摘要： Information is provided in a multilayer identification card by means of a laser beam. This information is recorded by irreversibly changing (blackening) transparent synthetic material. Synthetic materials which blacken at different intensity values are used for the individual card layers. By controlling the laser beam intensity, information can thus be recorded only in one layer or else simultaneously in several layers. If the layer arrangement, layer materials and recording parameters (intensity, writing width, etc.) are selected appropriately, images can be produced which change their appearance when the viewing angle is changed. The various visual effects which can thereby be otained serve to distinguish the authenticity of the identification card.

摘要： A method of transforming serial binary data exchanged between facsimile transceivers having different horizontal resolutions. Binary signal elements representing a scanning line are separated into a sequence of n bit data words and the number and type of subsequent bit changes within each data word is derermined. A conicident sequence of m bit data words is generated such that the bit pattern of each corresponding n bit data word substantially is reproduced by arbitrarily padding of an insignificant bit if n m; wherein n:m corresponds to the ratio of the transceiver resolutions. The serial data stream is reproduced from the sequence of said second data words and transmitted to the receiving facsimile transceiver for recording.
