Abstract: Methods and corresponding devices for packets classification featuring pattern recognition, and not content recognition or port matching. The methods and corresponding devices are able to recognize traffic in the background and/or offline, without overloading the system.

Abstract: A system for optical scanning along one line with fast random access and high optical resolution, composed of: a plurality of first lenslets (240) constructed for use with a selected media format (224), the plurality of lenslets (240) all being disposed in a single row and being spaced apart by a given center-to-center distance; a movable mount carrying the plurality of lenslets (240), a linear motion actuator (241) coupled to the mount for moving the mount in a direction substantially parallel to the single row over a distance having a maximum value that is substantially equal to or slightly greater than the given center-to-center distance; at least one light source (260); a light directing unit (234) for directing light from the source to any one or two selected lenslets (240); and a control unit for controlling the light directing unit (234).

Abstract: Apparatus for scanning a rotating optical disk, including: a scanning assembly for directing a light beam toward the disk surface and causing the beam to traverse the surface; a focusing lens unit disposed in the path of the beam to focus the beam at the surface; and a light beam deflecting element disposed in the beam path between the scanning assembly and the focusing lens unit to deflect the beam toward a direction perpendicular to the surface. The focusing lens unit may be composed of a group of individual focusing lenses spaced apart parallel to the surface, each having an optical axis that is perpendicular to the surface and each being associated with a respective track; and light directing elements disposed in line with the path at a location for directing light substantially entirely to a respective one of the individual lenses.
