A medium caliber polymer-based ammunition cartridge has an insert forming a base end and engaged to a polymer body forming an internal propellant chamber. The polymer body is engaged at its forward end to a polymer nose which has a shoulder that transitions directly into a projectile opening. The shoulder is inwardly radially thickened to increase lateral support about a medium caliber projectile loaded into the cartridge. The thickness of the shoulder may vary along its longitudinal length. One or more crush seals may be integrally formed about an outer surface of the cartridge nose. The crush seals include an annular tip seal and one or more annular shoulder seals. Each of the crush seals deform into an obturating ring to form a seal between the outer surface of the medium caliber polymer cartridge and the inner walls of the firing chamber.

A powder compaction device is disclosed. The device has a drive motor operable connected to a compaction rod that moves through a loading platform to a cartridge holding platform. A powder loading station is positioned below the loading platform and above the cartridge holding platform. The compaction rod moves through the powder loading station, which loads a predetermined volume of propellant powder into one or more reliefs defined in the compaction rod. The cartridge holding platform has a removable cartridge fixture designed to receive an ammunition cartridge to be loaded and compacted with propellant powder. The propellant powder is released into the cartridge fixture from the reliefs as the compaction rod passes a funnel defined at an upper end of the fixture. After releasing the powder, the compaction rod continues into an interior chamber of the fixture to compact the powder contained therein.

One embodiment of the present invention provides a polymeric ammunition cartridge and methods of making and using the same. The cartridge includes a substantially cylindrical insert connected to a substantially cylindrical polymeric middle body. The substantially cylindrical insert includes a top surface opposite a bottom surface and a substantially cylindrical coupling element that extends from the bottom surface, a primer recess in the top surface that extends toward the bottom surface, a primer flash hole positioned in the primer recess to extend through the bottom surface, and a flange that extends circumferentially about an outer edge of the top surface. The substantially cylindrical polymeric middle body includes a substantially cylindrical polymeric bullet-end and a substantially cylindrical polymeric coupling end connected by a powder chamber, wherein the substantially cylindrical polymeric coupling end extends over the substantially cylindrical coupling element and covers a circumferential surface of the primer flash hole.

The present invention includes a powder compaction device comprising a loading platform positioned above a lower platform; a compaction rod aperture positioned in the loading platform; a vertical tube positioned in communication with the compaction rod aperture; a compaction rod positioned in the compaction rod aperture and extending through the compaction rod aperture, wherein the compaction rod comprises one or more reliefs having a powder volume; a drive motor in communication with the vertical tube and connected to the compaction rod to move the compaction rod through the compaction rod aperture; a first funnel-shaped device positioned below the loading platform, wherein the first funnel-shaped device comprises a first funnel aperture, wherein the first funnel aperture aligns with the compaction rod aperture to move the compaction rod through the compaction rod aperture and the first funnel aperture; an adaptor platform secured to the lower platform and aligned with the compaction rod aperture; an ammunition cartridge fixture slidably secured in the adaptor platform, wherein the ammunition cartridge fixture comprises a funnel-shaped opening, an interior cartridge shaped void, and a funnel aperture connecting the funnel-shaped opening to the interior cartridge shaped void, wherein the funnel aperture is aligned with the compaction rod aperture and the first funnel aperture to accommodate the compaction movement of the compaction rod; an ammunition cartridge positioned in the ammunition cartridge fixture; a powder reservoir positioned in communication with the first funnel-shaped device to transport powder to the first funnel-shaped device; a compaction controller in communication with the drive motor and one or more sensors to control the direction of the motor to control the direction of movement of the compaction rod and the force applied to the compaction rod to control the compaction of the powder; and a powder metering controller in communication with the gate and one or more second sensors to control the amount of powder delivered and he powder is despised.

A solid state illuminator can be used for a variety of surgery procedures, such as retinal surgery. A retinal illumination system my have at least one light emitting diode located on a substrate with the substrate positioned on an eye of a patient. A light pipe can continuously extend from the light emitting diode into a sclera of the eye via a cannula. A system controller may be configured to activate the light emitting diode to illuminate an interior of the eye.

Retinal illumination system

A tactile sensor in which the sensor elements are discrete, elastomeric, electrically conductive, electrically force-sensitive forcel units electrically insulated from one another, each forcel unit defining a local force-resolution region (forcel) for resolving a deflection pattern in the surface of the sensor, each sensor element being connected between a pair of electrical channels which produce a set of signals representative of the deflection pattern in the surface; a sensing system for determining a parameter of an object being contacted by the tactile sensor; and a method of fabricating the sensor.
