  • Patent number: 12341805
    Abstract: The present disclosure generally relates to systems and methods for utilization of network mitigation techniques in the form of null address routing to mitigate coordinated DDOS attacks. One or more computing devices can install malware code into a network device after exploiting a vulnerability of the network device. A monitoring and mitigation service can monitor network devices and detect malware code installed on the network-based service. The monitoring and mitigation service can identify the internet protocol (IP) address or any routing information regarding the computing devices that sent the malware code. Based on the identified information, the monitoring and mitigation service can identify and implement the network mitigation information in the form of null routing addresses that will cause network communications associated with the identified computing device to be terminated or otherwise not delivered to the intended network-based resources.

  • Patent number: 12170688
    Abstract: A distributed denial of service attack is detected. In response to detection of the attack, application layer properties of network traffic associated with a web application under attack are analyzed. Changes to distributions of the application layer properties are identified. A signature is generated based, at least in part, on identifying a combination of application layer properties whose distributions have changed, and which identifies traffic increased since onset of the attack. A mitigation rule is generated based, at least in part, on the signature.

  • Patent number: 12155690
    Abstract: The present disclosure generally relates to systems and methods for utilization of network mitigation techniques in the form of null address routing to mitigate coordinated DDOS attacks. A monitoring and mitigation service can characterize a command and control node as compromised or otherwise manipulated for purposes of generating distributed attacks. The monitoring and mitigation service can then identify network mitigation information in the form of null routing addresses that will cause network communications associated with the identified command and control node to be terminated or otherwise not delivered to the intended network-based resources. The monitoring and mitigation service can propagate the null routing address to routing components. The network mitigation information can be associated with expiration criteria for the routing components that receive and implement the network mitigation technique.

  • Patent number: 6435450
    Abstract: A multi-compartment paralleling reel that allows different sets of wire to be drawn from the paralleling reel independently of each other. The multi-compartment paralleling reel includes a plurality of independent compartments. Each independent compartment can store a set of wire. A shaft mounted through the plurality of independent compartments allows each independent compartment to rotate relative to the shaft and allows each independent compartment to rotate independently of the other independent compartments. Thus, each set of wire can be drawn from each independent compartment of the multi-compartment paralleling reel independently of the other independent compartments. This allows the different sets of wire, which may include wires that have different diameter sizes, to be drawn from the independent compartments at different rates of speed or the same speed, depending upon what is desired.

  • Patent number: 5241178
    Abstract: Apparatus for quantitative analysis of a material sample, such as whole grain, as a function of optical characteristics thereof includes a light source and a solid state detector of silicon or other suitable construction. A material sample is positioned between the light source and the detector, and light energy is focused through the sample onto the detector at a plurality of preselected wavelengths in the near-infrared range of 800-1100 nm. Illumination wavelength is selectively controlled by an opaque disc having a central axis and a plurality of apertures around the periphery at uniform radius from the disc axis. A plurality of filter elements are carried by the disc over respective ones of the peripheral apertures and have transmission characteristics corresponding to the plurality of preselected wavelengths.

  • Patent number: 5108213
    Abstract: A clamping assembly for connecting a support rod that supports medical accessories to a medical table, the clamping assembly having independently operable adjustments for releasably securing the assembly to the rail of the medical table; controlling the rotational positioning of the support rod; and regulating the longitudinal displacement of the support rod. The assembly includes a cam handle that regulates a camming surface. When the cam handle is rotated the camming surface translates a locking lug within an aperture of the assembly until the locking lug engages the rail of the medical table whereby the assembly is secured to the rail. The locking lug may be released from the rail by rotating the cam handle in the opposite direction. The rotational movement of the support rod relative to the housing of the assembly is controlled by the interaction of a toothed locking ring disposed upon a shaft extending from the housing and a set of circumferentially disposed teeth fixed upon the housing.

  • Patent number: 4825076
    Abstract: An optical cell and detector assembly for a spectrophotometric analyzing apparatus which comprises a sample cell having walls of optically transparent material defining a sample cavity having closely adjacent the sample cavity a radiation detector and adjacent an opposite wall a lens whereby to focus radiation passing through the cell onto the detector. The apparatus may also comprise optical means for focussing the beam onto the sample cell, chopper means for periodically obscuring the beam, and filter means for selecting one or more wavelengths from the beam. The sample under test is an aqueous emulsion and the filters are chosen to determine the concentration of the non aqueous components of the emulsion by measuring the water displaced by the components.

  • Patent number: 4663530
    Abstract: An infrared transmission/absorption technique for the quantitative determination of fat in dairy products, particularly high-fat dairy products having fat concentrations between 15 and 60 w/o. A wave band characteristic of bending and scissoring of saturated carbon hydrogen bonds is employed, preferably a wave band at about 6.84 microns. It is further preferred to use the double wavelength, single cuvette system. Variations in accuracy caused by lipolysis and degree of homogenization are substantially reduced.

  • Patent number: 4447725
    Abstract: Electro-optical apparatus for measurement of fat, protein, lactose and solids in milk wherein a milk sample in a test cell is irradiated with reference and measurement beams at differing wavelengths for fat, protein and lactose, and signals are stored indicative of uncorrected concentrations. A scaling and correction circuit includes cross-correction circuitry for compensating the effects on each reading caused by the other constituents. The signals so corrected are then provided in percentage by weight or weight over volume on suitable digital displays. For enhanced accuracy of fat concentration, infrared absorption is measured at both the carbon-hydrogen stretching wavelength (3.48 microns) and the wavelength of absorption at the ester linkages (5.72 microns), and the resulting readings are combined in a predetermined function for obtaining a reading of fat concentration.
