Abstract: A microcontroller has a CPU with at least one interrupt input coupled with an interrupt controller, a plurality of peripherals, and a mode register comprising at least one bit controlling an operating mode of the microcontroller. The microcontroller is configured to operate in a first operating mode wherein upon assertion of an interrupt by a peripheral of the microcontroller, the interrupt controller forwards an interrupt signal to the CPU and the peripheral sets an associated interrupt flag, wherein the interrupt causes the CPU to branch to a predefined interrupt address associated with the interrupt input. In a second operating mode, upon assertion of an interrupt by a peripheral of the microcontroller, the interrupt controller forwards an interrupt signal to the CPU and the CPU receives additional interrupt information from the peripheral that generated the interrupt, wherein the additional interrupt information is used to generate a vector address.

Abstract: In a gun tube for firing rounds of smart ammunition, a sensor means applied to the ammunition which enables the calculation of muzzle velocity in the instant as the ammunition leaves the muzzle edge of the gun tube. The sensor relies on measurement of magnetic field induced voltages which are unique as the ammunition leaves the muzzle edge of the gun tube. Each round of ammunition has a planar transformer of wiring applied longitudinally on the side of the round, which aids in creating the necessary magnetic fields.

Abstract: The invention relates to remotely controlling a number of devices on an instrument mounted on a rotating assembly without physical contact to the assembly. A series of infrared light-emitting diodes mounted in a stationary ring configuration are placed around (but not directly touching) the rotating assembly to send control signals to infrared receiver devices located on the assembly. The rotating assembly might be the turret of a conventional Common Remotely Operated Weapons Station (CROWS), the invention to replace convention internal slip-ring providing power and control to a gun on the CROWS. The infrared data links of this invention do not inhibit the movement of the rotating assembly, and further are not susceptible to radio-jamming by electronic warfare countermeasures. Additionally, the invention includes a mount that allows auxiliary devices with Picatinny Rails™ to also be attached to such a CROWS turret.
