  • Patent number: 7570625
    Abstract: A method, system, apparatus, and computer-readable medium to determine whether a device having access to a network is wireless. A method for determining whether a device is wireless includes sending a specially-constructed packet to the device via a network. The packet is constructed so that the source address for the packet is a physical address on the network for the device. If the device does not send a response to the packet, a determination is made that the device is wireless. If the device sends a response to the packet, a determination is made that the device is wired. In one embodiment of the invention, the physical address for the device is a Media Access Control (MAC) address. The initial packet may, for example, request the physical address for the device and may be sent in response to detecting a communication to or from the suspect device.

  • Patent number: 7546977
    Abstract: An aircraft capable of supersonic flight comprises a body portion including a fuselage, a wing, and an engine nacelle mounted below the wing. The aircraft may also include a high-mounted aft, tail. The area/lift distribution of the body portion is tailored to reduce sonic boom disturbance. The body portion further includes a blunt nose and a gull dihedral wing configuration that further reduces sonic boom disturbance and eases constraints on area/lift distribution tailoring. The gull dihedral wing or tail is configured to carry lifting force to its trailing edge to create an expansion at the aft end of the aircraft that reduces aft sonic boom ground shock strength. The volume of the mid-portion of the fuselage can be reduced above the wing to create a sloped surface that generates an expansion fan over the wings.

  • Patent number: 7506360
    Abstract: A system and method for tracking communication for determining device states. Communication between devices is observed and a respective state of at least one device is inferred. The inference is formed without directly communicating with the device. Various states of the devices include unknown, used, unfulfilled, virtual, omitted, and automatic. The respective state of a device is unknown when the observation shows that the device fails to respond to communication. The respective state of the device is unfulfilled when an ARP request comprising a destination address for the device is observed, and the device does not respond to the ARP request prior to expiration of a time limit. The respective state of a device is determined to be virtual when the observation shows that the device received a packet when its respective state was unfulfilled, and the device did not send a reply to the packet within a time limit.

  • Patent number: 7500116
    Abstract: The present invention provides a method to at least partially power an Ethernet device from a plurality of balanced network power signals received through a network connection. This involves attaching the network device to the network, wherein network signals are received and contain both power signals and/or data signals. These network signals may be passed through surge protection and power-conditioning circuitry wherein the output of these circuits may be provided to a power absorbing circuit. This power absorbing circuit may separate the communication signal and power signal from the network signal. The communication signal may be passed to a network physical layer while the power signal may be passed to a power distribution module. Additionally, because certain embodiments may provide multiple pairs of network power signals to the power absorbing circuit, the current or power associated with each power signal must be sensed and balanced. This may be done with an active control circuit.

  • Patent number: 7469418
    Abstract: A system, method, and computer-readable medium for deterring network incursion by formulating appropriate responses to attacks. Once an attack is detected, the system may respond in such a manner as to imitate a network device. The system may respond in a manner that provides a high cost to pursue further communication with the system. For example, the system may respond to TCP syn requests and window probes with messages indicating small packet and window sizes. As such, attempts to send packets to the system have a high network and processing cost. An attacking computer running multiple threads may ultimately slow or be disabled as a result of the receiving the responses and attempting to continue to communicate with the system.
