A toy building system with function bricks

Abstract From the Canadian patent

A toy building system with function bricks adapted to perform a function in response to a mechanical trigger action; sensor bricks with a sensor adapted to produce an output in response to a mechanical trigger action; and logic bricks with an input responsive to a sensor brick output and adapted to perform a logic function on the sensor brick output and to produce a logic output. The sensor brick output and the logic brick output are arranged in a first uniform manner relative to the coupling means and the sensor output , action and the logic output action are of uniform physical nature. The logic brick input and the function brick input are arranged in a second uniform manner …
