摘要： A magnetic compass is provided which features a stationary central pointer which extends outwards to the inside of a rim displaying graduated angular indicia, said rim being integral with a pivoting disc which is magnetically coupled. The central pointer assumes the graphic shape of a craft, such as a ship's hull, the stationary disposition of which offers a more intuitive realization of the directional heading of a vessel with respect to the cardinal axes of a compass.

摘要： A self-balancing, no-spin magnetic compass. A described embodiment includes a compass card assembly, a retainer assembly, a pivot assembly, a gimbal assembly, a cup, and a dome. The compass card assembly includes an air chamber which provides buoyancy. The retainer assembly functions with the compass card assembly to retain magnets. The pivot assembly snap-fits into the retaining assembly and contacts the compass card assembly to allow the compass card assembly to pivot about the pivot assembly. The pivot assembly also snap-fits into the gimbal assembly. The base of the pivot assembly is positioned into the cup and the entire compass is secured into the dome, that is filled with a fluid.

摘要： A three-dimensional homologous surveying instrument includes a base with an outer spherical shell mounted thereon for receiving therein a ring-shaped shell holder, an intermediate spherical shell and an inner spherical shell with respective zero references at in a homologous relationship with each other. The inner spherical shell rotates within the intermediate spherical shell about X-axis. The intermediate spherical shell rotates within the ring-shaped shell holder about Y-axis. The outer spherical shell is positioned in the base to serve as the X-axis. The inner spherical shell and the intermediate spherical shell each have a pendulum at the bottom. The outer spherical shell, the ring-shaped shell holder, the inner spherical shell and the intermediate spherical shell form a gyroscopic device for three dimensional surveying through X-axis, Y-axis and Z-axis concomitantly. The pendulum of the inner spherical shell is mounted with a compass for indicating the direction of the angle of slope being surveyed.

摘要： The balancing righting moments and dampening of the compass card and directive magnets in a liquid damped magnetic compass are separated to reduce the tilt and oscillation of the compass card when subjected to lateral acceleration, such as pitching and rolling in a seaway. The compass card is connected to the pivoted directive magnetic assembly by a card gimbal arrangement. The compass card is connected to the outer side of the gimbal ring rotating on a first axis. The magnetic assembly is connected to the inner side of the gimbal ring for rotation along a second axis oriented 90 degrees from the first axis.

摘要： A system and method indicate the direction faced by an operator. A waterproof housing has a mounting mechanism to engage a part of a headgear worn by an operator to position the housing in a portion of the operator's forward field of view. A two-axis gimbal mechanism is inside the waterproof housing and has a protective housing connected to the waterproof housing. The protective housing contains ring structure coupled to two orthogonal axis structures. A magnetic field sensor module is mounted on one of the axis structures and provides magnetic field data signals representative of the direction faced by the operator. An optical element has a wide field of view to transmit compass data images representative of the magnetic field data signals to the eyes of the operator.

摘要： A fluxgate compass direction sensor in which a fluxgate is mounted relative to a receptacle by means of a flexible circuit. The fluxgate is also suspended in a liquid by means of a float. In use, if the receptacle tilts relative to the horizontal, the level of the liquid will move to retain a horizontal aspect and the float, being buoyant in the liquid, will retain the fluxgate in the horizontal plane. The flexible circuit acts to allow tilting of the float and fluxgate relative to the receptacle while retaining the fluxgate in lateral and directional alignment relative to the receptacle.
