Abstract
Abstract The telecoordinometer (1) is capable of detecting the movements and/or the oscillations of a structure (8) it is associated with. It comprises an absolute reference element constituted by an either horizontally or vertically taut line (2, 2A) and a detection apparatus (3, 3A) integrally affixed to the monitored structure (8), capable of detecting the movements and/or the oscillations according to at least one direction of said taut line (2, 2A) relatively to the structure (8).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
221 words
A device for detecting displacement of a structure, wherein the device comprises an absolute reference element having a main axis and detection means for detecting the position of the structure relative to the absolute reference element, wherein the structure is attached to the earth, and wherein the device comprises: a) a relative reference element fixedly attached to the structure and positioned between the absolute reference element and the detection means, wherein said relative reference element comprises: 1) a first pin having a main axis, wherein said main axis of said first pin is parallel to the main axis of the absolute reference element, and 2) a second pin having a main axis, wherein said main axis of said second pin is parallel to the main axis of the absolute reference element; wherein said first pin and said second pin are on opposite sides, one from the other, of the absolute reference element and wherein the distance between said first pin and said second pin represents a sample distance for calibrating the detection means so that the detection means detects the position of the structure relative to the absolute reference element by detecting changes in the distance between the absolute reference element and at least one of said pins and the detection means calibrates and checks itself by detecting said sample distance.
Claim 2
Independent Claim
221 words
A device for detecting displacement of a structure, wherein the device comprises an absolute reference element having a main axis and detection means for detecting the position of the structure relative to the absolute reference element, wherein the structure is attached to the earth, and wherein the device comprises: a) a relative reference element fixedly attached to the structure and positioned between the absolute reference element and the detection means, wherein said relative reference element comprises: 1) a first pin having a main axis, wherein said main axis of said first pin is parallel to the main axis of the absolute reference element, and 2) a second pin having a main axis, wherein said main axis of said second pin is parallel to the main axis of the absolute reference element; wherein said first pin and said second pin are on opposite sides, one from the other, of the absolute reference element and wherein the distance between said first pin and said second pin represents a sample distance for calibrating the detection means so that the detection means detects the position of the structure relative to the absolute reference element by detecting changes in the distance between the absolute reference element and at least one of said pins and the detection means calibrates and checks itself by detecting said sample distance.
Claim 3
Dependent Claim
28 words
The device of claim 1, further comprising positioning means for trueing the device, wherein said positioning means is positioned between the detection means and said relative reference element.
Claim 4
Dependent Claim
71 words
The device of claim 2, wherein the detection means comprises and emitting means attached to the device for emitting a signal and a receiving means attached to the device for receiving said signal, wherein said emitting means and said receiving means are on opposite sides, one from the other, of the absolute reference element and wherein said pins are interposed between said emitting means and said receiving means for detection thereby.
Claim 5
Dependent Claim
70 words
The device of claim 3, wherein said signal comprises a light source and said emitting means further comprises a diaphragm attached to said omitting means for controlling the output of said signal, a focusing means attached to said emitting means for focusing said signal, a collimating means attached to said emitting means for focusing said signal, and protecting baffles attached to said emitting means for protection of said emitting means.
Claim 6
Dependent Claim
25 words
The device of claim 4, wherein said emitting means further comprises a right angle prism attached to said emitting means for redirecting said signal 90°.
Claim 7
Dependent Claim
15 words
The device of claim 3, wherein said receiving means comprises at least one CCD array.
Claim 8
Dependent Claim
26 words
The device of claim 3, wherein said receiving means comprises a plurality of CCD arrays, wherein said plurality of CCD arrays are positioned alongside one another.
Claim 9
Dependent Claim
81 words
The device of claim 2, wherein said positioning means comprises at least three male elements and at least three female elements for coacting with said male elements, wherein each of said male elements comprises a non-aligned spherical end, and wherein each of said female elements comprise a cone shaped hollow, a cylindrical hollow aligned with said cone shaped hollow, and a groove having a triangular cross section aligned with said hollows for accepting said end of each of said male elements.
