Abstract:

In a pipeline network processor, a packet intercept feature determines whether a packet is to be intercepted based on the inbound and outbound port through which the packet travels and based on the source and destination of the packet. When a packet enters the pipeline network processor, a determination is made as to whether the inbound and outbound ports are enabled for packet intercept. If so, a source and/or destination media access control address is compared to a list of configured intercept addresses. If a match is found, a copy of the packet is diverted to an intercept receiver and the original packet is forwarded to its intended destination.

Abstract:

An opposed dipole magnet assembly is provided that exhibits higher magnetic field uniformity than traditional magnet assemblies, such as H-shaped magnet assemblies. The opposed dipole magnet assembly includes two permanent magnets that are spaced apart and oriented such that their respective magnetization directions are parallel. Plates formed of a high permeability material are attached to top and bottom surfaces of the two permanent magnets so as to form a hollow field region. With this geometry, the magnetic field in the hollow field region is in a direction antiparallel to the magnetic field directions of the two permanent magnets.

International Classification:

H01J 49/32

Abstract:

Disclosed herein are mass spectrometers having segmented electrodes and associated methods. According to an aspect, an apparatus or mass spectrometer includes an ion source configured to generate ions from a sample. The apparatus also includes a detector configured to detect a plurality of mass-to-charge ratios associated with the ions. Further, the apparatus includes segmented electrodes positioned between the ion source and the detector. The apparatus also includes a controller configured to selectively apply a voltage across the segmented electrodes for forming a predetermined electric field profile.
