A robust air gun fire time sensor consists of a housing to which is secured a protruding nonmagnetic internal barrel having a bore. The bore is closed at one end by a magnetic end cap defining an air chamber and the bore is in fluid communication with the firing chamber of an air gun. A generator coil surrounds the barrel. A bar magnet is floatingly mounted inside the bore and is urged against a shoulder formed in the end cap. When the air gun is charged with compressed air, some of the air becomes entrapped in the air chamber. When the air gun is fired, the entrapped compressed air in the air chamber pushes the bar magnet away from the shoulder. The collapsing magnetic field creates a transient electric pulse in the generator coil.       Recently Added Patents Cervical spine protection collar for contact and non-contact activities Vehicular box structure Container Method for geophysical and geological interpretation of seismic volumes using chronological panning Electromagnetic lock Conflict resolution apparatus Stabilizer, and method of producing a stabilizer   Randomly Featured Patents Vehicle restraint system for the handicapped Low oxygen cubic boron nitride and its production Fixed loading roller attachable to a vehicle rack Power saving methods for programmable logic arrays Wall mounted soap dish Radio communication device Mounting bracket for an electrical connector IC tag administration device, robot including the IC tag administration device, and IC tag administration method Method of surface plasmon resonance (SPR) to detect genomic aberrations in patients with multiple myeloma Method for adjusting idling RPM of engine © 2006-2008 PatentGenius.
