Abstract

This invention describes a method for building computer systems of various configurations directed at various different markets, from a set of pre-tested functional islands which can be fitted into a personalized framework. The advantages of this approach over conventional card on board techniques are flexibility to provide a large number of sizes, applicability to robotic construction, a high quality level by virtue of pre-tested sub-parts, and electrical characteristics comparable to a whole board.

Physically Configurable Planar Boards

      This invention describes a method for building
computer systems of various configurations directed at
various different markets, from a set of pre-tested functional
islands which can be fitted into a personalized framework. The
advantages of this approach over conventional card on board
techniques are flexibility to provide a large number of sizes,
applicability to robotic construction, a high quality level
by virtue of pre-tested sub-parts, and electrical characteristics
comparable to a whole board.

      The personalized framework is made of pre-molded
frame members which can be snapped or screwed together to provide
the required configuration. Pressure contact strips backed by
compliant materials, such as elastomers, form interconnection
bridges between functional islands. Card tabs and flex strip
connectors are mounted on the outer perimeter of the personalized
framework to allow for communication with other system components.

      A typical framework with various functional island regions
labeled, is shown in Fig. 1. The outer members A and B of the
framework contain card tabs and flex cable slots for external
connection to the rest of the system, and are built in
one piece.  Internal members C, D, and E, are made of two pieces, and
are recessed to accept the elastomer interconnect strips where
required.
Fig. 2 shows detailed breakdowns of the various segments used
to build the framework. Parts A and B, the ou...
