  • Publication number: 20140240702
    Abstract: Embodied is a two-color, fiber-delivered picosecond source for coherent Raman scattering (CRS) imaging. A wavelength tunable picosecond pump is generated by nonlinear spectral compression of a prechirped femtosecond pulse from a mode-locked titanium:sapphire (Ti:S) laser. A 1064-nm picosecond Stokes pulse is generated by an all-fiber time-lens source (or suitable alternative source) that is synchronized to the Ti:S laser. The pump and Stokes beams are combined in an optical fiber coupler, which serves not only as the delivery fiber but also as the nonlinear medium for spectral compression of the femtosecond pulse. CRS imaging of mouse skin is performed to demonstrate the practicality of this source.

  • Publication number: 20140196147
    Abstract: A method, apparatus and medium are provided for detecting anomalous payloads transmitted through a network. The system receives payloads within the network and determines a length for data contained in each payload. A statistical distribution is generated for data contained in each payload received within the network, and compared to a selected model distribution representative of normal payloads transmitted through the network. The model payload can be selected such that it has a predetermined length range that encompasses the length for data contained in the received payload. Anomalous payloads are then identified based on differences detected between the statistical distribution of received payloads and the model distribution. The system can also provide for automatic training and incremental updating of models.

  • Patent number: 8725079
    Abstract: An interference analysis tool for identifying an interference problem area in a cellular radio network in which at least a first User Equipment (UE1) and a second UE (UE2) operate. The tool receives signal quality measurements and determines uplink or downlink interference severity. For UE2 uplink interference, the tool determines a first uplink Signal-to-Interference-and-Noise-Ratio (SINR) experienced by UE2, wherein the first SINR includes uplink interference from UE1. The tool also determines a second uplink SINR level (SINR0) experienced by UE2, wherein SINR0 does not include the uplink interference from UE1. The tool calculates a difference (?SINR) between SINR and SINR0 for UE2, and identifies the area where UE1 is operating as an interference-causing area when the ?SINR for UE2 is greater than a threshold value. The tool may present interference severity levels to an operator, and may initiate Radio Resource Management (RRM) procedures to mitigate interference problems in the network.
