Hydrogen is stored by adsorbing the hydrogen to a carbon nanomaterial that includes carbon nanospheres. The inventive method includes the feature that in pre-selecting individual transponders or sensors by at least one reading device and, after the successful selection of at least one transponder or sensor, data, in particular for conforming the preselection, is asynchronously transmitted during at least one protocol section from the transponder or sensor to the reading device. The intermediate section of the tee is also preferably bendable so that the head section will easily move out of the way as it is struck by the golf club. Visible light optics and a visible light sensor array provide a scene image to an image processor that determines the iris location. Detachment of the detachable component cause an input voltage to change on the portable device. Further, since the majority of the applied voltage in a device according to this invention is dropped over the gate dielectric, rather than shared between the gate dielectric and a depletion layer in the gate poly, the device of this invention can be scaled in gate dielectric thickness without significantly compromising the program speed.
