An axial piercing mechanism for a pressurized gas canister includes a housing, electric motor assembly, pushrod assembly, and lancet. The housing defines one or more radial exhaust ports and coaxial internal cavities. The electric motor assembly and pushrod assembly are disposed in the respective first and second cavities. The pushrod assembly is coupled to the electric motor assembly and is rotatably driven along the longitudinal axis thereby. The lancet is coupled to the pushrod assembly. The housing includes a second end that receives or couples to a sealed end of the pressurized gas canister proximate the lancet such that the electric motor assembly, when energized, causes the pushrod assembly and lancet to translate along the longitudinal axis, pierce a sealed end/diaphragm of the canister, and release pressurized gas through the exhaust port. A system includes the axial piercing mechanism and the pressurized gas canister.

1. An axial piercing mechanism for use with a canister containing pressurized gas and having a sealed end, the axial piercing mechanism comprising: a housing having a longitudinal axis and first and second ends, the housing defining at least one exhaust port, and further defining coaxial first and second internal cavities, wherein the second end is configured to receive or couple to the sealed end of the pressurized gas canister;an electric motor assembly disposed in the first internal cavity at the first end of the housing;a pushrod assembly disposed in the second internal cavity and having first and second ends, wherein the first end of the pushrod assembly is rotatably coupled to the electric motor assembly; anda lancet coupled to the second end of the pushrod assembly;wherein the electric motor assembly is configured to translate the pushrod assembly and the lancet along the longitudinal axis toward the sealed end in response to an input signal to thereby pierce the sealed end and release the pressurized gas from the gas canister through the at least one exhaust port. 2. The axial piercing mechanism of claim 1, wherein the first end of the housing is internally-threaded. 3. The axial piercing mechanism of claim 1, wherein the at least one exhaust port includes a pair of exhaust ports. 4. The axial piercing mechanism of claim 1, wherein the electric motor assembly includes an electric motor and a gearbox assembly having a plurality of gear elements, and wherein the pushrod assembly is rotatably coupled to one of the plurality of gear elements. 5. The axial piercing mechanism of claim 4, wherein the second internal cavity is internally threaded, and wherein the pushrod assembly defines external threads that engage the housing within the second internal cavity. 6. The axial piercing mechanism of claim 1, further comprising: a printed circuit board assembly configured to generate the input signal, wherein the housing contains the printed circuit board assembly at the first end. 7. The axial piercing mechanism of claim 1, wherein the first and second ends of the housing are externally-threaded, the axial piercing mechanism further comprising: a plurality of jam nuts threaded to the housing at one or both of the first and second ends of the housing. 8. The axial piercing mechanism of claim 7, wherein the plurality of jam nuts includes a first pair of jam nuts disposed at the first end of the housing and a second pair of jam nuts disposed at the second end of the housing, the axial piercing mechanism further comprising: a bracket having a pair of standoffs received between the jam nuts at the respective first and second ends of the housing. 9. The axial piercing mechanism of claim 7, further comprising: a bulkhead attachment defining an opening, wherein the plurality of jam nuts includes a pair of jam nuts disposed only at the first end of the housing, and wherein the bulkhead attachment is configured to receive the pair of jam nuts in the opening. 10. The axial piercing mechanism of claim 1, further comprising: a swivel elbow fitting having a first arm threaded into the exhaust port and a second arm, wherein the second arm is orthogonal to the first arm and is positioned in parallel with the longitudinal axis. 11. A system for delivering a compressed gas to a device, the system comprising: a pressurized gas canister containing the compressed gas, wherein the pressurized gas canister has a sealed end that is sealed with a diaphragm; andan axial piercing mechanism including: a housing having first and second ends and a longitudinal axis, wherein the housing defines an exhaust port extending radially from the longitudinal axis, and further defines coaxial first and second internal cavities;an electric motor assembly disposed in the first internal cavity at a first end of the housing and energized in response to an input signal;a pushrod assembly disposed in the second internal cavity and having first and second ends, wherein the first end of the pushrod assembly is rotatably coupled to the electric motor assembly, and wherein the pushrod assembly is configured to be rotatably translated along the longitudinal axis via the electric motor assembly when the electric motor assembly is energized; anda lancet coupled to the second end of the pushrod assembly;wherein the second end of the housing is configured to receive or couple to the sealed end of the pressurized gas canister proximate the lancet such that the electric motor assembly, when energized, causes the pushrod assembly and the lancet to translate along the longitudinal axis for a distance sufficient for piercing the diaphragm and releasing the pressurized gas through the at least one exhaust port and into the device. 12. The system of claim 11, further comprising: the device;a fitting positioned within the exhaust port; andtubing fluidly connecting the device to the exhaust port. 13. The system of claim 12, wherein the device is an inflatable float. 14. The system of claim 11, wherein the exhaust port includes a pair of exhaust ports. 15. The system of claim 11, wherein the electric motor assembly includes an electric motor and a gear box assembly having a plurality of gear elements, and wherein the pushrod assembly is rotatably coupled to one of the plurality of gear elements. 16. The system of claim 11, wherein the housing is internally-threaded within the second internal cavity, and wherein the pushrod assembly defines external threads that engage the housing within the internally-threaded second internal cavity. 17. The system of claim 11, further comprising: a printed circuit board assembly configured to generate the input signal, wherein the first end of the housing contains the printed circuit board assembly and the second end of the housing receives or couples to the sealed end of the pressurized gas canister. 18. The system of claim 11, wherein the first and second ends of the housing are externally-threaded, the system further comprising: a plurality of jam nuts threaded to the housing at one or both of the first and second ends of the housing. 19. The system of claim 18, wherein the plurality of jam nuts includes a first pair of jam nuts disposed at the first end of the housing and a second pair of jam nuts disposed at the second end of the housing, the system further comprising: a bracket having a pair of standoffs received between the jam nuts at the respective first and second ends of the housing. 20. The system of claim 18, further comprising: a bulkhead attachment defining an opening, wherein the plurality of jam nuts includes a pair of jam nuts disposed only at the first end of the housing, and wherein the bulkhead attachment is configured to receive the pair of jam nuts in the opening.
