Pre-rendered “after” model images using an appropriate VTO engine show the product/services. The after model images can be presented prior to a live user image experience enabled by a corresponding user device executed VTO engine rendering a product instance to a user image. The model experience can be presented while the user image experience (e.g. its VTO engine) is readied. The model experience can be presented in a same/overlapping region as the user image experience, for example.

Abstract: Signal lines in the pin field of a printed circuit board layout are modified to reduce line impedance and improve signal integrity. The widths of signal lines are extended in the pin field to take full advantage of the available routing space between pads and adjacent signal lines.

The edge of a signal line is extended to a keep-out region associated with a centerline that extends through a plurality of pads arranged in a line and located adjacent to the signal line. The edge of the signal line is also extended to keep-out regions associated with pads in the pin fields.
