摘要:
An apparatus and methodology for measuring strike and dip of a plane, trend and plunge of a line, directional bearing in the horizontal plane, and angle of inclination in the vertical plane. More specifically, the present invention relates to a compass adapted to measure geological features using single compass configurations for each type of measurement. The compass includes a base, a hinge assembly rotatably interconnected to the base, and a lid rotatably interconnected to the hinge assembly. The lid is operable to rotate around both a major axis and a minor axis of the compass. A sight tube is positioned in a hollow bore of the hinge assembly and is operable to sight directional bearings.

A clinometer including a base plate and a compass which is mounted on the base plate and can measure a strike and a dip angle. The compass includes a first case which is rotationally provided on the base plate so as to move a strike scale indicated on the rim of the compass to a certain position and a second case which is provided in the first case, and which is fixed on the base plate so as to fix a dip scale indicated on the rim of the compass at a certain position.

A method for calculating an angle of inclination of a magnetic field in a sensor coordination system includes measuring a magnetic field vector using a magnetometer, measuring an acceleration vector using an accelerometer, determining whether the sensor coordination system is in a moving state or a stationary state using the acceleration vector, and calculating the inclination angle of the magnetic field using the magnetic field vector and the acceleration vector, in response to the determining indicating the stationary state.

An apparatus for measuring geologic strike and dip of a formation. The apparatus includes a support plate, a first rotation plate disposed on the support plate and parallel to the support plate, the first rotation plate being rotatable parallel to the support plate, a second rotation plate hinge-coupled to the first rotation plate, the second rotation plate being rotatable about a hinge shaft, a protractor configured to read an angle between the first rotation plate and the second rotation plate; and a measuring unit including a compass disposed on the second rotation plate.

A clinometer apparatus includes a first measurement member, a second measurement member, and a coupling member. The first measurement member includes a first plate on which first angle indices are formed, and a first coupling unit that has a circumferential surface on which second angle indices are carved. The second measurement member includes a second plate, a second coupling unit that is coupled to the first coupling unit due to the coupling member, and a compass that is coupled to the second plate. The coupling member couples the first coupling unit and the second coupling unit so that the second measurement member rotates relative to the first measurement member about a rotational axis of the first coupling unit.

This invention relates to an attitude meter which measures the orientation of a plane surface with respect to the magnetic North direction and a horizontal plane. The meter includes a hollow transparent sphere containing liquid for supporting a compass and a vertical indicator, combined with a rotatable arcuate scale for facilitating visual reading of the compass and relative position of the vertical indicator. More particularly, the arcuate scale includes vertical orientation indicia and is mounted for rotational displacement to a position immediately adjacent the vertical indicator. By this arrangement the vertical angle of the surface being measured may be read directly from the arcuate scale and the direction of inclination relative to the magnetic North may be determined from the point of intersection of the arcuate scale and the liquid supported compass.
