G-force measurement system with a horizontally deviated accelerometer

Abstract

An acceleration measuring device to offset the limiting factors associated with the maximum acceleration an accelerometer can measure by attaching the device onto a mount system pre-calibrated to a specified angle relative to the horizontal axis of the object on which the system is mounted on.

Claims

1. A G-force measurement apparatus to measure the force of acceleration created by a device due to an acceleration along a horizontal direction, the apparatus comprising: an accelerometer; and a housing to receive the accelerometer, wherein a mounting surface is formed at a bottom portion of the housing to horizontally mount the apparatus onto a horizontal surface of the device along the horizontal direction of the acceleration, wherein the accelerometer is disposed in the housing, on a horizontal plane surface with respect to the mounting surface, wherein the accelerometer is horizontally deviated from the horizontal direction of the acceleration by a predetermined angle (), so that the accelerometer measures a deviated acceleration along a direction that is horizontally deviated from the horizontal direction of the acceleration by the predetermined angle (), and further wherein the G-force is obtained by dividing the measured deviated acceleration by cos (e) and multiplying the result by a mass of the device.

DETAILED DESCRIPTION OF DRAWINGS

(9) The following descriptions are set forth and have been assigned numerical designations to enable the reader to understand the reasoning behind and the application of the present invention. Even though specific configurations are shown, it should be noted that these are merely for illustrative purposes and the following figures show only one method of implementation and will be apparent to those skilled in the art that there are other similar methods and applications of the invention.

(10) The following figures use a firearm hand guard as the measurable device.

(11) FIG. 1 illustrates the present invention (1), Angled Acceleration Measurement System, and its key components; accelerometer (2) and mounting apparatus system (3).

(12) FIG. 2 illustrates the present invention (1), with a transparent top surface, showing the accelerometer (2) situated at a predetermined direction (5) relative to the linear direction of motion (4) to create the angle theta (6).

(13) FIG. 3 is an illustration of the present invention (1) attached via mounting apparatus system (3) onto a measurable device (7). This illustration also shows the accelerometer (2) at a predetermined direction (5) relative to the direction of motion (4).

(14) FIG. 4 and FIG. 5 illustrates a partial view of the present invention (1) from opposing viewpoints. FIG. 4 is in front of the direction of motion (4) while FIG. 5 is behind the direction of motion (4).

(15) Both figures show measurable device (7), mounting apparatus system (3), and the relative direction of the accelerometer (5).

(16) FIG. 6, similar to FIG. 1 is an illustration showing an example of how the present invention will function. In this figure, a maximum force of 1000N (4) is used with X as the maximum force the accelerometer (5) can record. Due to the resultant angle between the predetermined direction (5) relative to the linear direction of motion (4) the angle theta (6) is created. The calculations are as follows; 1000N is force that the measurable device (7) creates. From geometry and trigonometric functions, cos =adjacent force multiplied by 1/hypotenuse.

(17) Therefore, cos =X multiplied by 1/1000 N. Resulting in X=1000N cos .

(18) If we use a resultant theta (6) of 60, the calculation will be X=1000N multiplied by 0.500.

(19) Therefore, X will read 500N.

(20) This means that a 500N maximum reading rated accelerometer (2) can read 1000N due to the angle created by the aforementioned predetermined direction (5) relative to the linear direction of motion (4).
