Abstract: A tool with three tools combined in one to produce a more time consuming, efficient, and quality in leveling and squaring corners, frames, door jambs, window frames, laying bricks and masondry with cement floors or side walks. The Easy View Level Square has three unique features. One is the ability of each one of three viewing chambers to pop up perpendicular to the body of the level bar for a visual of the level bubble from any angle or short distance. The second feature is that the Easy View Level Square has a tongue blade that can open from it's trough or the body of the level bar to create a framing square useful in checking the square of corners and perpendicular structures. And the third unique feature is a ruler used for quick marks and measurements at short distances or uneven spots while checking for level to mark it.

Abstract: A triangle ruler includes a triangle ruler body defining three corners, three sides, opposing first surface and second surface surrounded by the three sides and three corners and a recessed annular scale located at the center thereof, and a direction indicator including a pendulum and a pointer and pivoting about the center of the recessed annular scale in such a manner that the pivot axis of the direction indicator extends perpendicular to the first and second surfaces of the triangle ruler body, and the effects of the weight of the direction indicator keeps one end of the pointer to constantly indicate a predetermined direction. Thus, the invention combines the functions of a conventional protractor and a conventional triangle ruler to facilitate drawing a variety of different angles of lines.

Abstract: A method and system are presented for use in determination of the orientation of an aerospace platform with respect to a first rotation axis. A direction of a rotation rate vector of said aerospace platform within a lateral plane intersecting with said first rotation axis is measured and the measured data is analyzed to determine an orientation angle of said aerospace platform about said first rotation axis. While the aerospace platform is in a predetermined-dynamic state movement, a certain direction is determined by measuring a direction of the rotation rate of the aerospace platform within said lateral plane by a sensor assembly mounted on said platform and including at least one rotation rate sensor. An orientation of the platform with respect to said first axis is determined by determining a relation between said certain direction and said known direction within said external reference frame.

The second sensor die is positioned such that the second active sensor circuit is oriented orthogonally with respect to the first active sensor circuit region and is perpendicular to the base. The second surface is adjacent to the first surface and angled with respect to a plane of the first surface.

Abstract: The steering wheel adapter for a motor vehicle has, for connection to a steering wheel, a rotatable retaining plate (10) with at least three retaining elements (11, 12, 13) that are displaceable within a circular segment formed by the upper region of the steering wheel (50) and whereby the steering wheel (50) is frictionally connectable to said retaining plate (10). This upper circular segment is used as a free space for coupling the steering adapter to the steering wheel, with all retaining elements that serve to clamp the steering wheel to said retaining plate being disposed within this free space so that their retaining force is generated against the steering wheel from the inside. In the steering wheel plane outside the steering wheel rim, no components are therefore required that could come into conflict with other components of the motor vehicle in the vicinity of the steering wheel.

Abstract: Method for determining the position or the orientation of an object using a magnetic field and corresponding device.

Abstract: The present invention is directed to a sprinkler head leveling for ensuring that the longitudinal axis of a sprinkler head assembly is substantially vertically aligned. The sprinkler head leveler uses a hollow cylindrical base which slides over the sprinkler head bonnet and external casing after the sprinkler head is inserted in the ground. A bull's-eye level is mounted to the base and disposed above a top surface of the base to provide clearance from the attachment hardware and embossments on the top of the sprinkler head assembly. In this way, the leveling device can be used to vertically align the sprinkler head assembly without interference from the surface of the bonnet and the surrounding ground.

Abstract: An inclinometer for providing two different, direct readings corresponding to the angle of inclination of a worksurface includes a pair of parallel gauging surfaces engageable with the worksurfaces in first and second distinct positions. The inclinometer includes a body which defines the gauging surfaces, and a pointer is mounted to the body and is biased toward a predetermined orientation when either gauging surface is placed on the worksurface. The body carries two differently calibrated scales, one of which is oriented so as to interact with the pointer when a first one of the gauging surfaces rests on the worksurface and the other of which interacts with the pointer to provide a second reading when a second one of the gauging surfaces is placed on the worksurface. The scales may be calibrated to provide an angle reading and a pitch reading, and are preferably applied to a cover plate which overlies a cavity defined by the body within which the pointer is pivotably mounted.

Abstract: The invention provides a method and a device for positioning a dart board and an associated throwing line (hockey) without reference to the slope of the floor or the verticality of the wall (on which the board is mounted), or on the planarity of either. The primary advantage of the device is that inaccuracies in the level of the floor and the angle between the floor and the wall do not effect the measurement; another advantage is that the device allows the positioning to be done by a single person. The device includes two measuring lines connected (virtually) at right angles with means for leveling the throwing distance line, means for measuring the board elevation, means for attaching to the board and/or a board mounting bracket, and means for locating the hockey.
