Abstract

An image sensing assembly includes an enclosure that defines a first viewport aperture in a front wall of the enclosure. The image sensing assembly includes a first image sensor attached within the enclosure, the first image sensor aligned with the first viewport aperture in the front wall of the enclosure to capture image data representative of a scene viewed through the first viewport aperture. The image sensing assembly includes a bracket attached to the enclosure at a first portion of the bracket and attached to a first mounting plate at a second portion of the bracket. The image sensing assembly includes a vibration dampening mount located between the bracket and the first mounting plate to at least partially isolate the enclosure from vibration of the first mounting plate.

First claim

What is claimed is:

1. An image-sensing assembly, comprising:
an enclosure that defines a first viewport aperture in a front wall of the enclosure;
a first image sensor attached within the enclosure, the first image sensor aligned with the first viewport aperture in the front wall of the enclosure to capture image data representative of a scene viewed through the first viewport aperture;
a thermally conductive plate that defines a second viewport aperture, the thermally conductive plate attached within the enclosure between (i) a structure to which the first image sensor is attached, and (ii) the front wall of the enclosure, such that the second viewport aperture in the thermally conductive plate aligns with the first image sensor and the first viewport aperture in the front wall of the enclosure;
a heating element thermally connected to the thermally conductive plate;
a bracket attached to the enclosure at a first portion of the bracket and attached to a first mounting plate at a second portion of the bracket; and
a vibration dampening mount located between the bracket and the first mounting plate to at least partially isolate the enclosure from vibration of the first mounting plate.

2. The image-sensing assembly of claim 1 , wherein:
a back wall of the enclosure defines multiple bracket fastening apertures; and
the bracket is removably attached to the enclosure at the back wall of the enclosure using multiple bracket fastening fasteners that pass through the multiple bracket fastening apertures.

3. The image-sensing assembly of claim 2 , wherein:
the first portion of the bracket is angled with respect to the second portion of the bracket at a first angle; and
the back wall of the enclosure is angled with respect to the first mounting plate at the first angle.

4. The image-sensing assembly of claim 3 , wherein:
the first angle is approximately 90 degrees;
the enclosure includes a side wall located between the front wall of the enclosure and the back wall of the enclosure; and
the first mounting plate is oriented parallel to the side wall of the enclosure.

5. The image-sensing assembly of claim 3 , wherein:
the image-sensing assembly further comprises a second mounting plate removably attached to the first mounting plate with multiple mounting plate fastening fasteners;
the first mounting plate, the second mounting plate, and the multiple mounting plate fastening fasteners form a sandwich mount; and
the first mounting plate and the second mounting plate are oriented parallel to each other.

6. The image-sensing assembly of claim 3 , wherein:
the image-sensing assembly further comprises a second mounting plate and a third mounting plate that are attached to the first mounting plate with a bracket;
the second mounting plate is removably attached to the third mounting plate with multiple mounting plate fasteners; and
the second mounting plate, the third mounting plate, and the multiple mounting plate fasteners form a sandwich mount.

7. The image-sensing assembly of claim 6 , wherein:
the second mounting plate and the third mounting plate are oriented parallel to each other; and
the first mounting plate is oriented perpendicular to both the second mounting plate and the third mounting plate.

8. The image-sensing assembly of claim 1 , wherein:
the enclosure includes a front portion and a rear portion releasably attachable to each other to enclose an interior of the enclosure;
the image-sensing assembly further comprises a gasket to seal the front portion of the enclosure to the rear portion of the enclosure, the gasket surrounding the interior of the enclosure;
the enclosure defines multiple enclosure fastening apertures;
the image-sensing assembly further comprises multiple enclosure fastening fasteners that pass through the multiple enclosure fastening apertures to releasably attach the font portion of the enclosure to the rear portion of the enclosure; and
the multiple enclosure fastening fasteners are positioned outside of the gasket such that the multiple enclosure fastening apertures are positioned outside the interior of the enclosure.

9. The image-sensing assembly of claim 1 , wherein:
the enclosure defines a second viewport aperture in the front side of the enclosure;
the image-sensing assembly further comprises a second image sensor attached within the enclosure; and
the second image sensor is aligned with the second viewport aperture in the front side of the enclosure.

10. The image-sensing assembly of claim 1 , wherein:
the structure to which the first image sensor is attached comprises a first circuit board, the first circuit board located within the enclosure and removably attachable to the front wall of the enclosure with multiple structure fastening fasteners;
the image-sensing assembly further comprises wireless transmission circuitry to transmit the image data captured by the first image sensor;
the image-sensing assembly further comprises a second circuit board to which the wireless transmission circuitry is attached, the second circuit board located within the enclosure and removably attached to a back wall of the enclosure opposite from the front wall of the enclosure with multiple second circuit board fastening fasteners; and
the enclosure includes a front portion and a rear portion releasably attached to each other, the front portion including the front wall and the rear portion including the rear wall.

11. The image-sensing assembly of claim 10 , further comprising a communication cable that communicatively connects the first circuit board to the second circuit board to transmit the image data captured by the first image sensor to the wireless transmission circuitry, the communication cable being releasably attached to the first circuit board or the second circuit board.

12. The image-sensing assembly of claim 11 , wherein:
the rear portion of the enclosure defines an antenna receiving aperture; and
the wireless transmission circuitry includes an antenna that communicatively connects to the second circuit board and that extends through the antenna receiving aperture so that at least part of the antenna is located external to the enclosure.

13. The image-sensing assembly of claim 12 , wherein:
the rear portion of the enclosure defines a power-supply receiving aperture;
the image-sensing assembly further comprises a power supply cable or terminal to receive power from a power source external to the enclosure; and
the power supply cable or terminal extends at least partially through the power-supply receiving aperture.

14. The image-sensing assembly of claim 1 , wherein the thermally conductive plate is attached within the enclosure between the first image sensor and the front wall of the enclosure.

15. The image-sensing assembly of claim 14 , further comprising a transparent panel positioned between the image sensor and the front wall of the enclosure, the transparent panel aligned with the first image sensor, the first viewport aperture in the front wall of the enclosure, and the second viewport aperture in the thermally conductive plate.

16. The image-sensing assembly of claim 15 , wherein the transparent panel is positioned between the front wall of the enclosure and the thermally conductive plate.
