The invention provides transgenic animals comprising a lentiviral transgene, such as an HIV transgene. Also within the scope of the invention are cells and eggs from the transgenic animal. Further included are methods for identifying therapeutic compounds for preventing lentiviral infection and treating associated disease (e.g. AIDS).

A dual signature arming mechanism responsive to acceleration to cock a fig pin and responsive to propellant combustion gas pressure to pyrotechnically release a pivotally mounted detonator which rotates into position relative to said firing pin. A plunger restrained by the pyrotechnic release is provided to disable the arming mechanism if the pyrotechnic release is activated before a specific velocity is reached.

This invention makes use of the gas that escapes past a shell as it emerges rom a gun barrel to provide a safety and arming device. This gas is electrically active and has the properties of a plasma. Electrical charge from this gas accumulates on the surface of the projectile as it exits from the barrel. This accumulation takes place at the muzzle of the gun tube since the projectile is effectively grounded as it travels up the tube. The invention utilizes a specifically adapted capacitor to accumulate this charge and arm the fuze. Arming is provided by detecting a particular threshold of the charge on the capacitor and utilizing a standard "AND", "OR", or "NOR" gate to make the decision whether or not to initiate a standard mechanical arming mechanism.
