An integrated circuit includes a semiconductor die including a first magnetic field sensor. The multimodal fiducial marker generally comprises a first portion made from at least one radiopaque material and a second portion made from a porous material capable of absorbing at least one radioactive material. However, resists of the invention will crosslink during a post-development more stringent thermal treatment. When a predetermined number or configuration of cells of a group are earmarked, an award may be distributed to those gaming machines having earmarked cells according to the number of designators within that group associated with each gaming machine. A burst signal detector generates a pulse signal in response to electromotive force of a control secondary inductor.
