  • Publication number: 20240314994
    Abstract: A system for dismantling defective BGA chips from double-sided PCBA having a fix stage and a cooling stage. The fix stage includes at least one shield that prevents hot air from a hot air gun to heat BGA chips that are adjacent to the defective BGA chips. The cooling stage prevents overheating of the BGA chips that are on the opposite side of the double-sided PCBA by conducting heat away from the BGA chips during the process.

  • Patent number: 8579170
    Abstract: An air breathing battery apparatus is connected to the hollow tubing of a backpack frame to provide an uninterrupted, water-resistant, light-weight power supply during extended remote operations in the field. Air breathing power sources are connected to the hollow tubes of the backpack assembly to provide a constant uninterrupted air supply in a relatively small package that fits easily into the backpack frame with only negligible added weight. The positioning of the air breathing power source in a backpack composed of hollow tubing also protects the battery from inclement weather or when the user is in water, for example, while fording a river or stream, to permit the uninterrupted use of the electronics powered by the battery.

  • Patent number: 7908957
    Abstract: A synchronized ammunition container apparatus and system is provided with a weapon, rotating automatic arm, ammunition container, and rotatable turret base that allows an anti-aircraft weapon, to traverse, depress and elevate in order to engage a rapid, head-on, fly-over target. The synchronized ammunition container apparatus synchronizes the movement and position of the rotating automatic single arm, ammunition container and rotatable turret base to insure that the ammunition belt will not twist, tangle or break when the weapon follows a rapid, head-on, fly-over target. The synchronized ammunition container system and apparatus gives the user increased flexibility for multiple deployment locations and engaging multiple targets from different directions. Other embodiments include a synchronized anti-aircraft ammunition container and combining the apparatus and anti-aircraft weapon into an integrated anti-aircraft defense system with the synchronized ammunition container.
