Abstract: A method of interacting with a managed data network entity is provided. The method includes a sequence of steps. A change in the operational state of the managed data network entity is detected. A CLI dictionary entry is retrieved form a CLI dictionary associated with the data network entity. Based on the retrieved CLI dictionary entry, CLI commands are extracted therefrom to configure the managed data network entity to reflect the detected change in the operational state. A CLI command sequence is built from the extracted CLI commands. Each CLI command in the command sequence is sent to the managed data network entity for execution. CLI command responses are monitored. Based on a successful execution of CLI commands send, subsequent CLI commands in the CLI command sequence are sent for execution. The solution provides automated configuration management of data network entities from different vendors when SNMP is not a viable option.

Abstract: Methods of detecting TCP SYN flooding attacks at a router located between a LAN and a network such as the Internet are described. The methods rely on a counting arrangement in which SYN and Fin packets are counted on both the LAN side and the network or Internet side of the router during a time interval. Weighting factors are applied to each count, the factor for the LAN side count having the opposite polarity to the factor for the network side count. The absolute values of the sums of the weighting factors of like polarity are equal. An abnormal number of unsuccessful connection attempts are determined based on a parameter calculated using the weighting factors in conjunction with the respective counts.

Abstract: Apparatus for high resolution imaging of a moving object comprises a source of low coherence light, an optical coherence tomography imaging instrument or a dual channel, optical coherence tomography/confocal imaging instrument, a transverse scanner, an interferometer, depth adjustment means, and interface optics. First and an optional second sensing blocks sense the axial and respectively the transverse position of the object. A splitting element is shared so that the interface optics and the sensing blocks have a common axis of light transmitted to and from the object. Timing means establishes a timing, and timing intervals and reference times for images as they are taken. The acceptability of each scanned image is determined according to predetermined criteria. A series of en-face OCT images, or of longitudinal OCT images of the object may be taken at different depths or transverse coordinates, and the stack of collected images is used to build 3D profiles of the object.

Abstract: The porous material of the present invention is produced by heating a dry powder mixture, containing mainly an organic solid binder and inorganic particles. The mixture is foamed while the organic binder is melted. Foaming comes from a foaming agent in the powder mixture. The solid foamed structure comprising inorganic particles embedded in an organic binder is then heated to eliminate the organic binder and finally to sinter the remaining inorganic tri-dimensional network into a rigid structure having interconnected porosity.

Abstract: A method of making an organic light emitting device (OLED) is disclosed wherein an inert insulating conformal smoothing layer is deposited over a protruding structure. The smoothing layer is patterned to expose portions of the structure underlying the smoothing layer and defining active regions of the device. The inert smoothing layer is treated, preferably by heat reflow, to taper the layer over the stepped edges of the structure on the exposed portions. Additional layers are then deposited over the smoothing layer and the exposed portions of the structure. The smoothing layer blunts all underlying layer edges and provides sloped edges wherever a step occurs from one layer to another. This effect results in a homogeneous field across the pixel and the continuity in the layers deposited after the photoresist layer.

Abstract: A method of extracting a tomographic image of a layer within a body by optical coherence tomography, involves capturing three images, namely a non-interference background image, a first interference-fringe image of said layer, and a second interference-fringe image phase-shifted relative to the first interference-fringe image. The tomographic image is obtained by mathematically combining the three captured images. In a preferred embodiment random noise is removed by averaging and inter-layer effects are removed by applying a compensation function. This system is then used to extract the 2D cross-sectional images encoded in a multiple-layer information carrier.

Abstract: The present invention increases the aperture size of a microphone array by introducing a diffracting structure into the interior of a microphone array. The diffracting structure within the array modifies both the amplitude and phase of the acoustic signal reaching the microphones. The diffracting structure increases acoustic shadowing along with the signal's travel time around the structure. The diffracting structure in the array effectively increases the aperture size of the array and thereby increases the directivity of the array. Constructing the surface of the diffracting structure such that surface waves can form over the surface further increases the travel time and modifies the amplitude of the acoustical signal thereby allowing a larger effective aperture for the array.
