| 20110119942 | SENSOR AND METHOD FOR MOTION MEASUREMENT OF CO-EXISTING TILT AND HORIZONTAL ACCELERATION - A motion-sensing device for sensing tilt and acceleration when either tilt, horizontal acceleration, or tilt and horizontal acceleration acting concurrently, influence the device, including: a substrate, a first tilt sensor fixed to the top of the substrate; a pendulum flexibly coupled to the bottom of the substrate proximate to the first tilt sensor; and a second tilt sensor fixed to the pendulum. The first and/or second tilt sensors are preferably an accelerometer; a spring-mass system; and/or an arcuate resistive element. The first tilt sensor includes a tilt sensor that measures tilt in a first geometric plane, the pendulum is constrained to move in the first geometric plane, and the second tilt sensor is operable to measure tilt in the first geometric plane. The motion-sensing device or devices coupled to a machine, vehicle, and/or a control system. The substrate may include a portion of the first tilt sensor. | 05-26-2011 |

| 20090106991 | Support assembly for a counter weight of a laser level - A support assembly for a counter weight of a laser level is disposed in a main body of the laser level for supporting the counter weight with a laser module mounted therein in the main body. The support assembly includes a fixing unit and a universal bearing. The fixing unit is disposed in the main body and the universal bearing is mounted in the fixing unit. The counter weight has a shaft portion formed on an upper end thereof and connected with the universal bearing. The counter weight is swingingly supported in the main body by the universal bearing. Basing on the structure, the present invention has a simple structure for easy assembly and disassembly, thereby being manufactured, maintained and corrected conveniently. | 04-30-2009 |
| 20130111771 | Plumb device for constructing brick columns - A device for constructing plumb brick columns includes: (a) a base suspension portion including: a base, a base pole, and a substantially L-shaped swing arm movably attached to the base pole; (b) a hanger mechanism, including a hanger rod attached to a center of the upper template, and to a hanger clamp that is affixable around the swing arm; and (c) a suspended template portion including: (1) an upper template; (2) a same-sized, removable lower template below the upper template; and (3) vertical guide lines, each extending between a corner of the upper template and a corresponding corner of the lower template, each corner of the lower template including a line attachment device attachable to a corresponding attachment device on a lower end of each guide line. This simplified abstract is not intended to limit, and should not be interpreted as limiting, the scope of the claims. | 05-09-2013 |

| 20100186246 | Inclination sensor - To be able to measure the angular deviation simultaneously in two directions in space a magneto-sensitive sensor unit on the one hand (that can measure the magnetic flux density in at least two directions in space or orthogonal to each other) and a magnet on the other hand are moved relatively to each other, wherein one of both elements are provided in such a way that it aligns itself directly or indirectly according to the gravity. An optimal measuring result is achieved by guiding one of both elements on a defined, reproducible surface so that the center axis of this element is directed always to the center axis of the other element. | 07-29-2010 |

| 20100218392 | LEVEL MEASURING DEVICE - A level measuring device for measuring the level of a surface includes a support, a first pivot shaft, a second pivot shaft, a pendulum, a first rotation sensor, a second rotation sensor and a computing module. The support includes a bottom surface which is configured for contacting the surface. The first pivot shaft is rotatably supported by the support. The second pivot shaft is rotatably linked to the first pivot shaft and perpendicular to each other. The pendulum is suspended from the second pivot shaft. The first rotation sensor and the second rotation sensor are configured for sensing rotated angle and direction of the first pivot shaft and the second pivot shaft, caused by the displacement of the pendulum. The computing module is configured for calculating the level of the surface using the rotated angle and direction. | 09-02-2010 |
| 20150040412 | INCLINOMETER - An inclinometer for measuring a change in the inclination of a structure from a given initial position. The inclinometer comprises a frame, a pendulum and at least three distance-measuring device. The frame is rigidly connected to the structure such that the inclination of the frame has the same changes in inclination as the structure. The pendulum is freely suspended from the frame and comprises a first end attached to the frame and a freely moving opposite end. The distance-measuring devices at the frame have respective coplanar measuring axes converging at a single point. Each measuring device measures a change in the distance separating same from the pendulum. | 02-12-2015 |
