Touch systems and methods utilizing customized sensors and genericized controllers
First Claim
1. A method of manufacturing touch sensing circuit arrangements, each touch sensing circuit arrangement including a sensor to generate touch-related signals responsive to a touch input to the sensor, and a controller board to determine touch positions based on the touch-related signals, the method comprising:
- producing a plurality of different sensors, each of the different sensors customized by including a memory device storing computer-executable firmware instructions executable by the controller board for determining touch positions;
producing a plurality of controller boards, each controller board including a processor circuit and further including query logic executable by the processor circuit to cause the controller board to query for the computer-executable firmware instructions stored on the memory device of the associated one of the plurality of different sensors; and
assembling a touch sensing circuit arrangement that includes one of the plurality of different sensors and an associated one of the plurality of controller boards, such that the processor circuit of the one of the plurality of controller boards determines touch positions by executing the computer-executable firmware instructions retrieved from the memory device of the associated one of the plurality of different sensors in response to the query.

Abstract
Touch sensing circuit arrangements include a touch sensor and a controller board. The touch sensor includes one or more sensing elements to generate touch-related signals responsive to a touch input to the sensor, and a memory device storing computer-executable firmware instructions for determining touch positions based on the touch-related signals. The controller board includes query logic executable by the controller board to cause the controller board to query for the computer-executable firmware instructions stored on the memory device of the touch sensor, and a processor circuit to determine touch positions by executing the firmware instructions loaded onto the generic controller board in response to the query.
