Abstract: Systems (1900) and methods (2300, 2400) for use in a network node (1901-1903). The methods involve: receiving a Data Communication (“DC”) from Data Link Layer Software (“DLLS”); identifying an IDentity Parameter (“IDP”) contained in DC which comprises a False Value (“FV”) specifying false information about the node or DC; obtaining a True Value (“TV”) specifying true information about the node or DC; replacing the FV with the TV to generate a modified DC; and forwarding the modified DC to Network Layer Software (“NLS”). The methods also involve: receiving a Data Unit (“DU”) from NLS comprising a Transport Layer Header (“TLH”) and a Network Layer Header (“NLH”) including TVs specifying true information about the node or FDU; obtaining a FV which specifies false information about the node or FDU; replacing a TV of DU with the FV so as to form a Modified Data Unit (“MDU”); and forwarding MDU to DLLS.

Abstract: A switch and methods for its use are disclosed. The switch includes input and output circuitry for receiving and forwarding data packets to computing devices connected to the network. The switch also includes a memory configured to store a number of tables relating the ports to the physical addresses of computing devices connected to the switch. The switch is capable of correctly forwarding data packets which specify false identity parameters. The switch is also capable of dynamic forwarding used to forward data packets across many paths to the destination. The switch is also capable of forwarding data packets to one of a number of output ports based on a comparison of at least one of the identity parameters that specifies false information to a table stored in memory.

Abstract: A method and apparatus for processing data messages in a dynamic computer network is disclosed. The method includes implementing a mission plan specifying a message type, a message generation location, and a message distance vector for false messages, receiving a data message that includes a plurality of identity parameters, and determining a message type and a message distance vector for the received message. The network device is configured to generate false messages and process received messages. If the message type is a false message and the distance vector of the false message has been exhausted, the data message is dropped. If the distance vector of the false message has not been exhausted, transmitting the false message in accordance with the mission plan.

Abstract: An electronic control system especially for non-linear loads, such as high pressure sodium (HPS) lamps, includes an active power factor correction circuit (APFC). The system provides a power factor correction of above 0.95; total harmonic distortion (THD) below 5%; lamp crest factor (LCF) close to unity; efficient power consumption and reliable open circuit voltage (OCV) under all power line conditions. A ballast would include integrated circuits (ICs) and a four-arm transistor bridge which is directly driven by integrated circuits. The bridge generates reversal of polarity to the load. An approximate average current feedback is derived from a load current. A resistor divider in parallel with the load provides voltage feedback. The average current feedback and voltage feedback are added together to provide an approximation of power consumed by the load, without the complex circuitry required for a true power feedback of current multiplied by voltage.

Abstract: A propeller hub assembly having a through-hub exhaust propeller hub characterized by an interior overlap zone defined by the composite interior dimensions of a selected number of conventional propeller hubs and optionally fitted with a removable exhaust ring and/or sized ventilation plugs. The hub assembly of this invention includes specially designed driver adaptors for insertion in the overlap zone of a universal propeller hub and accommodating corresponding conventional OEM factory thrust washers normally used in the conventional propeller hubs. The overlap zone design facilitates installation of the propeller hub assembly on any conventional lower unit outdrive utilizing the OEM factory thrust washers and corresponding driver adaptors. The exhaust ring and sized ventilation plugs facilitate optimum engine exhaust porting through the hub assembly for various applications, such as racing and other high performance operation.

Abstract: An exterior progressive shear shoulder assembly which is adapted for connecting a marine propeller to a propeller drive shaft in such a manner that a selected torsional resistance of the propeller with respect to the drive shaft is achieved. In one embodiment a driver engaging the propeller drive shaft also receives a driver adaptor that fits inside the propeller hub and drivingly engages the propeller through interfacing torsion members such as torsion ribs and/or selected sets of shear rods, each having a selected length, composition and resilience. In another embodiment the drive shaft directly engages the driver adaptor. In the event that the rotating propeller inadvertently strikes or is entangled in an underwater object, the fixed or replaceable torsion ribs and/or shear rods deform and may shear between the propeller hub and driver adaptor to allow rotation of the driver adaptor in the propeller hub and absorb the torque shock.

Abstract: A process for reducing the waiting-on-cement (WOC) time associated with the cementing of a casing string in an oil well involving the specific improvement of pumping into the well a highly retarded cement slurry containing a dispersed encapsulated accelerator, such as calcium chloride or anhydrous sodium metasilicate, wherein the encapsulating material is specifically selected such that it will melt at a temperature above the bottom-hole circulating temperature but below the bottomhole static temperature of the well to be cemented. Petroleum-derived waxes and petroleum-derived waxes in combination with vinyl resins, such as wax-compatible copolymers of ethylene and vinyl acetate, are particularly suitable as the meltable encapsulating material exhibiting excellent strength and abrasion resistance as well as serving as a moisture barrier. The improved process is particularly useful in cementing deep hot wells.
