Sensing devices with modular interconnection and programming
First Claim
1. A sensing device for the detection or measurement of objects, comprising:
- a direction dependent sense module having means for sensing objects within a sensitivity pattern along a predetermined sensing direction relative to said sense module, said sense module having a pattern of fixed electrical contacts thereon which connect to circuitry within the sense module;
a second module having a pattern of fixed electrical contacts thereon which connect to circuitry within the second module;
at least one of said sense module and said second module capable of operating in a plurality of discrete modes in response to connections to be made to its pattern of electrical contacts;
said sense module and said second module configured to fit together in a plurality of predetermined discrete orientations with said sensing direction rotated relative to said second module and with selected ones of the contacts of said sense module and said second module making electrical contact in different orientations of the modules to effect selection of one of said discrete modes of operation of said sense module or second module; and
means for holding said sense module and second module together in assembly in each of said plurality of orientations to form a sensing device operative in the selected mode according to the relative orientation of the modules.

Abstract
A sensing device constructed of two or more modules which can be connected together in different possible orientations to form a complete sensor. The modules have patterns of electrical contacts on adjacent faces such that different relative orientations of the modules effect interconnection of different contacts to program and select the mode of operation of the sensing device, from a plurality of available modes. In a preferred embodiment, a programming module having a connector bar is positionable between sense and control modules of the device in a plurality of different orientations to effect both programming mode selection and device orientation for mounting convenience.
