Abstract: A system for firing multiple projectiles in a parallel or diverging manner is provided. The system can comprise tail-end portions of projectiles that add structure to a cartridge, provide for efficient combustion, allow projectiles to transition from a straight configuration in the cartridge to a splayed configuration in a chamber, and ensure complete evacuation of the chamber. The system can include a tail-end portion of a particular projectile with openings that distribute energy from combustion of an ignition charge, facilitating firing of multiple projectiles. A tail-end portion of a projectile can include a ball joint upon which the body portion of the projectile moves causing an angle between the body portion and the tail-end portion. A space can exist in the body portion adjacent to the ball joint to allow off-center shifting of the body portion with respect to the ball joint.

Abstract: A bipolar pulse generator is implemented in a simple structure while providing a high efficiency design having a relatively low total size, while still allowing access by fibers used to control a photoconductive switch that activates the generator. The bipolar pulse generator includes a stacked Blumlein generator structure with an additional transmission line connected to a load at its near end and short-circuited at its distal end. An extra transmission line is positioned between the Blumlein generator's structure and the load provides specified limited gap between positive and negative sub-pulses. The bipolar pulse generator further includes a bended Blumlein generator structure, in which an existing intrinsic “stray” transmission line is used to provide the bipolar pulse. Still further, bipolar pulse generator includes stepped transmission lines, with additional switches positioned between steps, which are charged by different voltages.

Abstract: An apparatus and method is provided to dynamically search for available Web services by persistently searching a distributed multi-level UDDI registry chain, interrogating their published technical specifications and enabling the consumer to find, bind, and invoke the desired Web service in real-time and without intervention by the consumer. The search criteria includes identifying candidate published services that fall within an acceptable margin of error based on information previously published within a consumer service profile. The measure of conformance between the registry semantic map and consumer service profile is parameterized and chosen by the consumer in advance. The service profile includes an XML schema which exposes consumer profile metadata and corresponding information sets used by a rules engine for pattern matching purposes.

Abstract: A method and apparatus is provided for using a distributed multi-path QoS-aware routing scheme that considers basic MANET characteristics to meet transport service requirements of real-time applications and makes use of multiple discovered paths to calculate a next-hop decision. The QoS Routing scheme superimposes distributed neighborhood congestion, neighborhood density, and link stability and delay information over the multiple discovered paths when the next-hop decision is calculated.

Abstract: A bipolar pulse generator includes a pair of two-conductor transmission lines coupled together with a load positioned between the two transmission lines. Two segments of one transmission line are charged and switchably coupled to two segments of the other transmission line to produce a bipolar pulse on the matched load. The generator may include two transmission line structures coupled together with a load positioned between each transmission line structures. The first transmission line structure may include a stepped transmission line and an embedded transmission line segment. A switch is coupled between the embedded transmission line segment and another segment of the transmission line structure. During operation, the first transmission line structure is charged to a potential with the switch in the open position and, when the switch is closed, the charge on the first transmission line structure together with the second transmission line structure generates a bipolar pulse on the matched load.

Abstract: Hard material can be displaced by firing a frangible projectile from a firing device. The projectile has a rear portion that engages the bore of the barrel of the firing device and a front portion that is rotatably journaled to the rear portion. The front portion can be frangible to allow maximum displacement of the hard material. Specifically, the front portion has a core and a plurality of fins extending from the core. At impact, as the fins penetrate the target, the fins separate from the core and spread radially outwardly from the core.

Abstract: There is provided an electronic music apparatus that can make effective use of song data by separately controlling external outputting of the song data according to songs while protecting the rights. When song data is selected, the song data is read from a second ROM or a flash memory and written into a RAM together with a copyright flag CRF indicating that the song data has a copyright, when it is set to “1”. When an external output instruction is given, when the copyright flag CRF corresponding to the selected song data is set to “0”, it is judged that the song data has no copyright to be protected. Then, the song data is output according to the external output instruction. On the other hand, if CRF=1 holds, it is judged that the song data has a copyright to be protected, and then an output inhibition message is displayed to inhibit external outputting of the song data.
