Abstract: For identifying an original object comprising a surface essentially made of a first substance in a forgery-proof way, atoms of a second substance not soluble in the first substance are deposited on the surface. The surface is subjected to a beam of energized atoms providing movability to the atoms of the second substance in the surface to allow for a nucleation of a phase separation of a phase, in which the atoms of the second substance are concentrated. Then, an image of a surface pattern originating from the nucleation of the phase separation is taken and stored as a identifier for the original object. When a comparison image of a surface pattern of some object supposed to be the original object is compared to the identifier, the object is confirmed as being the original object, if the surface patterns in the identifier and the comparison image are identical.

Abstract: A high-speed low-power latch includes three sets of transistors. A first set of transistors selects a tracking mode or a holding mode for the latch based on a clock signal having non-rail-to-rail or rail-to-rail voltage swing. A second set of transistors captures a data value based on an input signal and provides an output signal during the tracking mode. A third set of transistors stores the data value and provides the output signal during the holding mode. The input and output signals have rail-to-rail voltage swing. In another aspect, a signal generator includes at least one latch and a control circuit. The latch(es) receive a clock signal and generate an output signal. The control circuit senses a duty cycle of a feedback signal derived from the output signal and generates a control signal to adjust operation of the latch(es) to obtain 50% duty cycle for the feedback signal.
