A magnetic composition comprising nanocomposite particles comprising from about 0.001 to about 60 weight percent of magnetic nanocrystalline particles dispersed in from about 40 to about 99.999 weight percent of a discrete phase matrix, and a continuous phase matrix, wherein the discrete phase resides in interstices within the continuous phase matrix.

An Improvement to enhance the usability of magnetic compasses by eliminating acceleration and turning errors, especially in aviation applications, without compromising simplicity and reliability. The improvement includes the addition of a weightless mass to the bar magnet of a conventional magnetic compass to counteract undesirable inertial forces on the bar magnet.

A satellite dish antenna targeting device which corrects for incline and parabolic offset angle. The satellite dish antenna is connected to a base by a support member so that the satellite dish antenna is able to move through an elevation. An inclinometer is mounted to move in unison with the satellite dish antenna for sensing when the base is oriented at an inclination angle with respect to a tangent to the earth at a location where the satellite dish antenna is being targeted. The inclinometer further senses the elevation the satellite dish antenna moves through. The inclinometer thereby provides a dish elevation corrected for the incline and elevation of the satellite dish antenna to a microprocessor. The microprocessor corrects the dish elevation for the parabolic offset angle of the satellite dish antenna. A display device connected to the microprocessor displays a corrected dish elevation of the satellite dish antenna. The satellite dish antenna is thus rapidly and accurately positioned within one degree to receive the satellite signal by moving the satellite dish antenna until the display device displays a predetermined target elevation compensated for by the incline and/or parabolic offset angle of the satellite dish antenna.

An apparatus and method for sensing angular displacement of a rotating object. A reference object is provided that maintains an independent angular reference. An angular displacement of the rotating object may be measured with respect to the reference object. The apparatus may include a turn sensor for measuring directional changes in the heading of the object, an angular compensator, and a servomotor for maintaining the turn sensor in a same angular position. The object may be a vehicle such as a boat, car, train, airplane or any other vehicle. The turn sensor is coupled to the servomotor that may be attached to a platform of the vehicle. As the vehicle rotates, the heading of the vehicle changes. The servomotor rotates the turn sensor housing to keep the sensor at the same angular position. The heading may be determined by measuring an angular difference between the position of the turn sensor in relation to the moving object.

An angle measuring guide includes a housing having a plurality of monolithically formed walls and an annular opening formed within selected ones of the walls. The rear wall has a planar surface for being directly mated with the motorcycle. A transparent lens is monolithically formed with the housing and directly connected thereto. A buoyant member is situated within the opening and the cavity. A predetermined quantity of high viscous fluid is contained within the opening and the cavity such that the fluid freely flows therebetween and supports the buoyant member at a free and suspended position during operating conditions. The buoyant member includes a stationary weight member connected to a bottom portion thereof and thereby anchors the buoyant member while allowing the buoyant member to freely rotate about one or both of the x-axis and y-axis.
