when the object being monitored is being moved or opened and can track the object's location.

Abstract: A turbine airfoil having an improved impact and erosion resistance. The airfoil comprises: (a) a base segment having an impact resistant leading edge section proximate to the leading edge comprising a material having having a yield strength of least about 250 ksi and an elongation percentage of about 12% or less; and (b) an erosion resistant coating overlaying the base segment at least in the leading and trailing edge portions of the pressure side, the erosion resistant coating comprising at least one ceramic layer having at least one of the following properties: (1) an erosion value of at least about 200 g. of erodent to cause a thickness loss of about 15-20 microns; (2) an erosion volume loss value (V) of about 1.9 or less as defined by the equation V=H?0.18×E0.75×F?1.65 where H is hardness, E is elastic modulus and F is fracture toughness; and (3) an F value of at least about 1.5 MPa*m1/2.

Abstract: A rod end bearing comprising a body comprising a ring portion and a rod portion. The ring portion comprises a ring having an opening, the opening having a center axis. The rod portion comprises a first rod extending radially from the ring in a direction perpendicular to the center axis. The opening having a geometry sufficient to support a substantially spherical ball bearing, and permit rotation of the ball bearing inside the ring. The inner periphery of the ring is in contact with the ball bearing and includes a wear coating. An antifriction coating is disposed on a surface selected from the group consisting of a surface of the wear coating, a surface of the ball bearing and combinations thereof. The antifriction coating maintains a coefficient of friction between the wear coating and the ball bearing of up to about 0.95 in atmospheres substantially devoid of water vapor.

Abstract: A gas turbine engine component having opposed surfaces in frictional contact with each other. An antifriction coating is disposed on one or more of the opposed surfaces. The antifriction coating includes a binder and a friction modifier. The weight ratio of the friction modifier to binder in the antifriction coating is greater than or equal to about 1:1.

Abstract: A variable gas turbine compressor vane assembly comprising a case structure comprising a cavity. A compressor vane is at least partially disposed inside the cavity in the case structure. The portion of the compressor vane is rotatably supported inside the cavity. A wear coating is disposed on at least a portion of a surface of the compressor vane. An antifriction coating is disposed on the wear coating. A bushing is disposed between the antifriction coating and the case structure. The bushing is in sliding contact with each of the antifriction coating and the case structure. The antifriction coating maintains a coefficient of friction between the antifriction coating and the bushing of equal to or less than about 0.95 in atmospheres substantially devoid of water vapor.

Abstract: An animal control apparatus (10) with a collar based receiver (20) wirelessly linked to a stimulator (110) attached to the animal's ear. In a preferred embodiment, the receiver broadly comprises a GPS component (30); a wireless transmitter (40); a receiver processor (50); a power supply 60; and an attachment mechanism (80). The stimulator (110) broadly comprises a wireless receiver (120); a stimulation circuit (130); a stimulator processor (150); a stimulator power supply 160; and a stimulator attachment mechanism (180). The apparatus (10) is adapted to monitor an animal's location and deliver a corrective stimulus to the animal if the animal enters a restricted location.

Abstract: A motion detector includes a plurality of electrically conductive spheres contained within a chamber having a height slightly greater than the sphere diameter. In a first embodiment, a top wall of the chamber consists of a circuit board having a pattern of conductive metal installed thereon including one pattern for one conductor and another pattern for another conductor with the two patterns being interrelated so that spheres rolling within the chamber can make and break electrical circuits. In a second embodiment, both the top and bottom walls of the chamber consist of circuit boards having patterns of conductive metal thereon. In either embodiment, the pattern of conductive metal may be spiral-shaped, either circular or elliptical, concentric circles or concentric ellipses, an array of dots or an array of rectangles.
