Abstract

Some examples of a cable cutting system include a first cutting apparatus that includes a recess to receive a cable. The system includes a second cutting apparatus separate from and attached to the first cutting apparatus. The second cutting apparatus includes multiple cutting surfaces arranged to cut the cable received at the recess.

First claim

What is claimed is:

1. A cable cutting system for a vehicle comprising:
a first cutting apparatus comprising a recess to receive a cable and a first cutting surface positioned in the recess, wherein the recess is disposed between a first guiding surface and a second guiding surface, and the first guiding surface is affixed to a surface of the vehicle; and
a second cutting apparatus separate from and attached to the first cutting apparatus, the second cutting apparatus comprising: a first cutting member comprising a first cutting surface and a second cutting member comprising a second cutting surface, the first cutting surface and the second cutting surface to continuously move to cut the cable, and a movement generator connected to the first cutting member and the second cutting member, the movement generator to continuously move the first cutting surface and the second cutting surface in response to receiving the cable between the first cutting member and the second cutting member.

2. The system of claim 1 , wherein:
the movement generator is a torsion spring or an electric motor; or
the movement generator moves the first cutting surface and the second cutting surface at a speed based on a forward velocity of the vehicle; or
each of the first cutting surface and the second cutting surface comprise serrated edges arranged on a loop.

3. The system of claim 1 , further comprising a sensor connected to the first cutting member, the second cutting member or both cutting members, the sensor to provide a signal to the movement generator in response to receiving the cable between the first cutting member and the second cutting member.

4. The system of claim 3 , wherein the sensor comprises a piezoelectric device.

5. A method to cut a cable encountered by a vehicle comprising:
providing a cable cutting system comprising a first cutting apparatus and a second cutting apparatus, the first cutting apparatus comprising a recess to receive a cable and a cutting surface positioned in the recess, wherein the recess is disposed between a first guiding surface and a second guiding surface, and the first guiding surface is affixed to a surface of the vehicle, a second cutting apparatus separate from and attached to the first cutting apparatus, the second cutting apparatus comprising: a first cutting member comprising a first cutting surface and a second cutting member comprising a second cutting surface, the first cutting surface and the second cutting surface to continuously move to cut the cable, and a movement generator connected to the first cutting member and the second cutting member, the movement generator to continuously move the first cutting surface and the second cutting surface in response to receiving the cable between the first cutting member and the second cutting member;
receiving the cable in the recess formed in the first cutting apparatus; and
cutting the cable using the second cutting apparatus.

6. The method of claim 5 , further comprising applying a force on the first and second cutting surfaces of the second cutting apparatus to cut the cable.

7. The method of claim 5 , further comprising cutting the cable using the plurality of cutting surfaces positioned in the recess of the first cutting apparatus.

8. The method of claim 5 , wherein:
the movement generator comprises a torsion spring or an electric motor;
the movement generator moves the first cutting surface and the second cutting surface at a speed based on a forward velocity of the vehicle; or
each of the first cutting surface and the second cutting surface comprise serrated edges arranged on a loop.

9. The method of claim 5 , further comprising providing a signal to the movement generator in response to receiving the cable between the first cutting member and the second cutting member using a sensor connected the first cutting member, the second cutting member or both cutting members.

10. The method of claim 9 , wherein the sensor comprises a piezoelectric device.
