摘要:
A method, computer program product, and device for detecting a reconnaissance of a network through the identification of the information flowing from the network to external sources are provided. The method may include monitoring the information flowing from the network to external sources in order to identify what properties may have been revealed to a potential attacker. The method may include monitoring a response of the network to an inquiry from an external source, determining potential properties of the network that may have been revealed from the response, storing the potential properties in a data repository, and determining a possible reconnaissance of the network based on the properties stored in the data repository. Determining the potential properties of the network revealed by the response may include comparing the response to one or more information templates. Each information template may be associated with one or more properties of the network.

A capacitor assembly (1) for measuring the level of radio frequency voltage in a mass spectrometer. The assembly (1) includes an RF sensing capacitor (2) with first and second capacitor plates (3, 4), a rectifying circuit (5) and a vacuum housing feedthrough (6), all of which are mounted within a vacuum enclosure of the mass spectrometer. The first capacitor plate (3) is adapted for connection to a voltage source and mounted within the enclosure by first insulating spacers (31). The second capacitor plate (4) is nested within the first insulating spacers (31) and mounted within the enclosure by second insulating spacers (41). The rectifying circuit (5) is electrically connected to the second capacitor plate (4) and to the vacuum housing feedthrough (6).

An approach is provided for distributing video signals. A digital video feed is received at a media distributor that includes a plurality of decoders and a corresponding plurality of modulators, wherein the digital video feed includes a plurality of video channels. The decoders decode the digital video feed to output analog video signals. The modulators modulate the analog video signals; and a combiner combines the outputs of the modulators to generate a channelized video signal.

An approach for tracking documents using image processing is disclosed. Auxiliary information corresponding to compressed digital information is extracted. The auxiliary information is used to output text lines, which undergo a hash function (e.g., checksum operation). In this manner, individual hash values are generated, as well as an overall hash value of the entire file of text lines. A reference set of hash values are maintained to identify other compressed digital information.

An ion source, a mass spectrometer and a method of enhancing the performance of an ion source for use with a mass spectrometer. The ion source has a housing incorporating an ion source enclosure defining a chamber and an outer cover remote from the chamber. A fluid flow passageway is provided between the ion source enclosure and the outer cover. The method of the invention comprising supplying to the ion source housing a regulated flow of fluid through the fluid passageways so as to maintain the ion source enclosure within a predetermined temperature range of substantially between 60° c. and 80° c. and preferably at 70° c.
