Abstract: An apparatus is equipped to receive network traffic data for network traffic routed over one or more network links relevant to a network link. Selected numbers of analysis are performed to determine if the network link of interest is being misused. The analyses include but are not limited to analyses to determine whether the network traffic routed are inconsistent with an expected traffic pattern, whether unallocated source addresses are present, whether source addresses exhibit an uncharacteristic even distribution pattern, whether a server is uncharacteristically excessive in responding to the same source address, whether normal bursty behavior is absent from the traffic, whether a ratio of packets in one direction to packets in another direction is out of balance, whether a ratio of packets of one type to packets of another type is out of balance, and whether a server is uncharacteristically excessive in responding with error responses.

Abstract: In a crystal growth method, an enclosed growth crucible is provided inside of a growth chamber. The growth crucible has polycrystalline source material and a seed crystal disposed in spaced relation therein. The interior of the growth crucible is heated whereupon a temperature gradient forms between the source material and the seed crystal. The temperature gradient is sufficient to cause the source material to sublimate and be transported to the seed crystal where it precipitates on the seed crystal. A gas mixture is caused to flow into the growth crucible and between the polycrystalline source material and an interior surface of the growth crucible. The gas mixture reacts with an unwanted element in the body of the growth crucible to form a gaseous byproduct which then flows through the body of the growth crucible to the exterior of the growth crucible.

Abstract: In the growth of a SiC boule, a growth guide is provided inside of a growth crucible that is charged with SiC source material at a bottom of the crucible and a SiC seed crystal at a top of the crucible. The growth guide has an inner layer that defines at least part of an opening in the growth guide and an outer layer that supports the inner layer in the crucible. The opening faces the source material with the seed crystal positioned at an end of the opening opposite the source material. The inner layer is formed from a first material having a higher thermal conductivity than the second, different material forming the outer layer. The source material is sublimation grown on the seed crystal in the growth crucible via the opening in the growth guide to thereby form the SiC boule on the seed crystal.

Abstract: A server, using a deterministic function, a secret value and persistent information of a packet, destined for a client device, generates and includes a conversation identifier for inclusion with the packet. The client device in turn includes the conversation identifier in a subsequent packet sent by the client device destined for the server. An intermediate routing device having knowledge of the deterministic function and the secret value, upon receiving the packet en-route from the client device to the server, would independently determine whether the packet is a part of a conversation between the client and the server, by independently verifying the included conversation identifier, and forward or not forward the packet accordingly. As result, undesirable packets may be independently detected and filtered for the server.

Abstract: In a physical vapor transport growth technique for silicon carbide a silicon carbide powder and a silicon carbide seed crystal are introduced into a physical vapor transport growth system and halosilane gas is introduced separately into the system. The source powder, the halosilane gas, and the seed crystal are heated in a manner that encourages physical vapor transport growth of silicon carbide on the seed crystal, as well as chemical transformations in the gas phase leading to reactions between halogen and chemical elements present in the growth system.

Abstract: The present invention provides for a novel approach to protecting a system owner's system(s) from being exploited and providing involuntary assistance to a DOS attack. The present invention provides the protection by detecting and preventing undesirable or inappropriate network traffic from being sourced from a network domain. More specifically, a monitor/regulator is provided to monitor network traffic leaving a network domain. The monitor/regulator determines if undesirable/inappropriate network traffics are leaving the network domain based on the observed characteristics of the outbound and inbound network traffics. If it is determined that undesirable/inappropriate network traffics are leaving the network domain, the monitors/regulator, in one embodiment, at least warns system owners of the detection.

Abstract: A system for warning a pilot of a helicopter of a flight-into-terrain hazard includes a signal processing component that determines helicopter flight conditions by fusing data obtained from multiple flight condition data sources, a protection component that communicates with the signal processing component, determines whether a potential controlled flight-into-terrain hazard exists by computing predicted recovery trajectories based upon flight conditions and characteristics of the helicopter and decides upon a recovery trajectory, and a pilot interface component that provides a directive to the pilot to indicate the decided-upon recovery trajectory if multiple predicted recovery trajectories indicate a terrain impact will occur.

Abstract: A SiC single crystal is grown by physical vapor transport (PVT) in a graphite growth chamber, the interior of which is charged with a SiC source material and a SiC single crystal seed in spaced relation. During PVT growth of the SiC single crystal, the growth chamber further includes Ce. The SiC single crystal grows on the SiC single crystal seed in response to heating the interior of the growth chamber to a growth temperature and in the presence of a temperature gradient in the growth chamber whereupon the temperature of the SiC single crystal seed is lower than the temperature of the SiC source material. The Ce can include either Ce silicide or Ce carbide.

Abstract: One or more networking apparatuses are employed to practice a networking method that improves a first networking device's likelihood in meeting its service level goals/commitments for a first group of network traffic serviced by the first networking device. Determination is made, away from the networking device, on whether the first network device is meeting the service level goals/commitments for the first group of network traffic. Determination may include monitoring the first group of network traffic at or away from the networking device. If the service level goals/commitments are not being met, a second group of network traffic (also serviced by the first networking device) is regulated. Regulation may be made at the networking device or away from the network device. Additionally, if the condition for regulation is no longer presents, regulation may be moderated or removed. Further, the service level goals/commitments may include reliability and/or performance goals/commitments.

Abstract: A director is provided to receive source address instances of packets routed through routing devices of a network. The director determines whether any of the reported source address instances are to be deemed as spoof source address instances. The director further determines where filtering actions are to be deployed to filter out packets having certain source addresses deemed to be spoof instances. The director makes its determinations based at least in part on a selected one of a number of consistency measures. The consistency measures may include but are not limited to spatial consistency, destination consistency, migration consistency, and temporary consistency. The consistency measures are evaluated using spatial, destination source address range, migration and timing S/D/M/T distribution profiles of the reported source addresses.

Abstract: A process is taught for producing a smooth, damage-free surface on a SiC wafer, suitable for subsequent epitaxial film growth or ion implantation and semiconductor device fabrication. The process uses certain oxygenated solutions in combination with a colloidal abrasive in order to remove material from the wafer surface in a controlled manner. Hydrogen peroxide with or without ozonated water, in combination with colloidal silica or alumina (or alternatively, in combination with HF to affect the oxide removal) is the preferred embodiment of the invention. The invention also provides a means to monitor the sub-surface damage depth and extent since it initially reveals this damage though the higher oxidation rate and the associated higher removal rate.

Abstract: A number of sensors are distributively deployed in a network, either integrally disposed in a number of routing devices of the network or externally disposed and coupled to the routing devices, to monitor and report on network traffic routed through the routing devices. A director is provided to receive network traffic reports from the sensors for the routing devices, and to determine whether moderating actions are to be taken to moderate an amount of network traffic, based at least in part on some of the network traffic reports received from the sensors. In one embodiment, upon determining moderating actions are to be taken, the director further determines what kind of moderating actions are to be taken, including where the moderating actions are to be taken. In one embodiment, the director further instructs appropriate ones of the sensors to cause the desired moderating actions to be applied on the network traffic going through some of the routing devices.

Abstract: An apparatus is equipped to receive network traffic data for network traffic routed through a number of routing devices with one or more degrees of separation from a network node. The network traffic data include at least network traffic data for network traffic destined for the network node which meet a traffic type selection criteria and are routed by the routing devices to the network node. The apparatus is further equipped to progressively regulate and de-regulate network traffic routing by the routing devices based at least in part on the received network traffic data and the degrees of separation of the routing devices from the network node. Regulation extends from routing devices with the lowest degree of separation from the network node to routing devices with the highest degree of separation, following in the reverse direction of the routing paths traversed by the packets to reach the network node. In one embodiment, the extension or push back is made one degree of separation at a time.
