Abstract:
Improved radiation therapy with field-in-field multi-leaf collimator, utilizing leaf sequencing Field-in-Field's (FIF) to accurately reproduce the input fluence map or original optimized dose distribution. The number of apertures used is constrained to a user-specified value all the way down to as few as 2 apertures which significantly magnifies the effect of poorly formed apertures. The disclosed invention further includes producing fluence maps with a homogenous dose throughout the treated volume utilizing leaf-sequencing Field-in-Field that reproduces more precise input fluence maps to yield optimized dose distribution.
Abstract:
A connector is provided for simultaneously improving both the NEXT high frequency performance when low crosstalk plugs are used and the NEXT low frequency performance when high crosstalk plugs are used. The connector includes PCB substrates made of materials having different dielectric frequency characteristics.
Abstract:
A combination includes: (a) a communications module including: a housing; a printed wiring board mounted within the housing; a plurality of RJ-45 jacks mounted on the printed wiring board and accessible from one side of the housing; and a single module connector mounted to the printed wiring board and electrically connected to the RJ-45 jacks, connector being accessible from a second side of the housing; and (b) a cable-connector assembly including: a cable comprising a plurality of subunits, each of the subunits comprising a jacket and a plurality of twisted pairs of conductors positioned within the jacket; and a single cable connector mounted to the printed circuit board and electrically connected to the conductors of the cable subunits. The module connector is attached to the cable connector.
Abstract:
Communications connectors having a plurality of signal carrying paths include a printed circuit board and a plurality of contacts. The printed circuit board has a plurality of contact pads, a plurality of output terminals, and a plurality of conductive paths that electrically connect at least some of the plurality of contact pads to respective ones of the plurality of output terminals. The contacts each have a plug contact region. In these connectors, a first of the plurality of signal carrying paths extends from the plug contact region of a first of the plurality of contacts to a first of the plurality of output terminals through a first of the contact pads and a first of the conductive paths.
