Abstract
An apparatus for detonating an explosive body associated with a downhole tool includes a plurality of firing heads, each firing head including an initiating explosive body generating a high-order input when detonated; and a funnel configured to detonate the explosive body associated with the downhole tool by using a single high-order output. The funnel has a body that includes: a plurality of input openings, each input opening positioned next to an associated initiating explosive body to receive the generated high-order input, a single output opening, and a flow path connecting the plurality of input openings with the single output opening.

An apparatus for detonating an explosive body associated with a downhole tool, comprising:
- a plurality of firing heads, each firing head including an initiating explosive body generating a high-order input when detonated;
- and
- a funnel configured to detonate the explosive body associated with the downhole tool by using a single high-order output, the funnel having a body that includes:
- a plurality of input openings, each input opening positioned next to an associated initiating explosive body to receive the generated high-order input,
- a single output opening, and
- a flow path connecting the plurality of input openings with the single output opening.
An apparatus for detonating an explosive body associated with a downhole tool, comprising:
- a plurality of side-by-side firing heads, each firing head including an initiating explosive body generating a high-order input when detonated;
- a funnel having a body that includes:
- a plurality of input openings, each input opening being positioned next to an associated initiating explosive body to receive the generated high-order input, wherein each input opening is in communication with an associated passage,
- a juncture connecting the associated passages of the plurality of input openings,
- a single output passage having a first end connected to the juncture and a second end, and
- a single output opening formed at the second end of the single output passage.
