    Abstract: An ammunition cartridge for a gun is optically initiated by a mechanism wholly within the cartridge case itself. The case has as optical primer initiation means producing light fluence to ignite a primer, which ignited primer may in turn ignite into a flashtube, and which ignited flashtube may in turn ignite a bed of propellant in said cartridge. The optical primer initiation means may be an LED, a laser diode, a VCSEL, or some other light emitting device in general. The cartridge optically initiated primer package is so sized and made electrically and mechanically seamlessly physically compatible with current ammunition cartridges such that these new cartridges are completely interchangeable. If the cartridge primer initiation means is of a percussion type, the cartridge is adapted to include an in-line piezoelectric crystal so that electrical power will be generated when the cartridge assembly is struck by a firing pin during percussion type operations; the power is then used to initiate the light emitting device.

    Abstract: A projectile which can be used to defeat an unmanned aerial system. The projectile features sabots which do not impart any forward impedance to the sub-projectiles, and carries a payload of stacked rings enclosed in the projectile. The rings are backed by a support ring, and abut a pusher aft section. The projectile's sabots discard cleanly upon muzzle exit, releasing the ring sub-projectiles to cover a large area, thereby increasing the probability of impacting the target. The rings create large holes in the target, despite comparatively low mass of a given ring as a defeat element, allowing for multiple sub-projectiles to be fired with a single shot, thereby creating the effect of firing multiple projectiles with a single shot.

    Abstract: An embodiment of the invention provides a method including obtaining ultrasonic images of one or more vessel to be catheterized with an ultrasonic imaging device 212 and identifying the center(s) of the vessel(s) with the ultrasonic images. One of the vessels is punctured with a needle 220 based on the identifying of the center of the vessel. A guide wire 230 is inserted into the vessel and maneuvered with guide wire ultra-sonic feedback control. The guide wire ultra-sonic feedback control includes obtaining ultrasonic images of the vessel and the guide wire 230 in the vessel, and displaying the ultrasonic images of the vessel and the guide wire 230 in the vessel to a user. A catheter sheath 240 is inserted over the guide wire 230 and maneuvered with sheath ultrasonic feedback control. The guide wire 230 is removed and a catheter 250 is inserted into the catheter sheath 240 and maneuvered with catheter ultrasonic feedback control.
