An information transponding device in communication with an emergency number answering point, an ALI database and a remote storage device. In order to improve accuracy, it has been found that measurements in at least three frequency ranges between 1 kHz and 200 kHz, 0. For each of the plurality of identification marking elements there is an opening in the workpiece identification marking mold of the device, through which thermal radiation can be applied to the surface of the workpiece to generate an image point, so that material that extends through the opening extends into the opening. Related methods, systems, and computer program products are also discussed. The upper interconnection line is electrically connected to the intermediate plate. The output signal and the composite can be blended in response to the power of the real and filtered signals Radio receivers that utilize the above method are also included.
