Abstract: An improved barrel clamp assembly for a multi-barreled minigun includes a barrel clamp tube having a front end, a rear end, and a plurality of longitudinal openings extending along a portion the length of the tube between the front end and the rear end. An impeller is mounted in the barrel clamp tube between the tube front end and the tube rear end. The impeller includes a plurality of impeller blades that are spaced around a periphery of the impeller and that project forward from a rear flange portion of the impeller and the impeller blades define a plurality of air channels. A barrel assembly includes the barrel clamp tube, a flash suppressor mounted to the front end of the barrel clamp tube, and a barrel clamp collar mounted to the rear end of the barrel clamp tube. The impeller is mounted to the barrel clamp tube between the flash suppressor and the barrel clamp collar.

Abstract: A delinking feeder of a minigun includes an access door mounted to a delinking feeder housing and movable between a closed position and an open position. The access door has an enclosed recess for receiving a tongue that is rotationally coupled to the access door and is movable between a retracted position and a deployed position. When the access door is in the open position, the tongue is in the deployed position and a tongue first contact surface can contact and secure a linked cartridge positioned in the delinking feeder. When the access door is in the closed position, the tongue is in the retracted position and a tongue second contact surface can contact and guide a cartridge positioned in the delinking feeder. The enclosed recess is covered so that when the access door is in the closed position, the tongue does not protrude through the access door.

Abstract: A computer has a processor and nontransitory memory. The computer receives a list of search keywords to propose to a search engine. For search keywords that are too infrequently used to have historical data to estimate keyword performance, the computer computes linguistic similarity between the sparse-data keyword to other keywords that have sufficient historical keyword performance data to permit a statistically sound estimate for keyword performance. The estimates are submitted to a search engine, and updated by grouping the sparse-data keywords into groups, including at least a high-performing group and a low-performing group, and reallocating budget from the keywords of the low-performing group to keywords of the high-performing group, by reducing estimates for keywords of the low-performing group and increasing estimates of keywords of the high-performing group.

Abstract: An improved delinking feeder receives a belt of linked cartridges, separates cartridges from the belt, and feeds the separated cartridges to a minigun for firing. The delinking feeder includes a feeder sprocket with a plurality of slots extending outward to an open end at an outer edge of the feeder sprocket body. Each of the slots is disposed along a curve. The curve decelerates a cartridge disposed in the slot as the cartridge moves outwardly in the slot. A feeder shaft is adapted to hold the feeder sprocket and a stripper. The shaft includes a section having a plurality of exterior splines, and the feeder sprocket includes an axial hole having a plurality of interior splines configured to mate with the plurality of shaft exterior splines. The stripper sleeve includes an axial hole having a plurality of interior splines configured to mate with the plurality of shaft exterior splines.

Abstract: An improved gun control unit for a minigun system includes a logic control module in communication with the minigun system, and a multi-function display for providing a visible display of information about the operation and status of the minigun system. The logic control module includes a processor coupled to the multi-function display, which processor is programmed to output a display signal to the display in response to status information received from the minigun system. The status information received from the minigun system can include: information for determining a count of rounds fired by the minigun system; information for determining a remaining level of ammunition: and/or information for trouble shooting the minigun system.

Abstract: A method and apparatus observes a mode register (102) in a synchronous memory device. A multiplexer (306) selects the value of the mode register (102) or the conventional data path of the memory array (302) through the output buffer. The invention outputs the stored value of the control register (102) on output pins, such as address pins when no signal is expected. The multiplexer (306) maybe responsive to a variety of control signals.
